jQuery选择器语句选择选择框选项标签

Question

是否有一个选择器，用于当在jQuery（'select option [@selected = ....]）之类的选择框中选择一个选项时，这很困惑，是否只是jQuery（select> option [@selected]），还有如何在jQuery选择器语句中测试一个不是第一个选项的选项

Answer 1

It would look like this (note there's no @ , this was removed in jQuery 1.3+):

jQuery("select option:selected")

If you wanted to get anything but the first, you can use :not(:first-child) , like this:

jQuery("select option:selected:not(:first-child)")
//or...
jQuery("select option:gt(0):selected")

Though to get the value, you'd typically just want to call .val() directly on the <select> , like this:

jQuery("select").val()

Answer 2

$("select option:selected");

or

$(this, "option:selected");

test not first option

$("select option:not(eq0)"); <---I think
