有沒有想過將數字格式的計算結果轉化為漢字格式的? 有人會問"干嘛要轉, 數字形式不是蠻好嘛", 可是當這個數字很長的時候就不太容易讀出來了吧, 就算是有千分位的分隔符也不易順口說出, 因為這個符號是位英語行方便的, 不是適合我們的讀法. 那就自己寫一個函數來完成這項任務吧.

將下列代碼加到你的網頁里, 通過num2chi()函數的調用就可以實現上述功能了, 快來試一試吧. 為了各位能讀懂這段代碼, 在下特意加入詳細注解, 還請老鳥們不要嫌羅唆, ^_^.

//----------------------FUNCTION BEGIN-----------------------------

//函數名: num2chi()
//叁  數: 一數字

//功  能: 將難讀的長串數字轉為順口讀出的漢字

function num2chi(result) {

var chiresult = "";            //定義返回值叁數chiresult為字符形式
