RegisterStartupScript不为Firefox asp.net编写任何脚本

Question

This seems to be a weird scenario but the asp.net's RegisterStartupScript does not throw any scripts on the page for firefox. This works fine for chrome. The code is as below:

ScriptManager.RegisterStartupScript(this, GetType(), "testfunc", "<script type='text/javascript'>function testfunc(){ alert('hi123'); } testfunc(); </script>", false);

When I do "View page source" for chrome the code is seen but for firefox its nothing. Also alert gets fired for chrome but, obviously, for firefox there is no alert.

I have also tried with the last parameter in the above mentioned code ie addScriptTags as true and removing the script tag from inside but to no avail.

The following is the screenshot for your reference. The firefox version is 39.0 and that of chrome is 44.0.2, if this information matters.

Please let me know if any more information is required from my end.

Please help! Thanks in advance!

Answer 1

To register javascript to the page use ClientScriptManager.RegisterStartupScript .check the link for correct usage

use it like this

ClientScript.RegisterStartupScript(this.GetType(), "testfunc", "<script type='text/javascript'>function testfunc(){ alert('hi123'); } testfunc(); </script>", false);

or like this

this.ClientScript.RegisterStartupScript(this.GetType(), "alertscript","<script>alert('Hai');</script>");

Answer 2

I got this working by moving the related code to the prerender event of the page.

So the code looks like the following

protected void Page_PreRender(object sender, EventArgs e)
{
    ScriptManager.RegisterStartupScript(this, GetType(), "testfunc", "<script type='text/javascript'>function testfunc(){ alert('hi123'); } testfunc(); </script>", false);
}

I figured out the solution from the question here

Hope this helps others!
