Page. ClientScript. RegisterStartupScript is not executed. page. clientscript

C # Use Page. ClientScript. RegisterStartupScript in the background to register a script prompt at the front-end. If it finds no effect, search for it and finally find the cause from du Niang:

This Page uses Page. ClientScript. RegisterStartupScript (Type type, string key, string script) multiple times)

The problem lies in the parameter key. The same Page executes the Page in order. clientScript. registerStartupScript (Type type, string key, string script). If the key is null or the same value, only the first script is executed, and the subsequent script becomes invalid.

Page. ClientScript. RegisterStartupScript (this. GetType (), "alertsuccess", "<script language = 'javascript '> SendSuccess (); </script> ");
