使用Rails在视图中打印有效的，非转义的JSON [英] Print valid, non-escaped JSON in a view with Rails

问题描述

我已经尝试了一切。帮助者的每个组合原始， html_safe to_json 包括一些尝试使用 :: JSON.encode 和 CGI.unescape 。问题在于，无论我做什么，我都无法在视图中打印格式良好的JSON。它始终是HTML转义。

I've tried everything. Every combination of the helpers raw, html_safe to_json including some attempts with ::JSON.encode and CGI.unescape. The issue is that regardless of what I do, I can't print well-formed JSON in a view. It's always HTML escaped.

以下是我视图中的代码：

Here's the code in my view:

var campaignData< ;％==+（raw @ campaign.to_json）如果@campaign％> ;;

在我的情况下，它始终是引号被转义为。我会在引号上做一个gsub，但这对于IMO应该是一个非常简单，记录良好的用例来说是一个可怕的解决方案。

In my case, it's always the quotes that are escaped as ". I would just do a gsub on the quotes, but that is a terrible solution to what IMO ought to be a very simple, well documented use case.

推荐答案

这里的问题是=字符串。由于它被认为是不安全的，它会污染另一个字符串。

The problem here is with the "=" string. As it's considered unsafe, it taints the other string.

你可以做任何一个：

raw("=" + @campaign.to_json)

或

"= #{@campaign.to_json}".html_safe

大致相同。
