Ember.js:如何在index.html中正确包含编译好的模板?
Ember.js: How do I include compiled templates correctly in index.html?
我是ember.js的新手。我设法使用Grunt文件预编译模板。但是，当我将它们包含在index.html中时，我看到一个空页面，没有呈现模板。我做错了什么?如果我不编译模板并直接包含在index.html中，它可以工作。
我用yeoman安装了所有的东西。IO(使用底层包grunt-ember-templates, ember, webapp scaffolding)
我的index . html。
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>My New App</title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width">
<link rel="shortcut icon" href="/favicon.ico">
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<script src="bower_components/jquery/dist/jquery.js"></script>
<script src="bower_components/handlebars/handlebars.js"></script>
<script src="bower_components/ember/ember.js"></script>
<script src="scripts/templates.js"></script>
<script src="scripts/app.js"></script>
</body>
</html>
:
App = Ember.Application.create();
App.Router.map(function() {
// put your routes here
});
App.IndexRoute = Ember.Route.extend({
model: function() {
return ['red', 'yellow', 'blue'];
}
});
模板:
编辑:application.hbs
<h2>Welcome to Ember.js</h2>
{{outlet}}
编辑:index.hbs
<ul>
{{#each item in model}}
<li>{{item}}</li>
{{/each}}
</ul>
在template .js中编译模板:
define(["ember"], function(Ember){
Ember.TEMPLATES["application"] = Ember.Handlebars.template(function anonymous(Handlebars,depth0,helpers,partials,data) {
this.compilerInfo = [4,'>= 1.0.0'];
helpers = this.merge(helpers, Ember.Handlebars.helpers); data = data || {};
var buffer = '', stack1;
data.buffer.push("<h2>Welcome to Ember.js</h2>'n'n");
stack1 = helpers._triageMustache.call(depth0, "outlet", {hash:{},hashTypes:{},hashContexts:{},contexts:[depth0],types:["ID"],data:data});
if(stack1 || stack1 === 0) { data.buffer.push(stack1); }
return buffer;
});
Ember.TEMPLATES["index"] = Ember.Handlebars.template(function anonymous(Handlebars,depth0,helpers,partials,data) {
this.compilerInfo = [4,'>= 1.0.0'];
helpers = this.merge(helpers, Ember.Handlebars.helpers); data = data || {};
var buffer = '', stack1, self=this;
function program1(depth0,data) {
var buffer = '', stack1;
data.buffer.push("'n <li>");
stack1 = helpers._triageMustache.call(depth0, "item", {hash:{},hashTypes:{},hashContexts:{},contexts:[depth0],types:["ID"],data:data});
if(stack1 || stack1 === 0) { data.buffer.push(stack1); }
data.buffer.push("</li>'n ");
return buffer;
}
data.buffer.push("'n<ul>'n ");
stack1 = helpers.each.call(depth0, "item", "in", "model", {hash:{},hashTypes:{},hashContexts:{},inverse:self.noop,fn:self.program(1, program1, data),contexts:[depth0,depth0,depth0],types:["ID","ID","ID"],data:data});
if(stack1 || stack1 === 0) { data.buffer.push(stack1); }
data.buffer.push("'n</ul>'n");
return buffer;
});
});
您没有具体说明如何编译模板。他们来自*吗?HBS文件，还是使用不同的方法?
在我看来，你试图编译你的模板。html文件作为一个单一的模板，因为它在模板本身有以下代码:
data.buffer.push("'n<script type='"text/x-handlebars'">'n
每个模板文件应该只包含模板的内容，而不是脚本标签本身。
通常，您将把每个.hbs文件放在一个单独的文件中，该文件与用于确定模板名称的文件一起使用。
我之前做过一个演示，我正在使用grunt实时编写一个应用程序。这个截屏显示了如何组织.hbs文件，而源代码显示了如何编译这些文件。这展示了我的开发过程，它是通过grunt作为构建系统构建一个完整的应用程序。

希望有帮助!
我通过从grunt-ember-templates grunt配置中删除amd:true选项来解决这个问题。老实说，我在不知道它的作用的情况下添加了它。
为了完整起见，下面是我当前的grunt文件。这个文件是由yeoman自动生成的。我只给它添加了一个grunt-ember-templates配置(在emberTemplates下定义的那些)。
截至今天，我在网上找到的所有指南都不完整或过时，这对我来说很有效。
