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
