我在控制台中收到此错误:
Assertion failed: The value that #each loops over must be an Array. You passed (generated home controller)
Uncaught TypeError: Object [object Object] has no method 'addArrayObserver'
我的 HTML 如下所示:
<script type="text/x-handlebars">
<div id="top-panel">
<h1>{{{title}}}</h1>
</div>
<div id="wrapper">
<div id="content">
{{outlet}}
</div>
</div>
</script>
<script type="text/x-handlebars" id="home">
<table>
<thead>
<tr>
<th>Id</th>
<th>Foo</th>
<th>Bar</th>
<th>Foo Bar</th>
</tr>
</thead>
<tbody>
{{#each}}
<tr>
<td>{{itemId}}</td>
<td>foo</td>
<td>foo</td>
<td>foo</td>
</tr>
{{/each}}
</tbody>
</table>
</script>
我已经这样定义了回家路线:
App.Router.map(function () {
this.resource("home", { path: "/" });
});
App.HomeRoute = Ember.Route.extend({
model: function () {
$.getJSON("mocks/items.json", function (items) {
console.log(items);
return items;
});
}
});
console.log(items) 在控制台中记录一个对象数组,这是正确的。我不知道为什么 home 模板中的每个循环都不起作用。
