Knockout.js模板不起作用 [英] knockoutjs template not working

问题描述

我正在观看有关淘汰赛的视频，我不知道为什么我的代码无法正常工作.

I was following a video about knockout and I have no idea why my code is not working.

我正在使用以下js脚本:

I'm using these js scripts:

    <script src="assets/js/knockout-2.0.0.js" type="text/javascript"></script>
    <script src="assets/js/jquery-1.7.1.min.js" type="text/javascript"></script>
    <script src="assets/js/jquery.tmpl.min.js" type="text/javascript"></script>    

<h2>Friends</h2>
    <ul data-bind="template: {name: 'friendsTemplate', foreach:friends}"></ul>

    <script type="text/html" id="friendsTemplate">
        <li>${ data.name }</li>
    </script>

<script type="text/javascript">

    function friend(name) {
        return { name : ko.observable(name) };
    }

    var viewModel = {
        friends : ko.observableArray([new friend('João'), new friend('Lucas')])
    };
    ko.applyBindings(viewModel);
</script>

此代码向我返回了此信息，它显示的是正确数量的朋友，但未显示姓名.

This code returns me this, it is showing the correct amount of friends but not displaying the names.

Friends
${ data.name }
${ data.name }

我在做什么错了?

谢谢.

编辑 进行一些测试，此代码有效，因为它未使用模板，因此我的代码是正确的，问题仅出在模板上.

EDIT Making some tests and this code works because it is not using template, so my code is correct, the problem is only with template.

<script type="text/html" id="friendsTemplate">
    <li><span data-bind="text: name"></span></li>
</script>

推荐答案

在剔除js之前，您应该先引用jquery.tmpl

you should reference jquery.tmpl prior to knockoutjs

<script src="assets/js/jquery-1.7.1.min.js" type="text/javascript"></script>
<script src="assets/js/jquery.tmpl.min.js" type="text/javascript"></script>
<script src="assets/js/knockout-2.0.0.js" type="text/javascript"></script> 

并将$ {data.name}更改为$ {name}

and change ${ data.name } to ${name}
