排序完了不知道要返回数组还是对象,先这样吧
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>object</title></head><body><script>function myArray() {this.length = arguments.length;this.arr = []for (var i = 0; i < this.length; i++) {this[i] = arguments[i];this.arr[i] = arguments[i]; //也可以把数组转到一个单独的属性里去操作}this.sort = function (order = false) {if(typeof order == 'function'){var a = this.arr[0];var b = this.arr[1];order = order(a, b) > 0 ? true : false;}for (var i = 0; i < this.length; i++) {for (var j = 0; j < this.length - 1 - i; j++) {if (order) {if (this[j] < this[j + 1]) {var min = this[j];this[j] = this[j + 1];this[j + 1] = min;}} else {if (this[j] > this[j + 1]) {var max = this[j];this[j] = this[j + 1];this[j + 1] = max;}}}}return this;}this.reverse = function () {var arrReversed = [];var j = 0;for (var i = this.length - 1; i >= 0; i--) {arrReversed[j] = this[i];j++;}return arrReversed;}this.max = function () {var max = this[0];for (var i = 1; i < this.length; i++) {if (this[i] > max) {max = this[i];}}return max;}this.min = function () {var min = this[0];for (var i = 1; i < this.length; i++) {if (this[i] < min) {min = this[i]}}return min;}this.shift = function () {var temp = this[0];this.length--;for (var i = 0; i < this.length; i++) {this[i] = this[i + 1]}delete this[this.length];return temp;}}var arrObj = new myArray(1, 3, 5, 7, 2, 4, 6, 8);var sortedArr = arrObj.sort(function (a, b) {return a - b;})console.log(sortedArr);console.log(arrObj.reverse());console.log(arrObj.max());console.log(arrObj.min());</script></body></html>
