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

If you’ve been an online bingo fan for a while, you’ll have heard about no deposit bingo sites. But are there any no deposit bingo bonuses available? And if “yes,” what do you need to claim them? The latest skill-based bingo app has arrived to the Appstore. Bingo King is giving away thousands of dollars to players every single day. Take your chance to win hundreds in real cash prizes when you compete in ad-free bingo competitions. This website is using a security service to protect itself from online attacks. The action you just performed triggered the security solution. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. If you’re wondering how you can find a £15 no deposit bonus – the truth is that you need to act quickly. By this, we mean that £15 free no deposit bingo sites typically have a quota – meaning that they can only offer a certain number of bonuses before the offer expires. This does make sense when you consider that the bingo site is effectively giving away free cash without asking for any payment methods or deposited funds.

• Game 1: Knicks 121, Pacers 117 (Knicks lead series, 1-0) Despite the Knicks’ early lead in the series, Joel Embiid remains confident in Philadelphia’s potential. He has boldly stated that the 76ers will still come out on top. The Knicks are -230 to win on Monday, according to DraftKings. “Even going into tonight’s game, I think he was averaging 30 points against Indiana,” Thibodeau said. “Everyone, we’ve all come to expect him to be super-human every night. And he’s in incredible player. He’s loaded up on every night. He’s the focal point of everyone’s game plan. And sometimes it’s a case of missing shots, and they could be good shots. And so I think we all tend to forget that and the thing I love about his approach is he never gets crazy. He’s like a machine every day, he comes in locked in, this is what he’s going to do, he’ll be ready for the next game.”

The inspiration for one of our favorite kids birthday parties comes from the NBC game show “Minute to Win It” and if you have never seen this show- I’ll summarize it for you. Contestants are given challenges involving common household items to complete in 60 seconds to win ever-increasing prize money. So the first challenge will be the easiest one, and they continue to ramp up in difficulty as contestants work their way up to the ultimate $1 million prize. But the best part is that the challenges are fun (and funny!) and can easily be replicated at home for your very own Minute to Win It Birthday Party! No matter what game you choose, all you need for an escape room game is a printable PDF kit, scissors, and some glue. Place the puzzles around your home and let your kids play. You serve the role of the game master, giving them hints as they progress in the game.
Spot on with this write-up, I absolutely believe that
this website needs a lot more attention. I’ll
probably be returning to see more, thanks for the advice!
Fine way of describing, and nice piece of writing to take facts on the topic of my presentation subject matter,
