1、获取当前周、上一周、下一周日期

var cells = document.getElementById('monitor').getElementsByTagName('td');
var clen = cells.length;
var currentFirstDate;
var formatDate = function(date){             
var year = date.getFullYear()+'年';
var month = (date.getMonth()+1)+'月';
var day = date.getDate()+'日';
var week = '('+['星期天','星期一','星期二','星期三','星期四','星期五','星期六'][date.getDay()]+')';  
return year+month+day+' '+week;

};

var addDate= function(date,n){

date.setDate(date.getDate()+n);

return date;

};

var setDate = function(date){

var week = date.getDay()-1;

date = addDate(date,week*-1);

currentFirstDate = new Date(date);
for(var i = 0;i<clen;i++){

cells[i].innerHTML = formatDate(i==0 ? date : addDate(date,1));

}

};

document.getElementById('last-week').onclick = function(){

setDate(addDate(currentFirstDate,-7));

};

document.getElementById('next-week').onclick = function(){

setDate(addDate(currentFirstDate,7));

};

setDate(new Date());

2、设置js从周一到周日，而不是从周日到周六：

addDate(date,n){     
            date.setDate(date.getDate()+n);        
            return date;
        },//总入口
        setDate(date){
            this.weekCalendar.weekHeader = [];
            this.weekCalendar.weekBody = [];
            //这个判断是为了抵消添加了7天后currentFirstDate变成了7天后的数据
            if(this.weekCalendar.currentLastDate){
                this.weekCalendar.currentFirstDate = this.weekCalendar.currentLastDate;
            }             
            //注意：周日date.getDay()=0，所以要退6天，就要赋值day=7
            let day = date.getDay();
            if(day == 0){
                day = 7;
            }
            var week = day - 1;
        date = this.addDate(date,week*-1);

        this.weekCalendar.currentFirstDate = new Date(date);

    }         </code></pre>
3、js日期总结：
1、new Date()是获取当前时间，就算你用setDate setMonth了它还是当前时间
如下面例子：
let date = new Date();
       alert(date.pattern('yyyy-MM-dd'))
       date.setDate(1)
       alert(date.pattern('yyyy-MM-dd'))
       date = new Date();
       alert(date.pattern('yyyy-MM-dd'))
2、month 设置setMonth -1或者 +1会出现问题，已经有人遇到 这个问题：
参考1：http://blog.csdn.net/butterfly5211314/article/details/52742295
2：https://yq.aliyun.com/ziliao/69110
暂时解决办法：
setMonth(-1 +1)的同时设置setDate(1)
4、axios结合springMvc总结
1)@H_404_21@ 前台：axios.post(url,params) @H_404_21@ 后台：(@RequestBody Params params)
2)@H_404_21@ 前台：axios.post(url,qs.stringify(params))@H_404_21@ 后台两种：(@RequestParam String paramsOfOne,@RequestParam String paramsOfTwo)@H_404_21@(HttpServletRequest request)String paramsOfOne = request.getParameter("paramsOfOne");
3)@H_404_21@前台：axios.post(url/${id})@H_404_21@后台：（@PathVariable String id）
5、修改json属性名
JSON.parse(JSON.stringify(res_data.menus).replace(/__child_list/gi,"children").replace(/menu_name/gi,"title"));
