Can javascript read a variable passed in a url? I can read the entire url with document.URL, but I need a specific variable.

    You can also try out this function.

    function getURLParams(paramName)
    {
    var sRegExp = "[\\?&]"+paramName+"=([^&#]*)";
    var RegExpObj = new RegExp(sRegExp);
    var sURL = window.location.href;
    var arrParamVal = RegExpObj.exec(sURL);
    if(arrParamVal == null)
    return "";
    else
    return arrParamVal[1];
    }

    Here ParamName is the URL parameter name.

    Thanks
