2. Replace all links withint DOM elements with anchor links.

  "Contact us [email protected]",
  {
    // options here
  }
);

4. Find all links in the given string. Possible types:

'url'
'email'
'hashtag'
'mention'
'ticket'

linkify.find(string, type, options);

5. Test if the given string is a link.

linkify.test('jqueryscript.net'); // true
linkify.test('jqueryscript.net', 'email'); // false

6. Use it as a jQuery plugin.

$(selector).linkify({
  // options
});

<!-- Find and linkify all entities in this div -->
<div data-linkify="this">
  ...
</div>

<!-- Find and linkify the paragraphs and `#footer` element in the body -->
<body data-linkify="p" data-linkify-target="_parent">
  ...
</body>

7. Register a custom protocol.

// linkify.registerCustomProtocol (scheme [, optionalSlashSlash = false])
linkify.registerCustomProtocol("fb");
linkify.registerCustomProtocol("instagram", true);

8. All possible options with default value.

{

  // additional attributes for the links
  attributes: null,

  // default CSS class
  className: 'linkified',

  // default protocol
  defaultProtocol: 'http',

  /* event listeners
    click: function (e) {
      alert('Link clicked!');
    }
  */
  events: null,

  // format the text
  format: function (value, type) {
    return value;
  },

  // format the href
  formatHref: function (href, type) {
    return href;
  },

  // ignore specified HTML tags
  ignoreTags: [],

  // if true, \n line breaks will automatically be converted to <br> tags.
  nl2br: false,

  // rel attribute
  rel: null,

  // Accepts a function that takes the unformatted href, the link type (e.g., 'url', 'email', etc.) and returns the rel string.
  // Accepts an object where each key is the link type and each value is the rel string to use for that type.
  render: null,

  // the tag that should be used to wrap each URL. This is useful for cases where a tags might be innapropriate, or might syntax problems
  tagName: 'a',

  // target attribute for each linkified tag.
  target: {
    url: '_blank'
  },

  // custom validation rules here
  validate: true,

  // truncate link text
  truncate: 0,

}
