Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the view conversion method, the view conversion apparatus, and the electronic device for form design provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The application scene is an electronic form designer and comprises a design view and a source code view. A user can design a form by dragging, inputting and the like in a source code view, can also switch to the source code view, operates different controls in the form by writing source codes, and switches the source code view to a design view after the operation is completed, so that the form corresponding to the source codes can be viewed in the design view.
FIG. 1 is a flow diagram illustrating a method for view transformation of a form design, as shown in FIG. 1, in accordance with an exemplary embodiment, the method comprising:
For example, a user designs a first form through an electronic form designer, which can be divided into two scenarios: a user designs different controls in a first form through a design view, then switches the first form from the design view to a source code view, and further edits a source code corresponding to the first form, for example, the properties (background color, calculation formula, order, data format, and the like) of a certain control in the first form may be edited. Another scenario may be that the user writes source code directly in the source code view, and sets the attributes of different controls in the first form. After the user finishes writing the source code in the source code view, the source code view of the first form needs to be switched to the design view so as to view the showing state of the first form in the design view. In the process of switching from the source code view to the design view, the hash calculation is carried out on the current source code in the source code view to obtain a first hash value.
And 102, comparing the first hash value with a second hash value of the historical source code, wherein the historical source code is the source code in the source code view when the source code view is switched to the design view last time.
For example, in the last switching process from the source code view to the design view, the hash value corresponding to the last historical source code in the source code view is obtained and stored as the second hash value. Since the hash value of a piece of data is unique, if the piece of data is changed by one byte or a plurality of bytes, the hash value corresponding to the changed data is also changed, so that whether the current source code in the source code view is changed relative to the previous historical source code can be judged by comparing the first hash value with the second hash value.
And 103, when the first hash value and the second hash value are the same, displaying the design view rendered last time.
For example, when the first hash value and the second hash value are the same, it can be determined that the current source code and the historical source code in the source code view are completely consistent, and no change is generated, so that the corresponding design view does not change, and therefore, the form does not need to be re-rendered, and the design view rendered last time can be displayed, that is, the display state corresponding to the design view before switching to the current source code view is retained, where the design view rendered last time is rendered according to the source code modified last time (which may be understood as the source code modified last time before the current time and closest to the current time). Therefore, the last modified source code may be the historical source code or the source code before the historical source code. That is, no matter how many times the source code view and the design view are switched, as long as the first hash value and the second hash value are the same when switching to the design view, the source code is unchanged, and the design view does not need to be re-rendered until the first hash value and the second hash value are different, and the design view is re-rendered.
In summary, in the process of switching from the source code view to the design view, the hash value corresponding to the current source code in the source code view is obtained, and the obtained hash value is compared with the hash value obtained in the process of switching from the source code view to the design view last time. The consumption of hardware resources caused by frequent rendering in the view conversion process can be reduced, and the view conversion speed is improved.
FIG. 2 is a flow diagram illustrating another method for view transformation of a form design, according to an example embodiment, as shown in FIG. 2, step 101 includes:
in step 1011, the space and the empty line in the current source code are removed by performing format processing on the current source code.
For example, when the user switches the first form from the design view to the source view, only format modifications are made to the source code in the source view, and no substantial modifications are made to the properties of the first form, such as: the method comprises the steps of deleting a blank space and an empty line, or adding a blank space and an empty line, and then or on the premise of not changing the meaning of the original sentence, performing line changing and other processing on the long sentence, wherein only the format of a source code is modified, the first form is not actually influenced, and a design view does not need to be rendered again correspondingly, so that the waste of hardware resources and time caused by re-rendering the first form due to the modification of the format of the source code is avoided.
FIG. 3 is a flow diagram illustrating another method for view transformation of a form design, according to an example embodiment, as shown in FIG. 3, the method further comprising:
and 104, re-rendering the design view when the first hash value is different from the second hash value.
For example, when the first hash value and the second hash value are not the same, it can be determined that the current source code is not consistent with the historical source code, that is, the current source code is changed compared with the historical source code, and therefore the form needs to be re-rendered.
FIG. 4 is a flowchart illustrating another method for view transformation of a form design, according to an example embodiment, as shown in FIG. 4, step 104 includes:
For example, a corresponding first form control tree is obtained according to the current source code, where each node in the first form control tree represents a control of the first form, for example, a root node may be represented as the first form itself (which may be regarded as the topmost control in the first form), and a control corresponding to any child node in the first form control tree belongs to a control corresponding to a parent node of the node.
Illustratively, each control of the first form has a corresponding attribute, and the hash value of each node is obtained according to the control corresponding to each node in the control tree of the first form and the corresponding attribute value of each control of the first form in the current source code. For example, the first node is any node in a control tree of the first form, the first node is determined to correspond to the first control of the first form, hash calculation is performed on the attribute value corresponding to the first control in the current source code, and the obtained hash value is used as the hash value of the first node.
And 1043, determining the control needing to be re-rendered according to the hash value of each node in the first form control tree and the hash value of each node in the second form control tree, wherein the second form control tree is the form control tree obtained according to the historical source code.
For example, in the last switching process from the source code view to the design view, the hash values of each node in the second form control tree and the second form control tree are obtained according to the historical source codes and stored, after the hash value of each node in the first form control tree is obtained, the hash value of each node in the first form control tree is compared with the hash value of each node in the second form control tree, and the control corresponding to the node with the changed hash value in the first form control tree is determined as the control to be re-rendered.
