Scripting Filters

mydiv.filters.item(0).enabled = true;

Another method is to specify the item's index by its name. Let's take our previous example and add a little script that will enable the DropShadow filter and disable the Engrave filter. Here is the code, followed by its result:

<DIV ID="mydiv" STYLE="width: 40%; filter:
 progid:DXImageTransform.Microsoft.engrave()
 progid:DXImageTransform.Microsoft.DropShadow(color='red',
 OffX=3, OffY=2)">
<IMAGE SRC="bicycle.gif"><FONT COLOR="blue">In this page we explain
 the basics of using filters.</FONT>
</DIV>
<SCRIPT LANGUAGE="JavaScript">
<!--
mydiv.filters.item(1).enabled = 1;
mydiv.filters.item("DXImageTransform.Microsoft.engrave").enabled = 0;
// -->
</SCRIPT>

In this page we explain the basics of using filters.

Notice that the Engrave filter is disabled in the script, and indeed the DIV element is not engraved.

Each filter supports its own properties and methods. The filter's properties are set during its definition and can be modified by a script. Let's modify the shadow color above from red to tan, inside the script:

<DIV ID="mydiv1" STYLE="width: 40%; filter:
 progid:DXImageTransform.Microsoft.engrave()
 progid:DXImageTransform.Microsoft.DropShadow(color='red',
 OffX=3, OffY=2)">
<IMAGE SRC="bicycle.gif"><FONT COLOR="blue">In this page we explain
 the basics of using filters.</FONT>
</DIV>
<SCRIPT LANGUAGE="JavaScript">
<!--
mydiv1.filters.item(1).enabled = 1;
mydiv1.filters.item("DXImageTransform.Microsoft.engrave").enabled = 0;
mydiv1.filters.item("DXImageTransform.Microsoft.dropshadow").color
 = "tan";
// -->
</SCRIPT>
