按单键用日期值对对象数组进行排序

您可以使用

Array.sort

这是一个例子：

var arr = [{    "updated_at": "2012-01-01T06:25:24Z",    "foo": "bar"  },  {    "updated_at": "2012-01-09T11:25:13Z",    "foo": "bar"  },  {    "updated_at": "2012-01-05T04:13:24Z",    "foo": "bar"  }]arr.sort(function(a, b) {  var keyA = new Date(a.updated_at),    keyB = new Date(b.updated_at);  // Compare the 2 dates  if (keyA < keyB) return -1;  if (keyA > keyB) return 1;  return 0;});console.log(arr);
