How can I pass global variables into a function?

Is it possible to pass variables into an onReadyStateChange function for and XMLHTTP object?

• Whenever I try to add variable parameters or even add () to the function it stops working. The code I am talking about is xmlhttp.onreadystatechange = function

• Answer:

  The reason that wouldn't work is because the value you set for xmlhttp.onreadystatechange has to be a function. If you have function() or function(arg1, arg2), it wouldn't work because the value would be the value returned by the execution of the function. Try xmlhttp.onreadystatechange = function (){ function(arg1, arg2);}
