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>
