问题 I'm trying to modify all links on a page so they perform some additional work when they are clicked. A trivial approach might be something like this: function adaptLinks() { var links = document.getElementsByTagName('a'); for(i = 0; i != links.length; i++) { links[i].onclick = function (e) { <do some work> return true; } } } But some of the links already have an onClick handler that should be preserved.
