Trim, LTrim and RTrim VBScript functions

You can use the Trim function to remove spaces on both the left and the right side of a string.

syntax: Trim(string)

Example 1:

<%
myString=" This is an example using the Trim function. "
Response.write Trim(myString)
%>

Output:

This is an example using the Trim function.

The LTrim function will remove spaces on the Left and the RTrim function will remove spaces on the right.
Imagine you created an online form with a textfield called 'txtName' and the visitor accidentally hit the space bar before filling in his name. The Request.form("txtName") command would retrieve his name with an accidental space before his name, so it can be good practice to use the Trim function for this eventuality as the example below shows.

<%
varName=Trim(Request.Form("txtName"))
%>
