For a recent project, it is necessary to sort the output of the data, which requires the line number and the sequential increment of 1.2.3.4.5… .

Front pass < C: forEach> Traversing dynamic output < Tr> , the code is as follows:

<!--  Loop generate list data  -->
<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"> RMB: ${auction.auctionSum}.00</td>
<td width="40" align="center"><span onClick="displayDetails('xxxx}')" style="color:blue;cursor:pointer;"> View details </span></td>
</tr>
</c:forEach>

Line number self-increment js code (jquery is needed) :

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