Ember JSON加载问题-加载路由时出错：未定义

Question

I have the following very simple file, but when I load it by going to the #/myitem path, in the console I get "Error while loading route: undefined". 我有以下非常简单的文件，但是当我通过转到＃/ myitem路径进行加载时，在控制台中，我收到“加载路由时出错：未定义”。 The json file contents for testdata.json are shown in a comment at the top of the file. testdata.json的json文件内容显示在文件顶部的注释中。 I have validated through fiddler that the JSON file is coming down OK. 我已经通过提琴手验证了JSON文件是否正常。 Any help would be great! 任何帮助将是巨大的！

<head>

<!--
Here is what is in testdata.json:

[
    {  letter:"A", frequency:0.01492 },
    {  letter:"B", frequency:0.08167 }
]

-->

<script type="text/x-handlebars" id="application">
    <h1>Welcome to this Demo!!</h1>
    {{outlet}}
    <h1>Bye!!</h1>
            {{#link-to "myitem"}}My Item Route{{/link-to}}
</script>

<script type="text/x-handlebars" id="myitem">
    <h2>Some Items</h2>
    <ul>
        {{#each}}
        <li>{{letter}}</li>
        {{/each}}
    </ul>
</script>

<script language="JavaScript">

App = Ember.Application.create({
});

App.Router.map(function() {
    this.route('myitem');
});

App.MyitemRoute = Ember.Route.extend({
    model: function() {
        var data = Ember.$.getJSON('testdata.json');
        return data;
    }
});

</script>

This looks to be caused by testdata.json not containing valid json. 这似乎是由于testdata.json不包含有效的json引起的。

RFC 4627 states "a name is a string" meaning names need to be in quotes, whereas in your case letter and frequency aren't quoted. RFC 4627声明“名称是一个字符串”，这意味着名称必须用引号引起来，而在您的情况下， letter和frequency都不会用引号引起来。 I've had a quick go at reproducing this locally, and fixing up the quoting appears to resolve the issue. 我很快就在本地复制了此文件，并且修正了报价似乎可以解决此问题。 Try pasting this into testdata.json: 尝试将其粘贴到testdata.json中：

[ {"letter": "hello"}, {"letter": "world"} ]
