JQuery / Ajax中的错误

Question

Hello I am trying to get a value from an HTML option tag but i'm getting the next error:

function get_states(){
    $(function(){
        $.ajax({
            **var id = $(this).val;** it says that the error is here but I don't see it
            url: 'competitors/get_states.php',
            method: 'post',
            contentType: "application/json",
            data: {id = id}
        }).done(function(msg){
            alert(msg);
        }).fail(function(msg, TxtStatus){
            alert("fallo: "+ TxtStatus);
        });     
    });
};

Hope you can help me, have a nice day.

Answer 1

var id = $(this).val;

Should be

var id = $(this).val();

.val is a property, .val() is a method

To get the value of an element from jQuery, you need to use .val()
