面我们写一个最简单的ExtJS应用,在hello.html文件中输入下面的代码:
<html xmlns="http://www.w3.org/1999/xhtml" > <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>ExtJS</title> <link rel="stylesheet" type="text/css" href="extjs/resources/css/ext-all.css" /> <script type="text/javascript" src="extjs/adapter/ext/ext-base.js"></script> <script type="text/javascript" src="extjs/ext-all.js"></script> <script> Ext.onReady(function() { Ext.MessageBox.alert("hello","Hello,easyjf open source"); }); </script> </head> <body> </body> </html>
图1-11 hello.html页面效果
进一步,我们可以在页面上显示一个窗口,代码如下: Ext.onReady(function() { var win=new Ext.Window({title:"hello",width:300,height:200,html:'
Hello,easyjf open source
'}); win.show(); });
<script>
Ext.onReady(function()
{
var win=new Ext.Window({title:"hello",width:300,height:200,html:'<h1>Hello,easyjf open source</h1>'});
win.show();
});
</script>
在浏览hello.html,即可得在屏幕上显示一个窗口,如图xxx所示。
