Question

我正在尝试将Json作为回调参数传递。任何人都可以更正javascript以获取json对象的值吗？

的javascript

function renderTopic(xhr,status,args){
        alert("iam In renderTopic");
        var topicObject = $.parseJSON(args.topicJSON);
        for(var x in topicObject){
            alert(x.topicBody);
        };
    }

服务器端

   jGenerator.writeFieldName("topicBody");
            jGenerator.writeStartArray();
                 ...............
            jGenerator.close();
             context = RequestContext.getCurrentInstance();
             System.out.println("JSON output in string "+out.toString())

XHTML

<p:commandLink action="#{topicController.listAllTopics}"
                id="topicListAllCmdLink" value="" oncomplete="javascript:renderTopic(xhr, status,args)"/>

http响应

<partial-response><changes><update id="javax.faces.ViewState"><![CDATA[4091946826703479326:-2361306414195161728]]></update><extension ln="primefaces" type="args">{"topicJSON":"{\"topicBody\":[\"Test10\",\"Test22\",\"Test4\",\"Test11\"]}"}</extension></changes></partial-response>

每件事似乎都没问题。你看到有什么错误吗？或者您可以告诉我们的任何输出。
