Activate A Combobox From A Checkbox Using Google Closure

I have a set of check boxes with Id's user1,user2 and so on and also set of combo boxes with Id's usersel1,usersel2 and so on in a dialog. When a check box is checked (say suppose

Solution 1:

There are couple of issues.

First, the for cycle is applied only to the second line, not to the whole block.

Second, the way of creating the closure is wrong (see here). The value b2 is not propagated into the event handlers as you would think.

It would work if rewritten like this:

for (var g=0;g<userlist.length;g++) { //userlist.length give no of users
  b2 = goog.dom.getElement('usersel'+(g+1)); //gets combo box
  //listening if check box is clicked
  goog.events.listen(goog.dom.getElement('user'+(g+1)), 
    goog.events.EventType.CLICK, 
    makeEventHandler(b2)
  );
}

function makeEventHandler(element) {
  return function(e) {
    element.disabled = false;
  }
}
