JavaScript click handler not working as expected inside a for loop [duplicate]

Answer 1

$("#div" + i).click(
    function() {
        alert(i);
    }
);

It's because it's using the value of i as a closure. i is remembered through a closure which increases at every stage of the foor loop.

$("#div" + i).click(function(event) {
    alert($(event.target).attr("id").replace(/div/g, ""));
});
