Here is another try: How about before executing the mutation method macro, we insert a transient node after `oldNode`, suppressing observers. Then run the mutation method macro, pre-insert `node` before the transient node and finally remove the transient node, suppressing observers.
Idea comes from Andrea’s DOM4 library: https://github.com/WebReflection/dom4/commit/ffc8cbdf88fa98627dd82cf11084a0660b9bbfc0 <https://github.com/WebReflection/dom4/commit/ffc8cbdf88fa98627dd82cf11084a0660b9bbfc0> > On Jan 16, 2015, at 4:22 PM, Anne van Kesteren <ann...@annevk.nl> wrote: > > On Fri, Jan 16, 2015 at 8:47 AM, Glen Huang <curvedm...@gmail.com> wrote: >> Another way to do this is that in mutation method macro, prevent `oldNode` >> from being added to the doc frag, and after that, insert the doc frag before >> `oldNode`, finally remove `oldNode`.
