Edit HTML and CSS in live mode while also running JavaScript for instant enhancement

Recently, I created a script that allows me to build a web page in real-time. I can input HTML and CSS codes without any issues, but unfortunately, I am unable to execute JavaScript due to the limitations of the string-based editor I am using. Can anyone offer some guidance on how to enable JavaScript execution in this editor?

It's worth noting that this simple script allows me to input an entire webpage's code with CSS and HTML seamlessly, without any need for escaping characters, resulting in a formatted page. However, JavaScript functionality is not supported by this script.

function html() {
var str = document.getElementById("go").value;
  document.getElementById("show").innerHTML = str;   
}

<p id="show"></p>
<textarea id="go" onKeyUp="html()"  width="100%" cols="50" rows="10">
   </textarea>

UPDATE: Exciting news - I finally found a solution that allows this editor to execute JavaScript as well! Now, I can create a complete webpage with JavaScript functionalities integrated. Huge thanks to everyone who provided assistance!

$(document).ready(function(){
  $('#editor').keyup(function(){
      $('#page').html($(this).val());
  });
   });

<p id="page"></p>
 <textarea id="editor"  width="100%" cols="50" rows="10" placeholder="you can use HTML, CSS, and JavaScript here..."></textarea>
 <script src="http://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

Answer №1

All of your content is being placed within paragraph tags, which is why any content within script tags is not functioning properly. Consider appending everything within the body tag instead:

function html() {
  var str = document.getElementById("go").value;
  document.getElementsByTagName("body")[0].innerHTML = str;   
}

Could you please provide more clarity on your request to "find a way to execute javascript in this editor?" What specific outcomes are you hoping to achieve?

Executing JavaScript code automatically is not recommended, as it poses security risks. An alternative approach is to use the eval() function to run the code. Here's a sample implementation:

Although using eval() increases security risks, it may be necessary in certain scenarios.

function displayContent() {
var inputContent = document.getElementById("inputField").value;
  document.getElementById("output").innerHTML = inputContent;   
}

function executeCode() {
var codeToRun = document.getElementById("codeField").value;
  document.getElementById("output").innerHTML = eval(codeToRun);   
}

<p id="output"></p>
<textarea id="inputField" onKeyUp="displayContent()"  width="100%" cols="50" rows="10"> </textarea>
<textarea id="codeField" width="100%" cols="50" rows="10"> </textarea>
<br><button onclick="executeCode()">Run Code</button>
