Answer 1

you can try to write to a response stream directly and output

Response.Write("<script type=\"text/javascript\"> your JS call</script>");

Answer 2

You can call a JavaScript function using registerStartupScript.

ASPX Page

<script type="text/javascript">

   function printOutput(arg) {            
      alert(arg);
   }

</script>

Code Behind

protected void DoSomethingButton_Click(object sender, EventArgs e)
{
   ClientScriptManager cs = Page.ClientScript;

   cs.RegisterStartupScript(typeof (Page), "PrintScript_" + UniqueID, "printOutput('My HTML Code Generated by jquery function');", true);
}

Answer 3

You need to pass into the web.cs a reference to the page. You will then have access to the page.clientscript method
