Using -ms-filter in conjunction with JavaScript

Is there a way to incorporate the -ms-filter using JavaScript?

I attempted the following approach without success:

document.getElementById(ba[i]).style.sFilter = 
      'progid:DXImageTransform.Microsoft.Alpha(Opacity=' + value*10 + ')';

On a related note, when I tried to modify the font color of an element, this code worked for everything except IE8:

document.getElementById(ba[i]).style.color = '#B4D8FD';

Answer №1

Here is a helpful reference for you:

http://msdn.microsoft.com/en-us/library/ms532847(VS.85).aspx

To utilize -ms-filter, follow these instructions:

Keep in mind that the css filter needs to be specified either as an inline style attribute or through a class. Otherwise, the filters.item property will not be accessible.

Below is some sample code:

<style>
.macska 
{
    opacity:1;
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=100)";
    filter:alpha(opacity=100);
}
</style>

<div id="xxx" style="background-color: #CCC; filter:progid:DXImageTransform.Microsoft.Alpha(opacity=100)" class="macska">
CONTENT
</div>

<script>
o = document.getElementById('xxx');
o.filters.item("DXImageTransform.Microsoft.Alpha").opacity = 20;
</script>

Please note that the following code will not function correctly:

<style>
.macska 
{
    opacity:1;
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=100)";
    filter:alpha(opacity=100);
}
</style>

<div id="xxx" style="background-color: #CCC;>
CONTENT
</div>

<script>
o = document.getElementById('xxx');
o.filters.item("DXImageTransform.Microsoft.Alpha").opacity = 20;
</script>

Answer №2

You can experiment with the cssText attribute for styling.

document.getElementById(ba[i]).cssText = 'color:#B4D8FD; filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=' + value*10 + ');';

Answer №3

Perhaps the initial inquiry can be tackled by you

document.getElementById(ba[i]).style['-ms-filter'] = 'progid:DXImageTransform.Microsoft.Alpha(Opacity=' + value*10 + ')';

As for query number 2, experiment with the aforementioned approach.

document.getElementById(ba[i]).style['color'] = '#B4D8FD';
