You can use .val() along with select element selector: 您可以将.val()与选择元素选择器一起使用：
When the first element in the collection is a select-multiple (ie, a select element with the multiple attribute set), it returns an array containing the value of each selected option, or null if no options are selected.
$('#example').val();
You can convert this array to CSV using .join() . 您可以使用.join()将此数组转换为CSV。
