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 } ] .......extjs样式覆盖app/resource/css/admin.css
主要覆盖了左侧导航菜单treelist和中间tabpanel的部分风格样式,
记得在app.html中extjs样式之后引入覆盖样式
