How to populate dropdownlist with JSON data as ajax response in jQuery

Question

I am working on a j2ee application. In my application I have a drop-down list(or Select element). I want to populate this drop-down list with JSON data as a Ajax response.

Answer 1

I use "for"

var List;
 jQuery.ajax({
    url: "/demo_trial_application/json_source",
    type: "POST",
    dataType: "json",
    async: false,
    success: function (data) {
    List = data.aaData
        $('#ch_user1').empty();
        $('#ch_user1').append('All');
        for (i in List ) {
            $('#ch_user1').append('' + List[i].text + '');
        }
    }
});
