表单提交方式一

   ,buttons:[{
			text : '登录'
			,handler : login
		}, {
			text : '取消'
			,handler : function() {
				FormPanel.loginForm.getForm().reset();
			}
		}]

 

 

function login(){
	if(!FormPanel.loginForm.getForm().isValid()) return;
	FormPanel.loginForm.getForm().submit({
		waitMsg: '正在提交数据...',
		waitTitle: '提示',
		url: '../../AdminServlet?method=checkUser',
		method: 'POST',
		success: function(form,action){
			
			Ext.MessageBox.alert("提示",action.result.errors.info);		
		},
		failure: function(form,action){
			Ext.MessageBox.alert("提示",'原因如下:'+action.result.errors.info)
		}
	});
}
new Ext.KeyMap(document,{
	key: Ext.EventObject.ENTER,
	fn: login,
	scope: this
})

 

 

服务器端代码：

String username = request.getParameter("username");
String password = request.getParameter("password");
String authcode = request.getParameter("authcode");
System.out.println(username+password+authcode);
out.write "{ success: true, errors:{info:'okay'} }";

 

如果返回错误信息则:

out.write "{ success: false, errors:{info:'okay'} }";
