Handlers使用&符和脱字符号的模板 [英] Handlebars templates using ampersand and caret

问题描述

这两个很奇怪的是

  {{^ is_question}} {{/ is_question}} 
  

和

  {{&答案}} 
  

这些都不在Handlerbars文档中列出，也没有定义帮助器。 p>

任何人都知道他们在做什么？

<^> ^ is_question似乎与{{#if is_question}}交替使用。也许这是一些不赞同的速记符号？

模板的编译方式与我们编译其他模板的方式相同：

 template = Handlebars.compile（ItemTemplate）
  

我们的车把版本是：

  Handlebars.VERSION =1.0.0-rc.3; 
  

解决方案

我用 ^ ，但我必须查找& ：

  {{^ question}} X {{/ question}} =>逆选择，即如果（！question）X; 
 {{& answer}} =>未转义，通常为：{{{answer}}} 
  

We found some old Handlebars templates which are working fine, but include some odd usage of Handlebars.

The two strange ones are

{{^is_question}}{{/is_question}}

and

{{& answer}}

Neither of those are listed in the Handlerbars docs and there are no helpers defined.

Anyone know what they do?

The ^is_question appears to be used interchangeably with {{#if is_question}}. Maybe it is some deprecated shorthand notation?

The template is compiled the same way we compile other templates:

template = Handlebars.compile(ItemTemplate)

Our handlebars version is:

Handlebars.VERSION = "1.0.0-rc.3";

解决方案

I've used ^ relatively recently, but I had to look up &:

{{^ question}} X {{/question}} => inverse selection, i.e. if (! question ) X;
{{& answer}} => unescaped, typically: {{{answer}}}
