请查看此JSFiddle example,我不知道为什么它不起作用。我呆了几个小时,感觉就像在地板上敲笔记本电脑。
附言我是JavaScript和jQuery的新手。



var $results = $('.result'),
  $checks = $(':checkbox[name^=fl]');

$checks.change(function() {
  var $checked = $checks.filter(':checked');
  /* show all when nothing checked*/
  if (!$checked.length) {
    $results.show();
    return; /* quit here if nothing checked */
  }
  /* create array of checked values */
  var checkedVals = $.map($checked, function(el) {
    return el.value
  });
  /* hide all results, then filter for matches */
  $results.hide().filter(function() {
    /* split categories for this result into an array*/
    var cats = $(this).data('category').split(' ');
    /* filter the checkedVals array to only values that match */
    var checkMatches = $.grep(checkedVals, function(val) {
      return $.inArray(val, cats) > -1;
    });
    /* only return elements with matched array and original array being same length */
    return checkMatches.length === checkedVals.length;
    /* show results that match all the checked checkboxes */
  }).show();
  /* do something when there aren't any matches */
  if (!$results.length) {
    alert('Ooops...no matches');
  }
});

最佳答案

您的选择器错误。

$checks = $(':checkbox[name^=fl]');


应该

$checks = $(':checkbox[name^=f1]');
