ASP. NET back Call JS method (GO)

1. Using the Response.Write method

The code is as follows:

Response.Write ("<script type= ' Text/javascript ' >alert (" XXX ");</script>");
The flaw in this method is that you cannot invoke a custom function in the script file, only the intrinsic function can be called, and the custom function can only be written on the Response.Write function definition, such as

Response.Write ("<script type= ' Text/javascript ' >function myfun () {}</script>");

2. Using the ClientScript class

The code looks like this: add code where you want to invoke a JavaScript script function, and be sure that myfun is already defined in the script file.

Clientscript.registerstartupscript (Clientscript.gettype (), "MyScript", "<script>myfun ();</script>");

This method is more convenient than Response.Write, you can directly invoke the custom function in the script file.

3. Attributes properties for normal add controls

For the normal button is: Button1.Attributes.Add ("onclick", "myfun ();");

Only valid if added in onload or in the initialization process similar to onload. The script function is executed first, and the execution order cannot be changed.

Note that all of the above methods, the background code can not be converted to the current page of the code, such as redirect, to put the paging code in the script
