How to use comments in Handlebar templates?
提问by Abhidev
I am using Handlebar.js as my templating engine. Now I want to comment out some of the blocks in my handlebar templates. But then I realized that Handlebar doesn't ignore the expressions inside the Handlebar comment block. Any workaround for this?
我使用 Handlebar.js 作为我的模板引擎。现在我想注释掉我车把模板中的一些块。但后来我意识到 Handlebar 不会忽略 Handlebar 注释块中的表达式。有什么解决方法吗？

Just add an exclamation mark after the opening brackets.
只需在左括号后添加感叹号即可。
Normal Expression:
正常表达：
{{expressions}}
Commented Expression:
评论表达：
{{!expressions}}

Use this way in your handlebar template file.
在您的车把模板文件中使用这种方式。
<div class="entry">
{{!-- only output author name if an author exists --}}
{{#if author}}
<h1>{{author.firstName}} {{author.lastName}}</h1>
{{/if}}
</div>
The comments will not be in the resulting output. If you'd like the comments to show up, then use HTML comments.
注释不会出现在结果输出中。如果您希望显示注释，请使用 HTML 注释。
<div class="entry">
{{! This comment will not be in the output }}
<!-- This comment will be in the output -->
</div>
