    经过前面几篇文章的介绍，一个基本的MVC结构应该是具备了。而且上一篇文章中，也已经实现了一个基本的用户管理列表页面。接着上一篇，完善用户管理，实现增删改。为了用户体验，增加和修改用户信息的表单，都放在弹窗中进行。避免跳转页面。

    定义用户增加窗口:app/luter/view/sys/user/UserAdd.js

    Ext.define('luter.view.sys.user.UserAdd', {
    extend: 'Ext.window.Window',//扩展window组件
    alias: 'widget.useraddview',
    requires: [],
    constrain: true,//约束窗体弹出，别出浏览器可视范围
    modal: true,//模态
    maximizable: true,//可以最大化
    iconCls: baseConfig.appicon.add,//图标
    layout: "fit",//自适应布局
    width: 700,
    autoHeight: true,//自适应高度
    viewModel: {
        data: {
            title: ''
        }
    },
    bind: {
        title: '新增用户:  ' + '{title}'//绑定这个空间的title属性上
    },
    initComponent: function () {
        var me = this;
        //加入一个表单，表单内元素通过loadView方法添加
        me.items = [{
            xtype: 'form',
            width: 700,
            autoHeight: true,
            fieldDefaults: {
                labelAlign: 'right',
                labelStyle: 'font-weight:bold;'
            },
            border: false
        }]
        //操作按钮直接加载window上
        me.buttons = ['->', {
            text: '新增',
            cls: 'green-btn',
            iconCls: baseConfig.appicon.add,
            handler: function () {
                var form = this.down('form');
                if (form.isValid()) {
                    form.submit({
                        url: 'sys/user/add',
                        method: 'POST',
                        waitTitle: "提示",
                        waitMsg: '正在提交数据，请稍后 ……',
                        success: function (form, action) {//添加成功后提示消息，并且刷新用户列表数据
                            me.close();
                            DealAjaxResponse(action.response);
                            Ext.data.StoreManager.lookup('UserStore').load();
                        },
                        failure: function (form, action) {
                            DealAjaxResponse(action.response);
                        }
                    });
                } else {
                    toast({
                        msg: '表单填写错误，请确认'
                    })
                }
            },
            scope: this
        }, '-', {
            text: '放弃',
            cls: 'red-btn',
            iconCls: baseConfig.appicon.undo,
            handler: function () {
                me.close();
            },
            scope: this
        }]
        me.callParent(arguments);
    },
    //form表单的渲染在这里完成，目的是可以通过创建操作传入参数
    loadView: function (config) {
        var formCmp = this.getComponent(0);
        formCmp.add([{
            columnWidth: 1,
            layout: "form",
            items: [{
                xtype: "textfield",
                fieldLabel: baseConfig.model.user.username,
                name: 'username',
                maxLength: 250,
                maxLengthText: '请输入{0}个字以内',
                emptyText: '登录用的用户名',
                bind: '{title}',//mvvm数据绑定，输入的时候同步就显示在win的title上了
                allowBlank: false,
                flex: 1
            },
                {
                    xtype: "textfield",
                    fieldLabel: baseConfig.model.user.real_name,
                    name: 'real_name',
                    maxLength: 10,
                    maxLengthText: '请输入{0}个字以内',
                    emptyText: '真实姓名',
                    allowBlank: false,
                    flex: 1
                }

            ]

        }]);

    }
});

    添加用户的触发动作是在用户列表页面的添加按钮，所以，还需要修改一下用户列表页面里对应位置，加入触发动作，如下：

    。。。。。

 me.dockedItems = [{
            xtype: 'toolbar',
            items: [{
                text: '添加',
                iconCls: baseConfig.appicon.add,
                tooltip: '添加',
                handler: function () {
                    //create的时候，js会动态加载进来。
                    var win = Ext.create('luter.view.sys.user.UserAdd', {
                        animateTarget: this//以这个按钮为锚点动画打开win
                    });
                    win.loadView();//给form加入元素，可以在这里传入一些参数给将要打开的添加页面
                    win.show();//显示这个窗体

                }
            }]
        }]
。。。。。。

    定义用户信息修改窗口:app/luter/view/sys/user/UserEdit.js

    
Ext.define('luter.view.sys.user.UserEdit', {
    extend: 'Ext.window.Window',//扩展window组件
    alias: 'widget.usereditview',
    requires: [],
    constrain: true,//约束窗体弹出，别出浏览器可视范围
    modal: true,//模态
    maximizable: true,//可以最大化
    iconCls: baseConfig.appicon.update,//图标
    layout: "fit",//自适应布局
    width: 700,
    autoHeight: true,//自适应高度
    initComponent: function () {
        var me = this;
        //加入一个表单，表单内元素通过loadView方法添加
        me.items = [{
            xtype: 'form',
            width: 700,
            autoHeight: true,
            fieldDefaults: {
                labelAlign: 'right',
                labelStyle: 'font-weight:bold;'
            },
            border: false
        }]
        //操作按钮直接加载window上
        me.buttons = ['->', {
            text: '新增',
            cls: 'green-btn',
            iconCls: baseConfig.appicon.add,
            handler: function () {
                var form = this.down('form');
                if (form.isValid()) {
                    form.submit({
                        url: 'sys/user/update',
                        method: 'POST',
                        waitTitle: "提示",
                        waitMsg: '正在提交数据，请稍后 ……',
                        success: function (form, action) {//添加成功后提示消息，并且刷新用户列表数据
                            me.close();
                            DealAjaxResponse(action.response);
                            Ext.data.StoreManager.lookup('UserStore').load();
                        },
                        failure: function (form, action) {
                            DealAjaxResponse(action.response);
                        }
                    });
                } else {
                    toast({
                        msg: '表单填写错误，请确认'
                    })
                }
            },
            scope: this
        }, '-', {
            text: '放弃',
            cls: 'red-btn',
            iconCls: baseConfig.appicon.undo,
            handler: function () {
                me.close();
            },
            scope: this
        }]
        me.callParent(arguments);
    },
    loadView: function (config) {
        var formCmp = this.getComponent(0);
        formCmp.add([{
            columnWidth: 1,
            layout: "form",
            items: [{
                xtype: "hidden",//这里放一个隐藏控件，因为是修改记录，所以必须提交ID
                name: 'id'
            }, {
                xtype: "textfield",
                fieldLabel: baseConfig.model.user.username,
                name: 'username',
                maxLength: 250,
                maxLengthText: '请输入{0}个字以内',
                emptyText: '登录用的用户名',
                allowBlank: false,
                flex: 1
            },
                {
                    xtype: "textfield",
                    fieldLabel: baseConfig.model.user.real_name,
                    name: 'real_name',
                    maxLength: 10,
                    maxLengthText: '请输入{0}个字以内',
                    emptyText: '真实姓名',
                    allowBlank: false,
                    flex: 1
                }

            ]

        }]);

    }
});

    我们希望在双击用户列表中的某一条记录(某个用户)的时候，弹出用户修改对话框，所以，修改用户列表页面代码，添加列表行双击事件的监听，如下：

    。。。。。。


me.listeners = {
            'itemdblclick': function (table, record, html, row, event, opt) {
                if (record) {
                    var id = record.get('id');
                    var view = Ext.create('luter.view.sys.user.UserEdit', {title: '编辑数据', animateTarget: this});
                    view.loadView();
                    //为了保证数据完整性，拿到这条数据的ID后，需要从后台获取当前这条数据，然后再修改
                    //对于后台而言，最好对数据设置@version功能，确保数据一致性。
                    loadFormDataFromDb(view, 'app/testdata/user.json');
                } else {
                    showFailMesg({
                        msg: '加载信息失败，请确认。'
                    })
                }

            }
        }

。。。。。。

    添加记录删除操作

    在用户列表中，设置action列,实现删除操作，如下:

    .......

 me.columns = [{
            xtype: 'rownumberer',
            text: '序号',
            width: 60
        }, {
            header: "操作",
            xtype: "actioncolumn",
            width: 60,
            sortable: false,
            items: [{
                text: "删除",
                iconCls: 'icon-delete',
                tooltip: "删除这条记录",
                handler: function (grid, rowIndex, colIndex) {
                    var record = grid.getStore().getAt(rowIndex);
                    if (!record) {
                        toast({
                            msg: '请选中一条要删除的记录'
                        })
                    } else {
                        showConfirmMesg({
                            message: '确定删除这条记录?',
                            fn: function (btn) {
                                if (btn === 'yes') {
                                    showToastMessage('啥意思?');//测试一下而已，实际情况是执行ajax删除，如下。
                                    // Ext.Ajax.request({
                                    //     url: 'sys/user/delete',
                                    //     method: 'POST',
                                    //     params: {
                                    //         id: record.get('id')
                                    //     },
                                    //     success: function (response, options) {
                                    //         DealAjaxResponse(response);
                                    //         Ext.data.StoreManager.lookup('UserStore').load();
                                    //     },
                                    //     failure: function (response, options) {
                                    //         DealAjaxResponse(response);
                                    //     }
                                    // });
                                } else {
                                    Ext.toast({
                                        title:'看...',
                                        width:200,
                                        html: '不删了.....'
                                    });
                                    return false;
                                }
                            }

                        })

                    }

                }
            }]
        }, {
            header: baseConfig.model.user.id,
            dataIndex: 'id',
            hidden: false,
            flex: 1
        },

            {
                header: baseConfig.model.user.username,
                dataIndex: 'username',
                flex: 1
            },
            {
                header: baseConfig.model.user.real_name,
                dataIndex: 'real_name',
                flex: 1
            }
        ]
