Question

我正在尝试构建一个多聊天室应用。我正在使用路由器，所以当用户点击我的网站上的链接（到聊天室，在代码中标记）时，它会将它们路由到新模板。但是当有人点击链接时，链接URL会显示在地址栏中，但它不会呈现页面。但是，如果我直接访问该链接，它将被渲染。所以基本上我的链接不会像他们应该的那样去。此外，当我点击链接时，我在控制台中收到错误：'来自Deps recexute的异常：'（下面的完整错误代码）

这是代码，首先是html，然后是Meteor javascript。我在html和js

中评论了代码的相关部分

HTML：

<head>
  <title>testChat</title>
</head>

<body>
  <div class"row">
    {{> room}}
    {{renderPage}}
   </div>
</body>

<template name="home">
  <div class="span6">
    <h1>Welcome to Meteor Chat</h1>
    <p>Please a select a room to chat in, or create a new one</p>
  </div>
</template>

<template name="room">
    <table>
        {{#each rooms}}
        <tr>
            <td><a href="/rooms/{{_id}}">{{name}}</a></td> <!-- THIS IS THE LINK! -->
            <td>{{members}}</td>
            <td>{{last_activity}}</td>
        </tr>
        {{/each}}

         <tr>
          <td colspan="3">
            <input type="text" name="name" placeholder="Enter your chatroom name"></input>
            <button type="submit" class="btn btn-primary pull-right">
              <i class="icon-plus"></i> Create Room
            </button>
          </td>
        </tr>

    </table>
</template>

<template name="chatRoom">
<h1> You are in chat room {{id}} </h1>
</template>

Meteor Javascript：

Rooms = new Meteor.Collection('rooms');

if (Meteor.isServer && Rooms.find().count() == 0) {

  var roomsA = [
    {name: 'Meteor Talk', members: 3, last_activity: '1 minute ago', id: 0, 
      messages: [
        {author: 'Tom', text: 'Hi there Sacha!'},
        {author: 'Sacha', text: 'Hey Tom, how are you?'},
        {author: 'Tom', text: 'Good thanks!'},
      ]},
    {name: 'Meteor Development', members: 2, last_activity: '5 minutes ago', id: 1},
    {name: 'Meteor Core', members: 0, last_activity: '3 days ago', id: 2}
  ];

 for (var i = 0; i < roomsA.length; i++) {
      Rooms.insert(roomsA[i]);
  }; 
}     



if (Meteor.isClient) {

Meteor.Router.add({
  '/': 'home',
  'add': function () { return 'test'},
  '/rooms/:id': function(id) {            //THIS IS THE ROUTER CALL TO THE ROOMS LINKS
    Session.set('currentRoomId', id);
    return 'chatRoom'
  }
});


 Template.room.rooms = function () {
     return Rooms.find();
 };

 Template.chatRoom.id = function() {
        var id = Session.get('currentRoomId', id);
     return id;
 };

console.log(Rooms.find().fetch());


}

如何点击我的链接不会呈现所请求的页面，但是当我直接访问该链接时，它会被渲染？

这是我点击链接时显示的完整控制台错误：

我认为，你的代码中只有拼写错误而不是

<div class+"row"> you wanted <div class="row">

..如果你纠正这个错字，你的申请将会有效。

也许有一点我认为这是使用事件处理而不是生成链接的更好方法。

HTML https://gist.github.com/rudovjan/6199753

<td><a class="goToRoom" href="#">{{name}}</a></td>

javascript就在这里 https://gist.github.com/rudovjan/6199750

Template.room.events({
    'click .goToRoom': function(e, t){
      console.log("You clicked");
      console.log(this);
       Meteor.Router.to('/rooms/' + this.id);
     }
  })

在我的Meteor应用程序中，当我单击链接时，路由器不会呈现页面
