我正在研究extjs4,我的情况是: Extjs mvc用于构建我的应用程序,viewport是我应用程序的最顶层容器,west region是树,center区域是tabpage容器,当单击树项时,将创建具有特定内容的新页面。然后在这个页面中,我弹出一个模型窗口,这个模型窗口只是掩盖页面,而不是整个视口,这样我仍然可以单击树项打开另一个新页面。 我已经实现了这个,但是有一个问题,如果我已经在选项卡中打开了一个模型窗口,然后我切换到另一个选项卡然后返回,模型窗口被隐藏,但是我仍然希望该窗口显示我是否没有关闭它。任何人都可以帮助我,除了在tabpage中使用ifram之外还有更好的方法吗?
app.js:
Ext.application({
name: 'SysOpv',
appFolder: '/Js/AppSysOpv/app',
autoCreateViewport: true,
controllers: [
'Category',
'Band'
]
});
视口:
Ext.define('SysOpv.view.Viewport', {
extend: 'Ext.container.Viewport',
layout: 'fit',
initComponent: function() {
this.items = {
dockedItems: [{
dock: 'top',
xtype: 'toolbar',
height: 80,
items: [
{ xtype: 'component', html: 'setup' }
]
}],
layout: {
type: 'hbox',
align: 'stretch'
},
items: [{
width: 250,
xtype: 'categorytree'
}, {
id: 'maintabpanel',
flex: 1,
xtype: 'tabpanel'
}]
};
this.callParent(arguments);
}
});
树视图:
Ext.define('SysOpv.view.category.Tree', {
extend: 'Ext.tree.Panel',
alias: 'widget.categorytree',
title: 'setup',
rootVisible: false,
useArrows: true,
hideHeaders: true,
columns: [{
flex: 1,
xtype: 'treecolumn',
text: 'Name',
dataIndex: 'name'
}],
store: 'Category',
initComponent: function() {
this.callParent(arguments);
}
});
窗口视图:
Ext.define('SysOpv.view.edit.Band', {
extend: 'Ext.window.Window',
alias: 'widget.editband',
title: 'Setup',
layout: 'fit',
constrain: true,
modal: true,
initComponent: function() {
this.items = [{
xtype: 'form',
bodyPadding: 10,
items: [{
xtype: 'textfield',
name: 'name',
fieldLabel: 'Name'
}]
}];
this.buttons = [{
text: 'Save',
action: 'save'
}, {
text: 'Cancel',
scope: this,
handler: this.close
}];
this.callParent(arguments);
}
});
树控制器:
Ext.define('SysOpv.controller.Category', {
extend: 'Ext.app.Controller',
models: [ 'Category' ],
stores: [ 'Category' ],
views: [ 'category.Tree' ],
init: function() {
this.control({
'categorytree': {
itemdblclick: this.onTreeItemdblclick
}
});
},
onTreeItemdblclick: function (tree, record, item, index, e, eOpts) {
var mainTabs = Ext.getCmp('maintabpanel');
var tabId = record.get('id');
if (mainTabs) {
var checkTab = mainTabs.getComponent(tabId);
if (checkTab) {
mainTabs.setActiveTab(checkTab);
} else {
var controller;
var list;
switch (tabId) {
case '0101':
list = Ext.widget('listband');
break;
}
if (list)
{
var tabPage = mainTabs.add({
id: record.get('id'),
title: record.get('name'),
closable: true,
layout: 'fit',
items: [ list ]
});
mainTabs.setActiveTab(tabPage);
}
}
}
}
});
模块控制器:
Ext.define('SysOpv.controller.Band', {
extend: 'Ext.app.Controller',
models: [ 'Band' ],
stores: [ 'Band' ],
views: [ 'list.Band', 'edit.Band' ],
init: function() {
this.control({
'listband button[action=edit]': {
click: this.onEdit
}
});
},
onEdit: function(button, e, eOpts) {
var edit = Ext.widget('editband');
var list = button.up('gridpanel');
if (list.getSelectionModel().hasSelection()) {
var record = list.getSelectionModel().getLastSelected();
// I use renderTo here but have no effect,
// so I search in the google find a way to show the window in tab,
// and not mask all the viewport.
button.up('#0101').add(edit);
edit.down('form').loadRecord(record);
edit.show();
} else {
console.log('Not selected');
}
}
});
答案 0 :(得分:1)
以下是示例解决方案:
Ext.create('Ext.TabPanel', {
renderTo: 'container',
items: [
{
title: 'Tab 1',
itemId: 'tab1',
items: [
{ xtype: 'button', text: 'Show window', handler: function(){
var tab = this.up('#tab1'); // Find tab
var win = Ext.widget('editband'); // Find window
this.up('tabpanel').showWindow(tab, win);
} }
]
},
],
showWindow: function(tab, w){
tab.add(w);
tab.popup = w;
w.on('close', function() { // clean up after window close
delete this.popup;
}, tab, { single: true });
w.show();
},
listeners: {
tabchange: function(panel, tab) {
if (tab.popup !== undefined) { // show window after tab change
tab.popup.show();
}
}
}
});
基本上我已经为tabchange
事件创建了事件处理程序,我在其中重新显示了窗口。
