How to print java Map name/value pair through JSON object in JS

[Kuts Aryan]

Hi
I am using struts2 framework and from my js file I am invoking my action class through AJAX call.In the success part of ajax I am getting a JSON object of java map like below

   <action name="findDeviceModelActionJSON" class="findDeviceModelJSON" method="findDeviceModel">
            <result type="json">
                <param name="root">typeModel</param>
            </result>
        </action> 

where typeModel is a object of DeviceTypeModel class and DeviceTypeModel class is having a java Map <String,String> class variable.
My question is in the java script part after getting the json object, how can I access this map key/value pair using JSON so that in the jsp page I can print the name/value pair
for the whole map object.

Please help me...............

Are you asking how to create DOM elements for each key/value pair in the JavaScript object? Which part of that specifically given you a problem, iterating over an object's properties, or creating the DOM elements?

Please don't post the Struts-specific part in the HTML/JS forum--it's completely irrelevant to what you're trying to do. How the JSON is retrieved is totally irrelevant--you're basically asking how to iterate this:

var foo = { "wat": "Ohai", "baz": "plugh" };

Right?

thanks for your reply and you are correct.I want to know about the iteration of JSON object.Right now I am doing the iteration like below

   
for (var p in foo) {
            alert(p + ':' + foo[p]);           
 }
 

It is working but the order of displaying the element is not proper.If my JSON object contains

var foo = { "A":"a","B":"b","C":"c","D":"d"};
It is sometimes printing the oder like
D:d
A:a
B:b
C:c
like this.......Is there any way to display the order properly ?

Object properties are not ordered. So there is no such thing as "proper order".

If you want ordered, use an array.
