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]- absolute 顾名思义,在容器内部,根据指定的坐标定位显示
- accordion 这个是最容易记的,手风琴效果
- anchor 这个效果具体还不知道有什么用,就是知道注意一下
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
- border 将容器分为五个区域:east,south,west,north,center
- card 像安装向导一样,一张一张显示
- column 把整个容器看成一列,然后向容器放入子元素时
- fit 一个子元素将充满整个容器(如果多个子元素则只有一个元素充满整个容器)
- form 是一种专门用于管理表单中输入字段的布局
- table 按照普通表格的方法布局子元素,用layoutConfig:{columns:3},//将父容器分成3列
[list]
- Ext.OnReady(function(){
- var panel=new Ext.Panel(//Ext.formPanel就是Panel中用了form布局

- renderTo:'paneldiv',
