How do I get value from ACE editor?

Per their API:

Markup:

<div id="aceEditor" style="height: 500px; width: 500px">some text</div>

Finding an instance:

var editor = ace.edit("aceEditor");

Getting/Setting Values:

var code = editor.getValue();

editor.setValue("new code here");

Based on my experience, Ace is the best code editor I’ve seen. There are few others such as CodeMirror etc. but I found them to be less useful or difficult to integrate than Ace.

Here’s a Wiki page for comparision of such editors.

There is a paid one also which I haven’t tried (and I can’t remember for now). Will updated later if I can find it.
