[jQuery] Re: Fill key va value from response of Json { "1": "Quan 1", "2": "Quan 2", "3": "Quan 3", "4": "Quan 4" } in listbox.

var drp = document.getElementById("edit-field-city-value");
drp.options.length == 1; // Clear all existing values except first
$.each(AjaxData, function(v, k) {
drp.options[drp.options.length] = new Option(k, v);
});
