How do I return a specific attribute of a variable using d3?

For example, I want to select an element by mouseover, and pass on the selection to a function, but only if the element's id is a particular name.

Something like this?

d3.select(body).on(mouseover, function(){ 

    if (d3.select(this).attr(id) == correct) {

        enableInteraction(d3.select(this));

    }

});
