WMLScript » Statements » return
- Syntax:
- return
The
return statement is used inside a function to set the value of
the function. This is the value returned by the call of the function. A
function can only return one value. If no value is assigned during the
function call, then the function has a default value of an empty string
"". Therefore, a called function always returns a value, even if it is
just an empty string.
Note that once the
return is executed, you immediately leave the function and
return to where the function call was made from within the code. The
function will now have the value that was returned and you can assign
that value to a named variable (use the var statement to
initialize the variable).
