Why javascript function not working from content page onload?

Question

I am using ASP.NET 3.5.

I have a content page and I want to call a javascript function on this page's load event.

I tried adding:

onload="GetLocalDate();"

within the content page placeholder tag, but it is not working. But when I call this function from any button's OnClientClick event, it works.

How to make it work on Content Page's load event?

What does this "GetLocalDate()" do? Does it reference elements or just the date object? Any code block would be appreciated. — War10ck, Dec 05 '12 at 18:39

Have you tried calling from document.ready?

$(document).ready(function () {
    GetLocalDate();
}

Put that inside script tag on your page

The content page "Placeholder" tag is a server side only control. It doesn't produce any code on the client other than arranging its contents etc. As such, the JavaScript onload handle is never rendered.

Examine your browser / client-side source to verify this.

<script type="text/javascript">
function pageLoad(){
    GetLocalDate();
}
</script>

Without an explanation of your code, it's difficult for people to understand without context. – nickhar Dec 06 '12 at 02:29

$(document).ready(function () {
    GetLocalDate();
}

Should work. Since it was not working for you, I would assume that you do not have a reference to the jQuery library in your page.

If you don't want to include the jQuery library in your project for some reason, you could inject it from server-side code within your content page:

ClientScriptManager cs = Page.ClientScript; cs.RegisterStartupScript(...) <-- add necessary details here (the Type, scriptname, the text, and a Boolean to whether you need it to include its own tags)

You should also check to make sure it hasn't already been registered before using it though (IsStartupScriptRegistered).
