The following explains the page content scroll processing method applied to a server as an example.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart of a page content scrolling processing method according to an embodiment of the present invention.
As shown in fig. 1, the page content scrolling processing method specifically includes steps S11 to S16, and the order of the steps in the flowchart may be changed or some steps may be omitted according to different requirements.
S11, obtaining the descriptive text corresponding to the page needing to be rolled, and generating the tree structure corresponding to the descriptive text.
The method comprises the steps of obtaining a text of a page needing scrolling processing, such as a descriptive text (html text), and generating a tree structure corresponding to the descriptive text according to the descriptive text. The tree structure may include a Document Object Model (DOM). The tree structure can comprehensively express the structure of the descriptive text, and facilitates the operations of accessing, modifying, adding, deleting and the like of the descriptive text, thereby accelerating the processing efficiency of scrolling the page content.
In some embodiments, the generating the tree structure corresponding to the descriptive text includes:

The attributes may include a TITLE class (TITLE), a text Class (CONTENT), a visual class (VISION), a BLOCK class (BLOCK), a hyperlink class (LINK), OTHER classes (OTHER), and the like, a label system is preset, the label system includes a plurality of attribute labels and label hierarchies corresponding to the attribute labels, such as a primary label, a secondary label, and the like, exemplarily, the importance degree corresponding to the attributes with the label hierarchy is also large, and the label system may be customized by a user. The higher the node hierarchy corresponding to the attribute with the higher importance. And generating a tree structure corresponding to the descriptive text according to the attribute tags corresponding to the attributes in the descriptive text, so that the tree structure can more accurately express the structure of the descriptive text.
And S12, traversing the tree structure layer by layer, and monitoring a plurality of attributes corresponding to the traversed layers in the tree structure.
Illustratively, the attribute values in the tree structure may be monitored by means of event (watch) monitoring, for example, the attribute values in the tree structure may be monitored by means of deep (deep) monitoring in event monitoring, that is, the tree structure is traversed hierarchically, and monitoring is added to each attribute in the tree structure, and the deep monitoring may monitor the tree structure comprehensively, so as to avoid missing information, thereby improving accuracy of digital scroll processing.
S13, in response to a change in the state of the target attribute being monitored, triggering a data processing function and comparing the new value of the target attribute with the old value.
Any attribute whose state changes is referred to as a target attribute. The states may include: the value of the attribute, the attribute tag of the attribute.
When monitoring that the attribute value in the tree structure changes, responding to the change of the attribute value, acquiring a new attribute value, namely a new value, and triggering a data processing function to compare the new value with an old value.
In some embodiments, the triggering a data processing function and comparing the new value of the target attribute to the old value comprises:
acquiring a new value of the target attribute and a first storage parameter of the new value;
acquiring an old value of the target attribute and a second storage parameter of the old value;
determining a first digit corresponding to the first storage parameter and determining a second digit corresponding to the second storage parameter;
triggering the data processing function to perform a comparison of the new value and the old value based on the first number of bits and the second number of bits.
For example, the number of bits of a value may be determined based on a stored parameter of the value. For example, the data processing function determines the number of bits of the new value according to the storage parameter of the new value, determines the number of bits of the old value according to the storage parameter of the old value, and compares the number of bits of the new value with the number of bits of the old value to obtain a comparison result.
Wherein, the result obtained by comparison comprises: the first number of bits is greater than the second number of bits, the first number of bits is equal to the first number of bits or the first number of bits is less than the second number of bits.
And S14, generating a target array according to the result obtained by comparison.
And processing the new value and the old value according to the result obtained by the comparison to obtain a target array, wherein the target array is used for rendering the descriptive text.
In some embodiments, the generating the target array according to the result of the comparison includes:
when the result obtained by comparison shows that the first digit is greater than the second digit, calculating the digit difference between the first digit and the second digit; performing bit complement processing on the old value according to the bit number difference; generating an old value array according to the old value after bit complementing processing;
when the result obtained by comparison shows that the first digit is smaller than the second digit, intercepting the old value according to the first digit; generating an old value array according to the intercepted old value;
carrying out data conversion on the new value to obtain a new value array;
and carrying out data splicing on the old value array and the new value array to obtain a target array.
For example, when it is determined that the new value has a greater number of bits than the old value according to the comparison result, that is, the first number of bits is greater than the second number of bits, a bit complementing operation is performed on the old value according to a bit number difference, for example, when the bit number difference is 1, a preset arabic number, such as 0, is added to the leftmost of the old value, and the old value array is obtained according to the old value after the bit complementing operation. For example, if the new value is 1000 and the old value is 100, then the bit-complemented old value is 0100, resulting in an array of [0, 1, 0, 0] old values.
For example, when it is determined that the new value has a bit number smaller than the old value according to the comparison result, that is, the first bit number is smaller than the second bit number, the old value is intercepted according to the bit number of the new value, for example, when the new value has a bit number of 3, the old value is intercepted by 3 bits from the rightmost side of the old value as the processed old value, and the old value array is obtained according to the processed old value. For example, if the new value is 100 and the old value is 1000, then the old value after the process is truncated to 000, resulting in an array of old values of [0, 0, 0 ].
For example, when the comparison result determines that the new value has a bit number equal to the old value, that is, the first bit number is equal to the second bit number, the old value is directly converted into an array form without processing the old value, and an old value array is generated.
Illustratively, the new value is converted to an array form, such as a new value of 1000, resulting in a new value array of [1, 0, 0, 0 ].
In this optional embodiment, the old value is processed according to the result obtained by the comparison to obtain an old value array; the old value is processed according to the result obtained by comparison, so that the new value and the old value are unified in format, the target array is obtained based on the generated old value array and the generated new value array, the error rate in rendering is reduced when the page to be rolled is rendered according to the target array, and the processing efficiency of digital rolling is improved.
For example, a value may be selected from the old value array and the new value array as a target array according to a preset selection rule.
By splicing the data in the old value array and the data in the new value array, data information can be effectively fused, so that the information content contained in the target array is more comprehensive, the rendering success rate is favorably improved, and the processing efficiency of digital scrolling is improved.
In some embodiments, after obtaining the target array according to the result of the comparison, the method further includes:
judging whether the target array is larger than a preset length threshold value or not;
and when the target array is larger than the preset length threshold, carrying out partition marking processing on the target array according to a preset sliding step length to obtain a partition marked target array.
For example, the preset length threshold is 3, the target array is [1, 0, 0, 0, 0, 0], the target array is greater than the preset length threshold, the target array is subjected to partition marking processing according to a preset sliding step length, the sliding step length may be the same as the preset length threshold and is 3, and certainly, the user-defined setting may also be performed according to the user's requirement. For example, a thousand-bit separator may be added to the target array as a partition marker for the target array.
By marking the target array exceeding the preset length threshold in a partitioning manner, the situation that the interrupted position information in the target array cannot be quickly found out when the rendering process is interrupted accidentally due to the overlong target array can be avoided.

