extjs 3.1 组件使用

博客分类：

EXT CSS HTML JavaScript Ajax

Ext.Window

使用new Ext.Window()，创建一个表格则使用new Ext.GridPanel()。当然，除了一些普通的组件以外，一般都会在构造函数中通过传递构造参数来创建组件。

<%@ page language="java" contentType="text/html; charset=GBK"
 pageEncoding="GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
  <meta http-equiv="Content-Type" content="text/html; charset=GBK">
  <title>formpanel</title>
 <link rel="stylesheet" type="text/css"
   href="<%=request.getContextPath()%>/css/ext2/ext-all.css" />

</style>

var w=new Ext.Window({
           contentEl:"win",//主体显示的html元素，也可以写为el:"win"
           width:300,
           height:200,
           title:"标题"
        });
        w.show();

});
</script>

    </head>
    <body>

        <div id="win" ></div>
    </body>
</html>

//几个前面没有介绍的window自己的配置参数
1.closeAction:枚举值为：close(默认值)，当点击关闭后，关闭window窗口
hide,关闭后，只是hidden窗口
2.closable:true在右上角显示小叉叉的关闭按钮，默认为true
3.constrain：true则强制此window控制在viewport，默认为false
4.modal:true为模式窗口，后面的内容都不能操作，默认为false
5.plain：//true则主体背景透明，false则主体有小差别的背景色，默认为false

//需要显示下show（）方法,默认的窗口是可拖动的，可关闭的，可拖动大小的
w.show（）

Ext.TabPanel

Ext.TabPanel这个东西是最常用的组件之一，它继承自Ext.Panel。因为继承自Ext.Panel，所以，它也是由header、tbar、body、bbar、footer这几个部分构成。
