选择哪些复选框处于非活动状态

  • 772

请告诉我如何检查。如果我选择了一个或多个 filter=one 复选框，而其他所有复选框均未选中，则显示一条消息。

$('button').on('click', function() {
 if ( $('input[filter=one]:checked') && $('input:not([filter=one]):not(:checked)')) {
 alert(1);
 }
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input filter="one" type="checkbox" checked>
<input filter="one" type="checkbox" checked>
<input filter="one" type="checkbox" checked>
<input filter="one" type="checkbox" checked>

<br/>

<input filter="two" type="checkbox">
<input filter="two" type="checkbox" checked>
<input filter="two" type="checkbox">
<input filter="two" type="checkbox">

<br/>

<input filter="three" type="checkbox">
<input filter="three" type="checkbox">
<input filter="three" type="checkbox">
<input filter="three" type="checkbox">

    如果在第一组中至少有一个选中的复选框并且在其余组中选中了零，则必须为真。

    $('button').on('click', function() {
  let check1 = $('input[filter=one]:checked');
  let check2 = $('input:not([filter=one]):checked');

  if (check1.length > 0 && check2.length == 0) alert(1);
});
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input filter="one" type="checkbox" checked>
<input filter="one" type="checkbox" checked>
<input filter="one" type="checkbox" checked>
<input filter="one" type="checkbox" checked>

<input filter="two" type="checkbox">
<input filter="two" type="checkbox" checked>
<input filter="two" type="checkbox">
<input filter="two" type="checkbox">

<input filter="three" type="checkbox">
<input filter="three" type="checkbox">
<input filter="three" type="checkbox">
<input filter="three" type="checkbox">
