Doesn't JavaScript support closures with local variables?
- by qollin
I am very puzzled about this code:
var closures = [];
function create() {
for (var i = 0; i < 5; i++) {
closures[i] = function() {
alert("i = " + i);
};
}
}
function run() {
for (var i = 0; i < 5; i++) {
closures[i]();
}
}
create();
run();
From my understanding it should print 0,1,2,3,4 (isn't this the concept of closures?).
Instead it prints 5,5,5,5,5.
I tried Rhino and Firefox.
Could someone explain this behavior to me?
Thx in advance.
