Grabbing a filter value via CEWP code behind

Question

I have employed a Query String Filter to parse a value and send it to a chart web part. now I would like to use this value in a CEWP to provide an explaination/clarification for the chart, but the CEWP does not allow connections.

Is there a way to grab this value from the Chart or Filter in the CEWP embeded javascript. ( Designer is not available where I work )

Answer 1

I used this code:

function GetValue(name)
{
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( unescape(window.location.href) );
    if( results == null )
        return "";
    else
        return results[1];
}
