rails过滤html

strip_links(html)

Strips all link tags from text leaving just the link text.

Examples

  strip_links('<a href="http://www.rubyonrails.org">Ruby on Rails</a>')
  # => Ruby on Rails

  strip_links('Please e-mail me at <a href="mailto:[email protected]">[email protected]</a>.')
  # => Please e-mail me at [email protected].

  strip_links('Blog: <a href="http://www.myblog.com/" class="nav" target=\"_blank\">Visit</a>.')
  # => Blog: Visit
strip_tags(html)

Strips all HTML tags from the html, including comments. This uses the html-scanner tokenizer and so its HTML parsing ability is limited by that of html-scanner.

Examples

  strip_tags("Strip <i>these</i> tags!")
  # => Strip these tags!

  strip_tags("<b>Bold</b> no more!  <a href='more.html'>See more here</a>...")
  # => Bold no more!  See more here...

  strip_tags("<div id='top-bar'>Welcome to my website!</div>")
  # => Welcome to my website!
