"Swapping" attributes with attr

[Hanpan]

Hi, I am trying to swap two attributes around, I am trying to achieve something like this:

$(trigger).find('input').attr({value: img_id, name: $(this).attr('id')});

As you can see, I am trying to swap the value of the name attribute with the value of the id attribute. The above code does not work, as $(this) is not input field object.

Can anyone suggest a clean way in which I can do the above?

assuming $(trigger) is a valid selector, this should work:

var theValue = $(trigger).find('input').val();
$(trigger).find('input').attr('id',theValue');

attr() accepts a function as the second argument:

$(trigger).find('input').val(img_id).attr('name', function(){ return
this.id });
