Best way to unselect a <select> in jQuery?

Use removeAttr...

$("option:selected").removeAttr("selected");

Or Prop

$("option:selected").prop("selected", false)

There are lots of answers here but unfortunately all of them are quite old and therefore rely on attr/removeAttr which is really not the way to go.

@coffeeyesplease correctly mentions that a good, cross-browser solution is to use

$("select").val([]);

Another good cross-browser solution is

// Note the use of .prop instead of .attr
$("select option").prop("selected", false);

You can see it run a self-test here. Tested on IE 7/8/9, FF 11, Chrome 19.

Simplest Method

$('select').val('')

I simply used this on the select itself and it did the trick.

I'm on jQuery 1.7.1.
