如何解决不再运算比较已经被比较运算过的元素
我们必须对已经比较运算过的元素进行标记,比如a3数组中(a3="sp2=20;sp1=34;sp3=2;sp2=3;sp1=4;")取出sp2=20后会比较运算到后一个sp2=3,此时比较运算后将sp2=3的数组元素编号进行标记,下次循环比较时该元素不计在内。
s_array = split(a3,";")
for i = 0 to ubound(s_array)
for j=i+1 to ubound(s_array)
if getSPName(s_array(i)) = getSPName(s_array(j)) then
Nums = Nums + Cint(getSPNum(s_array(j)))
end if
redim Preserve ID(q)
ID(q) = j
q = q + 1
next
redim Preserve result(p)
result(p) = getSPName(s_array(i)) & "=" & Nums
p=p+1
next
其中定义ID(q)=j就是将当前比较相同的该元素标记,并赋值于动态数组id(q),q默认定义为0,再次循环q=q+1
那么有力该标记,我们就可以有选择性的选择比较累加了。
定义函数
function IsInID(j)
dim x
IsInID = false
for each x in ID
if x = j then
IsInID = true
exit function
End if
Next
end function
主要函数为
function mainhb(s)
s_array = split(s,";")
for i = 0 to ubound(s_array)
if not IsInID(i) then
Nums = getSPNum(s_array(i))
for j=i+1 to ubound(s_array)
if getSPName(s_array(i)) = getSPName(s_array(j)) then
Nums = Nums + Cint(getSPNum(s_array(j)))
redim Preserve ID(q)
ID(q) = j
q = q + 1
end if
next
redim Preserve result(p)
result(p) = getSPName(s_array(i)) & "=" & Nums
p = p + 1
end if
next
for each x in result
mainhb=mainhb&x&";"
next
end function
整体函数为
<%
dim result()
dim ID()
dim p , q , Nums
p=0
q= 0
Nums = 0
redim Preserve ID(q)
ID(q) = ""
s = "sp4=33;sp2=20;sp1=34;sp3=2;sp2=3;sp4=4;"
s = left(s,len(s)-1)
response.write mainhb(s)
function mainhb(s)
s_array = split(s,";")
for i = 0 to ubound(s_array)
if not IsInID(i) then
Nums = getSPNum(s_array(i))
for j=i+1 to ubound(s_array)
if getSPName(s_array(i)) = getSPName(s_array(j)) then
Nums = Nums + Cint(getSPNum(s_array(j)))
redim Preserve ID(q)
ID(q) = j
q = q + 1
end if
next
redim Preserve result(p)
result(p) = getSPName(s_array(i)) & "=" & Nums
p = p + 1
end if
'Nums = 0
next
for each x in result
mainhb=mainhb&x&";"
next
end function
Function getSPName(sp)
getSPName = split(sp,"=")(0)
End Function
Function getSPNum(sp)
getSPNum = split(sp,"=")(1)
end function
function IsInID(j)
dim x
IsInID = false
for each x in ID
if x = j then
IsInID = true
exit function
End if
Next
end function
