Using .val() on select lists behaves differently in 1.9.1 than it does in 2.x

[[email protected]…]

I have a select list with multiple items in it. JQuery versions: 1.9.1 and JQuery 2.x Browsers: Firefox 22.0 and IE7-10 Operating System: Windows 7

I use $('#selectListId').val() to set the selected value to nothing. (Not my choice, but it exists throughout the code I have to support)

If I'm using version 1.9.1, my list shows as expected, nothing selected. If I'm using version 2.x, my list shows with a blank, nothing selected. My list is still there but there is a blank showing in the select box.

1.x and 2.x edge versions are consistent. 1.9.1 actually has the incorrect behaviour. If no options match when setting the value on a select element, selectedIndex should get set to -1, which means it should be blank.
