Let's take a JSON example;

1. What are the benefits of using json, for example, your ** uses text, and you need to split and other processing after returning;

If you use json, you don't need it, and the return is just an object;

2. How to write the background return**, depending on the programming language, when the final result is the same, it is the standard JSON string, for example:

success": true,count":2,items": [3. How to write the front-end **, set the datatype parameter to json;

4. How to write ****, ** is the object; Such as:

success: function(data){if( == true)

in the back. datatype a;

That is, it is equivalent to int a;

Data type.

#typedef datatype int;

datatype x;

Then define each integer variable x

JSP page date pop-up box: (easyui).

Write class:class="easyui-datebox"

data: If you're using struts2, defining an FS userid global variable in the background is acceptable!
