jQuery easyUI datagrid 增加求和统计行的实现代码

<style type="text/css">

    .subtotal { font-weight: bold; }/合计单元格样式/
  </style>
  <script type="text/javascript">
    function onLoadSuess() {
      //添加“合计”列
      $('#table').datagrid('appendRow', {
        Saler: '<span class="subtotal">合计</span>',
        TotalOrderCount: '<span class="subtotal">' + pute("TotalOrderCount") + '</span>',
        TotalOrderMoney: '<span class="subtotal">' + pute("TotalOrderMoney") + '</span>',
        TotalOrderScore: '<span class="subtotal">' + pute("TotalOrderScore") + '</span>',
        TotalTrailCount: '<span class="subtotal">' + pute("TotalTrailCount") + '</span>',
        Rate: '<span class="subtotal">' + ((pute("TotalOrderScore") / pute("TotalTrailCount"))  100).toFixed(2) + '</span>'
      });
    }
    //指定列求和
    function pute(colName) {
      var rows = $('#table').datagrid('getRows');
      var total = 0;
      for (var i = 0; i < rows.length; i++) {
        total += parseFloat(rows[i][colName]);
      }
      return total;
    }
  </script>
