我是 EXTjs 的新手(也是 Stackoverflow 的新手)。我一直在努力解决这个问题,最后决定寻求帮助。我的问题是“如何同步组合框和文本字段的值。即如何从文本字段的‘存储’加载不同的值,而我正在更改组合框的值?”我的问题是,当我在组合框上加载值并选择它们时,我的文本字段一直为空。我试过“Ext.getCmp().setValue();” 它适用于此,但我认为如果我有 100 个文本字段,这不是最佳选择。我希望组合框和文本字段以某种方式与商店同步。任何帮助表示赞赏。图片中的情况在下面的链接中:
我的代码:
我的 app.js :
Ext.Loader.setConfig({
enabled: true
});
Ext.application({
name: 'work',
appFolder: 'app',
controllers: ['Work'],
launch: function() {
Ext.create('Ext.container.Viewport', {
//layout: 'fit',
items: [{
xtype: 'rightpanel' // gets it from view class
}
]
});
}
});
我的观点 RightPanel :
Ext.define('work.view.works.RightPanel', {
extend: 'Ext.panel.Panel',
ALIAS: 'widget.rightpanel',
width: 300,
title: 'Building navigation',
animCollapse: true,
collapsible: true,
split: true,
minSize: 400,
maxSize: 400,
margins: '0 5 0 0',
//activeTab:1, tabPosition:'bottom',
initComponent: function() {
this.items = [{
xtype: 'form',
items: [{
xtype: 'combobox',
fieldLabel: 'BuildingID',
queryMode: 'local',
name: 'Bid',
displayField: 'Bid',
valueField: 'Bid',
id: 'Bid',
MODE: 'remote',
store: 'Work'
}, {
xtype: 'textfield',
fieldLabel: 'Address',
name: 'Address',
displayField: 'Address',
valueField: 'Address',
id: 'Address',
store: 'Work'
}]
}];
this.columns = [{
header: 'ID',
dataIndex: 'Bid',
flex: 1
}, {
header: 'Texts',
dataIndex: 'Address',
flex: 1
}];
this.callParent(arguments);
}
});
我的商店:
Ext.define('work.store.Work', {
extend: 'Ext.data.Store',
model: 'work.model.Work',
storeId: 'workstore',
id: 'workstore',
autoLoad: true,
proxy: {
type: 'ajax',
limitParam: undefined,
startParam: undefined,
paramName: undefined,
pageParam: undefined,
noCache: false,
api: {
read: 'data/showWork.php' // just a .php file that reads values from database and shows them on combobox
},
reader: {
type: 'json',
root: 'data',
successProperty: 'success'
},
writer: {
type: 'json',
root: 'data',
encode: true
}
}
});
我的模型类:
Ext.define('work.model.Work', {
extend: 'Ext.data.Model',
//idProperty: 'WorkID',
fields: [{
name: 'Bid',
type: 'int'
}, 'Address']
});
我的控制器:
Ext.define('work.controller.Work', {
extend: 'Ext.app.Controller',
stores: ['Work'],
models: ['Work'],
views: [
'works.RightPanel' // name comes from view class
],
init: function() {
console.log('Done');
this.control({
'viewport > rightpanel': {
render: this.test
},
'rightpanel combobox[id=Bid]': {
select: this.change
}
});
},
change: function(buttons) {
var values = this.getStore('Work').collect('Address', 'Address', false);
var win = buttons.up('rightpanel'); // gets the needed widget
var form = win.down('combobox'); // gets the needed form
var value = form.getValue(); // gets the value
console.log("value " + value);
}
});
