timeDate.js 插件优化

昨天写的时候，在下面代码处就碰到了问题，

如下：

if(data.zero) {
　　if(data.Month_zero) {
   　　if(time.month < 10) {
       　　time.month = "0" + time.month;
       }
    }
    if(data.Day_zero) {
       if(time.day < 10) {
           time.day = "0" + time.day;
       }
    }
    if(data.Hours_zero) {
       if(time.hours < 10) {
           time.hours = "0" + time.hours;
       }
    }
    if(data.Min_zero) {
       if(time.minutes < 10) {
           time.minutes = "0" + time.minutes;
       }
    }
    if(data.Second_zero) {
      　if(time.seconds < 10) {
           time.seconds = "0" + time.seconds;
        }
    }
}

因为代码耦合程度太高，所以想用一个函数来封装，如下：

function Zero(a) {
    if(a < 10) {
        a = "0" + a;
    }
}    

却无法让其改变原始的参数值，挣扎了许久，就放下了。

今天经过一天的征战，终于得以解决。源码如下：

好，优化完成。
