在上篇文章給大家介紹了JavaScript sort數組排序方法和自我實現排序方法小結，用自己的方法實現了數字數組的排序。

當然,實際運用中,我還是會使用sort方法更加方便.但是,我上一篇博文,僅僅是實現了數字排序,而srot方法默認可是能給字母實現排序的哦!而我的代碼只能排序數字,看起來還是弱弱的.

所以,我得加上能排字母甚至中文的排序方法.

實現代碼

$(function(){var arr = ["Jack","Book","Fung",76,"Love","Mark","中國","china","phone","劉德華"];console.log('原數組');console.log(arr);console.log('for方法從小到大排序');console.log(arrSortMinToMax(arr));console.log('for方法從大到小排序');console.log(arrSortMaxToMin(arr));console.log('原數組');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);}
