JS 陣列排序範例

馬老師離開待了約十幾年的教學界,目前在外商科技公司擔任Senior Consultant的工作,原因當然很多,未來有空再慢慢發文章分享,剛好最近有點時間,怕以後忘記,把最近專案中用到的一些程式筆記下來,如果大家有需要,也可以參考使用,這一篇是關於Javascript陣列排序的部分。

通常若有較多的內容需要儲存,變數就沒有陣列來的好用,所以陣列是拿來儲存大量的資料時所使用的,且儲存在裡面的資料,還可以選擇經過排序之後再呈現至畫面上,例如:

var name = ["stanley", "jack", "anita" , "mary"];

name.sort() //依照字母排序
console.log(name); // 輸出 ["anita", "jack", "mary", "stanley"]

names.reverse() //反轉陣列內容
console.log(name); //輸出 ["stanley", "mary", "jack", "anita"]

但若我們同時有多個陣列,但希望以其中之一的內容排序時,也可以同步更新到另外一個陣列,該如何處理呢?可以參考以下的方式:

var name = ["stanley", "jack", "anita" , "mary"];
var gender = ["male" , "male" , "female" , "female"];
var score = [30, 10, 40 , 80];
var ID = ["S1" , "S2" , "S3" , "S4"];

console.log("name : " + name + "; score : " + score + "; gender : " + gender + "; ID : " + ID);
/*
排序前
name : stanley,jack,anita,mary;
score : 30,10,40,80;
gender : male,male,female,female;
ID : S1,S2,S3,S4;
*/

var list = [];
for (var i = 0; i < name.length; i++){
  list.push({
    'name': name[i],
    'score': score[i],
    'gender': gender[i],
    'ID': ID[i]
  });
}

list.sort(function(a, b) {
  return ((a.name < b.name) ? -1 : ((a.name == b.name) ? 0 : 1));
});

for (var i = 0; i < list.length; i++) {
  name[i] = list[i].name;
  score[i] = list[i].score;
  gender[i] = list[i].gender;
  ID[i] = list[i].ID;
}

console.log("name : " + name + "; score : " + score + "; gender : " + gender + "; ID : " + ID);
/*
排序後
name : anita,jack,mary,stanley;
score : 40,10,80,30;
gender : female,male,female,male;
ID : S3,S2,S4,S1;
*/

若是希望按照分數排序,則可以將sort function 修改為下:

//score 由小到大
list.sort(function(a, b) {
  return a.score - b.score
});

//score 由大到小
list.sort(function(a, b) {
  return b.score - a.score
});

補充:

上述的排序內容均以英文和數字為主,若是遇到中文可使用localeCompare進行,而排序的方式是漢語拼音順序,以下為範例:

var arr = ["二","五","四","一","三"];
//漢語拼音:一[yi], 二[er], 三[san], 四[si], 五[wu]
console.log("排序前:" + arr); // 排序前:二,五,四,一,三
arr.sort(function(a,b){
	return a.localeCompare(b, 'zh'); //排序後:二,三,四,五,一
});
console.log("排序後:" + arr); 

var arr = ["中文","英語","法國話", "京片子", "中國"];
//中文[zhong wen], 英語[ying yu], 法國話[fa guo hua], 京片子[jing pian zi], 中國[zhong guo]
console.log("排序前:" + arr); //排序前:中文,英語,法國話,京片子,中國
arr.sort(function(a,b){
	return a.localeCompare(b, 'zh');
});
console.log("排序後:" + arr); //排序後:法國話,京片子,英語,中國,中文


var arr = ["中文","英语","法国话", "京片子", "中国"];
console.log("排序前:" + arr); //排序前:中文,英语,法国话,京片子,中国
arr.sort(function(a,b){
	return a.localeCompare(b, 'zh');
});
console.log("排序後:" + arr); //排序後:法国话,京片子,英语,中国,中文

    I’m impressed, I have to admit. Seldom do I come across a blog that’s both equally educative and entertaining, and without a doubt, you’ve hit the nail on the head. The issue is something which too few people are speaking intelligently about. Now i’m very happy I stumbled across this during my hunt for something concerning this.

  8. Very nice write-up. I certainly appreciate this site. Keep it up!

  11. Next time I read a blog, I hope that it doesn’t disappoint me as much as this one. I mean, Yes, it was my choice to read through, but I really thought you would have something interesting to talk about. All I hear is a bunch of crying about something you could possibly fix if you were not too busy looking for attention.
