我正在尝试使以下代码工作,但是我的 jQuery 技能太基础了,我找不到问题

此代码旨在根据复选框数组过滤列表

该代码很可能没有错误

问题肯定来自一些愚蠢的事情,比如没有正确声明、没有在正确的条件下进行测试或没有调用所需的脚本

太感谢了!

        if($(this).is(':checked')) {
            $("#events li."+$(this).attr('id')).removeClass('type_hidden');
            if(!$("#events li."+$(this).attr('id')).hasClass('start_hidden')) {
                $("#events li).not(".type_hidden, .start_hidden").slideDown();

你需要一些东西来过滤结果取决于复选框
检查它

HTML

<div class="tags">
  <label><input id="ss" type="checkbox" rel="arts" /> Arts </label><label>
  <input id="aa" type="checkbox" rel="computers" /> Computers </label><label>
  <input type="checkbox" rel="health" /> Health </label><label>
  <input type="checkbox" rel="video-games" /> Video Games </label>
</div>
<p></p>
<p></p>
<hr />
<div id="sso">
  Click to uncheck #Computers</div>
<p></p>
<p></p>
<hr />
<ul class="results">
  <li class="arts computers">Result 1 </li>
  <li class="video-games">Result 2 </li>
  <li class="computers health video-games">Result 3 </li>
  <li class="arts video-games">Result 4 </li>
</ul>

jQuery

    $(document).ready(function () {

    $(':checkbox').click(function () {
        if ($(':checkbox:checked').length > 3) {
            alert('you can not check more than 3 checkboxes');
            $(this).prop('checked', false);
        }
    });
}) $('div.tags').delegate('input[type=checkbox]', 'change', function () {
    var $lis = $('.results > li'),
    $checked = $('input:checked');

    if ($checked.length) {
        var selector = $checked.map(function () {
                return '.' + $(this).attr('rel');
            }).get().join('');
        var $results = $lis.hide().filter(selector);

        if ($results.length > 0) {
            $('.no-results-found').remove();
            $results.show();
        } else {
            $('.results').append('<li class="no-results-found">No results found.</li>');
        }
    } else {
        $lis.show();
    }

    //click to uncheck

    $('#sso').on('click', function (ev) {
        $("#aa").prop("checked", false);
        var $results = $lis.show().filter(selector);
    });

});

在您的代码中,您有这一行

  $("#events li).not(".t.........

更改:

   $("#events li").not(".t
