Jquery 循环遍历敲除中的数组并绑定到HTML

我对淘汰赛不太熟悉，但现在是作为速成班来学习的。我的任务是循环这个JSON对象，并将某些节点放入div中，并给出结果。它基本上是一个视频卡显示，每种类型、信息、缩略图和标题中都会显示特定的信息位。然后，我将不得不加载一个视频播放器缩略图点击，但这是稍后。对于像我这样的新手，任何帮助都将不胜感激。只是没有定义

这是我的JSON对象。我走的方向对吗

下面是一些我试图编写的淘汰代码，但它没有定义。我知道这很愚蠢：（.只是想注销，这样我就可以开始做这个任务了

var PageViewModel = function (json) {
var self = this;
self.screens = ko.observableArray([]);
self.addSection = function (jsonobj) {
    console.log("jsonobj", jsonobj);
    self.screens.push(new my.VideoSection(jsonobj));
    console.log(self.screens());
}
for (var i = 0; i < json.screens.length; i++) {
    self.addSection(json.screens[i]);

}
};

return {
  pageViewModel: pageViewModel
}

var PageViewModel=function（json）{
var self=这个；
self.screens=ko.observearray（[]）；
self.addSection=函数（jsonobj）{
log（“jsonobj”，jsonobj）；
self.screens.push（新的my.VideoSection（jsonobj））；
console.log（self.screens（））；
}
for（var i=0；i

我的html只是开始循环

  <div data-bind="foreach: screens">
     <div class="container">

您似乎走上了正确的道路。有几件事需要注意：

• 您没有发布

  my.VideoSection

  构造函数的代码
• 您正确地循环了

  屏幕

  ，但是

  屏幕

  对象有一个

  config

  属性，该属性有一个

  视图

  数组，您也需要循环。您可以使用绑定

所以基本上，这个：

<div data-bind="foreach: screens">
    <div class="container" data-bind="with: config">
        <div class="row" data-bind="foreach: views">    
            <div class="col-md-6">
                <div class="card">

非常感谢@brother woodrow。它正在渲染，但在浏览器中奇怪地出现了此错误。未捕获引用错误：无法处理绑定“foreach:function（）{return screens}”消息：无法处理绑定“with:function（）{return config}”消息：无法处理绑定“foreach:function（）{return views}”消息：无法处理绑定“attr:function（）{return{src:thumbnail}}”消息：thumbnail没有定义，所以我现在理解了原因。JSON对象还有很多，在某种程度上循环失败了。现在我迷路了，哈哈。如果还有其他提示，我们将不胜感激，并感谢您的帮助！
