Question

<script type="text/javascript">
var f = function() {
    this.x = '1';
    alert(this.s); // undefined
}
f.s = '2';
f();
alert(f.s); // the value's there
alert(f.x); // undefined
</script>

I seem able to keep properties in an object instantiated with a function but I can’t access them from the function, nor can I access function variables from the outside either… is there some special trick to pierce the veil?

Answer 1

this refers to the context in which the function was called, not the function itself.
You’re looking for arguments.callee, which refers to the currently executing function.
