特定的句柄 - 在传递Handlebars表达式时，可以转义单引号和双引号 [英] Handlebars specific - escape both single and double quotes when passing Handlebars expression

问题描述

HTML和句柄：

onclick='shareItem("{{name}}")'> 

如果名称中包含双引号，则无法成功传递安全转义名称。

Does not successfully pass a safely escaped name when it has double quotes in it.

onclick="shareItem('{{name}}')"> 

如果安全转义的名称中包含单引号，则无法成功传递。

Does not successfully pass a safely escaped name when it has single quotes in it.

我需要处理两种可能性 - 甚至是同一个字符串。

I need to handle both eventualities- and even in the same string.

必须定义一个JS变量并且感觉很草率将它传递给反斜杠加法器。

It feels sloppy to have to define a JS variable and pass it to a backslash adder.

使用Handlebars或Mustache有更简洁的方法吗？

Is there a cleaner way to do this with Handlebars or Moustache?

推荐答案

您需要注册一个操纵上下文的内联帮助器。在您的情况下，您需要转义单引号或双引号。

You need to register a inline helper that manipulates the context. In your case, you need to escape a single or double quote.

Handlebars.registerHelper('escape', function(variable) {
  return variable.replace(/(['"])/g, '\\$1');
});

通过注册这样的帮助，您可以将它与变量一起使用来实现您想要的效果。

By registering such helper, you can use it with a variable to achieve what you want.

{{ escape name }} # expects to escape any ' or "
