I expected the code below to alert "0" and "1", but it alert "2" twice. I don't the reason. Don't know if it is a problem of jQuery. Also, please help me to edit title and tags of this post if they are inaccurate.

$(function() {
for (var i=0; i<2; i++) {
$.get('http://www.google.com/', function() {
alert(i);
});
}
});
