绑定前设置滑块值

Question

我正在尝试将滑块绑定为从某个值开始，就像这个 fiddle. But instead I'm getting this: fiddle 一样。我的 js 部分看起来像这样：

ko.bindingHandlers.slider = {
        init: function (element, valueAccessor, allBindingsAccessor, viewModel, bindingContext) {
             var value = valueAccessor();
       this.slider = $(element).attr("value", value());
    }
 };

 var testResult =  function (score){
                var self = this;
        self.score = ko.observable(score);
        self.id = ko.observable("slider-new");
        self.min = ko.observable(10);
        self.max = ko.observable(100); 
    };
    var result = new testResult(50);
   ko.applyBindings(result);

这应该足以强制更新：

ko.bindingHandlers.slider = {
  init: function(element) {
    $(element).trigger("change");
  },
};
