How is the blinking caret emulated in Etherpad? (See a live version at ietherpad.com) The way I would do it, is to create a div and position it absolutely where the caret should be. Then, display and remove it in regular intervals. However they seem to do it differently.
The text of a row is in
<div id="magicdomid2" class="">...</div>
I can't see anything changing around the开发者_如何学Python div. How is it done?
It isn't emulated. In modern browsers, Etherpad creates an iframe containing a document with the tag:
<body contenteditable="true">
Which tells the browser to allow editing of the contained HTML document. The carat is one of the effects of including that attribute.
