kendo grid keyup and sum列

Question

嗨，我是剑道网的初学者。在编辑模式下，一旦我的键入原来的价格和税额，我想马上结束最终价格。请参阅我的代码以低于

 <div class="panel-body"> 
       <div id="productRobPrice-grid"></div> 

       <script> 
        var record = 0;

           } 
           ], 
           width: 200 
          } 
          ] 
         }); 
        }); 
       </script> 
      </div> 

，但目前有一个问题，原价文本 KEYUP似乎无法开火。请给一些指导。 TQ

要将功能附加到keyup事件，您需要创建custom editor function。

<div id="grid"></div> 
<script> 
    $("#grid").kendoGrid({ 
     columns: [{ 
       field: "name" 
      }, { 
       field: "price", 
       editor: function(container, options) { 
        // create an input element 
        var input = $("<input/>"); 
        // set its name to the field to which the column is bound ('name' in this case) 
        input.attr("name", options.field); 
        input.keyup(function() { 
         alert("key up"); 
        }); 
        // append it to the container 
        input.appendTo(container); 
        // initialize a Kendo UI AutoComplete 
        input.kendoNumericTextBox(); 
       } 
      }, 
      { 
       command: "edit" 
      } 
     ], 
     editable: true, 
     dataSource: [{ 
      name: "Jane Doe", 
      price: 5 
     }, { 
      name: "John Doe", 
      price: 10 
     }], 
     editable: { 
      mode: "inline" 
     } 
    }); 
</script> 

但我想你可能需要像this之类的东西。一个聚合函数，将重新计算其变化值。不如keyup立即，但应该为你工作。
