Selector doesn't work

I've got a problem with my form validation: I have two DIV-container each with two answers. I would like to validate wheter there is minimum checked one radio or there is a value in one text element.

But my jQuery selector doesn't work:

HTML:

<div class="mandatory">
    <input type="radio" value="1" name="answer1" /> Option 1
    <input type="radio" value="2" name="answer1" /> Option 2
</div>

<div class="mandatory">
    <input type="radio" value="1" name="answer2" /> Option 1
    <input type="text" name="answer2" />
</div>

JS:

$('.mandatory').each(function(){
    var elem = $(this).find('input:checked, input:text[value!=""]');
    console.log(elem.attr('name')); //Always "answer2"
});

It returned the input element although it is empty. Here is my code: http://fiddle.jshell.net/Pisi2012/n9S2Y/

Thanks for your help!

You could try Glyn Jones' solution from this other thread:

How can I select a hidden field by value?

So it might look something like this:

var elem = $(this).find('input:checked, input:text').filter(function () { $(this).val() != '' });

What I assume is you need the list of mandatory divs, which does not satisfy the given condition, then try

var els = $('.mandatory').filter(function(){
    var $this = $(this);

    return !$this.find(':radio:checked').length && !$this.find(':text').filter(function(){return $.trim(this.value) != ""}).length
});

Demo: Fiddle

Your input doesn't have a value attribute, so the attributes selector matches, as the value isn't an empy string, there just is no value ?

Change

<input type="text" name="answer2" />

to

<input type="text" name="answer2" value="" />

Try this code :

$('.mandatory').each(function(){
    var elem = $(this).find('input:checked, input[type="text"][value!=""]');
    console.log(elem.attr('name')); //Always "answer2"
});
