This file exposes a utility function that will invoke its callback once the
document.body tag has been created by the runtime environment. It is
intended to be used in the case of scripts that execute synchronously in the
head of a document, prior to document.body being available, yet having a
dependency on document.body for some reason (e.g. appending DOM nodes). This
function uses a MutationObserver in order to function, so requires that level
of support in order to function.
var waitForBody = require('bv-ui-core/lib/waitForBody');
var div = document.createElement('div');
div.id = 'modalContainer';
waitForBody(function () {
document.body.appendChild(div);
});
