我根据您的情况撰写了自己的文章，它是一个快速的模型，因此可能会有错误

I wrote my own based on yours, its a quick mock up so it can have bugs

http://jsfiddle.net/N9uwx/

ko.bindingHandlers.slider = {
    init: function (element, valueAccessor, allBindingsAccessor) {
        var options = allBindingsAccessor().sliderOptions || {};
        var observable = valueAccessor();

        if(observable().splice) {
            options.range = true;        
        }        

        options.slide = function(e, ui) {
            observable(ui.values ? ui.values : ui.value);
        };

        ko.utils.domNodeDisposal.addDisposeCallback(element, function () {
            $(element).slider("destroy");
        });

        $(element).slider(options);
    },
    update: function (element, valueAccessor) {
        var value = ko.utils.unwrapObservable(valueAccessor());
        $(element).slider(value.slice ? "values" : "value", value);

    }
};
