接下来，将自定义HTML元素添加到窗体，并将以下脚本复制到自定义HTML 属性中。 Next, add a Custom HTML element to the form and copy the following script into the Custom HTML property.

<script>
$(function() {
$( "[name$=city]" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "http://ws.geonames.org/searchJSON",
dataType: "jsonp",
data: {
featureClass: "P",
style: "full",
maxRows: 12,
name_startsWith: request.term
},
success: function( data ) {
response( $.map( data.geonames, function( item ) {
return {
label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
value: item.name

图3：预览和检查自动填充字段
自动完成文本字段的预览和检查表明它正在工作，虽然看起来有点不漂亮。将下面的CSS添加到自定义HTML改进了自动填充文本字段的显示方式。A preview and check on the Autocomplete text field showed that it is working, although it looked a little unpleasant. Adding the following CSS to the Custom HTML improved the way the Autocomplete text field looked.
| Code Block |

<style>
.ui-autocomplete {
background:#fff;
border:#000 1px solid;
list-style:none;
padding: 5px;
width: 250px;
}
.ui-menu-item:hover{
background:#9CE9FF;
