Question

I’m new to creating custom object in JavaScript, so it could easily be something simple.

I have these objects:

        function jsonObj(_id,_title,_class,_icon)
        {
            this.attr = new jsonAttrObj(_id,_title,_class);
            this.data = new jsonDataObj(_title,_icon);
            this.children = new Array();
        };

        function jsonAttrObj(_id, _title, _class)
        {
            this.id = _id;
            this.title = _title;
            this.class = _class;
        };

        function jsonDataObj(_title, _icon)
        {
            this.title = _title;
            this.icon = _icon;
        };

I call it using var jsonObject = new jsonObj(id,title,class,icon); all being string vars.

They work fine in Chrome and Firefox, but not IE(8). IE has the error – Expected Identifier.

You cannot use the reserved keyword ‘class’ as any variable or property name. Funny thing here–this is one of the few places where IE is getting it right and the rest are not.
