Question:
I am using the code structure below for the presentation, which is a jsp page. Usually, the web page takes more than 3 seconds to load completely.
I have injected an indicator bar (something like cvi_busy), so that some javascript enabled bar would be shown until the page loads completely. I am doing this using an iframe inside a div. And at the moment the body loads completely, I am going to hide the div and iframe.
The problem I am getting is that the indicator bar is not comming up consistently. When it loads, sometimes the indicator comes up and sometimes not. The browser I am using is IE.
<html> <body> <div id="loadImageBarDiv"> <iframe style="width:100%;height:100%;" frameborder="0" name="loadingFrame" src="jsp/Splash.html" id="loadIframe" allowTransparency="true"/> </div> //---- my presentation for the page over here. </body> <script language="javascript"> if(window.frames['loadingFrame']){ if(window.frames['loadingFrame'].xval){ window.frames['loadingFrame'].xval.remove();} window.frames['loadingFrame'].width="0px"; window.frames['loadingFrame'].height="0px"; } document.getElementById("loadImageBar").style.display="none"; </script> </html>
Solution:1
If you use jQuery, this should be real easy to fix. Just do:
<script language="javascript"> $(function() { if(window.frames['loadingFrame']){ if(window.frames['loadingFrame'].xval){ window.frames['loadingFrame'].xval.remove();} window.frames['loadingFrame'].width="0px"; window.frames['loadingFrame'].height="0px"; } document.getElementById("loadImageBar").style.display="none"; }); </script> At the start of the page. $(someFunction) is jQuery's shortcut for hooking up an event handler "onReady", which is what it sounds like you're trying to do.
