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

How Nigeria’s biggest city became the world’s hottest winter party destination
casino bonus
It’s a world of endless parties and sleepless nights. A relentless celebration that turns West Africa – and especially Nigeria’s largest city, Lagos – into one of the hottest destinations on the continent, if not the planet, right in the middle of winter.
Detty December is a magical time between December and early January when diaspora communities and tourists flock to Ghana, Nigeria and South Africa for an unforgettable experience filled with flavourful food, soulful African music and sunshine.
Beach parties, festivals and top-tier performances fuel the energy, while fashion takes center stage, with everyone dressing to impress.
Nearly two-thirds of Nigeria’s population is under 25, according to the United Nations Population Fund, making this one of the world’s youngest countries.
Internationally renowned Afrobeats performers and foreign artists make surprise appearances. DJs take to the streets, blasting powerful beats from consoles mounted atop bright yellow minibuses.
At times it’s all-consuming. Good luck getting hair salon appointments, affordable air tickets or navigating Lagos’ already notorious traffic when the party crowds are in town.
Detty December (“detty” is a playful corruption of “dirty”) is a triumphant celebration of culture, music and good vibes that has evolved in recent years during the traditional holidays influx of diaspora returnees, which heightened in 2018 when Ghana ran a launched a successful “Year of Return” campaign actively encouraging people to visit their ancestral homelands.
It’s gathered pace over the past five years, gaining an international reputation, as IJGBs (“I Just Got Backs”) and their friends arrive in batches, eager to unwind and blow off steam after the fast-paced, hard-working year they’ve had overseas.
For many in the vast Nigerian diaspora, it is a deeply personal homecoming, a chance to reconnect with their heritage, traditions and families while immersing themselves in the lively energy of Nigerian life.
