How can I pass a parameter to a setTimeout() callback?

I have some JavaScript code that looks like:

function statechangedPostQuestion()
{
  //alert("statechangedPostQuestion");
  if (xmlhttp.readyState==         


        

Answer 1

this works in all browsers (IE is an oddball)

setTimeout( (function(x) {
return function() {
        postinsql(x);
    };
})(topicId) , 4000);
