Question

Javascript: Using insertAdjacentHTML and AlphaImageLoader problem

Asked by: rise4peace

Hello,

I am having trouble getting the following code to display transparent png files. This code sits in an external .js file that is loaded when the html page is loaded. If this code is placed directly into the html file it works correctly but this will not work in this case because it would mean touching well over 1,000 files. Since the .js file is already linked to these documents if I make this change once it'll affect every document which is an easier solution.

Unfortunately I have a feeling that trying to write this into the html using javascript fails because the filter 'AlphaImageLoader' doesn't get called...

Here's the code. Hopefully someone has run into this problem before and can offer a solution.

cheers,

rise4peace


div =   '<div id="cancelbtn" style="position:absolute;top:686px;left:10px;width:140;height:66; z-index: 1; filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src="../images/buttons/cancel.png");" border="0" onMouseDown="cancel();"></div>';

div2 = '<div id="menubtn" style="position:absolute;top:611px;left:10px;width:140;height:66; z-index: 1; filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src="../images/buttons/menu.png");" border="0" onMouseDown="goMenu();"></div>';

divwrite = div + div2 ;
document.body.insertAdjacentHTML("beforeEnd", divwrite);

Simple you can't do it that way because the Loader requires that executable code gets brought into memory.  That can only happen at load time when the styles are being loaded in.  After the fact modification will not bring in the code because it is not a conventional link.

You could try writing the style in the head during the load as as class and then write the divs with the class instead of a style entry.

I tried using the onLoad feature and it still didn't work.

Can you post an example of the technique you were explaining?

document.write('height:66; z-index: 1;display:none;');
document.write('filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src="../images/buttons/cancel.png");}');

COBOLdinosaur,

that works like a champ!

final question, since i have over 300+ htm files that need this added i suppose there's no other solution than to hard code all of this into each page correct? is there a way i can add all of this except the onLoad and div tags to a stylesheet??

thanks,

rise4peace
