我不太了解这个错误，最重要的是，我不知道该在哪里寻找解决问题的方法.
I don't really understand this error, and most importantly, I don't know where to look for to fix the problem.
这是我的JavaScript文件: -posts_list.js
Here are my JavaScript files: - posts_list.js
var postsData = [{
title: 'Introducing Telescope',
author: 'Sacha Greif',
url: 'http://sachagreif.com/introducing-telescope/'
}, {
title: 'Meteor',
author: 'Tom Coleman',
url: 'http://meteor.com/'
}, {
title: 'The Meteor Book',
author: 'Tom Coleman',
url: 'http://themeteorbook.com/'
}];
if (Meteor.isClient) {
Template.postsList.helpers({
posts: postsData
});
}
post_item.js
if (Meteor.isClient) {
Template.postItem.helpers({
domain: function(){
var a = document.createElement('a');
a.href = this.url;
return a.hostname;
}
});
}
posts.js
Posts = new Meteor.collection('posts');
这是html模板:
posts_list.html
<template name="postsLists">
<div class="posts">
{{#each posts}}
{{> postItem}}
{{/each}}
</div>
</template>
post_item.html
<template name="postItem">
<div class="post">
<div class="post-content">
<h3><a href="{{url}}">{{title}}</a><span>{{domain}}</span></h3>
</div>
</div>
</template>
我缺少明显的东西吗?这是版本兼容性问题吗?还是某个地方有错误?
Am I missing something obvious? Is this a version compatibility problem? Or is there a bug somewhere?
推荐答案
我认为您在posts.js中拼写错误:Mongo.Collection，它是大写字母C.
I think you misspell in posts.js: Mongo.Collection, it's capital C.
