JavaScript/jQuery equivalent of LINQ Any()
Solution 1:
These days you could actually use Array.prototype.some
(specced in ES5) to get the same effect:
array.some(function(item) {
return notValid(item);
});
Solution 2:
You could use variant of jQuery is
function which accepts a predicate:
$(array).is(function(index) {
return notValid(this);
});
