Titanium Javascript: "that." Does Not Work

Neither this nor that works. Does anyone know what is going on?? Edit: qwerty is simply called as 'qwerty();' when in other pieces of code. It is supposed to be indepedent. Edit: I

Solution 1:

Any JS problem relating to this is likely due to the way the function using this is called. Storing a reference to this in your that variable should let you reference it from within your nested functions, exactly the way you are doing it already - assuming that qwerty() is called in a way that sets this to the correct object in the first place. (Personally I like to call such a variable self since it more accurately reflects what the variable is doing.)

However, in your function you say you get the error on this line:

that.chara[i].width

Given that you say this.chara[i].addEventListener(...) I'm guessing that the chara[i] variable holds a reference to a DOM element. If that is the case I'm guessing it is an element type that doesn't have a width property. Try this:

that.chara[i].style.width

That's the best I can do for you without more information about what error you're getting and how the qwerty() function is called...
