Question

I have the following in my page.

$(document).ready(function() {
    function setTheTimeout(){
        var t=setTimeout("alertMsg()",3000);
    }
    function alertMsg(){
        alert("Hello");
    }
    setTheTimeout();
});

I am getting an error in Firebug alertMsg() is not defined?

Change

var t=setTimeout("alertMsg()",3000);

To

var t=setTimeout(alertMsg,3000);

See the setTimeout documentation from Mozilla Developer Network. Using a string is the same as using eval, and eval is bad!
