TypeError应用预编译的Handlebars模板和上下文 [英] TypeError applying precompiled Handlebars templates with a context
问题描述
请原谅这个noob问题，但我根本无法获得预编译的Handlebars模板来执行任何操作，但barf out
$ b
TypeError：'undefined'不是一个函数（评估'templateSpec.call（容器，把手，上下文，options.helpers，options.partials，options.data）'）
$ p
$ b
给定以下文件和内容： index.html ：includes 头部中的/handlebars.js/downloads\">Handlebars RC1运行时，以及正文：
< p> Hello，{{name}}< / p>
handlebars hello.handlebars编译 hello.handlebars 的结果templates.js
< body id =body>
< script src =templates.jstype =text / javascriptcharset =utf-8>< / script>
< script type =text / javascriptcharset =utf-8>
var compiledTemplate = Handlebars.templates ['hello'];
var html = compiledTemplate（{name：'World'}）;
document.getElementById（'body'）。innerHTML = html;
< / script>
< / body>
调用 compiledTemplate ）不管我做什么都会抛出这个错误 - 但是我能够获得客户端模板来编译和显示。我所见过的所有演练和教程都略过了这个，所以我必须错过一些愚蠢的东西。任何想法？
确保匹配Handlebars服务器和客户端软件包的版本。一种检查编译模板版本的方法如下：
句柄a_template_of_yours.handlebars | grepcompilerInfo
它应该输出如下内容：
$
第一个值是编译器修订版，它应该与浏览器中以下代码的输出相匹配：
Handlebars.COMPILER_REVISION
如果您使用 npm 下载您的Handlebars编译器，请指定您需要的版本。以下是 handlebars.runtime-v1.3.0.js 的示例：
npm install handlebars@1.3。 0 -g
Pardon the noob question but I simply can't get precompiled Handlebars templates to do anything but barf out
TypeError: 'undefined' is not a function (evaluating 'templateSpec.call(container, Handlebars, context, options.helpers, options.partials, options.data)')
each time I apply a context to a (precompiled) template.
Given the following files and contents:
- hello.handlebars:
<p>Hello, {{name}}</p>- templates.js: the result of compiling hello.handlebars via
handlebars hello.handlebars -f templates.jsindex.html: includes Handlebars RC1 runtime in the
headand this for the body:<body id="body"> <script src="templates.js" type="text/javascript" charset="utf-8"></script> <script type="text/javascript" charset="utf-8"> var compiledTemplate = Handlebars.templates['hello']; var html = compiledTemplate({ name: 'World' }); document.getElementById('body').innerHTML = html; </script> </body>Calling
compiledTemplate()throws that error above no matter what I do--yet I'm able to get client-side templates to compile and display just fine. All the walkthroughs and tutorials I've seen skip through this like its obvious so I must be missing something silly. Any ideas?解决方案Be sure to match the versions of the Handlebars server and client packages. A way to check the version of the compiled template is the following:
handlebars a_template_of_yours.handlebars | grep "compilerInfo"
It should output something like this:
this.compilerInfo = [4,'>= 1.0.0'];
The first value is the Compiler Revision, which should match the output of the following code on your browser:
Handlebars.COMPILER_REVISION
If you used npm to download your Handlebars compiler, specify the version which you need. Here is an example for handlebars.runtime-v1.3.0.js:
npm install handlebars@1.3.0 -g
