Save Automatically?

If active, Pens will autosave every 30 seconds after being saved once.

Want a Run Button?

If active, the preview will update automatically when you change code.


              <textarea>Holy smurfs!</textarea><br>
<button>Move cursor to end of textarea</button>




              $("button").on("click", function() {
  // cache textarea as we need it more than once
  var textarea = $("textarea"),
      // save old value as we need to clear it
      val = textarea.val();
  // if the value doesn't end in a space, add one
  if (val.charAt(val.length-1) != " ") {
    val += " ";
  // focus textarea, clear value, re-apply

Asset uploading is a PRO feature.

As a PRO member, you can drag-and-drop upload files here to use as resources. Images, Libraries, JSON data... anything you want. You can even edit them anytime, like any other code on CodePen.
