How do I make a link open in a new tab with the url shown as "about:blank"-CodePudding

When I click the "click now" button nothing happens, I want it to open in a new tab. Code:

<button onclick="myFunction()">click to play</button> 
<script>

    var urlObj = new window.URL(window.location.href);
    var url = "https://incognito42.herokuapp.com/src/gs/public/hexgl/";

    if (url) {
        var win;

        document.querySelector('button').onclick = function()

I've tried rewriting it like this:

<html>
  <body>
    <button onclick="myFunction()">click to play</button>
    <script>
      function myFunction() {
           var win = window.open(
                            "https://incognito42.herokuapp.com/src/gs/public/vex5/",
                            "DescriptiveWindowName",
                            "width=1920,height=1080,resizable,scrollbars=no,status=1"
                            );
        myWindow.document.write('<html><head> <title>Sample</title><link rel="stylesheet" type="text/css" href="css/newsCSSWindow.css"></head><body>');
        myWindow.document.write("Sample Window");
        myWindow.document.write('</body></html>');
      }
    </script>
  </body>
</html>

but then it doesn't open in a new tab with the URL shown as "about:blank", and just to be clear I want the URL bar to say "about:blank", but it displaying the link's contents shown on the page.

this page for reference

CodePudding user response：

You can't.

While you could fix your trivial errors:

The URL you entered as the first argument to window.open isn't about:blank
You forgot the , after that first argument
You have var win and then myWindow.document.write

… the browser will change the displayed URL to reflect where the data from.

Browsers do not let webpages deceive users about the source of what they are looking at.

I suspect that you meant it if you do not write in the comment exactly what

<!DOCTYPE html>
<html>
<head>

</head>
  <body>
    <button onclick="myFunction()">click to play</button> 
    <script>
      function myFunction(){
        var urlObj = new window.URL(window.location.href);
        var url = "https://incognito42.herokuapp.com/src/gs/public/hexgl/";
      
        if (url) {
            var win;
    
            document.querySelector('button').onclick = window.open(url)}
        }
    </script>
  </body>
</html>
