Open window in JavaScript with HTML inserted

Here's how to do it with an HTML Blob, so that you have control over the entire HTML document:

This is the code, but StackOverflow blocks the window from being opened (see the codepen example instead):

const winHtml = `<!DOCTYPE html>
    <html>
        <head>
            <title>Window with Blob</title>
        </head>
        <body>
            <h1>Hello from the new window!</h1>
        </body>
    </html>`;

const winUrl = URL.createObjectURL(
    new Blob([winHtml], { type: "text/html" })
);

const win = window.open(
    winUrl,
    "win",
    `width=800,height=400,screenX=200,screenY=200`
);

When you create a new window using open, it returns a reference to the new window, you can use that reference to write to the newly opened window via its document object.

Here is an example:

var newWin = open('url','windowName','height=300,width=300');
newWin.document.write('html to write...');

I would not recomend you to use document.write as others suggest, because if you will open such window twice your HTML will be duplicated 2 times (or more).

Use innerHTML instead

var win = window.open("", "Title", "toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=780,height=200,top="+(screen.height-400)+",left="+(screen.width-840));
win.document.body.innerHTML = "HTML";

You can use window.open to open a new window/tab(according to browser setting) in javascript.

By using document.write you can write HTML content to the opened window.
