'The "This" keyboard' examples are not working properly.

[Aleix21]

Hi!
I was reading the "The "this" Keyboard" and trying the examples there.

In the examples "A function created using Function.bind()" and "A function being attached to an object at runtime." when calling sayHello() the "this" object takes an unexpected value and therefore the value of this.myName is undefined (as opposed of the expected response)

In this first usage of the function the "this" object should be the window object and the function sayHello() should not be attached to any object. Why doesn't the function sayHello() recognize the myName variable, which has the value "the global object" in these examples?

Thank you!!

Can you provide a link to the page you're describing and paste the code snippet you have a problem with? It's hard to figure out what's going on otherwise.

Yes, sorry.

Do you understand what I mean?

Did I make a stupid comment?

@Knight21 If you have a concrete example and concrete browser & version that would behave differently, you should put that info in a ticket.

Examples here are correct, however. Issue tracker is not a place to seek support but to report bugs so please ask on Stack Overflow or on #jquery irc channel.

Agreed with @mzgol. The code in your gist is correct and working for me.

My gist code doesn't work if I place it inside $( document ).ready(function() { });

@Knight21 That explains a lot. That also explains why you should ask on Stack Overflow and not here since it's not a documentation bug but your misunderstanding of what's going on here. If you place a var declaration inside a function, it doesn't create a global variable anymore.

This is a place to report bugs and that's it. Please, ask for help in other places.
