two methods of calling js in the background

1. Use the Response. Write Method

The Code is as follows:
Copy codeThe Code is as follows:
Response. Write ("<script type = 'text/javascript '> alert (" XXX "); </script> ");

This method is flawed because it cannot call the custom functions in the script file and can only call internal functions. The specific call of custom functions can only be defined in Response. Write, for example
Copy codeThe Code is as follows:
Response. Write ("<script type = 'text/javascript '> function myfun () {}</script> ");

2. Use ClientScript class

The Code is as follows: add code where you want to call a javascript script function. Make sure that MyFun has been defined in the script file.
Copy codeThe Code is as follows:
ClientScript. RegisterStartupScript (ClientScript. GetType (), "myscript", "<script> MyFun (); </script> ");

This method is more convenient than Response. Write. You can directly call the UDF in the script file.

3. Add the Attributes attribute of a common control.

For common buttons: Button1.Attributes. Add ("onclick", "MyFun ();");

It can only be added in Onload or in initialization process similar to onload. In addition, the script function is executed first, and the execution sequence cannot be changed.

Note: In all the above methods, the background Code cannot convert the code of the current page, such as Redirect. You need to put the page conversion code in the script.
