複選框
<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">
以這個為例,複選框的NAME屬性都是相同的,這樣就建立了一個控制項數組,當傳回後台時,是把選中的CHECKBOX按順序用","串連起來,假如我們選中了B和C,那麼用
Response.write Request("checkbox")返回的就是b,c
可以使用Split來分離成數組,例如
bb=Split(Request("checkbox"))
for each b in bb
Response.write b
next
這樣顯示出來的就是選中的CHECKBOX的value了
