Does anyone know why when I run this script on my page for a "TD" tag:

<br />
BackgroundImage = document.getElementById('SomeTD').style.backgroundImage;<br />
                if(BackgroundImage.toLowerCase().indexOf('.png',0) != -1){<br />
                    ImageAddress = BackgroundImage.substr(BackgroundImage.toLowerCase().indexOf('(',0) + 1, BackgroundImage.toLowerCase().indexOf(')',0) - 2);<br />
                    document.getElementById('SomeTD').style.backgroundImage = 'none';<br />
                    document.getElementById('SomeTD').style.filter = 'progid:DXImageTransform.Microsoft.AlphaImageLoader(src=\'' + ImageAddress + '\', sizingMethod=\'scale\');';<br />
                }<br />

It does the job perfectly, but it makes all the element(like button and textbox) in this table cell ("TD"), disabled and they are not click able or even the flashing cursor in textbox is not shown and you can not type in it?! OMG | :OMG:

Sojaner!

Because basically the filter creates an image of what the element looks when it's rendered with the filter effect, and shows that instead of the element.

You could try to put the background on one element and the controls in another element, and position the elements absolutely so that the controls display on top of the background element.

This is a very complex matter if you are going to do it securely.... Perhaps you should purchase a 3rd party tool.
