onClick event in a For loop

Question

I\'ve tried to create a loop with a for, and increment by an onclick event, but it doesn\'t work.

A part of js :

 var gameCase = [\'\', \'\', \'\', \

John Resig covers this topic very well in "Secrets of the JavaScript Ninja" ( http://ejohn.org/apps/learn/#59 )

You'll need to create a temporary scope to preserve i's value

for ( var i = 0; i < itemLists.length; i++ ) (function(i){ 
  itemLists[i].onclick = function() {
      // do something
  }
})(i);

Edit:

var gameCase = ['', '', '', '', '', '', '', '', ''], // 9
$listParent = $('game').find('ul'), // li's parent
itemLists = $('game').getElementsByTagName('li'); // 9 items

var listHandler = (function() {
  var i = 0;

  return function() {
    // $(this) will in here refer to the clicked li
    i++ // increment i

    if ( i === 9 ) {
      $listParent.off('click', 'li', listHandler); //remove eventhandler when i reaches 9
    }
  }
}());

$listParent.on('click', 'li', listHandler); // attach eventhandler to ul element

This should do what you want, cant test it right now since I'm at work.
