RandomBars Transition (filter)
The RandomBars Transition reveals new content by exposing random lines of
pixels. Defined via IE's CSS filter property and applied through JavaScript, here is its basic
syntax:
Syntax:
filter :progid:DXImageTransform.Microsoft.RandomBars(attribute1=value1, attribute2=value2, etc);
Syntax (post IE8):
-ms-filter: "progid:DXImageTransform.Microsoft.RandomBars(attribute1=value1, attribute2=value2, etc)";
Note: See "Difference in syntax between pre IE8 and IE8+ browsers" for more info on the changes to the filter syntax in IE8+.
Example:
<style type="text/css">
#somediv{
width: 90%;
-ms-filter:
"progid:DXImageTransform.Microsoft.RandomBars(duration=3)";
filter
:progid:DXImageTransform.Microsoft.RandomBars(duration=3);
}
</style>
<div id="somediv">Some
DIV</div>
Syntax Via Scripting
//To define a new RandomBars filter on
an element
object.style.filter ="progid:DXImageTransform.Microsoft.RandomBars(attribute=value1,
attribute2=value2)"
To access an existing property within the RandomBars filter:
object.filters.item("DXImageTransform.Microsoft.RandomBars").Property1=value1;
//To access an existing property within the RandomBars filter via the
filters[] object
object.filters[x].Property1=value1 //where "x" is
the position of the filter within list of filters on element
Below lists the attributes/properties of the RandomBars Transition:
