Ember.js:HtmlBars 和 Handlebars.compile 命令

Ember.js: HtmlBars and the Handlebars.compile command

我在 运行 我的应用程序时收到以下错误:

Uncaught Error: Cannot call `compile` without the template compiler loaded. Please load `ember-template-compiler.js` prior to calling `compile`.

与这段代码相关:

var CarouselView = Ember.View.extend({
    template: Ember.Handlebars.compile('{{view view.itemsView}}'),
    elementId: 'carousel',
    contentBinding: 'content',
    ...

ember.js github 上已经有一个与此问题相关的问题:https://github.com/emberjs/ember.js/issues/10265

但是我将 ember-template-compiler 添加到我的 package.json 并再次遇到相同的错误。

我做了: npm install --save-dev ember-template-compiler

这是我的 package.json devDependencies:

 "ember-cli": "0.1.10",
 "ember-cli-app-version": "0.3.0",
 "ember-cli-content-security-policy": "0.3.0",

有人对 HtmlBars 和编译命令有经验吗?

您正在尝试在客户端编译 HTMLBars 模板,但是在 package.json 中添加 ember-template-compiler 只会启用 HTMLBars 模板服务器端的预编译。

要启用客户端编译,您应该将ember-template-compiler添加到bower.json,例如(使用合适的版本)

"ember-template-compiler": "http://builds.emberjs.com/tags/v1.10.0-beta.3/ember-template-compiler.js"

然后将其包含在Brocfile.js

app.import('bower_components/ember-template-compiler/index.js');

由于 Ember.js 1.10 模板编译器是 Ember 的一部分,因此在客户端编译模板所需要做的就是在 Brocfile 中添加以下行:

app.import('bower_components/ember/ember-template-compiler.js');

对于我的观点,我刚刚为他们创建了模板文件。以您的案例为例,我将创建 app/templates/views/carousel.hbs:

{{view view.itemsView}}

那么CarouselView就变成了:

var CarouselView = Ember.View.extend({
  templateName: 'views/carousel',
  elementId: 'carousel',
  contentBinding: 'content',
  ...

这样你就不用给客户模板编译器了。应该会带来更好的性能和更小的客户端下载负载。
