未捕获的错误：您正在尝试解码无效的JSON字符串

Question

我遇到了使用Java存储数据的EXT js代码的问题。下面是我的代码。有谁能帮帮我吗。

下面是我的NewCustomersVerify.js代码：

var myHit = Ext.create('Ext.data.Store',{
    fields:['Id','Name'],
    data:[
        {Id:'0',Name:'No'},
        {Id:'1',Name:'Yes'}
    ]
});
var myRisk = Ext.create('Ext.data.Store',{
    fields:['Id','Name'],
    data:[
        {Id:'0',Name:'Low'},
        {Id:'1',Name:'High'}
    ]
});

Ext.define('Test.test.web.test.view.test.NewCustomersVerify', {
     "xtype": "newCustomersVerify",
     "items": [{
          "xtype": "panel",

下面是我在浏览器控制台上遇到的错误。

[E]ext.JSON.decode（）：您正在尝试解码无效的JSON字符串：Apache Tomcat/8.0.21-Error reportH1{font-family：Tahoma,Arial,sans-serif；color：white；background-color:#525d76；font-size:22px；}H2{font-family：Tahoma,Arial,Sans-serif；color：white；background-color：#525d76；font-size：16px；}H3{font-family：Tahoma,Arial,Sans-serif；color：white；background-color：#525d76；font-size：14px；}正文{font-family：Tahoma,Arial,Sans-serif；color：black；background-color：white；}B{font-family：Tahoma,Arial,Sans-serif；color：white；background-color：#525d76；}P{font-family：Tahoma,Arial,Sans-serif；background：white；color：black；font-size：12px；}A{color：black；}A.name{color：black；}.line{height:1px；background-color:#525d76；border：none；}

Ajax成功或失败函数出错。您正在尝试解码从控制器（或中间层服务器）传递的无效json。您需要在解码任何字符串之前控制台响应。只需在ext.decode（）之前添加控制台日志。并在此发布响应。那会解决你的问题。
