ajax - Knockout.js 不从动态 ajax 调用更新 View

Question

我试图让 knockout.js 在 ajax 调用后更新我的 View ，但没有成功。我不断收到以下错误。它在 app.interactive.updateBindings 处出错。 parseBindingAttribute viewModel 参数未定义。

错误:

Unable to parse binding attribute. Message:
ReferenceError: interactive is not defined;
Attribute value: template: { name: 'answerTmpl', foreach: interactive.answers }

动态 HTML:

<div id="questions">
    <div id="answers" data-bind="template: { name: 'answerTmpl', foreach: interactive.answers }">
    </div>
</div>

<script type="text/javascript">

    app.viewModel.interactive.answers(@Html.Raw(@Model.Answers.ToJson()));
    app.interactive.updateBindings(document.getElementById('answers'));

</script>
<script id="answerTmpl" type="text/html">
<div>
  <span></span>  <input type="checkbox" name="Answer" />
</div>
</script>

我的 .js 文件:

(function (app, $, undefined) {

    app.viewModel = {};
    app.interactive = {};
    app.interactive.callback = function () { };

 app.viewModel.interactive = {
        content: ko.observable('test'),
        answers: ko.observableArray()
    };

        app.interactive.init = function () {

        ko.applyBindings(app.viewModel);
    };

    app.interactive.updateBindings = function (element) {
        ko.applyBindingsToNode(element);
    };

    app.interactive.init();

})(window.app = window.app || {}, jQuery);

我可以用下面的代码修复它:

ko.applyBindingsToNode(element, null, app.viewModel);

但是现在我收到这个错误:

invalid 'in' operand jQuery.template

if (templateId in jQuery['template'])

我觉得自己像个白痴。我什至没有引用 jquery 模板脚本。
