Check if all elements satisfy a condition

I need a jQuery filter/map/each type function to check if ALL elements satisfy a condition:

function areAllValid(inputs){
     return $.someFunction(inputs, function(input) { return input.length > 0; }); 
}

If ALL inputs have length > 0 someFunction should return true. Anything like this in jQuery?

There are some minor optimization issues unaddressed by the existing answers, so I'll throw my hat in the ring with what I believe is the most readable/performant code.

Add a jQuery extension method like this which will short circuit :

<!-- language: lang-js -->

/** 
* Determines whether all elements of a sequence satisfy a condition.
* @@param  {function} predicate - A function to test each element for a condition.
* @@return {boolean}  true if every element of the source sequence passes the test in the specified predicate
*/
$.fn.all = function (predicate) {
    $(this).each(function (i, el) {
        if (!predicate.call(this, i, el)) return false;
    });
    // we made it this far, we're good.
    return true;
};

Then call it like this:

<!-- language: lang-js -->

var allValid = $("form :input").all(function () {
                   return $(this).valid();
                });
