[RESOLVED] Object Accessors ([SG]etters)

Hi All,

After searching for what feels like a lifetime, I am now seeking the opinions of anyone who has already tried this, or even better has got it working:

Javascript allows the functionality of defining proper Object accessors using the [B]Object.defineProperty[/B] method, or the [B]__defineGetter__/__defineSetter__[/B] functions. However IE8 only supports this using DOM elements.

The code I have right now…

[CODE]var myObj = {},

if (Object.defineProperty) {
try {
Object.defineProperty(myObj, ‘myProperty’, {
get : function(){},
set : function(val){}
});
} catch(e) {
//IE8
}
} else
if (myObj.__defineGetter__) {
if (getter) {myObj.__defineGetter__(‘myProperty’, function(){});}
if (setter) {myObj.__defineSetter__(‘myProperty’, function(val){});}
} else {
//IE6/7
}[/CODE]

Now this works great if I support Internet Explorer from version 9.

My other option is to use “jQuery style” accessors, where you define a function wrapper to determine if the setter or getter function needs calling by specifying an argument:

[CODE]function Property(obj, name, getter, setter)
{
obj[name] = function()
{
return (arguments.length ? setter : getter).apply(obj, arguments);
};
}[/CODE]

This would obviously work in all browsers, but doesn’t look as nice as the first when assigning or retrieving values.

Before anyone asks… I do require accessors for argument evaluation, so I cannot just do straight forward assignments, and the defineProperty method of doing it would be first prize.

Many thanks.
