Finding Specific text in body and removing it via JS

I am creating HTML and ASPX file via C# code in APX everything works fine but in HTML page it appends the aspx tag which shows as plain text in body. i want to remove any text in body that starts with <% and ends with %>

here is the generated html

<body>
   <center>
 <%String action = "http://" + Request.Url.Authority+"/ABC/Data/a12.aspx" ; %>
     <div>
        <form>
          // some input fields and a submit button
        </form>
     </div>
   </center>
</body>

I have tried 

document.body.innerHTML = document.body.innerHTML.replace( <%String action = "http://" + Request.Url.Authority+"/ABC/Data/a12.aspx" ; %>, "");

but didn't work for me, as the generated aspx tag is not same all the time..

Code Render Blocks shouldn't be rendered in HTML pages unless you're using them wrong. Try to modify your markup as follows:

<body>
   <center>
     <div>
        <form action='<%= "http://" + Request.Url.Authority + "/ABC/Data/a12.aspx" %>'>
          // some input fields and a submit button
        </form>
     </div>
   </center>
</body>

By using regular expression, I guess this should give what you need:

<script>
  document.body.innerHTML = document.body.innerHTML.replace(/(<%).*(%>)/ig, '');
</script>

In this code:

document.body.innerHTML = document.body.innerHTML
    .replace( <%String action = "http://" + Request.Url.Authority+"/ABC/Data/a12.aspx" ; %>, "");

You are: not using a string as the first argument, this is invalid.

I would suggest you to use a regex, that matches <% [anything] %>.

Like this: 

document.body.innerHTML = document.body.innerHTML
    .replace(/<%.*%>/g, "");
