function

EVML supports creation of basic function declarations within a single and unbroken <?ev..?> script block.

Syntax

    function name([parameter [..., parameter]]){
        statement;
        [return [expression];]
    }

Where...

Example

<?ev
    function hello(name){
        return 'Hello ' + name;
    }
    print(hello('Bob'));
?>

Function expressions

It is also possible to create a function using an expression. The main difference between a function expression and a function statement is the function's name can be omitted to create anonymous functions.

<?ev
    var person = {
        hello: function(name){
            return 'Hello ' + name;
        }
    };
    print(person.hello('Bob'));
?>

Note EVML is a template language, function support is fairly primitive and restricted to the scope of the template. This means you cannot currently include a file containing a function for use in another template. Functions do not currently support parameters with default values.
