使用 Knockoutjs 和 jCarouselLite

Working with Knockoutjs and jCarouselLite

抱歉这么快,但我需要看一个使用 jCarouselLite 的 Knockoutjs 的工作示例(请在 jsFiddle 中)。我似乎无法让它发挥作用。这是我之前关于此的问题:

Having trouble making Knockout and jCarouselLite to work

现在,我所做的是在我的实际项目之外进行简单的尝试。这是我的代码:

HTML:

    <h2>Index</h2>

    <div id="index-root">

        <div class="house-row" data-bind="slide: true">

            <div class=" house-row-nav"><a href="javascript:void(0)" id="item-prev"></a></div>
            <div class="house-row-nav"><a href="javascript:void(0)" id="item-next"></a></div>

            <ul data-bind="foreach: images">
                <li>
                    <div class="house-row-box nopadding-left nopadding-right">
                        <div class="image-wrapper">
                            <img data-bind="attr: { src: $data.image }" alt="image"><span data-bind="text: $data.image"></span>
                        </div>
                    </div>
                </li>
            </ul>

            <div class="clearfix"></div>

        </div>

    </div>

还有 KOjs:

$(document).ready(function () {
    var model = new IndexViewModel();

    model.init();

    ko.applyBindings(model, document.getElementById("index-root"));
});

var IndexViewModel = function () {
    var self = this;

    self.images = ko.observableArray();
    //
    // Custom bindings
    //
    //ko.bindingHandlers.slide = {
    //    init: function (element) {            
    //    },
    //    update: function (element, valueAccessor) {
    //        $(element).jCarouselLite({
    //            btnNext: ".next",
    //            btnPrev: ".prev",
    //            visible: 3,
    //            speed: 1450,
    //            mouseWheel: true
    //        });
    //    }
    //};
    //
    // Methods
    //
    self.init = function () {

        self.images.push({
            image: "/Images/1.png"
        });

        self.images.push({
            image: "/Images/2.png"
        });

        self.images.push({
            image: "/Images/3.png"
        });

        self.images.push({
            image: "/Images/4.png"
        });

        self.images.push({
            image: "/Images/5.png"
        });


        //$(".house-row").jCarouselLite({
        //    btnNext: ".next",
        //    btnPrev: ".prev",
        //    visible: 3,
        //    speed: 1450,
        //    mouseWheel: true
        //});

    };
};

$(document).ready(function () {
    $(".house-row").jCarouselLite({
        btnNext: ".next",
        btnPrev: ".prev",
        visible: 3,
        speed: 1450,
        mouseWheel: true
    });
});

评论$(".house-row").jCarouselLite...ko.bindingHandlers.slide...是我尝试初始化 jCarouselLite 的位置。

jsfiddle 中的示例真的可以帮助我解决这个问题。

这是第一次尝试。我不得不将初始调用放在计时器中,因为它是在 foreach 绑定发生之前被调用的,因此轮播没有任何内容。更高级的设计可能会将 foreach 绑定作为 slide.

的一部分

设置调用位于 init 部分,因为它只发生一次。我在您之前的线程中建议了 update 部分,因为我认为需要处理轮播上的重复操作并将其选择绑定到可观察对象或其他东西。我们这里不这样做。

ko.bindingHandlers.slide = {
  init: function(element) {
    setTimeout(function() {
      $(element).jCarouselLite({
        btnNext: ".next",
        btnPrev: ".prev",
        visible: 3,
        speed: 1450,
        mouseWheel: true
      });
    }, 0);
  },
  update: function(element, valueAccessor) {}
};


$(document).ready(function() {
  var model = new IndexViewModel();

  model.init();

  ko.applyBindings(model, document.getElementById("index-root"));
});

var IndexViewModel = function() {
  var self = this;

  self.images = ko.observableArray();
  //
  // Methods
  //
  self.init = function() {

    self.images.push({
      image: "/Images/1.png"
    });

    self.images.push({
      image: "/Images/2.png"
    });

    self.images.push({
      image: "/Images/3.png"
    });

    self.images.push({
      image: "/Images/4.png"
    });

    self.images.push({
      image: "/Images/5.png"
    });

  };
