jQuery Mobile growing text area with AJAX data

Question

I am loading text to an input box via the $("textarea").val(ajaxData); however it will not autogrow, and my data is not fully displayed. Is there any method or anything that I can call to force an update?

Answer 1

There's indeed an internal function that is responsible for resizing, called resizeCheck(). However, that function is a private implementation detail and is not exposed by the widget as a public method.

You can work around this, though: since resizeCheck() is called by the widget's keyup event handler, you can trigger that event yourself after setting the new value:

$("textarea").val(ajaxData).keyup();

This will resize the widget in the exact same way as if you had typed the new text "by hand".
