document.write("<h2>Hello World!</h2><p>Have a nice day!</p>");
Try it Yourself »

Using document.write() after a document is loaded, deletes all existing HTML:

// This should be avoided:
function myFunction() {
  document.write("Hello World!");
}
Try it Yourself »

More examples below.


Definition and Usage

The write() method writes directly to an open (HTML) document stream.

Warning

The write() method deletes all existing HTML when used on a loaded document.

The write() method cannot be used in XHTML or XML.

Note

The write() method is most often used to write to output streams opened by the the open() method.

See "More Examples" below.

The Document writeln() Method

The Document open() Method

The Document close() Method

exp2,
exp3,
...
Optional.

document.close();
Try it Yourself »

Open a new window and write some HTML into it:

const myWindow = window.open();
myWindow.document.write("<h1>New Window</h1>");
myWindow.document.write("<p>Hello World!</p>");
Try it Yourself »

The Difference Between write() and writeln()

write() and writeln():

<body>

<p>Note that write() does NOT add a new line after each statement:</p>
<pre>
<script>
document.write("Hello World!");
document.write("Have a nice day!");
</script>
</pre>

<p>Note that writeln() adds a new line after each statement:</p>
<pre>
<script>
document.writeln("Hello World!");
document.writeln("Have a nice day!");
</script>
</pre>

</body>
Try it Yourself »

It makes no sence to use writeln() in HTML.

If you want new lines in HTML, you must use paragraphs or <br>:

document.write("Hello World!<br>");
document.write("Have a nice day!");
Try it Yourself »
