Handlebars.js的双花括号和三花括号之间有什么区别

Question

例如，您可以看到{{{body}}}，在模板中，您可以执行{{data.page.hero.text}}

之类的操作

我们应该注意哪些重大差异？

Answer 1

Handlebars HTML-escapes {{expression}}返回的值。如果您不希望Handlebars转义值，请使用＆＃34; triple-stash＆＃34;，{{{。

参考：http://handlebarsjs.com/#html-escaping

Answer 2

Depending on your use case and logic, you may add an option "noEscape" set to true when compiling the template if you want to use {{ }} when {{{ }}} are required to successfully replace the templates. For example: replacing with JSON values.

From the documentation:

var template = Handlebars.compile('{{foo}}', { noEscape: true });

noEscape: Set to true to not HTML escape any content.
