jQuery implements the method of getting json data when selecting the drop down list

This article demonstrates an example of how jQuery implements the method of getting json data when selecting a drop-down list. Share with you for your reference. The details are as follows:

function populateDropDown() {
 $.getJSON('/getData.aspx',{Name:$('#parm').val()},function(data){
  var select = $('#DDLControl');
  var options = select.attr('options');
  $('option', select).remove();
   $.each(data, function(index, array) {
   options[options.length] = new Option(array['variety']);
  });
 });
}
 
$(document).ready(function() {
 populateDropDown();
 $('#DDLchangeData').change(function() {
  populateDropDown();
 });
});

I hope this article has been helpful to your jQuery programming.
