我在 Extjs 中创建了 3 个面板、2 个按钮(上一个、下一个)并添加到视口。一次只能看到一个面板(默认情况下是第一个面板)。单击下一个按钮时,它应该显示下一个面板,然后如果我单击“上一个”按钮,它应该显示上一个面板。
现在我已经为面板编写了一个代码,它的工作原理是,面板不能正确地左右导航。
这是我的代码:
Ext.application({
name: 'HelloExt',
requires: [
'Ext.util.Point'
],
launch: function() {
var button =Ext.create('Ext.Button', {
text: 'Toggle Containers',
handler: function () {
if (this.clickCount==1) {
containerPanel1.getEl().scrollRight;
containerPanel2.getEl().slideIn('t', 'toggle');
this.clickCount=2;
} else {
this.clickCount = 1;
containerPanel1.getEl().slideIn('t', 'toggle');
containerPanel2.getEl().scrollLeft;
}
},
renderTo: Ext.getBody()
});
var containerPanel1 = Ext.create('Ext.panel.Panel', {
renderTo: Ext.getBody(),
draggable: {
insertProxy: false,
startDrag: function(e) {
var el = Ext.get(this.getEl());
el.dd = new Ext.dd.DDProxy(el.dom.id, 'group');
this.x = el.getLeft(true);
this.y = el.getTop(true);
},
afterDrag: function(e) {
this.x = el.getLeft(true);
this.y = el.getTop(true);
this.fireEvent('itemdrag', this);
}
},
width:400,
height:550,
layout: 'column',
bodyStyle:{'background-color':'blue'},
margin:'30 0 0 20',
suspendLayout: true ,
defaults :{
xtype: 'panel',
margin:'30 0 0 0',
height: 450,
columnWidth: 0.2
},
items: [
{
html: 'Child Panel 1',
},
{
html: 'Child Panel 2',
},
{
html: 'Child Panel 3',
},
{
html: 'Child Panel 4',
},
{
html: 'Child Panel 5',
}
]
});
containerPanel1.draggable;
var containerPanel2 = Ext.create('Ext.panel.Panel', {
renderTo: Ext.getBody(),
draggable: {
insertProxy: false,
startDrag: function(e) {
var el = Ext.get(this.getEl());
el.dd = new Ext.dd.DDProxy(el.dom.id, 'group');
this.x = el.getLeft(true);
this.y = el.getTop(true);
},
afterDrag: function(e) {
this.x = el.getLeft(true);
this.y = el.getTop(true);
this.fireEvent('itemdrag', this);
}
},
width:400,
height:550,
layout: 'column',
bodyStyle:{'background-color':'green'},
margin:'30 0 0 20',
suspendLayout: true ,
defaults :{
xtype: 'panel',
margin:'30 0 0 0',
height: 300,
columnWidth: 0.2
},
items: [
{
html: 'Child Panel 1',
},
{
html: 'Child Panel 2',
},
{
html: 'Child Panel 3',
},
{
html: 'Child Panel 4',
},
{
html: 'Child Panel 5',
}
]
});
containerPanel2.draggable;
containerPanel2.getEl().hide();
Ext.create('Ext.container.Viewport', {
layout: 'column',
items: [containerPanel1,containerPanel2,button]
});
}
});
请帮助我..谢谢
