I have multiple forms on one page and i am submitting them via Ajaxform plugin like this

<td>  <form> form1 </form> </td>
<td>  <form> form2 </form>  </td>

var options = {
            target:        '.ajaxMessage',  
            dataType: 'json',  // pre-submit callback 
            success:     function(data, statusText, xhr, form){ myResponse(data,form)},
            context: { element: this},

            cache: false,
            delegation: true,
            type: 'POST'   }; 

            $(".rform").ajaxForm(options); 

In mY AjaxSetup , i have this

beforeSend:function(xhr, settings){

        $this = settings.context.element;       
        alert($this);

But its not working , alert says window object
