Observing events on injected elements using prototype
- by snaken
I asked a question previously, it was answered correctly in the form i asked it but realised now why it wasnt working for me.
i have this code to observe multiple select menus:
$('product_options').select('select').invoke("observe","change",optchange);
This does work - as pointed out - with static layout like this:
<html>
<head>
<title>optchange</title>
<script type="text/javascript" src="prototype.js"></script>
</head>
<body>
<div id="product_options">
<select id="o0">
<option>1</option>
<option>2</option>
</select>
<select id="o1">
<option>1</option>
<option>2</option>
</select>
<select id="o3">
<option>1</option>
<option>2</option>
</select>
</div>
<script type="text/javascript">
function optchange(e) {
alert("optchanged");
}
$('product_options').select('select').invoke("observe","change", optchange);
</script>
</body>
</html>
But in my context, making a selection in the first select menu fires of an Ajax.Updater that completely replaces the content of Select 2 - this is killing the event observer. Is there a way to fix this without having to apply a new event observer each time?
Thanks.
