Is there a best-practice or common way in JavaScript to have class members as event handlers?
Consider the following simple example:
<head>
<script language="javascript" type="text/javascript">
ClickCounter = function(buttonId) {
this._clickCount = 0;
document.getElementById(buttonId).onclick = this.buttonClicked;
}
ClickCounter.prototype = {
buttonClicked: function() {
this._clickCount++;
alert('the button was clicked ' + this._clickCount + ' times');
}
}
</script>
</head>
<body>
<input type="button" id="btn1" value="Click me" />
<script language="javascript" type="text/javascript">
var btn1counter = new ClickCounter('btn1');
</script>
</body>
The event handler buttonClicked gets called, but the _clickCount member is inaccessible, or this points to some other object.
Any good tips/articles/resources about this kind of problems?
