JS问题笔记

一、JS集合对象值的解析

       初始化JS集合对象objectList: {"1":1,"2":3,"3":5,"4":7,"5":9,"6":11}，解析objectList(key,value)，对应key的value取值范围为当前值(包含当前值)到下一等级的初始值。

var objectList;
function validateGrades(){
    var level = $("#level").val(); //获取到等级区间
    var clickPoints = $("#hitCount").val(); //获取到奖励金额
    var nextGrade = parseInt(level)+1;
    for (var key in objectList) {
        if(key == nextGrade){
            if(clickPoints >= objectList[key]){
                alert("奖励金额大于最大值");
                return false;
            }
        }
        if(key == parseInt(level)){
            if(clickPoints<objectList[key]){
                alert("奖励金额小于初始值");
                return false;
            }
        }
    }
    return true;
}
