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

Hemp Seed Oil Combo: Rich formulated full spectrum CBD crafted with hemp seed
oil and cannabidiol. However, Highland Pharms CBD Hemp Oil products receive only Full Spectrum CBD
Extract. Went to meet my boyfriend’s parents for
the first time the other day and took a dropper full
of the 500mg peppermint oil. If your order is placed
after this cut-off, your order will be shipped
the next day. I have been taking this CBD oil in the mornings right after I wake up
and it’s given me a nice emotional boost to start the day.
I have tried a lot of CBD brands and nothing calms me
as this CBD oil does. Shop products from small business brands
sold in Amazon’s store. If you want the goodness of organic coconut MCT oil (carrier oil) and hemp oil,
you should order from CBDFx which is one of the best brands on the
market right now. Our topical CBD cream is formulated
with several deeply nourishing plant-based skin nutrients – like Happy Hemp CBD Reviews oil,
shea butter and jojoba seed oil – to help relieve dry skin, plus a blend of nutrient-rich plant botanicals to support the appearance
and feel of smooth, healthy skin.
