Ticket #5057 (closed bug: invalid)
html('') remove all the children's events
|Reported by:||agate||Owned by:|
$.html(val) will remove all children nodes. and all the events which bind on these children nodes.
but if i use DOM.innerHTML = val, the children's events will be kept. so that i can use append function to append the children back to the dom tree. and the children's evnets still can be triggered.
