el表达式 if else

Question

jsp模板标签,有if else的写法吗?

网上查了说这样写

刚学java,确定下只能这样写吗?感觉好别扭!

或者说有没有其他写法,

如果只有这样的写法,

那么

if(){

}elseif(){

}elseif(){

}

这样的情况怎么表示?

Answer 1

这样表示&nbsp;<c:choose>&nbsp; &nbsp; <c:when test="${1==2}">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0001&nbsp; &nbsp; </c:when>&nbsp; &nbsp; &nbsp; &nbsp;<c:otherwise>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <c:choose>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <c:when test="${1==3}">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0002&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</c:when>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <c:otherwise>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0003&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</c:otherwise>&nbsp; &nbsp; &nbsp; &nbsp; </c:choose>&nbsp; &nbsp; &nbsp;</c:otherwise></c:choose>

Answer 2

&nbsp; if(){&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; }elseif(){&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; }elseif(){&nbsp; &nbsp; }这种模式不就是3个c:if么
