在上篇文章给大家介绍了JavaScript sort数组排序方法和自我实现排序方法小结，用自己的方法实现了数字数组的排序。

当然,实际运用中,我还是会使用sort方法更加方便.但是,我上一篇博文,仅仅是实现了数字排序,而srot方法默认可是能给字母实现排序的哦!而我的代码只能排序数字,看起来还是弱弱的.

所以,我得加上能排字母甚至中文的排序方法.

实现代码

$(function(){var arr = ["Jack","Book","Fung",76,"Love","Mark","中国","china","phone","刘德华"];console.log('原数组');console.log(arr);console.log('for方法从小到大排序');console.log(arrSortMinToMax(arr));console.log('for方法从大到小排序');console.log(arrSortMaxToMin(arr));console.log('原数组');console.log(arr);});function arrMinNum(arr){var minNum = Infinity, index = -1,minVul = "";for (var i = 0; i < arr.length; i++) {if (typeof(arr[i]) == "string") {if (arr[i].charCodeAt()<minNum) {minNum = arr[i].charCodeAt();minVul = arr[i];index = i;}}else {if (arr[i]<minNum) {minNum = arr[i];minVul = arr[i]index = i;}}};return {"minNum":minVul,"index":index};}function arrSortMinToMax(arr){var arrNew = [];var arrOld = arr.concat();for (var i = 0; i < arr.length; i++) {arrNew.push(arrMinNum(arrOld).minNum);arrOld.splice(arrMinNum(arrOld).index,1)};return (arrNew);}function arrMaxNum(arr){var maxNum = -Infinity, index = -1,maxVul = "";for (var i = 0; i < arr.length; i++) {if (typeof(arr[i]) == "string") {if (arr[i].charCodeAt()>maxNum) {maxNum = arr[i].charCodeAt();maxVul = arr[i];index = i;}}else {if (arr[i]>maxNum) {maxNum = arr[i];maxVul = arr[i];index = i;}}};return {"maxNum":maxVul,"index":index};}function arrSortMaxToMin(arr){var arrNew = [];var arrOld = arr.slice(0);for (var i = 0; i < arr.length; i++) {arrNew.push(arrMaxNum(arrOld).maxNum);arrOld.splice(arrMaxNum(arrOld).index,1);};return (arrNew);}

运行截图如下:
