        return res;
    </div>
</body>
<script>
var txt=document.getElementById("code").innerHTML;
document.write(txt);
//  输出：var res = a > b ? a: b;
//  res = res > c ? res : c;
//  return res;
//原因是用document.write输出时会对已转义的字符再次转义。
alert(txt);
//  输出：var res = a &gt; b ? a: b;
//  res = res &gt; c ? res : c;
//  return res;
var str = txt.replace(/&gt;/g,">");

//  res = res > c ? res : c;
