I think whatever ECMA says about 'return' is meaningless for
Javascript because everything is essentially a function in web
programming with javascript.
Well, first of all, Javascript is a trade name for the language
specified by the ECMA-262 specification, which is called "ECMAScript"
in the specification itself. So by definition, whatever is in there
applies to JavasScript. Whether or not a given Javascript
implementation chooses to follow the standard is another matter.
For example, something like <p onclick='afunction()'> has to
implicitly return(true) in order for the browser to know that the
click worked. What if afunction doesn't return true or, worse yet,
returns false? Then you'd have to modify the code to <p
onclick='afunction();return true'> which means you have to consider
the entire onclick javascript string as a function with an implicit
wrapper.
They are, in fact, implemented as anonymous functions (a.k.a.
closures). Putting this in your HTML:
