jQuery returns undefined

I have a really basic problem

$('#myForm').submit(function() {
    var v= input_value(this,'validate_code');
    alert(v);
}

function input_value(form, name){
    var emptyFields = $(":input").filter(function() {
            if(this.name == name) {
            alert(this.value);
                return this.value;  
                }
    });
}

Why does alert(this.value) show the real value and alert(v) shows 'undefined' ?

The callback function you pass to filter will not make the outer function input_value return. The return statement inside the callback is only used to to decide whether to keep the element or not.

If you really want to get the empty fields, you would have to negate the value:

var emptyFields = $(":input").filter(function() {
    return !this.value;  
});

The question is, what do you want v to be?
