使用jQuery从PHP数组的select值获取键

Question

I'm not even sure if this is possible as I haven't been able to find anything that could help me figure out this, so I thought I'd ask.

I have a wordpress site with a user registration plugin that has a select dropdown state field with an array:

$array = array(
 'AL' => 'Alabama',
 'AK' => 'Alaska',
 'AZ' => 'Arizona',
 'AR' => 'Arkansas');

I'm trying to sync this field with woocommerce's billing_state field, which from what I can tell uses the abbreviations instead of the full name (Al, instead of Alabama).

I figured I would use the dropdown field to get the selected state and pass it along to the billing_state field by using the value attribute, but this passes along the full name, is there a way to retrieve the key instead and pass it on to the value of the input field?

Any help will be appreciated!

Answer 1

You can get the Drop down keys using jQuery .val() API.

e.g. if your drop down id is states:

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