wildteen88 Posted December 24, 2006 Share Posted December 24, 2006 You will want to add an onLoad event handler to call your JavaScript when the page is fully loaded, otherwise your JavaScript will be run before the the rest of the web page is loaded and thus you get the error messages you are getting. Example:[code]<html><head><script type="text/javascript">/* this function will be called when the page is loaded */function load(){ alert("Page is loaded");}</script></head><!-- The event handler: --><body onload="load()"><h1>Page content</h1>page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. <br /></br />page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. page content here. <br /><br />page content here. page content here. page content here. page content here. page content here. page content here. </body></html>[/code] Link to comment https://forums.phpfreaks.com/topic/31755-initialization/#findComment-147296 Share on other sites More sharing options...
Stopofeger Posted December 26, 2006 Author Share Posted December 26, 2006 Yes thats what i do.But there is sometimes when i have to do things before the document is fully loaded.So my question is, which objects can i use before the page loads?definetly not document object, its null.that leaves me with only predefined objects like Array, Date etc. Btw can i use window obj before loading?
