jQuery: analogue of $('p').all() from prototype?

Question

JavaScript

let's say there is a function
function valid(o){ ... ? true : false;}

and you need to check each element for validity
in prototype, this can be done like this
if( $('p').all(valid) ) alert('OK');<br/>

in jQuery, there is only each, which, when return false, stops the further passage through the elements,
but at the exit there is no way to check if the call was interrupted in this way,
you have to do this:

var b=true;<br/>
$('p').each(function(){<br/>
 if(! ....) {b=false; return false;}<br/>
};<br/>
if(b) alert('OK');<br/>

is there a more concise way in jQuery?

Answer 1

if ($('p').is(valid))
Just keep in mind that the function should return true on failure, and not vice versa.

Answer 2

And so you will not be satisfied
if($('p').each(valid($(this).something))) alert ('OK') ;
