JS 依照元素出現數量排序
同樣是最近遇到的狀況,需要利用陣列內元素出現的數量進行排序,以下為範例程式:
var array = ["1", "2", "4", "5", "2", "4", "2", "3"]; var str = array.toString(); var filter = []; var result = []; document.write("原始陣列:" + array + "<br>"); var get = function (str, tar, arr, tmp) { if (str.indexOf(tar) >= 0) { tmp = str.slice(str.indexOf(tar) + 1); arr.push(tar); get(tmp, tar, arr, tmp); } return arr; } for (i in array) { var elm = []; var tmp; var fstr = filter.join(); if (fstr.indexOf(array[i]) >= 0) { continue; } else { var tmp_arr = get(str, array[i], elm, tmp); result.push(tmp_arr.length + ':' + tmp_arr[0]); filter.push(array[i]); } } result.sort(); result.reverse(); //按照出現次數排序,不刪除重複元素 var finishArray = []; for (index in result) { var show = result[index].split(':'); for (i = 0; i < show[0]; i++) { finishArray.push(show[1]); } } document.write("按出現次數排序,不刪除重複元素:" + finishArray + "<br>"); //按照出現次數排序,刪除重複元素 var finishArray = []; for (index in result) { var show = result[index].split(':'); finishArray.push(show[1]); } document.write("按出現次數排序,刪除重複元素:" + finishArray + "<br>");
輸出結果:
原始陣列:1,2,4,5,2,4,2,3 按出現次數排序,不刪除重複元素:2,2,2,4,4,5,3,1 按出現次數排序,刪除重複元素:2,4,5,3,1
Online casinos have completely transformed the world of gambling, making it more accessible, convenient, and thrilling than ever before. Now, gamblers don’t have to travel to experience the thrill of betting, because online platforms offer everything from classic slots to live dealer games.
The Appeal of Online Gambling
The surge in popularity of online casinos is driven by several factors. A key benefit is that online casinos are available anytime, anywhere. Unlike physical casinos that have operating hours, virtual casinos allow you to play whenever it suits you best.
Another major reason for their popularity is the sheer variety of games. Physical casinos may offer a few hundred games at best, but digital platforms feature thousands. From classic fruit machines to cutting-edge video slots with immersive themes, the choices are practically limitless.

How Online Casinos Keep Players Engaged
One of the biggest draws of online casinos is the generous promotions and bonuses. Signing up usually comes with exciting perks like extra cash or free slot spins. Loyal customers are rewarded with tiered programs, reloading bonuses, and special incentives.
Luck vs. Skill in Online Gambling
Depending on your preferences, you can choose between pure chance games or those where skill makes a difference. Poker, for instance, is a game of skill where experienced players can outplay beginners by reading opponents and making calculated decisions. On the other hand, slot machines and roulette rely entirely on chance, making them ideal for casual players looking for fun and excitement.
How to Gamble Responsibly Online
To ensure a positive experience, it’s vital to play responsibly and within limits. By setting strict financial limits and staying disciplined, players can prevent gambling from becoming a problem. Trustworthy sites encourage responsible play through features like voluntary betting caps and time-out options.
