js ArrAy sort

function test(){ var num = 2; var arr = [[1, 1, "a"], [2, 2, "b"], [3, 4, "c"], [4, 2, "d"], [5, 5, "e"]]; var newArr = new Array(), newArr1 = new Array(); for(var i = 0; i < arr.length; i++){ if (arr[i][1] == num){ newArr.push...

javascript的数组有sort方法。按照数值的大小对数字进行排序,必须使用一个排序函数:a代表数组的前一位,b代表数组的后一位。var arr = [1,2,3,5,2,5,3,6,2,6,2,6,2,5,9,6,8,54,3,6,8];arr.sort(function(a,b){return a-b});这样是升序排列。如...

你好,Javascript中的数字数组排序非常简单,JS本身提供了内置的排序方法,直接调用就可以了。 var arr = [1, 20, 49, 32, 43, 69];arr.sort();console.log(arr); // [1, 20, 32, 43, 49, 69]还有一种更加灵活的写法: arr.sort(function(a, b){...

var a=[9,2,33,66,55,56,34,1,91,88];for(var i=0;i

你好,这个问题我这样解决的,你看下: var arr= [ {name:'qqq', num:2,time:'2015-06-08 13:44:18'}, {name:'www', num:3,time:'2015-06-08 13:44:18'}, {name:'eee', num:4,time:'2015-06-07 13:40:18'}, {name:'rrr', num:4,time:'2015-06-08...

var arr = [{ name: 'xx1', time: '1995-05-01', num: 100}, { name: 'xx2', time: '1995-05-02', num: 101}, { name: 'xx3', time: '2001-01-01', num: 200}, { name: 'xx4', time: '2001-05-07', num: 56}];arr.sort(function(a, b) { var at ...

var aa=[ {"time":Date.parse("2017/02/22 16:30"),"val":22}, {"time":Date.parse("2017/02/21 16:30"),"val":11}, {"time":Date.parse("2017/02/23 16:30"),"val":33}, {"time":Date.parse("2017/02/24 16:30"),"val":44} ]; aa.sort(functio...

Array.prototype.unique = function(){this.sort();//先排序var res = [this[0]];for(var i = 1; i < this.length; i++){if(this[i] !== res[res.length - 1]){res.push(this[i]);}}return res;}var arr = [1, 'a', 'a', 'b', 'd', 'e', 'e', 1,...

r.sort(function ma(a,b){ if(ab){return 1; } return 0; });

数组排序,你可以直接调用javascript原生自带的sort()方法,比如下面的例子:// Array.prototype.sort() //原生自带的数组的排序方法;var fruit = ['apples', 'bananas', 'Cherries']; //定义一个数组fruit.sort(); // ['Cherries', 'apples', ...
