Question

ASP 数组相加

如何让表内相加？需要输出总和：10
我用
<%price = rs("price")
pprice = Split(price,",")
Amout=0
for i=0 to UBound(pprice)
Amout=Amout+pprice(i)
Response.Write ""&pprice(i)&""
Next%>

这段语句，相加是3+4=7，而不是1+2+3+4=10!

Answer 1

<%price = rs("price")
pprice = Split(price,",")
Amout=0 '问题出在这里,如果你外层还有循环,比如执行rs.movenext后再回到这里,就把原来相加的值清零了,把这个放到外层循环以外就行了.
for i=0 to UBound(pprice)
Amout=Amout+pprice(i)
Response.Write ""&pprice(i)&""
Next%>

如
Amout=0 '在这里
Do Until rs.Eof
price = rs("price")
pprice = Split(price,",")
for i=0 to UBound(pprice)
Amout=Amout+pprice(i)
Next
rs.MoveNext
Loop
Response.Write Amout

Answer 2

<%price = rs("price")
pprice = Split(price,",")
Amout=0
for i=0 to UBound(pprice)
Amout=Amout+pprice(i)

Next
Response.Write ""&pprice(i)&""
%>
这样就可以了
