Question

我正在尝试使用过滤器来处理表格。我想要的是根据是否检查行以及表格单元格中是否存在值来过滤（隐藏）行的复选框。我有点工作，但它只会对其中一个复选框进行排序。此外，如果要过滤的表格单元格中有多个值，则该行将被隐藏。思考？预先感谢您的任何帮助。我出于某种原因真的很挣扎！

以下是我一直在使用的代码：

$("input:checkbox").click(function () {
var showAll = true;
$('tr').not('.first').hide();
$('input[type=checkbox]').each(function () {
    if ($(this)[0].checked) {
        showAll = false;
        var status = $(this).attr('rel');
        var value = $(this).val();            
        $('td.' + 'status' + '[rel="' + value + '"]').parent('tr').show();

    }
});
    if(showAll){
    $('tr').show();
}
});

标记如下（请原谅一些混乱，其Wordpress）

<div class="grants-filter">
<h3 class="filter-title">Filter Scholarships</h3><br/>
<h3>Year of Study:</h3>
<input type="checkbox" name="chx" rel="status" value="Freshman">Freshman
<input type="checkbox" name="chx" rel="status" value="Sophmore">Sophmore

Answer 1

我认为你只是在调用第一个复选框[0]

if ($(this)[0].checked) {

通过插入像

这样的内容来调用所有内容

$('input[type=checkbox]').each(function () {
           if (this.checked) {
               console.log($(this).val()); 
           }
});

您的代码运行正常，这是一个简化版本

＆＃13;

$("input:checkbox").click(function() {
  var showAll = true;
  $('tr').not('.first').hide();
  $('input:checkbox:checked').each(function() {
    showAll = false;
    var status = $(this).attr('rel');
    var value = $(this).val();
    $('td.' + 'status' + '[rel="' + value + '"]').parent('tr').show();
  });
  if (showAll) {
    $('tr').show();
  }
});
