[英]How can I get the value of element which inside of an Arralyst in my JSP with JSTL tag?
I wanted to get the value of each element which are inside of ArrayList which has been passed to JSP as a request.setAttribute. 我想获取ArrayList内每个元素的值,该元素已作为request.setAttribute传递给JSP。
When i write the next code I can get the value of each element wihtin the ArraList: 当我编写下一个代码时,我可以通过ArraList获得每个元素的值:
<table border="1">
<c:forEach var="item" items="${ListCompanies}">
<td><b><c:out value="${item.string2}"/></b></td>
<td><b><c:out value="${item.string3}"/></b></td>
</c:forEach>
</table>
However, I dont know how i can get the value directlly, with out foreach operation 但是,我不知道如何在没有foreach操作的情况下直接获得价值
Something like that: 像这样:
<c:out value="${ListCompanies.string2}"/>
Could somebody tell me how can I manage c:out to get value from elements? 有人可以告诉我如何管理c:out以从元素中获取价值吗?
Something like 就像是
<c:out value="${ListCompanies[0].string2}" />
OR 要么
<c:out value="${ListCompanies[1].string3}" />
