1.普通数组排序 

  var arr = [3,1,2,4,5,6,8,0,1];

//自定义排序规则
function
compareTo(object1,object2){
  if(object1 < object2){
    return -1;
  }else if(object1 > object2){
    return 1;
  }else{
    return 0;
  }
} 
arr.sort(compareTo);
结果[0, 1, 1, 2, 3, 4, 5, 6, 8]

 

2:对象数组中,根据某一属性对数组对象排序

  var arr = [{name:'张三',age:23},{name:'李四',age:24},{name:'王五',age:25}];

function createComparator(property){
    return function (object1,object2){
        var value1 = object1[property];
        var value2 = object2[property];
        if(value1 < value2 ){
            return -1;
        }else if(value1> value2 ){
            return 1;
        }else{
            return 0;
        }
    }
}   
arr.sort(createComparator("name"));
结果:[
{name: "张三", age: 23},{name: "李四", age: 24},{name: "王五", age: 25}]
