Assigning DOM Element Actions Inside An Object?

Here's my object constuctor:

function suggest_object(result_id)
{
this.in_result_div = false;
this.search_element = document.getElementById(result_id);
}

And the execution code:

var suggest = new suggest_object(result_id);

document.getElementById(result_id).onmouseover = function(){suggest.in_result_div = true;}

It works as is, but i'd really like to be able to set the onmouseover inside of the object. Something like

function suggest_object(result_id)
{
this.in_result_div = false;

[Code]....

So how can I get the 'this' inside the onmouseover function to refer to the object?
