setInterval argument problem (Internet Explorer)

[shiznit]

 
checkWin = function(x)
    {
    alert(x);    // Displays undefined
    }
 
 
 
function startScroll(e)
{
    if ( TimeOutID == null)
    {
    var x = e.clientX;
            alert(x);//displays correct X value
     TimeOutID = window.setInterval(checkWin,100,x);    
    }
}
 
 

I am having trouble with the setInterval function for Internet Explorer. When I send in the variable x through the setInterval function i keep getting undefined in the function being called.

I am assuming its some scope issue..?

The only mistake you are doing is, that you assume that setInterval provides more then 2 parameters. Yes, additional parameters are supported in some browsers, but as you can see far from all :D

The solution are closures for you. (works everywhere)

[PHP]function startScroll(e)
{
if ( TimeOutID == null)
{
var local_x = e.clientX;
var local_function= function() { alert(local_x) };
TimeOutID = window.setInterval(local_function,100);
}
}

[/PHP]

Hope that helps.
