Setting select .val() to a value that dosen't exist as an option results in undefined in chorme only

[anonymous]

When attempting to set a select element with .val() to a value that there is no option for chrome will return undefined where as all other browsers will return the previously selected option value.

Ex: $('body').append('<select id="mySelect">' +

'<option value="1">1</option>' + '<option value="2">2</option>' +

'</select>');

console.log( $("#mySelect").val() ); $("#mySelect").val('2'); console.log( $("#mySelect").val() ); Good $("#mySelect").val('3'); console.log( $("#mySelect").val() ); Undefined in chrome - 2 in all others

I created a test case at ​http://jsfiddle.net/9T4Lq/1/.

Both Firefox (28 and 31) and Chrome 32 return null, not undefined.

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket!

Additionally, be sure to test against the "jQuery 1.x (edge)" or "jQuery 2.x (edge)" version to ensure the issue still exists—you may need to change this to a specific version depending on the test case.

For the AJAX-related tests you can create a few fiddles and submit requests to addresses with "/show/light" added to the end of the URL; example: ​http://jsfiddle.net/m_gol/3hwjC/17/show/light/

I observe null after .val(invalid) in a wide swath of browsers, including Firefox, Chrome, Opera, Safari, and IE>=6, in line with #13514 and the ​documentation: ​http://jsfiddle.net/9T4Lq/2/
