给出未在源代码中设置的链接的运行时href

Question

How to give href of a link that set in runtime not in html source code:

there is a download link in a webpage:

<a id="downloadLink" href="">...</a>

but in runtime that link has a href:

<a id="downloadLink" href="http://www.example.com/download/s/eyJjdCI6IkFpc003OERmME1uS3dhR1BQcXg1ckE9PSIsIml2IjoiNzg0OGI5NWRmMmRjZDg0ZjFlMjVjYTM3MjY1MjdjMTUiLCJzIjoiYjU1NTIyN2Q2MmJiODAyMSJ9.mp3">...</a>

I searched in html source and find that it use jquery aes to encrypt and set the link.

How can I access to runtime source code by PHP? file_get_contents() give me source html code not runtime code

Answer 1

with use of PHP

<a id="downloadLink" href="<?php echo $url?>" download></a>

with use of Jquery

 <script>
    $(document).ready(function(){
      $("#downloadLink").attr('href','[e-mail]');
      $("#downloadLink").attr('download','download');
    });
  </script>

I hope the above code helps
