How can I get a value that's updated from inside an event handler ?

For example, I have the following in which I want the coordinates to be returned from the handler:

var mx, my;

function handler(evt){

mx = evt.pageX; my = evt.pageY;

console.log(mx, my); // works good

// Say I want to return x coordinate

return mx;

}

var retMX = $("div.test1").mouseleave(handler); // this doesn't happen, how can I make something of this sort?

You can't return anything from a function that hasn't been called yet. You get mx and my inside the handler and that's all.

Put more code inside the handler.

Could you suggest how I can do it ?

Put more code inside the handler.

And don’t try to put anything outside it! You can’t return anything,
