javascript 对象数组根据对象object key的值排序

有个js对象数组 var ary=[{id:1,name:"b"},{id:2,name:"b"}] 需求是根据name 或者 id的值来排序,这里有个风骚的函数

函数定义:

</pre><pre name="code" class="html">function keysrt(key,desc) {
  return function(a,b){
    return desc ? ~~(a[key] < b[key]) : ~~(a[key] > b[key]);
  }
}




var ary=[{id:1,name:"b"},{id:2,name:"b"}];


ary.sort(keysrt("name",true));


ary.sort(keysrt("name",false));


ary.sort(keysrt("id",false));
