在 erb 中使用 ruby 数组作为 javascript 数组。转义引号

发布于 2024-12-06 09:04:35 字数 345 浏览 0 评论 0 原文

我在网上找到了很多这方面的东西，但它们对我不起作用。我错过了什么吗？

在我的控制器中，我

@t = ["a","b","c"]

在 erb 文件中的“回调”@t 呈现如下：

[&quot;a&quot;, &quot;b&quot;, &quot;c&quot;]

我已经完成了修改，将“替换为正确的 ' 符号。我读到 to_json 应该可以工作但它不起作用。 ["a","b","c"].to_json 结果是一样的。

i've found numerous things online for this but they dont work for me. am i missing something.

In my controller i have

@t = ["a","b","c"]

in the erb file that is 'callback' the @t renders like so:

["a", "b", "c"]

i've done hacks to replace the " to proper ' symbols. I've read that to_json should work but it doesnt. The following does not work ["a","b","c"].to_json. The results are the same.

to_json 工作正常。您遇到的是 Rails 3.x 的 XSS 保护。 Railscasts/ASCIIcasts。但要点是，您需要使用 raw< /a> 或 html_safe 方法：

在您的控制器中：

@t_json = @t.to_json.html_safe

或在您的视图中：

<%= raw @t %>

to_json is working fine. What you're running into is Rails 3.x's XSS protection. There's a good article on this at Railscasts/ASCIIcasts. The gist, though, is that you need to use the raw or html_safe methods:

In your controller:
