在我的网站上，我添加了 3 个过滤器、燃料类型、驱动类型和车辆类型，我得到了半工作代码，它根据选择框显示汽车，但是有一个问题，我希望它不显示其他选择. 例如，当您选择汽油车时，它会显示一些不是手动的汽车，而是汽油车，我只希望它显示完全匹配，所以如果您选择汽油手动车，它只会显示汽油和手动的汽车和汽车。

 $(function () {
            var fuel = ''; // Keep track of selections
            var drive = '';
            var type = '';
            $('#fuel select').on("change", function () {
                fuel = ($(this).val() === 'all' ? '' : '[class*="' + $(this).val() + '"]');

这就是你应该如何编写脚本的方式，我在 JSFiddle 上检查了它，它可以工作。JSFiddle 示例可以在这里找到：点击这里

$('#fuel select').on("change", function() {
    selectModels();
});
$('#drive select').on("change", function() {
    selectModels();
});
$('#type select').on("change", function() {
    selectModels();
});

function selectModels() { // Select matching models
    var fuel = $("#fuel select :selected").val();
    var drive = $("#drive select :selected").val();
    var type = $("#type select :selected").val();
    //alert("[" + fuel + "/" + drive + "/" + type + "]");

    var extraClasses = '';    
    if(fuel && fuel != "all") {
        extraClasses += "." + fuel;
    }
    if(drive && drive != "all") {
        extraClasses += "." + drive;
    }
    if(type && type != "all") {
        extraClasses += "." + type;
    }
    //alert(extraClasses);

    $('div.modelContainer').hide(); // Hide all
    $('div.modelContainer' + extraClasses).show(); // Show matches
}​
