Question

我正在尝试从js和html访问Spring Model属性。我已经按照下面的链接尝试了所说的一切，但我一直收到错误：
How to access model attribute in Javascript

这是我的代码：

     MyVOClass.java  

     private String id; 
     private String name; 
     //getters setters here 

     MyController.java 
     @RequestMapping(value = "/Display", method = RequestMethod.GET, headers 
      = "Accept=text/html")
      public String Display(@RequestParam(value = "id", required = true) 
      String id, @RequestParam(value = "name", required = true) String name, 
       Model model) {

      //set the values to the VO Object 
      MyVOClass myVo = call to another class to set the values 
      model.addAttribute("myVo ", new Gson().toJson(myVo));

      return "html page name "; 


      Js file: 
      var ID = JSON.parse('${myVo.id}');

我在控制台上收到以下错误：

     angular.js:14525 SyntaxError: Unexpected token $ in JSON at position 0
     at JSON.parse (<anonymous>)

编辑2：

如果我尝试

      var ID = JSON.parse(${myVo.id});

我收到以下错误：

      Uncaught SyntaxError: missing ) after argument list
      Uncaught Error: [$injector:modulerr]

我不确定我错过了什么？我需要在我的js和html中使用任何其他配置来访问Model吗？

编辑1：

添加我的Java API代码：

     @RequestMapping(value = "/display", method = RequestMethod.GET, headers 
     = "Accept=text/html")
     public String display(@RequestParam(value = "param1", required = true) 
     String param1, Model model) {

    String html = "/view";
    MyVo myVo = new MyVo();
    //set data 

    Gson gson = new Gson();
    String respJson = gson.toJson(authresp);

    String respstr = authrespJson.toString();
    model.addAttribute("myVo ", respstr );
    System.out.println("response Json string "+respstr );

    return html;
    }

无法在javascript中访问Spring模型属性
