This tutorial
will teach you all of the basic string functions available
in ASP using VBScript. I will keep things concise as
possible. The following is a list of the functions
and an example of each.
Asc();
Asc() will provide you with the ASCII character code
of the character in the parentheses.
<%
str1 = Asc("B")
response.write str1
%> |
cStr();
cSrt() will convert a numeric value into a string.
<%
int1 = 35
str1 = cStr(int1)
%> |
inStr();
inStr() will locate the occurance of a character (or
set of characters) in a string and output it's place.
<%
str1 = "ABCDEF"
str2 = inStr(str1,"BC")
response.write str2
%> |
LCase();
LCase() will convert an entire string to lowercase.
<%
str1 = "ABCDEF"
str2 = LCase(str1)
response.write str2
%> |
UCase();
UCase() will convert an entire string to uppercase.
<%
str1 = "abcdef"
str2 = UCase(str1)
response.write str2
%> |
Trim();
Trim will remove all blank spaces from the beginning
or end of a string.
<%
str1 = " ABCDEF"
str2 = Trim(str1)
response.write str2
%> |
Len();
Len() will tell you the number of characters in a string.
<%
str1 = "ABCDEF"
str2 = Len(str1)
response.write str2
%> |
Replace();
Replace() will replace a character (or set of characters)
with another character (or set of characters).
<%
str1 = "ABCDEF"
str2 = Replace(str1,"CD","YZ")
response.write str2
%> |
Split();
Split() will split a string into an array of values
based on the character defined.
<%
str1 = "ABC,DEF"
str2 = Split(str1,",")
response.write str2(0)
response.write ""
response.write str2(1)
%> |
Left();
Left() will retrieve the number of characters specified
from the left of the string.
<%
str1 = "ABCDEF"
str2 = Left(str1,3)
response.write str2
%> |
Right();
Right() will retrieve the number of characters specified
from the right of the string.
<%
str1 = "ABCDEF"
str2 = Right(str1,3)
response.write str2
%> |
Mid();
Mid() will retrieve the number of characters specified
from the middle of the string.
<%
str1 = "ABCDEF"
str2 = Mid(str1,3,2)
response.write str2
%> |
That's it! Have fun playing with
strings.
