这个js,看不懂了,定义了showYear,为什么页面显示是2016年呢?前面为何还要定义呢??

var calUtil = {
//当前日历显示的年份
showYear:2015,
//当前日历显示的月份
showMonth:12,
//当前日历显示的天数
showDays:5,
eventName:"load",
//初始化日历
init:function(signList){
calUtil.setMonthAndDay();
calUtil.draw(signList);
calUtil.bindEnvent();
},
draw:function(signList){
//绑定日历
var str = calUtil.drawCal(calUtil.showYear,calUtil.showMonth,signList);
$("#calendar").html(str);
//绑定日历表头
var calendarName=calUtil.showYear+"年"+calUtil.showMonth+"月";
$(".calendar_month_span").html(calendarName);

},
//绑定事件
bindEnvent:function(){
// //绑定上个月事件
// $(".calendar_month_prev").click(function(){
// //ajax获取日历json数据
// var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"},{"signDay":"13"}];
// calUtil.eventName="prev";
// calUtil.init(signList);
// });
// //绑定下个月事件
// $(".calendar_month_next").click(function(){
// //ajax获取日历json数据
// var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"}];
// calUtil.eventName="next";
// calUtil.init(signList);
// });
},
//获取当前选择的年月

已采纳

calUtil.showYear=current.getFullYear();
这里又绑定了一次,去掉

caozhy 回复拼图_: 你可以不定义。因为你后面初始化了一次。也可以在前面写。这是灵活的。
