On the site I'm working on, we have some span tags with IDs. The spans
are initially rendered on the page with no text content. When certain
events happen, text error messages are loaded into these spans. I want
to write an additional handler that is triggered when the text content
of the span is changed. The onchange(jquery change) event doesn't fire
on non-form elements. I suspect I can utilize DOM Mutation events,
however the support for these is not universal, especially in IE. Has
someone else worked out a solution for this? I can jank it and use a
timer, but that is messy and causes additional load in the page.
