<p>Writing to a document that has already loaded without calling {{domxref("document.open()")}} will automatically call <code>document.open</code>. Once you have finished writing, it is recommended to call {{domxref("document.close()")}} to tell the browser to finish loading the page. The text you write is parsed into the document's structure model. In the example above, the <code>h1</code> element becomes a node in the document.</p>

<p>If the <code>document.write()</code> call is embedded within an inlined HTML <code>&lt;script&gt;</code> tag, then it will not call <code>document.open()</code>. For example:</p>

<pre class="brush: html">&lt;script&gt;
  document.write("&lt;h1&gt;Main title&lt;/h1&gt;")
&lt;/script&gt;
</pre>

<div class="note"><strong>Note</strong>: <code>document.write</code> and <code>document.writeln</code> <a href="/en-US/docs/Archive/Web/Writing_JavaScript_for_HTML">do not work in XHTML documents</a> (you'll get a "Operation is not supported" [<code>NS_ERROR_DOM_NOT_SUPPORTED_ERR</code>] error in the error console). This happens when opening a local file with the .xhtml file extension or for any document served with an <code>application/xhtml+xml</code> {{Glossary("MIME type")}}. More information is available in the <a class="external" href="http://www.w3.org/MarkUp/2004/xhtml-faq#docwrite">W3C XHTML FAQ</a>.</div>

<div class="note"><strong>Note</strong>: <code>document.write</code> in <a href="/en-US/docs/Web/HTML/Element/script#attr-defer">deferred</a> or <a href="/en-US/docs/Web/HTML/Element/script#attr-async">asynchronous</a> scripts will be ignored, and you'll get a message like "A call to <code>document.write()</code> from an asynchronously-loaded external script was ignored" in the error console.</div>

<div class="note"><strong>Note</strong>: In Edge only, calling <code>document.write</code> more than once in an iframe causes the error SCRIPT70: Permission denied.</div>
