WMLScript » String » String.trim
- Syntax:
- String.trim(string)
- string
- The mandatory string parameter can be any combination of zero or more characters (letters, numbers, decimal points, etc.) and white spaces. If the value is an empty string, an empty string is returned.
Removes all leading and ending white space in a string.
The String.trim function takes the
given string and removes all of the leading and trailing white spaces
(if any). No white space inside the string (between the characters and
elements) is removed. This function returns the modified string.
You can use the String.squeeze function
to remove extra white spaces between the characters and elements.
