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

Yesterday, while I was at work, my sister stole my apple ipad

just so she can be a youtube sensation. My apple ipad is now destroyed and she
has 83 views. I know this is totally off topic but I had to share
it with someone!

Whether or not misconduct is actionable under Title IX, it may possibly be actionable less than an additional component of a recipient’s code of conduct ( e.g., anti-bullying). The Department understands that analysis shows that rape victims usually do not report owing to misconceptions about what rape is ( e.g., a false impression that rape should include violence inflicted by a stranger), and that rape victims may well decrease their individual working experience and not report sexual assault, for a quantity of explanations. The Department understands commenters’ problems that this suggests that only “the most severe” harassment situations will be investigated and that complainants will come to feel deterred from reporting non-sexual assault harassment due to questioning if the harassment is “bad enough” to be protected under Title IX. Another commenter expressed worry that schools would have far too a great deal discretion to decide whether conduct was severe, pervasive, and offensive and this will guide to arbitrary selections to turn absent reporting parties. A couple of commenters asserted that courts have uncovered some undesired sexual conduct (for instance, a supervisor forcibly kissing an employee) is not extreme and pervasive even though this sort of actions may perhaps represent legal assault or battery underneath State regulations and that a definition of sexual harassment ought to at minimum deal with misconduct that would be regarded criminal.
