选中所有复选框

debugcn 发表于 Dev

约翰·比斯利

我正在尝试检查数据表中的所有复选框。我以前已经将此工作了，但我不确定为什么会失败。

这是数据表头。第一个包括复选框输入：

<table id="example1" class="table table-bordered table-hover table-condensed">
  <thead>
    <tr>
      <th><input name="select_all" value="1" id="select_all" type="checkbox" /></th>
      <th>another header</th>
      <th>and another</th>
      <th>few more headers</th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</table>

我真的不想发布任何生成数据表的代码，但以防万一：

function displayRecords()
{
  $.ajax({
    url: 'process/getNVR.php',
    type: 'POST',
    data: '',
    success: function(data, textStatus, jqXHR) {
      var jsonObject = JSON.parse(data); 
      var table = $('#example1').DataTable({
        "dom": "Rlfrtip",
        "data": jsonObject,
        "columns": [
          {
            "data": "",
            "fnCreatedCell": function (nTd, sData, oData, iRow, iCol)
            {
              $(nTd).html("<input type='checkbox' class='checkEdit' id='checkEdit' data-checkbooking='"+oData.booking+"' />");
            }
          },
          { "data": "ANOTHER_HEADER" },
          { "data": "AND_ANOTHER" },
          { "data": "FEW_MORE_HEADERS" }
        ],
        "iDisplayLength": 50,
        "order": [[ 1, "desc" ]],
        "paging": true,
        "scrollY": 550,
        "scrollX": true,
        "bDestroy": true,
        "stateSave": true,
        "scrollCollapse": true,
        "fixedColumns": {
          leftColumns: 2
        },
        "deferRender": true
      });
    },
    error: function(jqHHR, textStatus, errorThrown) {
      console.log('fail: '+ errorThrown);
      return false;
    }
  });
}

我真的不需要为数据表发布代码。也许是我添加的某些东西导致了我的问题。您会注意到，数据表的第一列将包含每个记录的复选框。

这是应该检测何时选中标题复选框的jQuery：

$('#select_all').on('click', function()
{
  var table = $('#example1').DataTable();
  $(':checkbox', table.rows().nodes()).prop('checked', this.checked);   
  console.log('test');
});

如前所述，我之前已经成功使用了此代码。我将其与使用它的先前项目进行了比较。我没看到什么不同。

单击复选框时，我什至无法使控制台显示“测试”。

我想念什么？

编辑

这是一个工作的小提琴。当我说“有效”时，它的工作方式与预期的一样。这使我相信CSS库有问题或其他问题。

编辑2

我想我找到了罪魁祸首。

在页面底部，我正在调用以下JavaScript库：

<script src="https://cdn.datatables.net/fixedcolumns/3.3.0/js/dataTables.fixedColumns.min.js" type="text/javascript"></script>

当我注释掉该库时，一切正常。问题是，我需要固定的列。

DCR

这是您的代码的有效片段。它确实可以工作，但是会产生来自dataTables.css文件的错误。不知道是什么原因导致此错误。我重写了第一个CSS规则，但错误仍然出现。我也将其完全删除，但该错误在下一个块中发生。最后，我直接在摘要的CSS开头添加了dataTable.css内容。这工作了！不知道问题出在stackoveflow还是jquery。在您的机器/服务器上尝试一下，看看会发生什么以确定是否应该将其报告给jquery以获得解决。

注意：建议添加$（'。checkEdit'）。prop（'checked'，this.checked）; 不能解决问题

$(document).ready( function () {
    $('#example1').DataTable();
} );

$('#select_all').on('click', function()
{
	var table = $('#example1').DataTable();
    $(':checkbox', table.rows().nodes()).prop('checked', this.checked);	
    console.log('this is table ' + table);
});
