Evaluating Javascript URL Parameter
So i have posted the code but basicly i want to add a url parameter and have javascript be able to grab and read it. So this part works, i can get the parameter and write it out with
document.write("type=" + g_querystring["type"] + "<br>");
But what i want to do is run some conditional statements to do different things specifically hide the div with the id of menu if the parameter is a certain thing.
So if i have ?type=arth on my url then the menu div should be hidden
if(g_querystring["type"] == "arth")
{
var mydiv=document.getElementB yId("menu" );
mydiv.style.visibility="hi dden";
mydiv.style.display="none" ;
document.write("Yea worked");
}
The hidding the div part etc should be fine but the condition i cant get to evaluate as true or correct or in other words even if i have ?type=arth on my url the line of code if(g_querystring["type"] == "arth") doesnt seem to evaluate as true and run the options there
document.write("type=" + g_querystring["type"] + "<br>");
