Try this code: http://jsfiddle.net/ZsPyy/4/

I have passed the button to the required_valid function. So we can get the btn's parent form.

function required_valid(btn) {
    var result = true;
    $(btn).closest("form").find('.required').each(function () {
        if (!$(this).val()) {
            //var cssObj=;
            $(this).css("background", "#ffc4c4");
            result = false;
        }
        $(this).keyup(function () {
            $(this).css("background", "#FFFFEC");
        })
    });
    return result;
}
$('button').live('click', function(e) {
    e.preventDefault();
    var passed = true;
    //passed = required_selectbox() && passed;
    passed = required_valid(this) && passed;
    if (!passed) {
        return false;
    }
});

function required_valid(sbtn) {
    var result = true;
    $(sbtn).closest("form").children('.required').each(function () {
        if (!$(this).val()) {
            //var cssObj=;
            $(this).css("background", "#ffc4c4");
            result = false;
        }
        $(this).keyup(function () {
            $(this).css("background", "#FFFFEC");
        })
    });
    return result;
}
$('button').live('click', function(e) {
    e.preventDefault();
    var passed = true;
    //passed = required_selectbox() && passed;
    passed = required_valid(this) && passed;
    if (!passed) {
        return false;
    }
});
