Ext中FormPanel面板及Form控件横排测试(CSS)

在实际的网页开发中，大部分时间都要涉及到Form表单的处理。在Ext框架中也提供了很多这方面的控件，而且还有一个专门的FormPanel布局，该布局默认为放在面板上面的所有控件都是换行放置，而在实际应用中为了美观，有些需要横排，特别是Radio控件，这个时候就需要我们重新定制这些控件的布局了，该例子中使用CSS来实现这些功能，先贴出一张效果图。

//确定按钮事件,这里只是简单获取各控件值,实际应用一般和后台脚本结合
function onOK() {
var strMsg;
strMsg = ‘姓名：’ + fp.getComponent(’i_username’).getValue() + ‘，性别：’;

//创建主窗口 new Ext.Window({ title:’Ext中FormPanel面板及Form控件横排测试(CSS)’, 400, closable:false, collapsible:true, draggable:false, resizable:false, modal:true, border:false, items:[fp], buttons:[] }).show(); }); </script> </body> </html>
