How can I target the code contained in a prism.js script?


What I'm trying to do:

I use prism.js to display blocks of code. The idea is to be able to also display the visual rendering of this code, in the same window.

What I managed to do:

<button class="flip">See the code</button>
<div class="result"></div>
<div class="code">
<pre class="language-markup"><code class="language-markup"><script class="script" type="text/plain">
....here is my html code...
</script></code></pre>
</div>

As I have many code blocks like this, I thought using each and click functions, something like this :

$('.flip').each(function(){
  $(this).on('click',function(){
    var code = $(this).next('.code').html();//get the html code from the html block
  var result = $(this).next('.result').text(code);// inject it in the result block
  $(this).next('.code,.result').toggleClass('hide');// toggle to show code or result..
  
})
}) 

But it does nothing. Even If I target the pre tag, code or script tag, using html(), val(), or text() it doesn't work..

Any help would be appreciated..

EDIT: thanks to Swati answer it works. If I want to do the opposite, i.e. first display the visual rendering and then click on the button, the corresponding code, it's possible too. Here is my test :

$(".code").hide();
$('.flip').each(function(){
    var code_block = $(this).nextAll('.code:first');
    var preview_div = $(this).next('.result');
    preview_div.html(code_block.find("code.language-markup").text());    //add your html in result div...
}) 

    $(".flip").click(function() {
        var code_block = $(this).nextAll('.code:first');
        var preview_div = $(this).next('.result');

   //run or show codes..block
    if ($(this).text().trim() == "See the code") {
        $(this).text('Run Code')
        // preview_div.html(code_block.find("code.language-markup").text());    //add your html in result div...
        preview_div.show();
        code_block.hide();
    } else {
        $(this).text('See the code')
        

        code_block.show();
        preview_div.hide();
    }

Solution

  • You can get the code block and result div using nextAll('.code:first') and next('.result') and depending on the condition show or hide your code or result div.

    Demo Code :

    $(".result").hide()
    
    $(".flip").click(function() {
    
      var code_block = $(this).nextAll('.code:first');
      var preview_div = $(this).next('.result');
    
       //run or show codes..block
      if ($(this).text().trim() == "Run Code") {
        $(this).text('See the code')
        preview_div.html(code_block.find("code.language-markup").text());    //add your html in result div...
        code_block.hide()
        preview_div.show()
      } else {
        $(this).text('Run Code')
        preview_div.hide()
        code_block.show()
      }
    
    })

    " rel="stylesheet">
    
    <button class="flip">Run Code</button>
    <div class="result"></div>
    <div class="code">
      <pre class="language-markup">
      <code class="language-markup">
      <script class="script" type="text/plain">
      <img src="https://i.pinimg.com/originals/1f/65/30/1f65303066ef5e14cad11da3c6eeef0d.jpg" width="50px" height="50px">
      <ul>
      <li><a href="#home">Home</a></li>
      <li><a href="#news">News</a></li>
      <li><a href="#contact">Contact</a></li>
      <li><a href="#about">About</a></li>
     </ul>
    </script>
    </code>
    </pre>
    </div>
    <button class="flip">Run Code</button>
    <div class="result">
    </div>
    <div class="code">
      <pre class="language-markup">
      <code class="language-markup">
       <script class="script" type="text/plain">
       <p>XYZ..something <input type="text"/></p>
       </script>
    </code>
    </pre>
    </div>

    Other way : You can have same html in your result div as well and whenever you click on the button just toggle divs.

    $(".result").hide()
    
    $(".flip").click(function() {
    
      var code_block = $(this).nextAll('.code:first');
      var preview_div = $(this).next('.result');
    
      if ($(this).text().trim() == "Run Code") {
        $(this).text('See the code')
        code_block.hide()
        preview_div.show()
      } else {
        $(this).text('Run Code')
        preview_div.hide()
        code_block.show()
      }
    
    })
