Initialise on keydown?

[domchristie]

Re: #50 Could we auto-initialise the plugin on keydown rather than on DOM ready? Something like:

$(document).on('keydown.expanding', 'textarea.expanding', function() {
  var $this = $(this);
  if (!$this.expanding('initialized')) {
    $this.expanding();

    // Prevent `keydown.expanding` from firing on this textarea(?)
    $this.off('keydown.expanding'); 
  }
});

I’m no sure off would work, but this might solve issues with .expanding textareas that are inserted into the DOM. Just a thought.

Hm, something like that could probably solve the most common issue (and make the plugin just work across many more cases).

We would also need to handle the case of calling $("foo").expanding() - that's the case in #50. But maybe we could do a similar thing in that case as well?

Also, the call to off wouldn't work in this case, since it's bound on the document. But we wouldn't need to worry about preventing the event from firing again since there is a check to see if it's already initialized.

That looks like an awesome idea!
