' Cxstr2:cxstr1 the split symbol.

Here is the test code:

Copy Code code as follows:

<%s1 = "Abc,aa,bb,cdef,bc,abcdef,hhgg,gggg,cde,edc"
S2 = "1,2,3,11,22,33,12,13,14,11,33,333,14"
S3 = ""
S4 = "SDF,ABC,12,2,2,ABC"
S5 = Split (S4)
Response.Write "String for character characters:" &array_no (S1, ",", 0) & "<br>"
Response.Write "String is a number:" &array_no (S2, ",", 0) & "<br>"
Response.Write "String is empty:" &array_no (S3, ",", 0) & "<br>"
Response.Write "String is mixed:" &array_no (S4, ",", 0) & "<br>"
Response.Write "String is an array:" &array_no (S5, ",", 0) & "<br>"
Response.Write "String is an unknown variable:" &array_no (S33, ",", 0) & "<br>"
Response.Write "Extract a certain when not exceeding the subscript:" &array_no (S1, ",", 2) & "<br>"
Response.Write "Extracts a certain time, when exceeding subscript:" &array_no (S1, ",",) & "<br>"%>

Test results:

Copy Code code as follows:

string as word characters: Abc,aa,bb,cdef,bc,abcdef,hhgg,gggg,cde,edc
When a string is a number: 1,2,3,11,22,33,12,13,14,333
When string is empty: no data
When a string is mixed: sdf,abc,12,2
When a string is an array: Sorry, parameter 1 cannot be an array
String is an unknown variable: no data
When one is extracted, no more than the subscript: BB
When one is fetched, when the subscript is exceeded: EDC

The main is to increase the judgment

Copy Code code as follows:

Do While InStr (Cxstr1, ",,") >0
Cxstr1=replace (Cxstr1, ",,", ",")
Loop
If Right (cxstr1,1) = "," Then
Cxstr1=left (Cxstr1,len (CXSTR1)-1)
