标签: jquery checkbox checked

$(document).ready(function() {
  $('#table tr').click(function() {
    if ($('input[type=checkbox]', this).is(':checked')) {
      $(this).removeClass('bg-success');
      $('input[type=checkbox]', this).prop('checked', false);
    } else {
      $(this).addClass('bg-success');
      $('input[type=checkbox]', this).prop('checked', true);
    }
  });
});
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="table" class="table">
  <tr class="bg-success">
    <th><input type="checkbox" name="param[1]" value="1" checked></th>
    <td><strong>abc</strong></td>
    <td>abc</td>
    <td>abco</td>
  </tr>
  <tr>
    <th><input type="checkbox" name="param[2]" value="1"></th>
    <td><strong>def</strong></td>
    <td>def</td>
    <td>def</td>
  </tr>
  <tr>
    <th><input type="checkbox" name="param[3]" value="1"></th>
    <td><strong>ghi</strong></td>
    <td>ghi</td>
    <td>ghi</td>
  </tr>

我有一张表格,每行都有复选框。单击表格行后,复选框处于选中状态或未选中状态。那没问题。但是,如果我恰好在复选框内单击,它将无法正常工作。谢谢您的帮助。

这是我在FIDDLE中的代码。 https://jsfiddle.net/o9w6v4pu/

$(document).ready(function() {
  $('#table tr').on('click', function(e) {
    var $tr = $(this);
    var $checkbox = $('input:checkbox', this);
    
    if (!$checkbox.is(e.target)) {
      // the user did not click the checkbox, so flip its state
      $checkbox.prop('checked', !$checkbox.prop('checked'));
    }
    
    //toggle the bg-success class
    $tr.toggleClass('bg-success', $checkbox.prop('checked'));
  });

我认为您不必担心更改检查状态。

$(document).ready(function() {
  $('#table tr').click(function() {
    if ($('input[type=checkbox]', this).is(':checked')) {
      $(this).addClass('bg-success');
    } else {
      $(this).removeClass('bg-success');
    }
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="table" class="table">
  <tr class="bg-success">
    <th><input type="checkbox" name="param[1]" value="1" checked></th>
    <td><strong>abc</strong></td>
    <td>abc</td>
    <td>abco</td>
  </tr>
  <tr>
    <th><input type="checkbox" name="param[2]" value="1"></th>
    <td><strong>def</strong></td>
    <td>def</td>
    <td>def</td>
  </tr>
  <tr>
    <th><input type="checkbox" name="param[3]" value="1"></th>
    <td><strong>ghi</strong></td>
    <td>ghi</td>
    <td>ghi</td>
  </tr>
