jQuery.event.special.mutate
Wraps the MutationObserver API. Options maps to MutationObserver
options.
Usage
$('body').on('mutate', options, function(e, mutation){
// handle event...
});
// unless you want to handle the specific mutation record, it's more efficient to set a timeout
var mutateTimeout;
$('body').on('mutate', options, function(e){
clearTimeout(mutateTimeout);
mutateTimeout = setTimeout(function(){ /* ... */ }, 500);
});
