          //這里面主要是由于銀聯的手機支付用到了一個付款的轉換方式問題，當調用支付寶付款的時候，比如一分錢格式就是我們普通用的格式：0.01，而銀聯確要把格式轉化為000000000001（銀聯要求是12位）這種格式的，最后一位是分，然后向前依次是角，元，十元，百元，相信不用我說，你已經懂了吧。所以這里就需要一個轉換，為了應對像1000，1000.00，1000.0這種傳過來的格式的數據，特做一下轉換，然后傳給銀聯進行支付。

          如果需要將復選框選中的值操作，可在循環里面加字符串拼接，每個用逗號隔開，在js里頁面跳轉，憑借的字符串如果是數組，作為url傳遞的參數，接手后不是數組，是字符串形式的，只要用函數分割就ok了。
