在下面的代码中,我的menuItem1
对象的单击事件中,如何更改renderContent
对象的html内容,以便当用户单击菜单项的标题时,页面中间的内容会发生变化?如何从extJS点击事件中访问其他extJS对象?
(在所有的例子我看,单击事件正在创建新的对象,但不改变现有对象。)
Ext.onReady(function(){
var menuItem1 = new Ext.Panel({
id: 'panelStart',
title: 'Start',
html: 'This is the start menu item.',
cls:'menuItem'
});
var menuItem2 = new Ext.Panel({
id: 'panelApplication',
title: 'Application',
html: 'this is the application page',
cls:'menuItem'
});
var regionMenu = new Ext.Panel({
region:'west',
split:true,
width: 210,
layout:'accordion',
layoutConfig:{
animate:true
},
items: [ menuItem1, menuItem2 ]
});
var regionContent = new Ext.Panel({
region: 'center',
padding:'10',
autoScroll: true,
html: 'this is the content'
});
new Ext.Viewport({
layout: 'border',
items: [ regionMenu, regionContent ]
});
menuItem1.header.on('click', function() {
alert('this appears in alert window');
// regionContent.set('html', 'new text'); //nothing appears, no error
// regionContent.set('html', 'new text'); //nothing appears, no error
// Ext.get('regionContent').html = 'new text'; //error: "regionContent is null"
// Ext.getCmp('contentArea').html = 'the new text'; //nothing appears, no error
// Ext.getCmp('contentArea').set('html', 'new text'); //error: "set is not a function"
});
});
