The thing is - IE5.0 doesn't support .apply AT ALL! So we've created a
function to emulate it. It works fine for objects passed in as the first
argument, but I don't really understand what it means to pass a string
as the first argument - so if someone can explain, then maybe I could
fix the emulation!
Here's the current fix:
if (typeof Function.apply != 'function') {
Function.prototype.apply = function (o, a) {
var r;
if (!o) o = {};
o.___apply = this;
switch((a && a.length) || 0) {
case 0 : r = o.___apply();
break;
case 1 : r = o.___apply(a[0]);
break;
case 2 : r = o.___apply(a[0], a[1]);
break;
case 3 : r = o.___apply(a[0], a[1], a[2]);
break;
case 4 : r = o.___apply(a[0], a[1], a[2], a[3]);
break;
case 5 : r = o.___apply(a[0], a[1], a[2], a[3], a[4]);
break;
case 6 : r = o.___apply(a[0], a[1], a[2], a[3], a[4], a[5]);
break;
default : for(var i = 0, s = ""; i < a.length; i++) {
if(i != 0) s += ",";
s += "a[" + i + "]";
}
r = eval("o.___apply(" + s + ")");
}
o.__apply = null;
return r;
}
}
Cheers
