关于MVC工厂模式的增删改查sql存储过程

这里MVC中用到了反射,工厂,泛型,接口

在搭建框架的时候,除了MVC的三层以外,还有泛型的接口层和工厂层

下面是dal层调用sql存储过程,增删改查,dal层继承了接口层,实现了接口层里面的方法

  1 namespace DAL

 这是controller与前台交互,控制器里面的方法需要注意的是下拉的绑定,还有分部视图的使用

我用的是强类型视图,所以视图页面和控制器里面参数的变量名要一致,否则控制器中的方法接受不到值的

 这里需要说一下,jquery写的全选和批删的方法,详情看代码

 <script>
//全选
        $(function () {
            $("#CheckAll").click(function () {
                if (this.checked) {
                    $("input[name='check']").each(function () {
                        this.checked = true;
                    })
                }

                else {
                    $("input[name='check']:checked").each(function () {
                        this.checked = false;
                    })
                }

            })
        })
        function DelAll() {
            var check = [];
            $("input[name='check']:checked").each(function () {
                check.push($(this).val());
            })
            if (check == 0) {
                alert("请先进行选择");
            }
            else {
                $.ajax({
                    type: "post",
                    url: "/house/deleteall",
                    data: { id: check.toString() },
                    success: function (a) {
                        if (a > 0) {
                            alert("批量删除成功!");
                            location.reload();
                        }
                    }
                })
            }

        }
    </script>

基本的页面布局,这里就不展示了,

还需要说的就是使用强类型视图,在修改的时候,

需要使用@html.Hidden("Id")
