How to call a JavaScript function from C# code

I need to call a jav开发者_如何学编程ascript function from C# code after page Load, or is it there any way that I can do this on .aspx page itself??

Thanks

try with RegisterStartupScript

E.g:

 RegisterStartupScript("Msg1", "<script language='javascript'> alert('Hello World')  </script>");

You can use this,

Page.ClientScript.RegisterStartupScript(Page.GetType(), "script", 
   "urfunction()", true);

---

string script = "..." // your script here without <script> tags
ClientScript.ClientScript.RegisterStartupScript(GetType(), "key", script, true) 

Also if you want to use it directly from the .aspx you can use jquery

$(document).ready( function() {
    //... your script here
});
