send this as argument of function in jquery

How can i rewrite this function as below:

    $('#TblInvoiceList td img.ImgDelete').live('click' , function () {

    });

Desired form:

$('#TblInvoiceList td img.ImgDelete').live('click' , function () {
    delete(this);        
});

delete: function(){
$(this).parent().parent().remove();
}

To set the value of this in a function use Function.call(), i.e.:

delete.call(this);

The first parameter to the call() and apply() methods set the context (i.e. the value of this) of the called function.

Alternatively, if your listener only has to call delete then write your event listener thus:

$('#TblInvoiceList td img.ImgDelete').live('click' , delete);

since there's no need for a new closure just to invoke delete.

$('#TblInvoiceList td img.ImgDelete').live('click' , delete);

var delete = function(){
    $(this).parent().parent().remove();
}

Just pass in the function directly so that this is scoped properly.
