Jquery Boolean Iterators

...or what's the proper name for some() and every(). Basically, I'm looking for a function or a plugin that would allow me to write something like: okay = $('#myForm input').every(

Solution 1:

A simple, straightforward implementation:

$.fn.some = function(callback) {
    var result = false;
    this.each(function(index, element) {
        // if the callback returns `true` for one element// the result is true and we can stopif(callback.call(this, index, element)) {
            result = true;
            returnfalse;
        }
    });
    return result;
};

$.fn.every = function(callback) {
    var result = true;
    this.each(function(index, element) {
        // if the callback returns `false` for one element// the result is false and we can stopif(!callback.call(this, index, element)) {
            result = false;
            returnfalse;
        }
    });
    return result;
};

With ES5, arrays already provide the methods every and some, so you could achieve the same with built in methods:

okay = $("#myForm input").get().every(function(element) { 
     return $(element).val().length > 0
});

but it won't work in older IE version without HTML5 shim.

Solution 2:

You can do something like this

okay = $("#myForm input").each(function() { 
     return $(this).val().length > 0
})

okay = $("#myForm input").find('class').each(function() { 
     return $(this).val().length > 0
})
