Getting previous id

[Thierry]

I have several images over which I can hover, each having their unique id.

When I hover over image 1 and then over image 2, I want to be able to have a variable which holds the previously hovered image (in this example, image 1)

I thought it would be simple but it seems to be more difficult.

 

function hover_country(id){
window.alert("You hovered over "+id);
window.alert("You last hovered over "+previous_id);
var previous_id = id;

 

Basicly, the second time you hover over an image, shouldn't it give me the id of the previous one?

Try this:

var previous_id = "Nothing";

function hover_country(id){
   window.alert("You hovered over: " + id);
   window.alert("You previously hovered over: " + previous_id);
   previous_id = id;
}
