我有一个窗口,当单击某个单元格时,会在弹出窗口中显示有关用户的值。在我的UserController中,我根据id加载用户的json,是否有任何方法可以将此json的特定值传递到我的窗户?我知道如果它是一个表单,我可以使用.getForm()。setValues()。我可以在窗口中嵌套表格吗?
Controller snippet:
loadUserDetails: function(userId) {
var view = Ext.widget('userdetails').show();
Ext.Ajax.request({
url: /user/get.htm?alt=json',
params: { id: userId },
success: function(response) {
var json = Ext.JSON.decode(response.responseText);
}
});
}
查看摘录(窗口):
Ext.define('App.view.user.UserDetails', {
extend: 'Ext.window.Window'
,alias: 'widget.userdetails'
,id: 'userdetails'
,title: 'User Details'
,height: 300
,width: 380
,initComponent: function() {
var me = this;
this.items = [{
xtype: 'fieldset',
title: 'Information',
margin: '5',
width: 350,
height: 250,
defaults: {xtype: 'displayfield', margin: '3', labelWidth: 100, width: 300},
items: [{
id: 'id',
width: 150,
fieldLabel: 'User Id'
},{
id: 'email',
width: 250,
fieldLabel: 'User Email'
}]
}];
this.callParent(arguments);
}
});

鉴于此课程:
Ext.define('App.view.user.UserDetails', {
extend: 'Ext.window.Window'
,alias: 'widget.userdetails'
,id: 'userdetails'
,title: 'User Details'
,height: 300
,width: 380
,items: [{
xtype: 'fieldset',
title: 'Information',
margin: '5',
width: 350,
height: 250,
defaults: {xtype: 'displayfield', margin: '3', labelWidth: 100, width: 300},
items: [{
// you should avoid using fixed id that will prevent using the component
// multiple times
// id: 'id',
width: 150,
fieldLabel: 'User Id'
,itemId: 'userId' // <= add item id for easy retrieval
},{
// id: 'email',
width: 250,
fieldLabel: 'User Email'
,name: 'userEmail' // <= or a name, as is logical for a field
}]
}]
});
您可以使用component queries获取字段的引用并设置其值:
var win = Ext.create('App.view.user.UserDetails', {
autoShow: true
});
// query by itemId
win.down('#userId').setValue(123);
// or by name
win.down('field[name=userEmail]').setValue('user@example.com');
或者您可以在窗口中嵌套表单,以便使用setValues
(以及其他表单功能):
Ext.define('App.view.user.UserDetails', {
extend: 'Ext.window.Window'
,alias: 'widget.userdetails'
,id: 'userdetails'
,title: 'User Details'
,height: 300
,width: 380
,layout: 'fit'
,items: [{
xtype: 'form'
,items: [{
xtype: 'fieldset',
title: 'Information',
margin: '5',
width: 350,
height: 250,
defaults: {xtype: 'displayfield', margin: '3', labelWidth: 100, width: 300},
items: [{
width: 150,
fieldLabel: 'User Id'
// name is required for setValues to work
,name: 'userId'
},{
// id: 'email',
width: 250,
fieldLabel: 'User Email'
,name: 'userEmail'
}]
}]
}]
});
var win = Ext.create('App.view.user.UserDetails', {
autoShow: true
});
win.down('form').setValues({
...
});
