I need reload the content of a div with a part of an object JSON. The code below does it perfectly, but the resulting div get all the JSON object and between {}. I need the content to appear only one variable.

JSP:

<s:url id="ajax1" value="ajax1.action"/>
<sj:div id="div1" 
    href="%{ajax1}" 
    reloadTopics="reloaddiv1">
</sj:div>
<sj:a 
    id="refreshlink" 
    onClickTopics="refreshdiv" 
    button="true">Refresh Div
</sj:a>

JavaScript:

    <script type="text/javascript">
        $.subscribe('refreshdiv', function(event,data) {
            $.publish('reloaddiv1');
        });
    </script>

My action:

<package name="default" extends="struts-default,json-default" namespace="/">
    <result-types>
        <result-type name="json" class="org.apache.struts2.json.JSONResult" />
    </result-types>

    <action name="ajax1" class="action.Div">
        <result type="json"/>
    </action>

</package>

MY CLASS action.Div

String hi = "hi world";
String bye = "bye world";

@Override
public String execute() throws Exception {
    return SUCCESS;
} 

/* getters and setters*/

Output shown in my div:

{"bye":"bye world","hi":"hi world"}

How do I make you see just "hi world"?

  • Struts2 JSON Plugin serializes the entire Action, so if you need only one variable, you need to specify a root object ("hi", in your case) in struts.xml.

  • You will then get "hi world". If you want the value without the double quotes, you need to instruct JQuery plugin to make it aware that it's dealing with JSON Data; add dataType = "json" to your <sj:div> as described here, and you will get hi world.

  • I did not understand, that means I should ask another question in another post? or the same? – Ivan Jan 15 '14 at 15:42
  • Ask another question expanding what you was saying in the comment. This is a legit question, and already has a correct answer; changing the question after it was answered won't help future visitors. – Andrea Ligios Jan 15 '14 at 15:44
