如何将使用 Ext.create 添加的对象添加到我的视口中?
How can I add an object that is added with Ext.create to my Viewport?
我是 Ext JS 的新手,我需要在我的视口中添加一个按钮。
我试过将它添加为一个项目,但是当我点击它时它不起作用:
items: [ {
xtype: 'datepicker',
width: 211
},
{
xtype: 'datepicker',
width: 211
},
{
xtype: 'button',
text: 'Search',
width: 211
},
],
那么,在官方documentation我找到了另一种添加方式:
Ext.create('Ext.Button', {
text : 'Button',
renderTo : Ext.getBody(),
listeners: {
click: function() {
// this == the button, as we are in the local scope
this.setText('I was clicked!');
},
mouseover: function() {
// set a new config which says we moused over, if not already set
if (!this.mousedOver) {
this.mousedOver = true;
alert('You moused over a button!\n\nI wont do this again.');
}
}
}
});
但我希望它位于我在视口中定义的西部区域,但我不知道如何实现这一点,因为我是 Ext JS 的新手。
我的代码:
function init() {
Ext.application({
name: 'MyApp',
launch: function() {
Ext.create('Ext.data.Store', {
storeId:'prices',
fields:['name', 'priceNight', 'totalPrice', 'Check-in', 'Check-out'],
data:{'items':[
]},
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'
}
}
});
Ext.create('Ext.container.Viewport', {
layout: 'border',
items: [{
title: 'West',
region: 'west',
margins: '0 5 0 5',
flex: .3,
collapsible: true,
split: true,
titleCollapse: true,
items: [
{
xtype: 'datepicker',
width: 211
},
{
xtype: 'datepicker',
width: 211
},
{
//I want the button here.
},
],
}, {
title: 'Center',
region: 'center',
collapsible: false,
items: {
// I want to add it just there
xtype: 'grid',
store: Ext.data.StoreManager.lookup('prices'),
columns: [
],
}
}]
});
}
});
}
我想要这里的按钮:
有什么想法吗?
提前致谢!
我刚刚知道怎么做了!我将post 在这里做我所做的,也许它会对某些人有所帮助:
很简单,用一个变量调用就可以了。
按钮代码:
var button = Ext.create('Ext.Button', {
text : 'Button',
renderTo : Ext.getBody(),
listeners: {
click: function() {
// this == the button, as we are in the local scope
this.setText('I was clicked!');
},
mouseover: function() {
// set a new config which says we moused over, if not already set
if (!this.mousedOver) {
this.mousedOver = true;
alert('You moused over a button!\n\nI wont do this again.');
}
}
}
});
在您的视口中,您只需将其添加为一个项目:
...
items: [
{
items: button //button is the variable that we defined when we created the button
}
]
...
最终结果:
我希望这对和我有同样问题的人有所帮助:)
