val() throws invalid argument in Internet Explorer 10-11

[[email protected]…]

The .val() method can throw an invalid argument exception when trying to retrieve the value in IE 11. This is really an IE bug, not a jQuery bug, but it would be nice if jQuery could work around it.

The following code doesn't work in IE 11:

var x = $('<option/>');
x.val(); // This throws an exception

The root cause is this:

var e = document.createElement('option');
e.text; // This throws an exception

For anyone looking for a workaround, if you add a value attribute, then .text won't be read, e.g.

var x = $('<option value=""/>');
x.val();

Confirmed, but only for 1.x, also reproducible for IE10 – ​http://jsfiddle.net/2avmY/

Just a quick note to say that the underlying issue in IE has been fixed and will be released with the next major release. No specific timing to share yet, but news will be released via the IE Blog or @IEDevChat.
