我提出我的Ext JS的形式后得到以下错误:未捕获Ext.Error:你试图解码无效的JSON字符串:表单提交使用的Ext JS和Spring MVC
Uncaught Ext.Error: You're trying to decode an invalid JSON String
JS:
Ext.onReady(function() {
var simple = Ext.create('Ext.form.Panel', {
frame : true,
title : 'Login Form',
bodyStyle : 'padding:5px 5px 0',
width : 350,
fieldDefaults : {
msgTarget : 'side',
labelWidth : 75
},
defaultType : 'textfield',
defaults : {
anchor : '100%'
},
items : [{
fieldLabel : 'User Name',
name : 'userName',
allowBlank : false,
emptyText : 'UserName'
}, {
fieldLabel : 'Password',
name : 'password',
allowBlank : false,
inputType : 'password',
emptyText : 'Password'
}],
buttons : [{
text : 'Save',
handler : function() {
var form = this.up('form').getForm();
form.submit({
url : saveFormUrl
// waitMsg : 'Sending the info...',
// success : function(fp, o) {
// Ext.Msg.alert('Success',
// 'Form submitted.');
// }
});
}
}, {
text : 'Cancel'
}]
});
simple.render(document.body);
simple.getEl().center();
});
Controller类:
@Controller
public class UserController {
private static final Logger logger = LoggerFactory
.getLogger(TController.class);
private TService tService = null;
@Autowired
public void setTService(TService tService) {
this.tService = tService;
}
@RequestMapping(value = "/index.html", method = RequestMethod.GET)
public String home() {
System.out.println("Welcome home!");
return "login";
}
@RequestMapping(value = "/save-form.html", method = RequestMethod.POST)
public ModelAndView submitData(User user){
System.out.println("User name:"+user.getUserName());
ModelAndView mv = new ModelAndView("htmlLinks");
return mv;
}
保存-form.html:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page session="false"%>
<c:set var="ctx" value="${pageContext.request.contextPath}" />
<html>
<head>
<title>POC</title>
</head>
<body>
Welcome User !!
</body>
</html>
我在做什么错?解决办法是什么?我正在使用Ext JS 4和Spring MVC。
你已经采取了看看这个:http://stackoverflow.com/questions/7023531/extjs-4-spring-3-file-upload-server-sends-bad-response-content-type – andy 2012-07-24 17:05:24
我曾看过它,但我的问题是,我从Spring控制器类返回时解析另一个jsp。所以,我不确定,我该怎么做? – 2012-07-24 18:28:48
我没有extJS的经验,但抛出异常在哪里(是否在JS中注释掉的行中)?另外,你打算如何使用HTML响应? – andy 2012-07-24 21:18:08
