楼主最近遇到一个要在js中写多条件的条件判断语句其中有个条件是类似于这种0<${aphot.count}<=5,楼主一开始是这么写的但是只进入第一个和最后一个
<c:forEach items="${listAp}" var="aphot"> alert("ap信息==>"+${aphot.id}+":"+${aphot.count}); <c:if test="${aphot.count == 0}"> alert("等于0"); </c:if> <c:if test="${aphot.count>0} && ${aphot.count<=5}"> alert("0-5 :"+${aphot.xValue}+","+${aphot.yValue}); </c:if> <c:if test="${aphot.count>5} && ${aphot.count<=10}"> alert("5-10:"+${aphot.xValue}+","+${aphot.yValue}); </c:if> <c:if test="${aphot.count >10}"> alert("10以上:"+${aphot.xValue}+","+${aphot.yValue}); </c:if> </c:forEach>
最后改成这样子每个条件都可以进去,后来发现像这种语句只用写一个“${}”符号,然后再一个里面做判断就行。
<c:forEach items="${listAp}" var="aphot"> alert("ap信息==>"+${aphot.id}+":"+${aphot.count}); <c:if test="${aphot.count == 0}"> alert("等于0"); </c:if> <c:if test="${aphot.count>0 && aphot.count<=5}"> alert("0-5 :"+${aphot.xValue}+","+${aphot.yValue}); </c:if> <c:if test="${aphot.count>5 && aphot.count<=10}"> alert("5-10:"+${aphot.xValue}+","+${aphot.yValue}); </c:if> <c:if test="${aphot.count >10}"> alert("10以上:"+${aphot.xValue}+","+${aphot.yValue}); </c:if> </c:forEach>
