myList.sort(函数(X,Y){
返回x.timestamp - y.timestamp;
})
myList中
是一个JavaScript数组,它支持排序
方法。该方法接受函数作为参数,根据该返回的值进行排序的阵列。
目前,排序算法将把具有最低时间戳第一元素。交换 x.timestamp
和 y.timestamp
如果你想在其他方向上的数组进行排序。
how can i sort this array by timestamp and what is the fastest way (array has many many entries)?
my array
myList = new Array();
myList[0] = {};
myList[0]['title'] = 'I am really new';
myList[0]['timestamp'] = 1317039046;
myList[0]['date'] = '2011-09-26T12:10:46+00:00';
myList[1] = {};
myList[1]['title'] = 'I am the oldest';
myList[1]['timestamp'] = 1315656646;
myList[1]['date'] = '2011-09-10T12:10:46+00:00';
myList[2] = {};
myList[2]['title'] = 'I am older';
myList[2]['timestamp'] = 1316866246;
myList[2]['date'] = '2011-09-24T12:10:46+00:00';
myList[3] = {};
myList[3]['title'] = 'I am old';
myList[3]['timestamp'] = 1316952646;
myList[3]['date'] = '2011-09-25T12:10:46+00:00';
example

myList.sort(function(x, y){
return x.timestamp - y.timestamp;
})
myList
is a JavaScript array, which supports the sort
method. This method accepts a function as argument, which sorts the array according to the returned value.
Currently, the sort algorithm will place the element with the lowest timestamp first. Swap x.timestamp
and y.timestamp
if you want to sort the array in the other direction.
