## 实现 ##

### html ###

<table id="wmsReceiveOrder_table_id" class="table table-striped table-bordered hover" style="width:100%">
                        <thead>
                        <tr>
                            <th class="badao_Center">序号</th>
                            <th>收货单号</th>
                            <th>收货日期</th>
                            <th>收货人</th>
                            <th>供应商编号</th>
                            <th>供应商名称</th>
                            <th>总托数</th>
                            <th>总件数</th>
                            <th>送货单号</th>

                        </tr>
                        </thead>
                        <tbody>
                        </tbody>
                    </table>

### css ###

.badao_hoverd {
        background-color: rgba(35,198,200,0.1);
    }
    
    table.dataTable tbody tr.selected {
      background-color: rgba(35,198,200,0.6);
    }

### jquery ###

//DataTable 行悬浮事件，用来设置样式悬浮事件
        $('#wmsReceiveOrder_table_id tbody').on('mouseover', 'tr', function () {
            if (!$(this).hasClass('badao_hoverd') ) {
                $(this).addClass('badao_hoverd');
            }
        } ).on('mouseleave', 'tr', function () {
            if ($(this).hasClass('badao_hoverd') ) {
                $(this).removeClass('badao_hoverd');
            }
        } );
        //DataTable 行点击事件，用来设置样式点击事件
      $('#wmsReceiveOrder_table_id tbody').on('click', 'tr', function () {
        if (!$(this).hasClass('selected') ) {
          t.$('tr.selected').removeClass('selected');
          $(this).addClass('selected');
        }
      } );
