我有一个带有三个面板的 ExtJS 4.2.1 手风琴布局。
当应用程序首次启动时,第一个面板打开,第二个/第三个面板关闭。
我可以打开和关闭第二个和第三个面板,但我永远无法关闭第一个面板。
Ext.define('MyAccordion', {
extend: 'Ext.container.Container',
alias: 'widget.myAccordion',
padding: 0,
margin: 0,
width: 200,
layout: {
type: 'accordion',
align: 'stretch',
animate: true,
hideCollapseTool: true
},
items: [{
xtype: 'panel',
title: 'Test Volumes',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'label',
text: 'volume one'
},{
xtype: 'label',
text: 'volume two'
},{
xtype: 'label',
text: 'volume three'
}]
}, {
xtype: 'panel',
title: 'Production Volumes',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'label',
text: 'volume one'
},{
xtype: 'label',
text: 'volume two'
},{
xtype: 'label',
text: 'volume three'
}]
}, {
xtype: 'panel',
title: 'Extra Volumes',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'label',
text: 'volume one'
},{
xtype: 'label',
text: 'volume two'
},{
xtype: 'label',
text: 'volume three'
}]
}]
});
在以下来自 4.2.1 示例布局浏览器示例的代码中,如果启动应用程序后所做的第一件事是单击第一个标头,则它会关闭,但随后重新打开它,并且它永远不会再次关闭:
Ext.onReady(function() {
Ext.create('Ext.container.Viewport', {
renderTo: Ext.getBody(),
items: [{
xtype: 'panel',
title: 'Accordion Layout',
layout: 'accordion',
defaults: {bodyStyle: 'padding:15px'},
items: [{
title: 'Introduction',
tools: [{type:'gear'},{type:'refresh'}],
html: '<p>Here is some accordion content. Click on one of the other bars below for more.</p>'
},{
title: 'Basic Content',
html: '<br /><br /><p>More content. Open the third panel for a customized look and feel example.</p>',
items: {
xtype: 'button',
text: 'Show Next Panel',
handler: function(){
Ext.getCmp('acc-custom').expand(true);
}
}
},{
id: 'acc-custom',
title: 'Custom Panel Look and Feel',
cls: 'custom-accordion', // look in layout-browser.css to see the CSS rules for this class
html: '<p>Here is an example of how easy it is to completely customize the look and feel of an individual panel simply by adding a CSS class in the config.</p>'
}]
}]
});
});
更奇怪的是,如果我确实显示折叠/展开工具,第一个面板的工具就会停止工作。
