说明： 是 上 一 回 程 式 的 改 进 版！
本程式支持排序，shift和ctrl功能！（即：连选和跳选多项option）
可以任意的相互操作（下拉列表框1<=>下拉列表框2）！
如果多维数组复杂，可以自己写一个排序函数！
javascript中sort()所传的参数为数组的俩个record(我的定义),默认按
字符排序。
排序所传的参数也为一个数组，例数组a 为下所示：
a[0][0]=1;
a[0][1]=2;
a[0][2]=3;
a[0][3]=4;
a[1][0]=1;
a[1][1]=2;
a[1][2]=3;
a[1][3]=4;
a[2][0]=1;
a[2][1]=2;
a[2][2]=3;
a[2][3]=4;
每次所传的参数为下：
a[0]={1,2,3,4}
a[1]={1,2,3,4}
。。。。。。。
那么自己根据要求就可以对传来的参数数组（实际为数组中的record）
中的某一个field进行排序！
