Overriding A Function 2

[Elcid32]

Hello Fourm!

I have a question for ya. Is it possible to redefine a function in Javascript? For example:

function myTest(){

  this.showAlert = function(){
    alert('Show Me!')
  }
  this.callAlert = function(){
    this.showAlert();
  }
}
test = new myTest;
test.showAlert = function(){ alert('No! Show Me Instead')}
test.callAlert;

Thanks!

Jeff

As Jeff hints at, your above code overrides the function with no problems. You are seeing no results because you are missing 2 sets of brackets:

function myTest(){

  this.showAlert = function(){
    alert('Show Me!')
  }
  this.callAlert = function(){
    this.showAlert();
  }
}
test = new myTest[!]()[/!];
test.showAlert = function(){ alert('No! Show Me Instead')}
test.callAlert;[!]()[/!]

Hope this helps,

Oops - that last set should be before the semicolon, of course.
