Question

试图学习流星。我浏览了Discover Meteor书，现在我正在尝试自己创建一个简单的应用程序，但我只是设置了一些基本的模板和路由。我没有显示对象的值，而是获得了[object Object]。我在另一个问题中读到，这是尝试打印对象而不是字符串的结果，但我认为使用{{temperature}}和{{outlook}}会返回值....

感觉我错过了一些基本的东西。代码如下：

的layout.html：

   <template name="layout">
    <nav class="navbar navbar-inverse navbar-fixed-top">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="#">Project name</a>
        </div>
        <div id="navbar" class="collapse navbar-collapse">
          <ul class="nav navbar-nav">
            <li class="active"><a href="#">Home</a></li>
            <li><a href="#about">About</a></li>
            <li><a href="#contact">Contact</a></li>
          </ul>
        </div><!--/.nav-collapse -->
      </div>
    </nav>

    <div id="main" class="row-fluid">
        {{yield}}
    </div>

 </template>

router.js：

    Router.configure({
    layoutTemplate: 'layout'
});

Router.map(function() {
    this.route('forecastList', {path: '/'});
});

forecast_list.html：

<template name="forecastList">
<div class="forecast-container">
    <div class="row forecasts">
        {{#each forecasts}}
            {{> forecastItem}}
        {{/each}}
    </div>
</div>
</template>

forecast_list.js：

var forecastData = [
    {
        temperature: '30',
        outlook: 'Today is forecasted to be sunny.'
    },
    {
        temperature: '75',
        outlook: 'Today is forecasted to be cloudy.'
    }
];
Template.forecastList.helpers({
    forecast: forecastData
});

forecast_item.html：

<template name="forecastItem">
    <div class="forecast">
        <div class="forecast-content">
            <h1>{{temperature}}</h1>
            <h2>{{outlook}}</h2>
        </div>
    </div>
</template>

Answer 1

Template.forecastList.helpers({
    forecasts: function(){
       return forecastData;
    }
});

Meteor app正在打印[object Object]而不是值？
