[jQuery] Fighting a closure

[timothytoe]

I think I submitted a half-done version of this message by accident a
few minutes ago. Sorry.

This works:
  $("#port0").click(function() {bigchart(0)});
  $("#port1").click(function() {bigchart(1)});
  $("#port2").click(function() {bigchart(2)});
  $("#port3").click(function() {bigchart(3)});
  $("#port4").click(function() {bigchart(4)});

I try to roll it up like this:
  for (i=0;i<5;i++) {
    $("#port"+i).click(function() {bigchart(i)});
  }

But the closure gets me. When the function is called, i is 5 for any
of the buttons.
What is the elegant solution here?
