jQuery: Select data attributes that aren't empty?

I'm trying to select all elements that have a data-go-to attribute that is not empty.

I've tried $('[data-go-to!=""]') but oddly enough it seems to be selecting every single element on the page if I do that.

Just as further reference, and an up-to-date (may'14) (aug'15) (sep'16) (apr'17) (mar'18) (mar'19) (may'20) (jan'22)...
Answer that works with:

###Empty strings: If the attr must exist & could have any value (or none at all)

    jQuery("[href]");

###Missing attributes: If attr could exist & if exist, must have some value

    jQuery("[href!='']");

###Or both: If attr must exist & has to have some value...

    jQuery("[href!=''][href]");

PS: more combinations are possible...

###Check this test in jsFiddle for examples:

###Or here in SO with this Code Snippet.
* Snippet is running jQuery v2.1.1

jQuery('div.test_1 > a[href]').addClass('match');
jQuery('div.test_2 > a[href!=""]').addClass('match');
jQuery('div.test_3 > a[href!=""][href]').addClass('match');
div,a {
    display: block;
    color: #333;
    margin: 5px;
    padding: 5px;
    border: 1px solid #333;
}
h4 {
    margin: 0;
}
a {
    width: 200px;
    background: #ccc;
    border-radius: 2px;
    text-decoration: none;
}
a.match {
    background-color: #16BB2A;
    position: relative;
}
a.match:after {
    content: 'Match!';
    position: absolute;
    left: 105%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="test_1">
    <h4>Test 1: jQuery('a[href]')</h4>
    <a href="test">href: test</a>
    <a href="#">href: #</a>
    <a href="">href: empty</a>
    <a>href: not present</a>
</div>
<div class="test_2">
    <h4>Test 2: jQuery('a[href!=""]')</h4>
    <a href="test">href: test</a>
    <a href="#">href: #</a>
    <a href="">href: empty</a>
    <a>href: not present</a>
</div>
<div class="test_3">
    <h4>Test 3: jQuery('a[href!=""][href]')</h4>
    <a href="test">href: test</a>
    <a href="#">href: #</a>
    <a href="">href: empty</a>
    <a>href: not present</a>
</div>

try

$(':not([data-go-to=""])')

UPDATE:

For the sake of not leading anyone astray, this answer will work in older versions of jQuery but is not future-proof. Since @gmo and @siva's answers both seem to be working with later versions I defer to (and encourage you to upvote) their answers....and of course hope you have a fantastic day.

Has 'data-attributename' and its value is not empty: 

$('[data-attributename]:not([data-attributename=""])')

Has 'data-attributename' empty or not:

$('[data-attributename]')

$('[data-go-to]').filter(function() {
    return $(this).data('go-to')!="";
});

Using :not, .not(), :empty etc will only check if the element itself is empty, not the data attribute. For that you will have to filter based on the data attributes value.

According to the documentation this should do it

:not([attr="value"])

DEMO

Hope this helps

I'm not sure about a simple selector, but you could use filter():

$('[data-go-to]').filter(
    function(){
        return ($(this).attr('data-go-to').length > 0);
    });

JS Fiddle demo.
