Wes Paranoid (IV) Mad Scientist From: Inside THE BOX Insane since: May 2000	posted 09-24-2001 20:45 So, I'm using a very simple function to change the background image of a particular table cell for one particular page on my site. The table cell uses the ID "contentCell" and I use an onLoad event in the BODY to run a simple function (below). Naturally, it's easy to target the cell's background in IE, but I can't figure out how to target it in NN. function changeBG() { contentCell.background = "background.gif" } Can anyone help?

Changing background image on TD element will work in Opera, IE and Mozilla... Use the following code: <SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript"> <!-- ; // Written by mr.maX, http://www.max.co.yu/ function setTDbgImage(layer, src) { if (document.getElementById) { document.getElementById(layer).style.backgroundImage = "url('" + src + "')"; } else if (document.all) { document.all[layer].style.backgroundImage = "url('" + src + "')"; } } // --> </SCRIPT> <BODY ONLOAD="setTDbgImage('contentCell', 'newImage.gi')"> BTW Although your code works in IE, it is not written correctly...

Wes Paranoid (IV) Mad Scientist From: Inside THE BOX Insane since: May 2000	posted 09-25-2001 07:13 Cool, thanks, Max. I have a couple questions, though. 1. Should document.all[name] be document.all[layer]? 2. Both methods (document.getElementById and document.all) seem to work in IE (if I make the change above, that is); which is necessary for Opera and Mozilla? 3. Do I need to use both methods to replace a straight image (not a background)? Thanks again! [This message has been edited by Wes (edited 09-25-2001).]

So IE 4 supports only doc.all, IE 5 and 6 supports doc.all and getElementById. Standard compliant browsers (mozilla for instance) support only getElementById.
mr.maX Maniac (V) Mad Scientist From: Belgrade, Serbia Insane since: Sep 2000	posted 09-25-2001 19:53 Wes, yes, it should be document.all[layer] (I made small typing error). Also, you should use complete function (exactly as I wrote it), if you want to make your page work in Opera, IE and Mozilla... BTW Regarding Opera, when it's running in MSIE compatibility mode, document.all is availabe, otherwise document.getElementById() is used...

document.all is an IE construct

document.getElementById will work in mozilla I'm assuming opera as well if it's following the dom (that's where this comes from)

images in all are objects of their own. imageName.src should work at this point in all browsers.
