There is a text line like
var text = "somthing text and habrahabr.ru/login.php?vk=1 link " Link taken from the baldy. It is necessary in any way to make the replacement of this line with a link And not only of this kind.
What else should be considered:
- support for these protocols (i.e. conversion to a link): http: //, https: //, ftp: //, skype: //, steam: //
- any domain names (such as .рф) and support for subdomains proper
- Cyrillic domain name support
All this is wrapped in a function, for example. Already written and partially working:
function findAndReplaceLink(inputText) { var url = "http://test.com" var pattern = /([-a-zA-Z0-9@:%_\+.~#?&\/\/=]{2,256}\.[a-zA-Zа-яА-ЯёЁ]{2,4}\b(\/?[-a-zA-Z0-9а-яА-ЯёЁ@:%_\+.~#?&\/\/=]*)?)/gi; var replacedText = inputText.replace(pattern, '<a href="'+url+'/go.php?to=$1" target="_blank">$1</a>'); return replacedText; } The output should be the line:
"somthing text and <a href='http://test.com/go.php?to=http://habrahabr.ru/login.php?vk=1' target='_blank'>habrahabr.ru/login.php?vk=1</a> link " Help, please, finish the functionality. Thanks in advance.
UPDATE. I found a code with a similar functionality (I took it from vk.com), but I don’t know how to change it for my needs, for my function. will not help?
