ExtJs layout
extjs的容器组件都可以设置它的显示风格，它的有效值有 absolute, accordion, anchor, border, card, column, fit, form and table. 一共9种。简单总结一下，帮助记忆。
[list]
Java代码
Ext.onReady(function(){
var bd = Ext.getBody();
var panel = new Ext.Panel(//Ext.formPanel就是Panel中用了form布局
{
renderTo: bd,
title: 'uu',
layout: 'accordion',
width: 500,
height: 200,
layoutConfig: {
animate: false
},
items: [{
title: '元素1',
html: ''
}, {
title: '元素2',
html: ''
}, {
title: '元素3',
html: ''
}, {
title: '元素4',
html: ''
}]
});
}); 1.容器内的组件要么指定宽度，要么在anchor中同时指定高/宽，
2.anchor值通常只能为负值(指非百分比值)，正值没有意义，
3.anchor必须为字符串值