analyzing a cascading style sheet corresponding to the descriptive text to construct a cascading tree;
generating a rendering tree according to the tree structure corresponding to the laminated tree and the descriptive text;
and triggering a rendering page function to render the rendering tree according to the target array to obtain a target page.
Illustratively, the cascading style sheet includes a CSS, the cascading tree includes a CSS tree, when the CSS is obtained, a node (Token) in the CSS is read, and the CSS tree is constructed according to the node, where the CSS may be an ID or a class.
The descriptive text is rendered by constructing the rendering tree, so that the efficiency of traversing the descriptive text can be improved, and the rendering efficiency of the descriptive text is accelerated.
And S16, calling a loop to traverse the rendering style and displaying the target page in a rolling way.
Illustratively, the rendered descriptive text may be scroll-exposed using a loop traversal rendering style of SASS, such as using the for-loop syntax in SASS. The cycle traversal rendering style of the SASS can reduce the writing quantity of codes in the data scroll processing and accelerate the data scroll processing speed.
In an optional embodiment, the invoking of the loop traversal rendering style to scroll-display the target page includes:
judging whether the digit of the new value is larger than a preset digit threshold value;
when the digit of the new value is larger than the preset digit threshold value, the new value array corresponding to the new value is divided to obtain a plurality of new value sub-arrays;
calling a cyclic traversal rendering style to traverse each new value element in each new value sub-array;
determining content tag elements in the target page having the same number of bits as each of the new value subarrays;
splicing each content label element, and writing the spliced content label elements into the descriptive text;
and using a dom element example to perform scrolling display on the target page according to the descriptive text.

For example, the preset length threshold is 3, the new value is 10000, the number of bits is 5 greater than the preset length threshold 1, and the new value array corresponding to the new value is divided to obtain two new value sub-arrays [1, 0, 0], [0, 0 ].

