Rails spinoffs - May 2007 - SV: Returning (not only breaking) from a Hash.each()

Try something like:


function f() {
  ...
  if (myHash.find(function(item) { return !o.isOk; })) {
    return;
  }
  ... //not always executed
}

Emne: [Rails-spinoffs] Returning (not only breaking) from a Hash.each()
 

Hi,

How can I achieve the equivalent of the following code with a
Hash.each() iterator ? :

function f() {
	...
	for (var i in o) {
		if (!o.isOk) {
			return;
		}
	}
	... //not always executed
}

My problem is how to implement the RETURN statement.


For if I write this :

function f() {
	...
	myHash.each (
		function(item) {
			if (!o.isOk) {
				return;
			}
		}
	);
	... //always executed !!!
}

here the return statement is equivalent of a simple break of the loop,
whereas I really want to quit the top function !

Any idea ?

Christophe
