Pasting code from a text input field into a function

On my page, there is a textarea labeled "Program" where users can input JavaScript code. When submitted, the page will execute this code and display the result in an output window.

One idea I had for implementing this feature was to copy the content of the Program textarea into an empty function and then call that function for execution. Since I am still learning JavaScript, I am unsure if this approach is feasible. Any guidance on this matter would be greatly appreciated!

Answer №1

functionToExecute = new Function(textAreaContent.value);

However, it is requested to place it inside an iframe element.

iframeElement.srcdoc = "<!DOCTYPE html><html><head><script>"+textAreaContent.value+"</script></head><body>Additional content can be inserted here.</body></html>";
