<a href>使用simple_format时</a>转义<a href>标签</a>

Question

I have an app where I would like to display the line breaks in the content of a text_area.

I know I can accomplish this using simple_format, but for SEO reasons I would also like to disallow them from inserting links into the content.

How do I go about displaying the line breaks, and not render the <a> tags ?

Answer 1

You can combine simple_format with sanitize :

# prints <p>foo\n<br />barbaz</p>
simple_format sanitize("foo\nbar<a href='foo'>baz</a>", :tags => [])

Pass allowable tags as the :tags option (eg :tags => ["p", "em"] ).
