[JS]: 数组排序，根据key删除record

1. Array sort()
   – To sort “xxx” first, the second is “yyy”

var arr = [];
arr.push({
  "xxx":"xx",
  "yyy":"yy",
  "zzz":"zz"
});
arr.sort(function(a,b){
  if(a.xxx === b.xxx){
    return a.yyy >= b.yyy ? 1 : -1;
  }
  return a.yyy >= b.yyy ? 1:-1;
});

1. Object Array (JSON) delete by key

var persons = [];
var person={name:"yaoMing",sex:"m",age:"26"};
persons.push(person);  //数组最后加一条记录
persons.unshift(person);  //数组最前面加一条记录
persons.pop();//删除最后一项
persons.shift();//删除第一项

//删除
persons.splice(0,1);//开始位置,删除个数
//替换不删除
var self={id:"001",name:"tom",sex:"m",age:"24"};
var brother={name:"Mike",sex:"m",age:"29"};
persons.splice(1,0,self,brother);//开始位置,删除个数,插入对象
//替换并删除
var self={id:"002",name:"tom",sex:"m",age:"24"};
var brother={name:"Mike",sex:"m",age:"29"};
persons.splice(id:"003",0,1,self,brother);//开始位置,删除个数,插入对象

// 根据key删除
var delID = "002";
for(var index = persons.length - 1; index >= 0; index--){
  if(persons[index].id === delID || persons[index].id === ""){
    persons.splice(index,1);
  }
}

  var minutes = date.getMinutes();
  var seconds = date.getSeconds();

        (month < 10 ? "0" + month : month) + "-" + year + " " +
        (hour < 10 ? "0" + hour : hour) + ":" +

        (seconds < 10 ? "0" + seconds : seconds);
