Trailing zero 尾隨零，是與 Leading zero 前導零 完全相反的概念，是在數字後面補0，詳細可以看維基百科的解說，具體用法如下
直觀的對比就如下：
| 一般數字 | 經過 Trailing zero 處理 |
|---|---|
| 123 | 123000000 |
| 44444 | 444440000 |
| 5566666 | 556666600 |
| 7890 | 789000000 |
| 9876543 | 987654300 |
JS 數字後面補0
Trailing zero的概念是沒有滿足長度時，往後面補0，可以直接照下面這樣做。
// 數字、字串後補0
// code : 你輸入的資料(字串、數字)
// dataLength : 資料補0後的長度
function TrailingZero( code, dataLength){
var str = code + Array(10).join('0');
return str.slice(0 , dataLength)
}
var str = 'abc123'
console.log(TrailingZero(str , 10))
// output : 'abc1230000'同樣，你可以在後面加上任何你想加的符號，直接把 join()中的0，改成你希望補的代號就可以了。
相容 IE 老系統
如果你是串接很老的系統，比方說對方還是使用 IE 開啟，可以更換為以下代碼：
// input: (123 , 8) , output : 12300000
function TrailingZero( code, dataLength){
var str = code + '0000000000';
return str.slice(0 , dataLength);
}
var str = 'abc123'
console.log(TrailingZero(str , 10))
// output : 'abc1230000'
