function getEleClass(oParent,className){    var aEles=oParent.getElementsByTagName('*');    var result=[];    for (var i = 0; i < aEles.length; i++) {        if(aEles[i].className==className){            result.push(aEles[i]);        }    };              return result;};-----------------------------------------------------------------<div id="box">    <ul>    <li></li>     <li></li>    <li class="one"></li>    <li class="one"></li>    <li></li>    </ul></div>`<script type="text/javascript">    function getEleClass(oParent,className){        var aEles=oParent.getElementsByTagName('*');        var result=[];        for (var i = 0; i < aEles.length; i++) {            if(aEles[i].className==className){                result.push(aEles[i]);            }        };                  return result;    };    var box = document.getElementById("box")    var aLi=getEleClass(box,"one");    console.log(aLi.length)</script>

注：在调用时oParent传入的必须是一个对象！
