js时间格式化（年月日星期时分秒）

function timeWeekFormat(times){
    //定义一个日期对象;
    var dateTime=new Date(times);
    //获得系统年份;
    var year=dateTime.getFullYear();
    //获得系统月份;
    var month=dateTime.getMonth() + 1;
    //获得系统当月分天数;
    var day=dateTime.getDate();
    //获得系统小时;
    var hours=dateTime.getHours();
    //获得系统分钟;
    var minutes=dateTime.getMinutes();
    //获得系统秒数;
    var second=dateTime.getSeconds(); 
    //获得系统星期几;
    var dayCycle=dateTime.getDay();
    //使用数组更改日期样式;
    var dayCycleArray=["日","一","二","三","四","五","六"];
    for(var i=0;i<7;i++){
        if(dayCycle==i){
           //将dayCycleArray的数赋值到系统星期几里面中去;
            dayCycle=dayCycleArray[i];
        }
