Error with popup overlay in OpenLayers 3?

Question

In OpenLayers (OL) 3.15.0 I declare a popup contains like :

popup = $(eval('<div id="popup"><p>My contain</p></div>'));

And after, I declare my overly with this popup element :

var overlay_popup = new ol.Overlay({
                        element: popup
                    });

On OL 3.7.0 I've any problem all was okay.

But now with this new version of OL (3.15.0) Firebug say :

TypeError: Argument 1 of Node.appendChild does not implement interface Node.

What can I do for working ?

Answer 1

You must declare this : element: popup[0]
