html - 表示方法文字通りタグ/ tag?

Answer 1

Unfortunately it doesn't work with HTML tags.

<code> means "This is code", <pre> means "White space in this markup is significant". Neither means "The content of this element should not be treated as HTML", so both work perfectly, even if they don't mean what you want them to mean.

Is there any way to show "<div>" inside of <pre> or <code> tag without actually interpreting it as HTML?

If you want to render a < character then use <, with > for > and & for &.

You can't (in modern HTML) write markup and have it be interpreted as text.

Answer 2

It seems like a readonly textarea does pretty much what you want.

<textarea readonly> <!-- html code --> </textarea>

Answer 3

You can use the "xmp" element. The <xmp></xmp> has been in HTML since the beginning and is supported by all browsers. Even it should not be used, it is broadly supported.

Everything inside <xmp></xmp> is taken as it is (no markup lke tags or character references is recognized there) except, for apparent reason, the end tag of the element itself.

Otherwise "xmp" is rendered like "pre".

Answer 4

Try:

<xmp></xmp>

for exemple:

<pre>
     <xmp><!-- your html code --></xmp>
</pre>

bye

Answer 5

Just escape the HTML tags. For example -

Replace < with <

Replace > with >

Answer 6

This can be easily achieved with a little bit of javascript.

document.querySelectorAll("code").forEach(el => el.innerText = el.innerHTML);

Run snippet below to see it in action:

document.querySelectorAll("code").forEach(el => el.innerText = el.innerHTML);

pre {
  padding: 1rem;
  background-color: #eee;
  border-radius: 0.25rem;
}

<pre>
  <code>
   .class {        
     color:red;
   }
   
   // I would like HTML code inside this
   <h1>Hello this is a heading</h1>
  </code>
</pre>

Answer 7

Try CodeMirror (https://codemirror.net/)

It's a lightweight library that styles code in HTML. Here's a screenshot of what I'm referring to:

Worked well for us!

Answer 8

Maybe not the best answer, but you can do something like this:

<p><<input type="hidden">h1<input type="hidden">><input type="hidden">This code is 
displayed!<input type="hidden"><<input type="hidden">/h1<input type="hidden">></p>

<p><<input type="hidden">h1<input type="hidden">><input type="hidden">This code is displayed!<input type="hidden"><<input type="hidden">/h1<input type="hidden">></p>

Answer 9

<pre>
  <code><textarea>
    <div>Now you can write Tags inside pre tag!</div>
  </textarea><code>
 <pre>

Answer 10

Use this:

<pre>
   <?= htmlentities($script) ?>
</pre>

Answer 11

Yes, with an escape xml function. You'll need to have jQuery enabled for it to work though.

<pre>
  ${fn:escapeXml('
    <!-- all your code -->
  ')};
</pre>
