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...
name
The function name. |
parameter
The name of an argument to be passed to the function. |
statement
The statements to be executed when the function is called. |
return
Optionally you can return from the function causing the function to terminate. |
expression
The expression to return. |
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.
