java - 下面代码，jQuery获取select的值总是不正确

Question

当选择了 司机之后，后台收到的值还是0，无论怎么变化都是0

Answer 1

Just $('#type').val()just

Answer 2

Console the value before uploading to the background to see if there is any change.

Answer 3

What you mean is to use the value of the option you selected, and the first one will be selected by default. Have you changed the selected options?
You can get it directly

$('#type').val();

Answer 4

Thanks for the invitation
$('#type').val()

Answer 5

I typed it exactly according to your code, and the local test did not show the bug in the question

It is recommended that the subject check whether other operations have changed the value of type.
