Javascript / Jquery如何从键/值获取键

Question

I have a field called City that is a drop down. It has a key value pair.

To get the value, I can simply do the following in Jquery:

    var city = $("#city").val();

How do I get the key value though?

Answer 1

因此，您需要选定选项的文本：

$('#city').find('option:selected').text();

Answer 2

如果是选择中的选项，请尝试.text() 。
