Syntax for calling js function at onload event on web page.

[Gary Brechbill]

I use a development tool called IronSpeed. It creates a web environment with all kinds of web pages to address database interaction etc. I am trying to deal with some look-and-feel issues that apparently require me to use a javascript function to change the CssClass of a TabContainer control. The function is defined as noted below. I need to call the function at page startup, but I am not certain what syntax to use. Any advise?

Thanks in advance.

<asp:Content id="PageSection" ContentPlaceHolderID="PageContent" Runat="server">
    <a id="StartOfPageContent"></a>
	<script type="text/javascript"  language="javascript">  
	function OverrideTabContainerClass()
	{
		var TabID;
		TabID = document.getElementById("ctl00_PageContent_Table_AP_RequestTabContainer");
		TabId.CssClass="tableContainerTab";
	}
	</script>
