Getter & Setter implementation for Explorer wanted.

Aug 20.2007

I know this is not a JScript forum, but I was wondering if there is a way of implementing getter/setter functionality for properties for JScript.

With JavaScript you can for example say:

[CODE]var myVar getter=function(){bla bla bla}[/CODE]

This works fine for Firefox, but IE6 and IE7 is a no go. Is there a workaround, other than using functions like getMyVar() and setMyVar()?

@DokAug 20.2007 — Getters and setters are a custom extension of firefox although I think ECMA actually endorse them. You can use the concept of closures to mimick private methods as you know them from Java or C++ but its a pretty advanced topic. My suggestion is to just avoid setters/getters all together when coding in JavaScript.

@josamotoauthorAug 20.2007 — Getters and setters are really nice if you for example want to validate a value before assigning it's value to the property. If I use a getVar() setVar(), it sadly does not hide the variable it sets.

I suppose it is the only alternative though. Thanks for your reply. ?

@DokAug 20.2007 — The only way to truly hide variables is to use closures.

Have a look at the watch method of FF and the onpropertychange of IE. You can use these events to watch for a property change in a object.

Success!
