Answer 1

Are you trying to do something like below? You need to include jquery library files, and then below will work. In the code I have fixed: at the end of line 1 to;

 var myhref = window.location.href + '/1/'; $('.the-tag p').replaceWith('<a href="' + myhref + '">My Link</a>');

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="the-tag"> <p></p> </div>

Some problems with your current script...

1. Your first line is terminated with : which causes a syntax error. You probably meant ;
2. To concatenate strings in JS, you use the + operator
3. Your script appends /1/ to the end of the complete URL. If the URL contains query parameters or fragments, this will cause problems. You should manipulate the path property only

 // Show an example with a fragment location location.hash = "#anchor" // Clone the current URL const myhref = new URL(location) // Handles cases where the current path // does or does not end in a "/" myhref.pathname = myhref.pathname.replace(/\/?$/, "/1/") $('.the-tag p').replaceWith($("<a>", { href: myhref, text: "My Link" }))

 /* This is just so you can see the href */ a::after { content: " (" attr(href) ")"; color: grey; font-size: .8rem; }

 <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha256-4+XzXVhsDmqanXGHaHvgh1gMQKX40OUvDEBTu8JcmNs=" crossorigin="anonymous"></script> <div class="the-tag" id="anchor"> <p></p> </div>

You should do this instead

var myhref = window.location.href+'/1/';
$.('.the-tag p').replaceWith('<a href="'+ myhref +'">My Link</a>');

And also you should ensure that you have the Jquery library included added in your code as well.
