[jQuery] convert code from prototype

[jQuery] convert code from prototype


Hello
I'd like to get started with jquery and I was wondering whether
somebody could give me a little hand or point me into the right
direction.
How would I properly convert something like the following to jquery:
    var Multi = new Class ({
        options: {
            max                : -1
        },
        initialize: function(el, options) {
            this.setOptions(options);
            this.fld         = $(el);
        },
        convert: function(v) {
            return v.replace(/\\/g,'/');
        }
    });
var m = new Multi(el);
Thank you in advance for your help.
