mostly ignorance. :D
i'm still learning all these different frameworks, how they work together, what is suited for when, etc... i wasn't even aware of this.value or $(this).val() in this particular context. i probably could have figured that out eventually, but there's just too many ways to do the same thing. :)
I agree with that, too many ways to do the same thing - ideally there'd only be one that works everywhere :)
Noob question: so where is the security here? Why stops anyone from just code inspecting and getting the password?
thanks
@thegreyspot, 'password' refers to the id of the <input>. It's not a hard-coded value.
thanks.
cool!

BTW Great Backbone tutorial!
Just curious as why you chose to use
$(e.currentTarget).val()overthis.valueor$(this).val()?i.e. is it required or just style preference?
