What I am trying to achieve (with jQuery) is this:

```
  $('#123').closest('.sender').trigger( "click" );

```

To simulate a click on a CLASS "sender" that is a class of a div with ID "123"

```
<div id="123" class="sender"></div> 

```

UPDATE: Thanks to Pranav this has been sorted. Here is the result for those who need it:
