Requires:
* jQuery (1.2.6 or later)
Usage:
jQuery('.articlebody').linkify();
// adding plugins:
jQuery.extend( jQuery.fn.linkify.plugins, {
name1: {
re: RegExp
tmpl: String/Function
},
name2: function(html){ return html; }
});
// Uses all plugins by default:
jQuery('.articlebody').linkify();
// Use only certain plugins:
jQuery('.articlebody').linkify( 'name1,name2' );
jQuery('.articlebody').linkify({ use: 'name1,name2' });
jQuery('.articlebody').linkify({ use: ['name1','name2'] });
// Explicitly use all plugins:
jQuery('.articlebody').linkify('*');
jQuery('.articlebody').linkify({ use: '*' });
jQuery('.articlebody').linkify({ use: ['*'] });
// Use no plugins:
jQuery('.articlebody').linkify('');
jQuery('.articlebody').linkify({ use: '' });
jQuery('.articlebody').linkify({ use: [] });
jQuery('.articlebody').linkify({ use: [''] });
// Perfmorm actions on all newly created links:
jQuery('.articlebody').linkify( function (links){ links.addClass('linkified'); } );
jQuery('.articlebody').linkify({ handleLinks: function (links){ links.addClass('linkified'); } });
