………………(页面其它内容)
<script type="text/javascript">
Ext.get('loading').remove();
function showAbout(){
Ext.Msg.alert("关于","<div><img src='../images/about.jpg'/></div><div style='float:left;width:400px;'><hr/><h2>开发者:凌艺宾<br/>学校:中南大学<br/>培训:蓝杰公司<h2></div>");
}
</script>
</body>
</html>
或者做得简单一点:
直接在button里面加上如下语句就行了
handler : function() { if (loginPanel.form.isValid()) { loginPanel.form.submit( { url : 'login.do', success : function(from, action) { Ext.get('loginpanel').remove(); window.location.href='pages_share/main.html'; }, failure : function(form, action) { Ext.MessageBox.show({ title:"登录失败", msg:"登录失败!请认真检查您的姓名密码及身份。", icon:Ext.MessageBox.ERROR, buttons:{"ok":"确定"} }); }, waitMsg : '正在登录,请耐心等候...' });
