为什么没有定义流星模板对象？

为什么没有定义流星模板对象？

我一直在按照教程制作一个简单的论坛,在最终得到所有代码后,它告诉我'模板未定义'

forum.html代码

<head>
  <title>Forum</title>
</head>
<body>
  {{> form}}
  {{> posts}}
</body>

<template name="posts">
  <h1>Posts</h1>
  <ul>
    {{#each posts}}
      <li>
        <h3>{{title}}</h3>
        <p>{{body}}</p>
      </li>
    {{/each}}
  </ul>
</template>


<template name="form">
  <form>
    <label>Post Title:
      <input type="text" id="title" />
    </label>
    <label>Post Body:
      <textarea id="body"></textarea>
    </label>
    <input type="submit" value="Submit" id="submit"/>
  </form>
</template>

forum.js代码:

var Posts = new Meteor.Collection('posts');
  if (Meteor.isClient) {
    Template.posts.helpers({
      Posts: function() {
        return Posts.find();
      }
    });
  }

Template.form.events = {
  'click #submit': function(event){
    event.preventDefault();
    var title = $('#title').val();
    var body = $('#body').val();
    Posts.insert({
      title: title,
      body: body
    });
    $('#title, #body').val('');
  }
};

你的代码有两个问题:

模板定义在服务器上不可用,因此您需要将Template.form定义包装在Meteor.isClient条件中,或者更好的是,使用client和server目录分隔您的代码.
正确的事件映射定义需要使用以下语法:Template.form.events({...});notTemplate.form.events={...};
