如何敲击嵌套模板

Question

我试图弄清楚为什么这个嵌套模板不会显示任何内容。我有2个类Foo / Bar，ViewModel有一个可观察的Foo数组，而Foo有一个Bar的集合

目前我所看到的只是Foo项目

即

• someitem

而不是

• someitem

  • 子项

列出项目

<ul data-bind="template: {name: 'TopTemplate' , foreach: foos}"></ul>
<script type="text/html" id="TopTemplate">
    <li data-bind='text: Name'>   
        <ul data-bind=" template: {name:  'NestedTemplate' , foreach:  bars} " style="list-style-type:circle;margin-left:15px">
        </ul>
    </li>
</script>                                                   
<script type="text/html" id="NestedTemplate">         
    <li data-bind='text: Name'>
    </li>
</script>  


    var Foo = function () {

    var self = this;
    self.Name = ko.observable('someitem');

    self.bars = ko.observableArray([new Bar()]);

    self.HasChildren = ko.observable(false);


    self.addBar = function () {
        self.bars.push(new Bar());
    };
    self.removeBar = function (param) {
        self.bars.remove(param);
    };
    self.bars.push(new Bar());

    }
    var Bar = function () {

    var self = this;
    self.Name = ko.observable('subitem');

    }

    var ViewModel = function () {

    var self = this;
    self.foos = ko.observableArray([new Foo()]);
    self.addFoo = function () {
        self.foos.push(new Foo());
      };
      self.removeFoo = function (param) {
        self.foos.remove(param);
       };

    }

    $.ajax({
    url: '@Url.Action("AddFoos")',
    type: 'GET',
    async: false,
    contentType: 'application/json',
     success: function (result) {

        ko.applyBindings(new ViewModel(result));

      }
    });
