问题描述
我正在构建一个新的Meteor应用程序，我无法弄清楚如何使用Handlebars添加JavaScript逻辑来运行 console.log（）在我的每个循环之前。在骨干我会做，<％console.log（data）; ％> 来测试数据是否被传入。
我不知道如何使用Meteor和Handlebars来做到这一点，我找不到解决方案
I'm in the process of building a new Meteor app and I can't figure out how to add JavaScript logic with Handlebars to run a console.log() before my each loop. In backbone I would just do, <% console.log(data); %> to test that the data was being passed in.
I'm not sure how to do this with Meteor and Handlebars and I couldn't find the solution on their site.
推荐答案
在您的项目中的一个客户端加载的JavaScript文件中创建Handlebars助手：
Create a Handlebars helper in one of the client-loaded JavaScript files in your project:
Template.registerHelper("log", function(something) {
console.log(something);
});
然后在您的模板中调用它：
And then call it in your template:
{{log someVariable}}
您可以登录当前上下文中只需 {{log this}} 。
You can log the current context with simply {{log this}}.
）在Meteor应用程序之外的纯手柄，用 Handlebars.registerHelper 替换 Template.registerHelper 。）
(Note that in Meteor before version 0.8, or in pure Handlebars outside of a Meteor app, replace Template.registerHelper with Handlebars.registerHelper.)
