17.3. Removing All Leading and Trailing Whitespaces of a String: trim() Function
The trim() function helps us remove all leading and trailing whitespaces of a string. Its syntax is:
String.trim(string);
The trim() function returns invalid if any error occurs.
The following WMLScript examples demonstrate the use of trim():
x
= String.trim(" WAP Tutorials ");
y =
String.trim("WAP Tutorials");
After executing the above script, both x and y contain the string value "WAP Tutorials".
