Description

A Method for Relational Query and Backfilling Page Objects Based on Web Pages

technical field

The invention relates to the application of the Internet, in particular to a webpage-based correlation query and a method for backfilling page objects.

Generally speaking, the way of expressing the web interface is to use the tool (Wizard) to allow the user to "next" and "next", enter some content on one interface, and click the "next" button to enter another. In the interface, enter some content again, repeat this process, and finally click "Finish". Using this solution, the user has no overall view and can only go step by step, and the interactivity is poor. The second method is to use a pop-up dialog box similar to the traditional GUI to query, select, and backfill an auxiliary method. This method cannot guide the user to input, and the correlation between multiple form units cannot be expressed, and the operation is inconvenient.

Another method is to display a form on the web interface, let the user fill in a large amount of data on the interface, and finally submit it uniformly, and the server-side uniformly checks to determine the rationality of the data. Using this method, the user cannot obtain relevant information when entering, and can only enter text or select a value from the drop-down box; when entering text, the accuracy of the input cannot be guaranteed, and when selecting from the drop-down box, if the amount of data is large It is very troublesome to select one from hundreds or thousands of data.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for webpage-based associated query and backfill page objects, which overcomes the disadvantages of poor interactivity, inability to ensure the accuracy of text input and cumbersome data selection in the prior art data query method.

In order to solve the technical problems, the present invention adopts the following technical solutions:

A method for webpage-based associated query and backfilling page objects, comprising the following steps:

a1 The first webpage interface accepts query parameters input by the user, and constructs query parameter objects according to the query parameters;

a2 generating a second webpage interface from the first webpage interface;

a3 The second webpage interface executes the query according to the query parameter object, and the query result is displayed on the second webpage interface;

a4 The second web page interface accepts the value selected by the user from the query result to construct a returned result object;

a5 The first webpage interface backfills the relevant page objects of the first webpage interface according to the returned result object and the backfill mapping table;

a6 The attribute value of the returned result object is displayed on the first web page interface.

A further optimization of the technical solution is that the query parameter object is transferred from the first webpage interface to the second webpage interface.

A further optimization of the technical solution is that after the returned result object returns to the first web page interface, the second web page interface is closed.

The query parameter object is set as an array, which includes a parameter field: parameter name, parameter value, and a Boolean constant indicating whether a parameter value must be present.

The returned result object includes a value field: attribute name, attribute value, and there are multiple attributes in the returned result object.

The backfill mapping table includes value fields: the form name of the first web page interface, and the return attribute name.

The symbol "#" is used to represent constant parameter values in the query parameter object.

By adopting the technical solution of the invention, the user can avoid tedious data selection when inputting data, and improve the interactivity of the interface and the accuracy of inputting associated data.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

As shown in Figure 1, the process of associated query and backfilling page objects is: the user enters some values (optional) on interface A, and executes the query function when a related object needs to be filled in. In interface A, according to the query parameter object, According to the value of each input form of interface A, generate query parameters, generate interface B, and pass the query parameters to interface B, interface B executes the query, and displays the query results on the interface. The user selects a suitable object (associated object) from interface B, interface B organizes the properties of the selected object, forms a returned result object, and returns to interface A, and at the same time, interface B is closed, and interface A is based on the returned result object and backfill Map the table, backfill the relevant form cells on interface A, and display the results to the user.

When passing the parameters on interface A to interface B, because the names of the parameters on interface A and interface B are generally not one-to-one correspondence, mapping must be performed, so the query parameter object is defined to pass the parameters on interface A To interface B, the input parameters include: the name of the query parameter on interface B, and the value of the parameter. The value of the parameter has two sources: static value and input field (form item) on interface A. At the same time, some query parameters are mandatory, while others are non-essential parameters. Therefore, the entire parameter domain includes three parts: parameter name, parameter value, must have a value or not. The parameter name is a string, and must have a value. Whether it is a Boolean value, only the parameter value is a little more complicated, and a special mark must be used to confirm whether it is a static value or a dynamic value. The static value is the value, and the dynamic value Use the name of the form item. In web forms, "#" is generally not used as the name of the form item, so "#" can be used to identify it. At the same time, there can be multiple parameters, so the parameter object is designed as an array, and the final parameter object is designed as:

var query parameter = [["parameter name", "#constant parameter value", true],

["parameter name 2", "form item name", false]...];

When the user enters an appropriate value and passes it to the query window (interface B), the processing on interface B is business-specific. The user can define different query methods, and finally the results that meet the conditions are displayed on interface B, and the user chooses a suitable value.

After the user selects an appropriate value, the system needs to generate an appropriate return object. The returned object part includes: attribute name, attribute value, and there can be multiple attributes in the returned object.

The definition of the returned object is:

var result = {"property name":"property value",

"PropertyName2": "PropertyValue2"};

The backfilling of query results involves two objects: the return value of the query object, the mapping between the form of the current interface and the attributes of the query results, and there must be a "backfill mapping table" to define the mapping between the returned attributes and the form.

The items of this map include: returning the attribute name, the form name of the current interface, and supporting the backfilling of items of multiple forms.

So the mapping is defined as:

var resultMaps={"Form Item Name": "Return Attribute Name" "Form Item Name 2": "Return Attribute Name 2"};

After the user of this function (application developer) defines the above data structures (query parameter object, return result object, and backfill mapping table), he can use Java Script to realize this function relatively easily:

Step 1: The user inputs query parameters on the first web page interface;

Step 2: Create a query parameter object on the first webpage interface;

Step 3: generating a second web interface from the first web interface;

Step 4: the first webpage interface transfers the query parameter object to the second webpage interface;

Step 5: Execute the query by the second webpage interface, and the query result is displayed on the second webpage interface;

Step 6: The user selects the desired value from the query results on the second web page interface;

Step 7: Construct and return a result object from the second webpage interface;

Step 8: The returned result object is returned to the first web interface, and the second web interface is closed;

Step 9: The first webpage interface backfills the relevant page objects of the first webpage interface according to the returned result object and the backfill mapping table;

Step 10: The attribute values of the returned result object are displayed on the first webpage interface.
