JS 排序输出实现table行号自增前端动态生成的tr

<!-- 循环生成，列表数据 --> <c:forEach items="${pager.list}" var="auction"> <tr class="bg1"> <td width="10" align="center"><span class="numberClass"></span></td> <td width="30" align="center">${auction.dept}</td> <td width="40" align="center">${auction.donor}</td> <td width="40" align="center">￥：${auction.auctionSum}.00</td> <td width="40" align="center"><span onClick="displayDetails('xxxx}')" style="color:blue;cursor:pointer;">查看详细信息</span></td> </tr> </c:forEach>

$(function(){ function number(){ for(var i=0;i< $(".numberClass").length;i++){ $(".numberClass").get(i).innerHTML = i+1; } } number(); });
