[jQuery] How to call jQuery function inside a DOM


Hi,
I am trying to call/execute a jQuery function inside of another jQuery
function, the scenario is after validation of a input text field to
check if its empty, if empty display a error message and if it has
value then execute another function, the code as below, adapted from
this link
http://yensdesign.com/2009/01/how-validate-forms-both-sides-using-php-jquery/
var name = $("#label");
var nameInfo = $("#nameInfo");
//On blur
name.blur(validateName);
//On key press
name.keyup(validateName);
$("#addPhoneExt").click(validateName);
//On Submitting
    //$("#addPhoneExt").click(function(){
        //if(validateName())
            //return true
        //else
            //return false;
    //});
    function validateName(){
        //if it's NOT valid
        if(name.val().length < 4){
            name.addClass("error");
            nameInfo.text("We want names with more than 3 letters!");
            nameInfo.addClass("error");
            return false;
        }
        //if it's valid
        else{
            $('#addPhoneExt').click(addPhoneExt);
            name.removeClass("error");
            nameInfo.text("What's your name?");
            nameInfo.removeClass("error");
            //$('#addPhoneExt').click(tb_remove);
            return true;
        }
    }
With the above code I am able to validate the input field but what I
need is to execute or call the "addPhoneExt" "tb_remove" (function to
close thickBox) function //if its valid.
Appreciate your help.
Thanks!
