如何使用JQuery在模式中编辑表

如何解决如何使用JQuery在模式中编辑表

NET MVC并在更新表时遇到问题。让我向您解释我的关注。我创建了一个包含四个产品项的采购订单,并将其保存在数据库中。现在,我想编辑该特定采购订单中的某些项目,但是我无法执行此操作。我从最近8个小时开始面临这个问题。基本上,整个概念取决于JQuery。因此,我请您帮助我,对此我将非常感谢。

<form name="EditpurchaseForm" id="EditpurchaseForm">

        }
        }
</script>

在这种情况下,我没有获得OrderID。请帮我。 这是编辑页面图像。我正在获取表中的所有项目详细信息。如果我进行了任何更改,它将不会保存在我的数据库中。

This is Edit Page Image. I am getting all the item details in the table. If i made any change it will not save in my database.
