Question

Short

What I want to do is following: At first, function validate() must check all inputs one by one: if they are not empty (or whitespaced) then move to if statement (for checking radio buttons) But if some of inputs empty then stop whole validate function and focus on empty input.

Here is result: http://jsfiddle.net/tt13/y53tv/4/

Just press ok button, you’ll see that it finished first function and fires if too. But I want to exit from whole validate() function in case there is empty field, not only from each() function

Detailed

JS

function validate() {
    $('.var_txt').each(function() {
        if ($.trim($(this).val()) == '') {
            $(this).focus();
            return false;
        }
    });

    if (!$(".answer:checked").val()) {
        alert("boom");
        return false;
    }
    return true;
}
$(document).ready(function() {
    $("#add_question").submit(function(e) {
        if (validate()) {
            alert("good");
        }
        e.preventDefault();
    })
});​

Answer 1

Add a flag that has to be false to continue.

function validate() {
    var invalid = false;
    $('.var_txt').each(function() {
        if ($.trim($(this).val()) == '') {
            $(this).focus();
            invalid = true;
            return false;
        }
    });
    if (invalid) {
        return false;
    }

    if (!$(".answer:checked").val()) {
        alert("boom");
        return false;
    }
    return true;
}
$(document).ready(function() {
    $("#add_question").submit(function(e) {
        if (validate()) {
            alert("good");
        }
        e.preventDefault();
    })

});​
