Jquery通过多个复选框过滤表格行

Question

我正在尝试获取表格的过滤器。我想要的是复选框根据它们是否被选中来筛选（隐藏）行，以及该值是否存在于表格单元格中。我有点工作，但它只会对其中一个复选框进行排序。另外，如果表格单元格中有多个值被过滤，则该行将被隐藏。思考？预先感谢您的任何帮助。出于某种原因，我真的很困难！

这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(); 
} 
}); 

的标记如下（请原谅一些混乱，其WordPress的）

<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="Junior">Junior

Answer 1

正如我认为你只是在呼唤第一复选框[0]

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

呼叫所有由相同的

插入成才

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

你的代码工作正常，这里是一个简化版本

$("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(); 
 
    } 
 
});
