WMLScript » String » String.toString
- Syntax:
- String.toString(value)
- value
- The mandatory value 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.
Converts a given value to a string.
The
String.toString function takes the given value and converts it
into a string. The value can be a boolean, fixed-point number,
floating-point number, or even a string. The converted value is
returned. If the value is invalid, then this function returns
invalid.
Once the value is converted,
you can use the String.trim function to remove all leading and
trailing white space. You can also use the String.squeeze to
remove extra white spaces between characters and elements.
