Web programmer take a look please. Thank you very much. Array can't be converted into number?

本文发表在 rolia.net 枫下论坛Hi,freinds. I write a simple code as following:
----------------------------------------------
<%
dim col1(2)
col1(1)=TRIM(Request("col1(1)"))
col1(2)=TRIM(Request("col1(2)"))
col1(1)=cINT(col1(1))
col1(2)=cINT(col1(2))
total1=col1(1)+col1(2)

%>
<html>
<body>
<%=col1(1)%><br>
<%=col1(2)%><br>
<%=total1%><br>
</body>
</html>
-----------------------------------------------
It works. When I input 2 number in the table of another webpage, it gives right answer.
But because the involved row is actually much larger than 2. So I want to use FOR looping
to simplize the code. I write as following:
------------------------------------------
<%
dim col1(2)
col1(0)=0
for i=1 to 2
col1(i)=TRIM(Request("col1(i)"))
col1(i)=cINT(col1(i))
total1=col1(i)+col1(i-1)
next
%>
<html>
<body>
<% for i=1 to 2%>
<%=col1(i)%>
<%next%>
<%=total1%>
</body>
</html>
---------------------------
But it doesn't work.IE displays:"Type mismatch: 'cINT' "Who can tell me how to fix it?
Thanks a lot.更多精彩文章及讨论，请光临枫下论坛 rolia.net

    • 感觉想数组溢出了，dim col(2)好象只有col(1) 和col(0)，没有col(2)的 -hugefox(长得象熊的狐狸); 2002-6-17 (#582569@0)
      • You are wrong. Dim col1(2) has 3 variable3 col1(0),col1(1),col1(2). -waokool(waokool); 2002-6-17 (#582865@0)
    • 俺没用过ASP，不过你这错误倒也明显 -xanada(㊣流水); 2002-6-17 {173} (#582578@0)
      就是既然定义了dim col1(2)，就说明只有两个元素喽。但是你又接着写col1[0]=0, col1[1]=x, col1[2]=y, 当然就不对啦。想求和，在for外面定义一个sum=0; 然后在for里面sum+=col1[i]即可。
    • the problem is col1(i)=TRIM(Request("col1(i)")) -hainan(hainan); 2002-6-17 {60} (#582596@0)
      you should use
      col1(i)=TRIM(Request("col1(" & i & ")"))
      • good try. But it doesn't work. I think problem occurs in the data type within the cINT. It looks like cINT (clo1(i)) is wrong accroding to the IE response. -waokool(waokool); 2002-6-17 (#582877@0)
    • the array index is begin from 0. So you don't have col1(2). -benbendan(笨笨蛋); 2002-6-17 (#582651@0)
      • the definition of C and VB is different. -hainan(hainan); 2002-6-17 (#582656@0)
    • you look like a girl programmer -rootbear(啤酒); 2002-6-17 {824} (#582814@0)
      <%
      dim col1(2)
      col1(0)=0
      for i=1 to 2
      col1(i)=TRIM(Request("col1(i)"))
      col1(i)=cINT(col1(i))
      total1=col1(i)+col1(i-1)
      next
      %>
      -------------------------------------------------------
      considering change to following code
      1)
      dim col1(2) means you have 3 elements
      col1(0), col1(1), col1(2)

      2)
      before doing CINT, you have to check the
      parameter, make sure it's Numeric, if it;s
      not, say, a non-numeric string or Null, you
      will get the error : Type Mismatch

      3) this is the right way
      total1 = total1 + col1(i)
      -------------------------------------------------------
      <%
      dim col1(2)
      total1 = 0
      for i=1 to 2
      col1(i)=TRIM(Request("col1(" & i & ")"))
      if isnumeric(col1(i)) then
      col1(i)=cINT(col1(i))
      else
      col1(i)=0
      end if
      total1 = total1 + col1(i)
      next
      %>
      • Great! It works. Rootbear, you solved the problem for me. Thanks you very much.Other friends, thank you anyway, and check out how Rootbear solve this problem. -waokool(waokool); 2002-6-17 (#582892@0)
