将c：forEach变量传递给一个jsp：include [英] Passing c:forEach variable to a jsp:include

问题描述

示例：
$

 < c：forEach items =$ {cart.entries}var =entry> 
< jsp：include page =helper.jsp>< / jsp：include> 
< / c：forEach> 
  

里面的helper.jsp我想能够引用变量'entry'。它不断出现空。我想也许有可能有一种方法来增加范围到forEach变量像正常的设置变量一样。

有什么想法？

解决方案

 < c：forEach items =$ {cart.entries}var = 条目 > 
< c：set var =entryFCvalue =$ {entry}scope =request>< / c：set> 
< jsp：include page =helper.jsp>< / jsp：include> 
< / c：forEach> 
  

然后我引用了我的include中的entryFC。不是非常优雅的，但它的工作，所以我想不适应去与它。

I am trying to access some JSTL variables that were set on a JSTL for-loop in an include.

Example:

<c:forEach items="${cart.entries}" var="entry">
 <jsp:include page="helper.jsp"></jsp:include>
</c:forEach>

Inside helper.jsp I want to be able to reference the variable 'entry'. It keeps coming up as 'empty'. I thought maybe there might be a way to add scope to the forEach Variable like you can with normal set variables.

Any ideas?

解决方案

ANSWER: I ended up just having to do this to get it to work.

<c:forEach items="${cart.entries}" var="entry">
<c:set var="entryFC" value="${entry}" scope="request"></c:set>
 <jsp:include page="helper.jsp"></jsp:include>
</c:forEach>

Then i referenced the entryFC in my include. Not very elegant at all but its working so i guess ill go with it.
