推荐答案

如果你必须用普通的 javascript 来做它会很痛苦，因为 Internet Explorer 不支持 getElementsByClassName()(也许在新版本中?).

If you have to do it in plain javascript it'll be painful because of Internet Explorer which doesn't support getElementsByClassName() (maybe in newer version ?).

var elems = document.getElementsByTagName('p');
var elemsLenght = elems.lenght;
for (var i = 0; i < elemsLenght; ++i) {
{
  if (elems[i].className == 'classname')
  {
      elems[i].innerHTML = '';
  }
}

但如果可以，请使用 jQuery、prototype、dojo 等库/框架.

But if you can, use a library/framework like jQuery, prototype, dojo, etc..
