复选框用法
<input type="checkbox" name="checkbox" value="a">
<input type="checkbox" name="checkbox" value="b">
<input type="checkbox" name="checkbox" value="c">
<input type="checkbox" name="checkbox" value="d">
以这个为例,复选框的NAME属性都是相同的,这样就创建了一个控件数组,当传回后台时,是把选中的CHECKBOX按顺序用","连接起来,假如我们选中了B和C,那么用
Response.write Request("checkbox")返回的就是b,c
可以使用Split来分离成数组,例如
bb=Split(Request("checkbox"))
for each b in bb
Response.write b
next
这样显示出来的就是选中的CHECKBOX的value了
事例：多向删除！