Illustratively, step 1043 may be implemented by:
firstly, comparing the hash value of each node in the first form control tree with the hash value of the corresponding node in the second form control tree to determine whether the hash value of each node in the first form control tree is changed. And secondly, acquiring nodes with changed hash values in the first form control tree as target nodes. And finally, determining the target node as a control needing to be re-rendered.
For example, taking a first node in a first form control tree and a second form control tree (it can be understood that there is a control corresponding to the first node in both a current source code edited this time and a historical source code edited last time) as an example, comparing a hash value of the first node in the first form control tree with a hash value of the first node in the second form control tree, when the hash value of the first node in the first form control tree is different from the hash value of the first node in the second form control tree, determining that the hash value of the first node changes, and taking the first node as a target node. Further, a corresponding control is determined according to the target node, and the corresponding control is used as the control needing to be re-rendered. It should be noted that the target node may be a set, which includes one or more nodes and records the position or sequence number of the target node in the first form control tree, or may identify the position or sequence number of the target node in the first form control tree by marking on the target node.
The method includes the steps that a form control tree is generated and stored according to source codes edited at this time before switching to a design view, so that hash values of all nodes of the form control tree are recorded, when switching to the design view next time, the last stored form control tree and the hash values of all nodes are used for judging which node hash values are changed, and therefore when switching to the design view, the control corresponding to the node with the changed hash values is re-rendered.
In addition, in another implementation manner, the form control tree may not be saved every time the design view is switched, and only the hash value of each node is calculated and saved, so that when the design view is switched next time, the hash value of each node saved last time is used to determine which node hash values are changed. Taking the first node as an example, when switching to the design view last time, the hash value of each node in the second form control tree generated last time may be recorded in one hash value table. Therefore, when switching to the design view this time, the current hash value of the first node may be compared with the hash value of the first node recorded in the hash value table, and when the current hash value of the first node is different from the hash value of the first node in the hash value table, it is determined that the hash value of the first node changes, and the first node is used as a target node, and similarly, it may be determined whether the hash value of each node changes.
Further, step 1043 further comprises:
and when all the child nodes of the first node belong to the target node, taking the first node as the target node, wherein the first node is any node in the first form control tree.
For example, if a control includes multiple controls, the control corresponds to a control tree of a first form, that is, a node includes multiple child nodes, taking the first node as an example, when all child nodes of the first node belong to a target node, it indicates that the controls corresponding to all child nodes under the first node need to be re-rendered, that is, the controls corresponding to the first node need to be re-rendered, so that the first node can be directly used as the target node. Further, after the first node is taken as the target node, all child nodes of the first node may be deleted from the target node. For example, when the target node is a set, all child nodes of the first node in the set are deleted, and when the target node is identified by means of the label, the labels of all child nodes of the first node are removed.
In summary, in the process of switching from the source code view to the design view, the hash value corresponding to the current source code in the source code view is obtained, and the obtained hash value is compared with the hash value obtained in the process of switching from the source code view to the design view last time. The consumption of hardware resources caused by frequent rendering in the view conversion process can be reduced, and the view conversion speed is improved.

when all child nodes of a first node belong to the target node, taking the first node as the target node, wherein the first node is any node in the first form control tree;
and determining the control needing to be re-rendered according to the position or the sequence number of the target node.
2. A view transformation apparatus for form design, the apparatus comprising:
the system comprises an acquisition module, a processing module and a display module, wherein the acquisition module is used for acquiring a first hash value of a current source code in a source code view when the source code view of a first form is switched to a design view;
a comparison module, configured to compare the first hash value with a second hash value of a historical source code, where the historical source code is a source code in the source code view when the source code view is switched to the design view last time;
the judging module is used for displaying the design view rendered last time when the first hash value and the second hash value are the same; when the first hash value and the second hash value are not the same, re-rendering the design view;
the acquisition module includes:
the processing submodule is used for removing the blank spaces and the empty lines in the current source code by carrying out format processing on the current source code;
the calculation submodule is used for carrying out hash calculation on the current source code after format processing to obtain the first hash value;
the judging module comprises:
a control tree obtaining sub-module, configured to, when the first hash value is different from the second hash value, obtain, according to the current source code, a first form control tree corresponding to the current source code, where each node of the first form control tree corresponds to one control in the first form, and a control corresponding to each node of the first form control tree belongs to a control corresponding to a parent node of the node;
a hash value obtaining sub-module, configured to obtain, according to an attribute of a control corresponding to each node of the first form control tree, a hash value of each node of the first form control tree, where the attribute includes: at least one of background color, calculation formula, sequence and data format;
the judging submodule is used for determining a control needing to be re-rendered according to the hash value of each node in the first form control tree and the hash value of each node in a second form control tree, and the second form control tree is a form control tree obtained according to the historical source code;
the judgment submodule is used for:
determining whether the hash value of each node in the first form control tree has a change by comparing the hash value of each node in the first form control tree with the hash value of the corresponding node in the second form control tree;
acquiring nodes with changed hash values in the first form control tree as target nodes;
when all child nodes of a first node belong to the target node, taking the first node as the target node, wherein the first node is any node in the first form control tree;
and determining the control needing to be re-rendered according to the position or the sequence number of the target node.
