I am suddenly getting this error from jQuery :

> 
> Error: cannot call methods on dialog prior to initialization; attempted to call method 'close'
> 
> 
> 

**Plugins**

```
 <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
 <script src="http://code.jquery.com/ui/1.9.1/jquery-ui.js"></script> 

```

**jQuery code** 

I am getting those messages in the following function:

```
$(document).ready(function() {
  if ($('#results').html().length != 0) {
    alert('has information');

    $('#dialog').dialog({
      modal: true,
      buttons: {
        Ok: function() {
          // If I use $(this).dialog($(this)).dialog('close'), the UI is displayed,
          // however I do not see the OK button and no errors 
          $(this).dialog('close');
        }
      }
    });
  } else {
    alert('has no data');
  }
});

```

**HTML**

```
<div id="dialog" title="Server Response">
  <p><span class="${icon}" style="float: left; margin: 0 7px 50px 0;"></span>
    <label id="results">${results}</label>
  </p>      
</div>
