Making URL clickable in read only mode

Hello,

I  have a filed which of type URL. I want this field as read only but at the same time I want it clickable so that user can open it. I can use

 Xrm.Page.ui.controls.get("filedname").setDisabled(false);
          document.all.filedname.contentEditable = "false";

But i guess its not supported. Can any one suggest me supported solution for this?

Thanks in advance,
