jQuery Isotope filter to no items?

Question

I\'m using isotope to filter a list with multiple filters where it is possible that based on a combination of certain filters no items will be displayed. In this case I wan

Answer 1

In addition, to work in Isotope 2 you have to check if it is visible/not visible instead of having the class isotope-hidden:

Like this

var numItems = $('.item:visible').length;

Answer 2

Just to add to what nspace said...

You don't need to add the 'reLayout' callback, you can make the callback in the code you already had here $container.isotope({ filter: filters }); like this:

$container.isotope({ filter: filters }, function noResultsCheck() {
    var numItems = $('.item:not(.isotope-hidden)').length;
        if (numItems == 0) {
        alert("There are no results");
    }
});

This is taken from the docs here: http://isotope.metafizzy.co/docs/introduction.html#script - do a page search for 'callback'.

Just found a great solution at isotopes github issue-page.

Isotope v1:

$container.isotope({ filter: '.my-crazy.awesome.filter' });


if ( !$container.data('isotope').$filteredAtoms.length == 0) {
    // do stuff when no element was found
}

See Isotope Help - accessing the instance

Isotope v2

if ( !$container.data('isotope').filteredItems.length == 0) {
    // do stuff when no element was found
}

You can could to see how many isotope items do not have the "isotope-hidden" class added to it. When the result is 0, it means that all of your elements will be hidden and you can trigger something to happen. You could use a callback function, like reLayout to run every time the isotope gets filtered.

function noResultsCheck() {
    var numItems = $('.item:not(.isotope-hidden)').length;
    if (numItems == 0) {
        //do something here, like turn on a div, or insert a msg with jQuery's .html() function
        alert("There are no results");
    }
}

Add this to your change function:

$container.isotope( 'reLayout', noResultsCheck );
