如果再有县等,那么就把县放到一个二维数组,二维数组的第一维和选中的市相对应,然后操作思想和上面相同
关于常规思路清空上次所有的OPTION:
//本想用WITH语句偷懒,没想到引发BUG
WITH(SELCITYNODE){
IF(OPTIONS.LENGTH>1){//除了"选择"OPTION
VAR LENGTH=OPTIONS.LENGTH;//OPTIONS.LENGTH在REMOVE的过程中时刻在变化
//删除的个数(次数:删除LENGTH-1次)是不变的
FOR(VAR I=1;I<LENGTH;++I)
OPTIONS.REMOVE(1);
}
}
ALERT("LENGTH="+SELCITYNODE.OPTIONS.LENGTH);//3 //测试语句,以上使用WITH语句后,集合中的引用不能删除成功
