Asp.net asynchronous loading and asp.net asynchronous loading

Asp.net asynchronous loading and asp.net asynchronous loading

I usually use either of the following two methods: JQ.

First,Directly request the page through AJAX: For example,

1: dataType must be in html or Text format,

2: Type: Must be a 'post' request

3: the backend Load event must determine whether it is a Post request.

The background code is as follows:

The test results are as follows:

The second method is similar to the Direct Request Method of. net MVC.

1: introduce using System. Web. Services in the background code;

2: The method must be static, and the [WebMethod] feature is attached to the method.

3: the data obtained in the callback function returned successfully in JQ must be the return name. d For example: data. d

4: In AJAX, you must specify contentType: "application/json; charset = UTF-8"

5: to pass Parameters, double quotation marks are required, for example, data: "{'pageindex':" + pageIndex + "}"

This is true for multiple formats. For example, data: "{'pageindex':" + pageIndex + ", 'pagesize':" + pagesize + "}"

The background code is as follows:

The front-end code is as follows:

The test results are as follows:
