DataTables列过滤奇怪的行为

时间:2015-06-12 03:00:41

标签: datatables

我在http://live.datatables.net/fizajopa/1

中发布了一个测试用例

步骤:

  1. 过滤导致表数据计数更改的任何列。

  2. 点击该行。 - >弹出窗口未显示。 [WRONG]

  3. 再次点击该行。 - >弹出窗口显示。

  4. 使用列过滤器后,我需要取消焦点列过滤器,然后我可以触发行点击事件。

    问题:这是一个错误吗?怎么解决?

这不是一个错误,它是预期的行为。您正在使用分页表,然后

$('#example td').click( function () {
   alert('x');
});

已执行,您实际上只将点击处理程序附加到第{1}页上的<td> <td>,即<td>页面。您必须使用委派的事件处理程序,以便随时定位所有$('#example').on('click', 'td', function () { alert('x'); }); ,以及动态注入DOM的那些:

blur()

您的演示已编辑 - &gt;的 http://live.datatables.net/fizajopa/3/edit

更新,我看到了问题。只需在过滤器输入处理程序中调用$("#example thead th input[type=text]").on( 'keyup change', function () { table .column( $(this).parent().index()+':visible' ) .search( this.value ) .draw(); $(this).blur() //<---- });

<input>

但是,如果用户想要输入更多内容,那么每次输入或更改任何内容时,这将从var delay = (function(){ var timer = 0; return function(callback, ms){ clearTimeout (timer); timer = setTimeout(callback, ms); }; })(); // Apply the filter $("#example thead th input[type=text]").on( 'keyup change', function () { var that = this; delay(function(){ table .column( $(that).parent().index()+':visible' ) .search( that.value ) .draw(); $(that).blur() }, 500); }); $('body').on('click', 'td', function () { alert('x'); }); 中移除焦点。为避免这种情况,您可以使用类似jQuery .keyup() delay的方法:

$('#example tbody').on('click', 'td', function(){
   alert('x');
});

不知道500ms是否合适,你可以尝试一下。

答案 1 :(得分:2)

您需要使用委托事件处理程序,因为在重绘表时会重新创建单元格,例如在过滤或更改页面之后。

以下是您需要更新以正确处理点击次数的代码:

$(document).ready( function () {
  var table = $('#example').DataTable();
  
  // Apply the filter
  $("#example thead th input[type=text]").on( 'keyup change', function () {
    table
	  .column( $(this).parent().index()+':visible' )
	  .search( this.value )
	  .draw();
  } );
  
  $('#example tbody').on('click', 'td', function (){
     alert('x');
  });
} );

答案 2 :(得分:1)

上述解决方案对我不起作用,因为我希望用户能够继续输入文本,无论他们放置鼠标光标的位置或者他们在按键之间等待多长时间。相反,我决定只在他们按下输入时更新表格并在此功能结束时调用模糊。最好的部分是这只需要一行代码。我的实现在

之下
//set listeners for text filters
$("#productTpjTable thead input").on('keyup change', function (e) {
    if(e.which == 13) {
        table
            .column($(this).parent().index() + ':visible')
            .search(this.value)
            .draw();
    }
});

答案 3 :(得分:1)

就我而言,就像davidkonrad建议的那样,我在过滤器输入处理程序中应用模糊处理,但是紧接着我将注意力集中在模糊处理上。因此,用户可以继续输入过滤器,并且行单击将按预期工作。试试吧!

示例:

$("#example thead th input[type=text]").on( 'keyup change', function () {

   //...filtering
   $(this).blur();
   $(this).focus();

});

答案 4 :(得分:0)

我使用了带有blur()的鼠标离开功能,这提供了一个简单的解决方案。

$('.exampledatatables thead tr th').each(function (i) {
    var title = "Search" + $(this).text();
    table.columns().eq(0).each(function (colIdx) {
        $('input', table.column(colIdx).header()).on('keyup change', function () {
            table
                .column(colIdx)
                .search(this.value)
                .draw();
        });
        $('input', table.column(colIdx).header()).mouseleave(function () {
            $(this).blur()
        }); 
    });
});

这对我来说现在很好。请告诉我这样使用是否有任何问题。
