Implementing Isotope filters (basic)

Question

I'm trying to implement Isotope's filtering on a news section of a WordPress installation. I'm new to JavaScript / jQuery and am trying to learn on the go. I started by using the code provided in the Filters section of the Isotope website.

Having had no luck, I started Googling. On Stack Overflow I found Implementing isotop filtering portfolio with wordpress which looked promising but had no responses. Then I found Implementing jQuery isotope. I thought, wow, alright same exact question. Answered. Great.

...but my excitement soon turned to even more frustration. I am still sitting here after hours of tinkering without having anything to show for it.

My simple question is, what am I doing wrong / missing / not understanding?

Thanks in advance for your help, forgetfuljames

Answer 1

You are simply missing an opening brace (and the .'s on your selectors as you found):

<script type="text/javascript">

$(window).load(function() { <<<<

    // cache container
    var $container = $('#isotope_container');

    // initialize isotope
    $container.isotope({
    // options...
    animationEngine: 'best-available',
    itemSelector: '.isotope_selector'
    });

    // filter items when filter link is clicked
    $('#isotope_filters li a').on('click', function() {
    var selector = $(this).data('filter');
    $container.isotope({
    filter: selector
    });

});
</script>

For future visitors of this question I leave the code working (without Css)

Code Snippet

$(window).load(function()
{
    // cache container
    var $container = $('#isotope_container');

    // initialize isotope
    $container.isotope({
    // options...
    animationEngine: 'best-available',
    itemSelector: '.isotope_selector'
    });

    // filter items when filter link is clicked
    $('#isotope_filters li a').on('click', function() {
    var selector = $(this).data('filter');
    $container.isotope({
    filter: selector
    });

}); });