The attribute monitoring module 202 is configured to traverse the tree structure layer by layer, and monitor a plurality of attributes corresponding to the traversed layer in the tree structure.
Illustratively, the attribute values in the tree structure may be monitored by means of event (watch) monitoring, for example, the attribute values in the tree structure may be monitored by means of deep (deep) monitoring in event monitoring, that is, the tree structure is traversed hierarchically, and monitoring is added to each attribute in the tree structure, and the deep monitoring may monitor the tree structure comprehensively, so as to avoid missing information, thereby improving accuracy of digital scroll processing.
And the attribute comparison module 203 is used for responding to the monitored state change of the target attribute, triggering a data processing function and comparing the new value of the target attribute with the old value.
Any attribute whose state changes is referred to as a target attribute. The states may include: the value of the attribute, the attribute tag of the attribute.
When monitoring that the attribute value in the tree structure changes, responding to the change of the attribute value, acquiring a new attribute value, namely a new value, and triggering a data processing function to compare the new value with an old value.
In some embodiments, the attribute comparison module 203 triggers a data processing function and comparing the new value of the target attribute to the old value comprises:
acquiring a new value of the target attribute and a first storage parameter of the new value;
acquiring an old value of the target attribute and a second storage parameter of the old value;
determining a first digit corresponding to the first storage parameter and determining a second digit corresponding to the second storage parameter;
triggering the data processing function to perform a comparison of the new value and the old value based on the first number of bits and the second number of bits.
For example, the number of bits of a value may be determined based on a stored parameter of the value. For example, the data processing function determines the number of bits of the new value according to the storage parameter of the new value, determines the number of bits of the old value according to the storage parameter of the old value, and compares the number of bits of the new value with the number of bits of the old value to obtain a comparison result.
Wherein, the result obtained by comparison comprises: the first number of bits is greater than the second number of bits, the first number of bits is equal to the first number of bits or the first number of bits is less than the second number of bits.
And an array generating module 204, configured to generate a target array according to the result obtained by the comparison.
And processing the new value and the old value according to the result obtained by the comparison to obtain a target array, wherein the target array is used for rendering the descriptive text.
In some embodiments, the generating the target array by the array generating module 204 according to the comparison result includes:
when the result obtained by comparison shows that the first digit is greater than the second digit, calculating the digit difference between the first digit and the second digit; performing bit complement processing on the old value according to the bit number difference; generating an old value array according to the old value after bit complementing processing;
when the result obtained by comparison shows that the first digit is smaller than the second digit, intercepting the old value according to the first digit; generating an old value array according to the intercepted old value;
carrying out data conversion on the new value to obtain a new value array;
and carrying out data splicing on the old value array and the new value array to obtain a target array.
For example, when it is determined that the new value has a greater number of bits than the old value according to the comparison result, that is, the first number of bits is greater than the second number of bits, a bit complementing operation is performed on the old value according to a bit number difference, for example, when the bit number difference is 1, a preset arabic number, such as 0, is added to the leftmost of the old value, and the old value array is obtained according to the old value after the bit complementing operation. For example, if the new value is 1000 and the old value is 100, then the bit-complemented old value is 0100, resulting in an array of [0, 1, 0, 0] old values.
For example, when it is determined that the new value has a bit number smaller than the old value according to the comparison result, that is, the first bit number is smaller than the second bit number, the old value is intercepted according to the bit number of the new value, for example, when the new value has a bit number of 3, the old value is intercepted by 3 bits from the rightmost side of the old value as the processed old value, and the old value array is obtained according to the processed old value. For example, if the new value is 100 and the old value is 1000, then the old value after the process is truncated to 000, resulting in an array of old values of [0, 0, 0 ].
For example, when the comparison result determines that the new value has a bit number equal to the old value, that is, the first bit number is equal to the second bit number, the old value is directly converted into an array form without processing the old value, and an old value array is generated.
Illustratively, the new value is converted to an array form, such as a new value of 1000, resulting in a new value array of [1, 0, 0, 0 ]. In this optional embodiment, the old value is processed according to the result obtained by the comparison to obtain an old value array; the old value is processed according to the result obtained by comparison, so that the new value and the old value are unified in format, the target array is obtained based on the generated old value array and the generated new value array, the error rate in rendering is reduced when the page to be rolled is rendered according to the target array, and the processing efficiency of digital rolling is improved.
For example, a value may be selected from the old value array and the new value array as a target array according to a preset selection rule.
By splicing the data in the old value array and the data in the new value array, data information can be effectively fused, so that the information content contained in the target array is more comprehensive, the rendering success rate is favorably improved, and the processing efficiency of digital scrolling is improved.
In some embodiments, after the array generating module 204 obtains the target array according to the result of the comparison, the array generating module 204 is further configured to:
judging whether the target array is larger than a preset length threshold value or not;
and when the target array is larger than the preset length threshold, carrying out partition marking processing on the target array according to a preset sliding step length to obtain a partition marked target array.
For example, the preset length threshold is 3, the target array is [1, 0, 0, 0, 0, 0], the target array is greater than the preset length threshold, the target array is subjected to partition marking processing according to a preset sliding step length, the sliding step length may be the same as the preset length threshold and is 3, and certainly, the user-defined setting may also be performed according to the user's requirement. For example, a thousand-bit separator may be added to the target array as a partition marker for the target array.
By marking the target array exceeding the preset length threshold in a partitioning manner, the situation that the interrupted position information in the target array cannot be quickly found out when the rendering process is interrupted accidentally due to the overlong target array can be avoided.

The descriptive text is rendered by constructing the rendering tree, so that the efficiency of traversing the descriptive text can be improved, and the rendering efficiency of the descriptive text is accelerated.
And the page display module 206 is used for calling a loop traversal rendering style and performing scroll display on the target page. Illustratively, the rendered descriptive text may be scroll-exposed using a loop traversal rendering style of SASS, such as using the for-loop syntax in SASS.
