我正在尝试让 Metafizzy 的 Isotope 插件正常工作。这是我的设置，除了我从 sql 数据库中提取容器项目 - http://jsfiddle.net/trewknowledge/jJZEN/

谁能帮我弄清楚为什么它不起作用？

这是我正在使用的代码

JavaScript

    //Load all items straight away
    $(document).ready(function(){  
        showEntries('*');
    });  

    //Isotope filter
    function filterEntries() {
        var $container = $('#entries');
           $select = $('#filters select');

        $container.isotope({
            itemSelector: '.item'
        });

        $select.change(function() {
            var filters = $(this).val();
            $('.active').removeClass('active');
            if (filters != '.item') {
                $( filters).addClass('active');
            }
            $container.isotope({
                filter: filters
            });
        });

    };


    //Pull in data from database
    function showEntries(str) {

        if (str=="") {
            document.getElementById("entries").innerHTML="";
            return;
        }
        if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp=new XMLHttpRequest(); 
        }
        else {// code for IE6, IE5
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
            xmlhttp.onreadystatechange=function() {
                if (xmlhttp.readyState==4 && xmlhttp.status==200) {

                    document.getElementById("entries").innerHTML=xmlhttp.responseText;

                }
        }
            xmlhttp.open("POST","<?php bloginfo('template_url'); ?>/getentries.php?q="+str,true);
            xmlhttp.send();

            //Fire filter function
            filterEntries();
        }
</script>

    $q=$_GET["q"];

    //Remove the '.item' before the cat id
    $q= ltrim ($q,'.item');

    $con = mysql_connect("localhost", "root", "root");
    if (!$con) {
        die('Could not connect: ' . mysql_error());
    }

    mysql_select_db("awards", $con);

    if ($q === "all" || $q === "*" ) {
        //Show all entries that have status registered if all is selected
        $sql="SELECT * FROM entry WHERE  status = 'registered'";
    } else {    
        //Else just show category entries of people who are registered
        $sql="SELECT * FROM entry WHERE awards_subcategory_id = '".$q."' && status = 'registered'";
    }
    $result = mysql_query($sql);


    while($row = mysql_fetch_array($result)) {

        print "<div class='item item$q'>";
        print '<img class="image" src="http://localhost:8888/awardsite/wp-content/themes/award/placeholder.jpg" />';
        print "<p class='studio'> Studio: " . $row['studio'] . "</p>";
