ep_embed_floating_toolbar

An Etherpad Lite plugin that enables floating toolbar & messages even when embedded and the frame height is always set to fit content (using ep_resize plugin https://github.com/tiblu/ep_resize). Applies also to timeslider view.

Usage example

In order to float the toolbars, the embedded frame needs to know about the embedding pages scroll position and the embedded frames position. postMessage (https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage) is used for cross-domain communication between the parent page and the frame.

Assuming you use JQuery parent page can send the scroll positions to the child frame as follows:

    $(window).on('scroll', function (e) {
        var $myPadFrame = $('#myPadFrame');
        var targetWindow = $myPadFrame.get(0).contentWindow;
        targetWindow.postMessage({
            name: 'ep_embed_floating_toolbar_scroll',
            data: {
                scroll: {
                    top: $(window).scrollTop(),
                    left: $(window).scrollLeft()
                },
                frameOffset: $myPadFrame.offset() // Iframe offset on the page so that we know when to start floating the toolbars
            }
        }, '*');
    });

When making single page webapps, don't forget to remove scroll handler when the view is destroyed.

    $(window).off('scroll');
