在JSTL / EL中表示一个简单的for循环 [英] Representation of a simple for loop in JSTL/EL

问题描述

我需要在JSTL / EL中为循环（在Java上下文中）表示下面的。

<$ p $ （int i = 6; i< = 15; i ++）{
System.out.print（i +\ t）;



$ b $ p
$ b $ p








$ b

  6 7 8 9 10 11 12 13 14 15 
  

我如何在JSTL / EL中做同样的事情？我对此没有确切的想法。

 < c：forEach begin =6end =15varStatus =环> 
< c：out value =$ {loop.count}/> 
< / c：forEach> 
  

显然会显示以下输出。

  1 2 3 4 5 6 7 8 9 10 
  

这不是我想要的。我需要在 6 和 15 之间显示数字（即在指定范围之间）。我需要把这样一个概念来实现分页在我的Web应用程序。我可以用EL做这个吗？

\t in这个语句 System.out.print（i +\ t）; 不重要。

解决

 < c：forEach begin =6end =方案

15var =val>
< c：out value =$ {val}/>
< / c：forEach>


或以下内容：

 < c：forEach begin =6end =15varStatus =loop> 
 < / c：forEach> 
  

或以下内容：

 < c：forEach begin =6end =15varStatus =loop> 
< c：out value =$ {loop.index}/> 
< / c：forEach> 
  

I need to represent the following for loop (in Java context) in JSTL/EL.

for (int i = 6; i <= 15; i++) {
  System.out.print(i+"\t");
}

It would display the following output.

6      7      8       9       10       11       12       13       14       15

How can I do the same in JSTL/EL? I have no precise idea about it. I'm just trying the following.

<c:forEach begin="6" end="15" varStatus="loop">
    <c:out value="${loop.count}"/>
</c:forEach>

and it would obviously display the following output.

1 2 3 4 5 6 7 8 9 10 

It's not that I want. I need to display numbers between 6 and 15 (i.e between the specified range). I need to put such a concept to implement paging in my web application. Can I do this using EL?

\t in this statement System.out.print(i+"\t"); is not significant.

解决方案

The following should work:

<c:forEach begin="6" end="15" var="val">
    <c:out value="${val}"/>
</c:forEach>

Or the following:

<c:forEach begin="6" end="15" varStatus="loop">
    <c:out value="${loop.current}"/>
</c:forEach>

Or the following:

<c:forEach begin="6" end="15" varStatus="loop">
    <c:out value="${loop.index}"/>
</c:forEach>
