有沒有想過將數(shù)字格式的計算結(jié)果轉(zhuǎn)化為漢字格式的? 有人會問"干嘛要轉(zhuǎn), 數(shù)字形式不是蠻好嘛", 可是當這個數(shù)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(shù)來完成這項任務(wù)吧.

將下列代碼加到你的網(wǎng)頁里, 通過num2chi()函數(shù)的調(diào)用就可以實現(xiàn)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, ^_^.

將下面這兩條語句放到script塊中試運行一下看看結(jié)果對不對, 另外可以訪問我的主頁http://dreamer.oso.com.cn 在休閑廣場里有一個彩票頁面, 就是用這段代碼實現(xiàn)的, 歡迎光臨.
