推荐答案

更整洁，而不是典型的 href="#" 或 href="javascript:void" 或 href="whatever"，我认为这更有意义:

Neater still, instead of the typical href="#" or href="javascript:void" or href="whatever", I think this makes much more sense:

var el = document.getElementById('foo');
el.onclick = showFoo;


function showFoo() {
  alert('I am foo!');
  return false;
}

<a href="no-javascript.html" title="Get some foo!" id="foo">Show me some foo</a>

如果 Javascript 失败，会有一些反馈.此外，还消除了不稳定行为(href="#" 情况下的页面跳转，href="" 情况下访问同一页面).

If Javascript fails, there is some feedback. Furthermore, erratic behavior (page jumping in the case of href="#", visiting the same page in the case of href="") is eliminated.
