show HTML as plain text

问题:

im looking for a way to show html as html without the browser reading it, i found <plainttext> but once i start it i can't stop it for example:

<plaintext>
    <span> dobeediedabiedadadee olleeeeee</span>
</plaintext>
<h1>hi</h1>

in this example the span had to be shown as text and the h1 as a header, but the output is:

    <span> dobeediedabiedadadee olleeeeee</span>
</plaintext>
<h1>hi</h1>

</body>


</html>

The following link describes the difficulty in using <plaintext>. long story short it is not fully supported in any browser and you should be using <pre> instead.

You could always use javascript to escape the HTML. Here is a fiddle.

html.replace(/&/g, "&amp;").replace(/</g, "&lt;").replace(/>/g, "&gt;");

<plaintext> is not a pair tag. From that tag to the rest of the page, everything is interpreted as text. However, this is not standard and obsolette in HTML5:

Examples No, really. don't use it.

It is literally written in the w3 reference
