Java 在jQuery完成后检索JSON对象

我正在尝试使用jQuery get检索JSON对象，我检索的对象希望嵌入到innerHTML中。下面的代码是如何构造JSON的

getListOfActivity.jsp

<%  
        String urusStr = request.getParameter("ukid");
        int urusId = Integer.parseInt(urusStr);

        lkpPdkCommon[] activity = getListOfActivity(urusId);
        if(activity!=null){
            out.println("{PartList:");
                out.println("[");
                    for(int x=0;x<2;x++){// the lkpPdkCommon[] return from getListOfActivity(urusId) huge so I limit the array to 2         
                        out.println("{");
                            out.println("ActivityID:\""+activity[x].getID()+"\",Description:\""+activity[x].getDescription()+"\"");
                        out.println("}");
                        if((x+1)!=2){
                            out.println(",");
                        }
                    }
                out.println("]");
            out.println("}");   

            response.setContentType("application/json");

    %>

下面的代码没有返回任何错误，但似乎不起作用。这是我使用firebug检查的JSON对象

您是否尝试过Jquery getJSON

我想这会对你有帮助

在我修改jsp中的以下行后，问题解决了

out.println("{PartList:");

到

及

到

在我进行修改之前，最初的JSON对象send by response标头如下所示：

{PartList:
        [
            {ActivityID:"8638",Description:"GERMS"},
            {ActivityID:"8639",Description:"GOVERNMENT CERTIFY PROGRAMMES"}
        ]
}

修改后呢?

{"PartList":
        [
             {"ActivityID":"8638","Description":"GERMS"},
             {"ActivityID":"8639","Description":"GOVERNMENT CERTIFY PROGRAMMES"}
        ]
}

    out.println("ActivityID:\""+activity[x].getID()+
"\",Description:\""+activity[x].getDescription()+"\"");

    out.println("\"ActivityID\":\""+activity[x].getID()+
"\",\"Description\":\""+activity[x].getDescription()+"\"");

{PartList:
        [
            {ActivityID:"8638",Description:"GERMS"},
            {ActivityID:"8639",Description:"GOVERNMENT CERTIFY PROGRAMMES"}
        ]
}

{"PartList":
        [
             {"ActivityID":"8638","Description":"GERMS"},
             {"ActivityID":"8639","Description":"GOVERNMENT CERTIFY PROGRAMMES"}
        ]
}
