    Encoding/Decoding Escape/Unescape These scripts are intended to explain how to "hide" HTML and/or javascript from other people who view your page's source code. It is not foolproof, but it does make it more difficult to read and understand the source code. Due to the nature of how these scripts work, the explanation may seem complicated and drawn out, but be patient and it should make sense once you gain a little experience with them. You don't really have to know the ins-and-outs of these scripts, but it does help you understand how and why they work. So, take a seat and I'll do my best to make this seem as un-complicated as possible.

  • That’s what this is expected to be, anyway. It’s expected to be a reference to the current instance of whatever object it’s defined within.
  • It’ll give an error saying that this doesn’t have a member called condiments, even though it clearly does. What happened?!
  • This is because there is no binding of functions to instances in JavaScript.
  • ...3 more annotations...
  • The setTimeout function, however, just has a reference to that function. When it calls it, it’s not aware of myHotDog, so JavaScript sets this to window
  • function HotDog() { var my = this; // my references the current this, which is correct. my.condiments = "mustard, ketchup"; my.getCondiments = function() { return my.condiments; //my is guaranteed to be a reference to the original "this" } }
  • In constructors, this is always your instance. So we created a new variable, my, that references the HotDog instance. This allows you to always refer to the HotDog instance, no matter how the getCondiments function is called.

Javascript Closures - 0 views

shared by Vincent Tsao on 17 Jun 08 - Cached
  • The simple explanation of a Closure is that ECMAScript allows inner functions; function definitions and function expressions that are inside the function bodes of other functions. And that those inner functions are allowed access to all of the local variables, parameters and declared inner functions within their outer function(s).
