如何在一个jsp显示3 ArrayList中的？ [英] how to display 3 arraylist's in a jsp?

问题描述

我在一个表中显示3数组列表..在的ArrayList是从一个servlet转发。值要来的JSP。好像我们显示仅PRG是沃金，但可显示3数组列表一个阵列列表是一个问题。

  c为C：VAR的forEach =auctionDO项=$ {} auctionDOListServlet＆GT;
＆LT; TR DIV CLASS =奇＆GT;
    ＆LT; TD风格=FONT-SIZE：14px的;＆GT;＆LT; A HREF =/ myproject的/ S / PermanentUserAuctionHistoryInner＆GT;＆LT; C：从价值=$ {auctionDO.auctionName}/＆GT; ＆所述; / A＆GT;＆下; / TD＆GT;
    ＆LT; TD＆GT; c为C：出值=$ {} auctionDO.endDate/＆GT; ＆LT; / TD＆GT;
    ＆LT; TD＆GT; c为C：出值=$ {} auctionDO.status/＆GT;＆LT; / TD＆GT;
    ＆LT; TD＆GT; c为C：出值=$ {} depotDo.depotName/＆GT;＆LT; / TD＆GT;
    ＆LT; TD＆GT; c为C：出值=$ {} userAuctionRelDo.bidAmt/＆GT;＆LT; / TD＆GT;
＆LT; / TR＆GT;
＆LT; / C：的forEach＆GT;
 

如auctionDOListServlet中的foreach提供其显示正确..未显示depotDO和userAuctionRelDO ..

如何显示其他2的ArrayList ??

在的ArrayList是从Servlet进行传递如下：

 了request.setAttribute（auctionDOListServlet，auctionDOListServlet）;
了request.setAttribute（depotDOListServlet，depotDOListServlet）;
了request.setAttribute（userAuctionRelDOListServlet，userAuctionRelDOListServlet）;
 

我已经合并三个列表分为1列表

  megaList.addAll（auctionDOListServlet）;
megaList.addAll（depotDOListServlet）;
megaList.addAll（userAuctionRelDOListServlet）;
 

现在如何显示此为每个？将这项工作？
其中，兆是变量??

的名称

 ＆LT; TD＆GT; c为C：出值=$ {} mega.endDate/＆GT; ＆LT; / TD＆GT;
 

这怎么样了，现在车厂为名称和bidamt错误，因为他们是在一个完全不同的DO ..笏办??

解决方案

  

如何显示其他2的ArrayList ??

当你做了。 depotDOListServlet 和 userAuctionRelDOListServlet 两个数组列表，然后同样的方式，可以使用 c为C：的forEach＆GT ;＆LT; / C：的forEach＆GT; 来遍历这些名单

  c为C：VAR的forEach =auctionDO项=$ {} auctionDOListServlet＆GT;
 ＆LT; TR DIV CLASS =奇＆GT;
  ＆LT; TD风格=FONT-SIZE：14px的;＆GT;＆LT; A HREF =/ myproject的/ S / PermanentUserAuctionHistoryInner＆GT;＆LT; C：从价值=$ {auctionDO.auctionName}/＆GT; ＆所述; / A＆GT;＆下; / TD＆GT;
  ＆LT; TD＆GT; c为C：出值=$ {} auctionDO.endDate/＆GT; ＆LT; / TD＆GT;
  ＆LT; TD＆GT; c为C：出值=$ {} auctionDO.status/＆GT;＆LT; / TD＆GT;
  c为C：VAR的forEach =depotDo项=$ {} depotDOListServlet＆GT;
   ＆LT; TD＆GT; c为C：出值=$ {} depotDo.depotName/＆GT;＆LT; / TD＆GT;
  ＆LT; / C：的forEach＆GT;
  c为C：VAR的forEach =userAuctionRelDo项=$ {} userAuctionRelDOListServlet＆GT;
   ＆LT; TD＆GT; c为C：出值=$ {} userAuctionRelDo.bidAmt/＆GT;＆LT; / TD＆GT;
  ＆LT; / C：的forEach＆GT;
 ＆LT; / TR＆GT;
＆LT; / C：的forEach＆GT;
 

记住对于列表中的每个项目 auctionDOListServlet 休息两个列表，每次将迭代。

i have to display 3 array lists in a table.. the arraylists are forwarded from a servlet. the value s coming to the jsp. as if we display one array list alone the prg is woking but to display 3 array lists is a problem.

<c:forEach var="auctionDO" items="${auctionDOListServlet}">
<tr div class="odd"> 
    <td style="font-size:14px;"><a href="/myproject/s/PermanentUserAuctionHistoryInner"><c:out value="${auctionDO.auctionName}"/> </a></td>
    <td><c:out value="${auctionDO.endDate}"/>   </td>
    <td><c:out value="${auctionDO.status}"/></td>
    <td><c:out value="${depotDo.depotName}"/></td>
    <td><c:out value="${userAuctionRelDo.bidAmt}"/></td>
</tr>
</c:forEach>

as auctionDOListServlet is provided in foreach its displaying correctly.. the depotDO and userAuctionRelDO is not being displayed..

how do i display the other 2 arraylists??

the arraylists are passed from servlet as follows

request.setAttribute("auctionDOListServlet", auctionDOListServlet);
request.setAttribute("depotDOListServlet", depotDOListServlet);
request.setAttribute("userAuctionRelDOListServlet", userAuctionRelDOListServlet);

i have combined the three list into 1 list

megaList.addAll(auctionDOListServlet);
megaList.addAll(depotDOListServlet);
megaList.addAll(userAuctionRelDOListServlet);

now how do i display this in for each?? would this work? where mega is the name of the variable??

   <td><c:out value="${mega.endDate}"/> </td>

this now hows errors for depot name and bidamt as they are in a totally different DO.. wat to do??

As you did. depotDOListServlet and userAuctionRelDOListServlet are two array lists then same way you can use <c:forEach></c:forEach> to iterate those lists.

<c:forEach var="auctionDO" items="${auctionDOListServlet}">
 <tr div class="odd"> 
  <td style="font-size:14px;"><a href="/myproject/s/PermanentUserAuctionHistoryInner"><c:out value="${auctionDO.auctionName}"/> </a></td>
  <td><c:out value="${auctionDO.endDate}"/>   </td>
  <td><c:out value="${auctionDO.status}"/></td>
  <c:forEach var="depotDo" items="${depotDOListServlet}">
   <td><c:out value="${depotDo.depotName}"/></td>
  </c:forEach>
  <c:forEach var="userAuctionRelDo" items="${userAuctionRelDOListServlet}">
   <td><c:out value="${userAuctionRelDo.bidAmt}"/></td>
  </c:forEach>
 </tr>
</c:forEach>

Remember that for every item in list auctionDOListServlet rest two lists will iterate each time.
