ExtJs 4 grid 批量删除 获取选中行ID

重点是标记出来的地方，不解释。

            itemId: 'btnRemove',
            text: '删除用户',
            iconCls: 'delete',
            disabled: true,
            handler: function () {
                
                var selModel = grid.getSelectionModel();
                if (selModel.hasSelection()) {
                    Ext.Msg.confirm("警告", "确定要删除吗？", function (button) {
                        if (button == "yes") {
                            var selected = selModel.getSelection();
                            var Ids = []; //要删除的id
                            Ext.each(selected, function (item) {
                                Ids.push(item.data.Id);
                            })
                          //  alert(Ids);

                        }
                    });
                }
                else {
                    Ext.Msg.alert("错误", "没有任何行被选中，无法进行删除操作！");
                }
            }

ExtJs4 Ajax 删除操作

//************批量删除管理员操作****************//
    function Delete_Data(ids) {
        Ext.MessageBox.show({
            msg: '正在请求数据, 请稍侯',
            progressText: '正在请求数据',
             300,
            wait: true,
            waitConfig: { interval: 10 }
        });
       // Ext.Ajax.defaultPostHeader = 'FTchinaMVC/json'; //仅传递ids数组即可，无需转换为json
        Ext.Ajax.request({
            url: '/master/DeleteModels',
            method: "post",
            success: function (response, opts) {
                Ext.MessageBox.hide();
                if (response.responseText) {
                    store.load();
                    Ext.Msg.alert('系统提示', "删除成功");
                } else {
                    Ext.Msg.alert("系统提示", '删除失败');
                }
            },
            failure: function () {
                Ext.Msg.alert('系统提示', '系统出错！');
            },
            params: {ids:ids}
        });
    }

增加一个自定义的Action，接受传递过来的Ids

        [HttpPost]
        public ActionResult DeleteModels(string[] ids)
        {
            foreach (string id in ids)
            {
                Master master = db.Master.Find(int.Parse(id));
                db.Master.Remove(master);
                db.SaveChanges();
            }
            return this.JsonFormat(new ExtResult { success = true });
        }
