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

I was wondering if you ever considered changing the
layout of your blog? Its very well written; I love what youve got to say.
But maybe you could a little more in the way of content
so people could connect with it better. Youve got an awful lot
of text for only having one or two pictures.
Maybe you could space it out better?
