Getting the textarea value of a ckeditor textarea with javascript

Question

I'm a learner as far as JS goes and although I've spent a good few hours reading through tutorials which has helped lots but I'm still having problems figuring out exactly how I find out what a user is typing into a ckeditor textarea.

What I'm trying to do is have it so that when someone types into the textarea, whatever they type appears in a div in a different part of the page.

I've got a simple text input doing that just fine but because the text area is a ckEditor the similar code doesn't work.

I know the answer is here: ckEditor API textarea value but I don't know enough to figure out what I'm meant to do. I don't suppose anyone fancies helping me out?

The code I've got working is:

$('#CampaignTitle').bind("propertychange input", function() {   $('#titleBar').text(this.value); }); 

and

<label for="CampaignTitle">Title</label> <input name="data[Campaign][title]" type="text" id="CampaignTitle" /> 

and

<div id="titleBar" style="max-width:960px; max-height:76px;"></div>

I'm still having problems figuring out exactly how I find out what a user is typing into a ckeditor textarea.

Ok, this is fairly easy. Assuming your editor is named "editor1", this will give you an alert with your its contents:

alert(CKEDITOR.instances.editor1.getData()); 

The harder part is detecting when the user types. From what I can tell, there isn't actually support to do that (and I'm not too impressed with the documentation btw). See this article: http://alfonsoml.blogspot.com/2011/03/onchange-event-for-ckeditor.html

Instead, I would suggest setting a timer that is going to continuously update your second div with the value of the textarea:

timer = setInterval(updateDiv,100); function updateDiv(){     var editorText = CKEDITOR.instances.editor1.getData();     $('#trackingDiv').html(editorText); } 

This seems to work just fine. Here's the entire thing for clarity:

<textarea id="editor1" name="editor1">This is sample text</textarea>  <div id="trackingDiv" ></div>  <script type="text/javascript">     CKEDITOR.replace( 'editor1' );      timer = setInterval(updateDiv,100);     function updateDiv(){         var editorText = CKEDITOR.instances.editor1.getData();         $('#trackingDiv').html(editorText);     } </script>

At least as of CKEDITOR 4.4.5, you can set up a listener for every change to the editor's contents, rather than running a timer:

CKEDITOR.on("instanceCreated", function(event) {     event.editor.on("change", function () {         $("#trackingDiv").html(event.editor.getData());     }); }); 

I realize this may be too late for the OP, and doesn't show as the correct answer or have any votes (yet), but I thought I'd update the post for future readers.
