How would I adapt this code to show a <div>No Results Found</div> on the page when no results are found?
I've got this simple image gallery with an input to filter results based on the contents of the data-filter attribute:
<input type="text" name="filter" placeholder="Filter" id="filter">
<div class="results-gallery">
<div class="gallery-thumbnail" data-filter="Apple">image</div>
<div class="gallery-thumbnail" data-filter="Orange">image</div>
<div class="gallery-thumbnail" data-filter="Banana">image</div>
</div>
And the jQuery:
$("#filter").keyup(function() {
var value = $(this).val().toLowerCase();
$(".gallery-thumbnail").filter(function() {
$(this).toggle($(this).attr("data-filter").toLowerCase().indexOf(value) > -1);
});
});

You could use the same method and do it like this:
$(document).ready( function(){
$("#filter").keyup( function(){
var value = $(this).val().toLowerCase();
$(".gallery-thumbnail").filter(function() {
$(this).toggle($(this).attr("data-filter").toLowerCase().indexOf(value) > -1);
});
$('.noresult').toggle($(".gallery-thumbnail:visible").length == 0)
});
});

You put 'No Results' div on the page, with a class which initially defaults it to be hidden (display:none). If your filter returns no results, you add a class to the div to show it (display: block). When the filter is cleared, and you have results again, you remove the 'show' class, reverting it back to it's default 'hidden' state.
