Hi, Zafar-
This is the sort of thing that's covered in the CDF Working Group's new
WICD specs. I've got an example on my site. [1]
To pass parameters to an SVG, use the <object> element with child
<param> elements. Each <param> element should have name/value pairs with
the 'name' and 'value' attributes; these will be exposed to the embedded
SVG document. The actual values are not necessarily specified, and can
be arbitrary strings, though there are a few formal parameter
name/values. An example of the HTML markup is:
<object type="image/svg+xml" data="embeddedDoc.svg">
<param name="color" value="orange" />
<param name="label" value="some text" />
</object>
The code for the script to access these parameterized values in the
embedded SVG might look like this:
var params =
document.defaultView.frameElement.getElementsByTagName('param');
for ( var i = 0, iLen = params.length; iLen > i; i++ )
{
var eachParam = params[ i ];
var name = eachParam.getAttribute( 'name' );
var value = eachParam.getAttribute( 'value' );
//do something here with the values;
}
My bank account number is... ;)
