Check if URL variable exists

[eddy556]

How can I check wether I certain variable is available in the URL?

 

For example:

 

if ([VARIABLE exists in URL])

{

//Do this

}

Sorry for creating a new thread but I've just gone and solved this myself:

 

function isWorkArea()
{

    var strQuery;
    var arrayParm;
    var arrayValue;
    var Value1, Value2

    strQuery = location.search.substring(1);

    arrayParm = strQuery.split("&");
    
    if (arrayParm[0] != null)
    {
        arrayValue = arrayParm[0].split("=");
        Value1 = arrayValue[1];
    }
    
    if (arrayParm[1] != null)
    {
        arrayValue = arrayParm[1].split("=");
        Value2 = arrayValue[1];
    }

    
    if (Value1 == "undefined")
    {
        //Value1 does not exist
    }
    
    if (Value1 != "undefined" && Value2 == "undefined")
    {
        //Value1 exists and Value2 doesn't
    
    }

}
