session问题？

[xuehuajian]

session("a")里面是1,2,5,7,9......等内容
现在我想去掉当中一个跟接收过来相同的数字，应该怎么去掉

[stefli]

<%
thearr = session("a")
arr = split(thearr,",")
for i= lbound(arr) to ubound(arr)
thevalue = arr(i)
if request("b")=thevalue then
thevalue=""
end if
next

%>
好象不能删除，我现在只能想到这里了。

session = replace(session("a"),",你想代替的东西")

[不老书生]

replace(session("a"),",9,",",")

即把1,9,12 ----> 1,12

呵。。。。。。。。。。一个简循环。

我就不再贴了！

[xiaobird1]

<%
Session("a") = "1,2,3,4,5,6,7,8,9"
Response.write "Session(a): " & Session("a") & "<br>"
Response.write "Deleted: " & DelString(Session("a"),"2")

function DelString( yStr, delStr )
dim i
dim szTmp1, szTmp2
i = instr(yStr, delStr)

szTmp1 = left(yStr,i-1)
szTmp2 = mid(yStr,i+2)

DelString = szTmp1 & szTmp2
end function
%>

replace(session("a"),",9,",",")

即把1,9,12 ----> 1,12

如果去掉的是第一个数字和最后个数字呢，那不得重新写
应该是用下面的循环

for i= lbound(arr) to ubound(arr)
thevalue = arr(i)
if request("b")=thevalue then
thevalue=""
end if
next
但是不知道怎么去掉，谁有办法阿？

不用循环啦

Number=trim(request("Number"))

session("a")=replace(replace(session("a"),Number&",",""),","&Number,"")

肯定可以的，试试：）

[xuehuajian]

不用循环啦

Number=trim(request("Number"))

session("a")=replace(replace(session("a"),Number&",",""),","&Number,"")

肯定可以的，试试：）
是个办法，还有别的办法嘛？

[avonqin]

有！

[xuehuajian]

有给段代码阿~~~

Number=trim(request("Number"))

session("a")=replace(replace(session("a"),Number&",",""),","&Number,"")

上面还缺了一步，删除不掉剩下的最后一个：）
session("a")=replace(replace(replace(session("a"),Number&",",""),","&Number,""),number,"")

不知道这样执行效率怎么样？
