EXTJS :TreePanel 单击以更改设置项
大家好 我是 extjs 的初学者,当我单击其中一个节点时,我在更改/将项目设置为布局时遇到问题。
这里是我的 contentPanel:
var contentPanel = {
id: 'content-panel',
region: 'center', // this is what makes this panel into a region within the containing layout
layout: 'card',
margins: '2 5 5 0',
activeItem: 0,
border: false,
items: layoutExamples // HERE I WANT TO CHANGE DYNAMIC
};
我的树节点上的“监听器”:
treePanel.getSelectionModel().on('select', function(selModel, record) {
if (record.get('leaf')) {
//Ext.getCmp('content-panel').layout.setActiveItem(record.getId() + '-panel'); <== It's work.
Ext.getCmp('content-panel').setActive(formPanel); // HERE I TRY TO CHANGE ITEM ON CLICK AND SET FORMPANEL
});
我的测试项目:
var formPanel = Ext.create('Ext.form.Panel', {
frame: true,
title: 'Form Fields',
width: 340,
bodyPadding: 5,
fieldDefaults: {
labelAlign: 'left',
labelWidth: 90,
anchor: '100%'
},
items: [{
xtype: 'textfield',
name: 'textfield1',
fieldLabel: 'Text field',
value: 'Text field value'
}, {
xtype: 'textfield',
name: 'password1',
inputType: 'password',
fieldLabel: 'Password field'
}, {
xtype: 'filefield',
name: 'file1',
fieldLabel: 'File upload'
}, {
xtype: 'textareafield',
name: 'textarea1',
fieldLabel: 'TextArea',
value: 'Textarea value'
} }]
});
所以,我的目标是当我单击节点时更改我的内容面板的项目..!
非常感谢各位朋友的帮助!
Hi everybody
I'm a beggining with extjs and I have issue with change / set a item to a layout when i click on one of my node .
Here my contentPanel :
var contentPanel = {
id: 'content-panel',
region: 'center', // this is what makes this panel into a region within the containing layout
layout: 'card',
margins: '2 5 5 0',
activeItem: 0,
border: false,
items: layoutExamples // HERE I WANT TO CHANGE DYNAMIC
};
My "listener" on my treenode :
treePanel.getSelectionModel().on('select', function(selModel, record) {
if (record.get('leaf')) {
//Ext.getCmp('content-panel').layout.setActiveItem(record.getId() + '-panel'); <== It's work.
Ext.getCmp('content-panel').setActive(formPanel); // HERE I TRY TO CHANGE ITEM ON CLICK AND SET FORMPANEL
});
My item for test :
var formPanel = Ext.create('Ext.form.Panel', {
frame: true,
title: 'Form Fields',
width: 340,
bodyPadding: 5,
fieldDefaults: {
labelAlign: 'left',
labelWidth: 90,
anchor: '100%'
},
items: [{
xtype: 'textfield',
name: 'textfield1',
fieldLabel: 'Text field',
value: 'Text field value'
}, {
xtype: 'textfield',
name: 'password1',
inputType: 'password',
fieldLabel: 'Password field'
}, {
xtype: 'filefield',
name: 'file1',
fieldLabel: 'File upload'
}, {
xtype: 'textareafield',
name: 'textarea1',
fieldLabel: 'TextArea',
value: 'Textarea value'
} }]
});
So, my objective is to change item of my content panel when i click on a node.. !

尝试一下并在评论中告诉我:
在您的事件中,基于 http://docs.sencha.com/ext-js/4-0/#/api/Ext.layout.container.Card-method-setActiveItem :
通过方式,在您提供的代码中,侦听器中存在错误,它缺少用于关闭 if 的 }!
try that and tell me in the comments:
And in your event, based on http://docs.sencha.com/ext-js/4-0/#/api/Ext.layout.container.Card-method-setActiveItem :
By the way, in the code you provided, there is an error in the listener, it misses a } for closing the if!
