Question

我正在尝试简单的把手。最初我尝试使用静态Javascript数组对象来处理车把数据，它运行正常。所以我尝试使用Javascript Array对象作为来自Java RestURL的JSON字符串（以使把手数据动态化）并编译把手。我通过AJAX调用从RestURL获取数据，甚至模板也是从把手构建的。真正的问题是调用模板函数时，它不会生成带模板的响应数据。以下是HTML代码：

＆＃13;

<html>
<head>
<title>Handlebars.js Demo</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"> </script>
<script src="js/handlebars.js"> </script>
<script id="some-template" type="text/x-handlebars-template">
<table>
<thead>
<th>id</th>
<th>username</th>
<th>password</th>      
</thead>
<tbody>
{{#Users}}
<tr>
<td>{{id}}</td>
<td>{{username}}</td>
<td>{{password}}</td>          
</tr>
{{/Users}}
</tbody>
</table>
</script>
</head>
<body>
<div id="content"></div>
<script>
$(document).ready(function()
{
$.ajax({
url:"http://localhost:8082/Backbone/rest/test/test1",
method:'get',
success:function (results) 
{
var source   = $("#some-template").html();
var template = Handlebars.compile(source);
$("#content").html(template(result));
}
})  	
});
</script>
</html>

＆＃13;

java Rest代码：

@Path("/test")
public class Common
{
@GET
@Path("/test1")
public Response getMsg() 
{
Users user=new Users(1,"harish","ram");
String output=toJson(user);
return Response.status(200).entity(output).build();
}
public String toJson(Object object)
{
Gson gson=new Gson();
String str=gson.toJson(object);
return str;
}
}

用户类：

public class Users 
{
   private int id;
   private String username;
   private String password;
   public Users(int id,String username, String password){
     this.id=id;
     this.username = username;
     this.password = password;
   }
   public int getId() {
    return id;
   }
   public void setId(int id){
    this.id = id;
   }
   public String getUsername(){
    return username;
   }
   public void setUsername(String username){
    this.username = username;
   }
   public String getPassword(){
    return password;
   }
   public void setPassword(String password){
    this.password = password;
   }   
}

请帮我解决这个问题。

我通过更改RestURL解决了这个问题，如下所示

@GET
@Path("/test1")
@Produces(MediaType.APPLICATION_JSON)
public JSONObject getMsg() throws JSONException 
{
    String output ="{ users:  [{username: \"alan\", firstName: \"Alan\", lastName: \"Johnson\", email: \"alan@test.com\" },{username: \"allison\", firstName: \"Allison\", lastName: \"House\", email: \"allison@test.com\" },{username: \"ryan\", firstName: \"Ryan\", lastName: \"Carson\", email: \"ryan@test.com\" }]};";
    JSONObject obj = new JSONObject();
    obj.put("id", 3);
    obj.put("userName", 1);
    obj.put("password", 2);
    return obj;        
}

Handlebars.js无法使用AJAX JSON响应
