Get text from CK Editor textarea in JQuery

Question

I am using CK Editor in an app.

<textarea name="contentDetails" id="contentDetails" rows="10" cols="80"></textarea>

But I can't retrieve text from that textarea. I've tried-

 var content= $("#contentDetails").text(); //and also .val() & .html()

But content variable remains empty.

Any idea?

//UPDATE - add my codes below
<script>
CKEDITOR.replace('contentDetails');

$(function () {
    $("#submitcontent").click(function (e) {
        e.preventDefault();
       var content= $("#contentDetails").text();           
    });
});

</script>

Answer 1

Use:

var text = CKEDITOR.instances.contentDetails.getData();
