假設前面表單傳來了
<input name="id" type="hidden" value="1" />
<input name="id" type="hidden" value="1" />
<input name="id" type="hidden" value="2" />
<input name="id" type="hidden" value="3" />
<input name="id" type="hidden" value="3" />
<input name="id" type="hidden" value="2" />
<input name="id" type="hidden" value="3" />
接收端這邊怎麼下可以得出
id = 1 amount: 2
id = 2 amount: 2
id = 3 amount: 3

最佳解答

&lt;pre class="c" name="code">
ReDim C(3)

for each item in Request("id")
	C(item) = C(item) + 1
next

for each x in C
	Response.Write "id=" & x & ",amount:" & C(x)
next

最後這樣搞定

&lt;pre class="c" name="code">
Dim ValName, ValSection, d
Set d = Server.CreateObject("Scripting.Dictionary")
ValName = Split(Request("visitor_name"), ",")
ValSection = Split(Request("visitor_section"), ",")

For I = 0 To Ubound(ValName)
	Section = Trim(ValSection(I))
	If d.Exists(Section) Then
		n = d.Item(Section)
		n = n + 1
		d.Item(Section) = n
	Else
		d.Add Section, 1
	End If
Next

dk = d.keys
di = d.items

For J = 0 To d.Count-1
	Response.Write(dk(J)&"共有"&di(J)&"個&lt;br />")
Next
