They say they want to use Syntax Highlighter and only convert and show it when loading the page for the first time. I want to change the html phrase after adding it to the format with jquery.

You are trying to use Syntax Highlighter. The code is written to look like node.js or input window.

Once I tested it temporarily, I left it for the first time because it wanted to work out, and now I checked it again

<pre class="brush:html;">sdsadsadsa    </pre>

I couldn't convert it even if I added it through jquery according to the format.

Can you tell me how to use Syntax Highlighter? Or, please recommend a code converter other than this.
