非常简单的XMLHttpRequest对象问题

这段代码在FF、IE下都能够正确输出request.responseText。但在oprea下，却获取不到responseText的值，有大虾知道的吗，帮我看看... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  1.   

    国内的网站 需要 测试 oprea吗 ？
      

  2.   

    上面的代码复制错了，这才是正确的，大虾们帮忙看看 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
