change ip inside link using javascript

so my goal is to change ip address in link with user's current ip. This is script for returing current user ip address.

<script type="text/javascript" src="https://l2.io/ip.js?var=userip"></script>
<script type="text/javascript">
  var userip;
  document.write(userip); // write to html
</script>

Link example:

www.mysite.com/data/uploads/file.mp3?e=14512&ip=IPHERE&amp=blbablaba&next=fasfass

How can I make to write user's ip to "IPHERE" place and link will look like:

<a href="www.mysite.com/data/uploads/file.mp3?e=14512&ip=123.123.123.123&amp=blbablaba&next=fasfass">link with ip</a>

without changing anything else.

Thanks.

Solution

  • You can search for all a tags and replace href:

    [].slice.call(document.querySelectorAll('a')).forEach(function(a) {
    a.href = a.href.replace(/IPHERE/g, userip);
});
