<pre><code>&lt;!doctype html&gt;

&lt;html lang="en"&gt;
&lt;head&gt;
  &lt;meta charset="utf-8" /&gt;
  &lt;link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" /&gt;

  &lt;link rel="stylesheet" href="/resources/demos/style.css" /&gt;
  &lt;style&gt;
  .ui-autocomplete-loading {
    background: white url('images/ajax-loader.gif') right center no-repeat;
  }
  #city { width: 25em; }
  &lt;/style&gt;
  &lt;script&gt;
  $(function() {
    function log( message ) {
      $( "&lt;div&gt;" ).text( message ).prependTo( "#log" );
      $( "#log" ).scrollTop( 0 );
    }

    $( "#city" ).autocomplete({
      source: function( request, response ) {
        $.ajax({
          url: "http://localhost/file.php",
          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
              }
            }));
          }
        });
      },
      minLength: 2,
      select: function( event, ui ) {
        log( ui.item ?
          "Selected: " + ui.item.label :
          "Nothing selected, input was " + this.value);
      },
      open: function() {
        $( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
      },
      close: function() {
        $( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
      }
    });
  });
  &lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class="ui-widget"&gt;
  &lt;label for="city"&gt;&lt;/label&gt;
  &lt;input id="city" /&gt;
&lt;/div&gt;

&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>PHP CODE for file.php</p>

<pre><code>&lt;?php echo $_GET['name_startsWith']; ?&gt;
</code></pre>

<p>Now, i want to get the data here through ajax dynamically using database. Now when i runs this code, i dont get any response &amp; the image of ajax loader continuously gets displayed.</p>

<p>How can i make it work ?</p>

<p>Thanks</p>
