Question

I am generating 2 json object by using the java script mentioned below.I am populating my json to the form fields, now the problem is I can display only one at a time, how to display the other json in a form at the same time?

//first json :

{"vIRnumber":"195412","dReceivedDate":"2012-06-06","vDescription":"GP Coils","fThickness":"888","fWidth":"4566","fQuantity":"122","vStatus":"work in progress"}

//second json:

{"vIRnumber":"45","dReceivedDate":"2012-04-26","dDate":"0000-00-00","dStartDate":null,"nPartyName":"Aasha","vDescription":"MS Channels","fThickness":"1.8","fWidth":"1220","fQuantity":"34523"} 

        //**i am filling the fields using the javascript below:**

        var json =<?php echo($data); ?>;
        for(key in json)
        {
          if(json.hasOwnProperty(key))
            $('input[name='+key+']').val(json[key]);
    }

For displaying the first json you could add the values next to the form item for example

<label for="form-item-staddress">St.Adress</label>
<input id="form-item-stadress" type="text" name="stadress"/>
<div class="default">Default value from first json</div> 

Load the first json in the div for displaying current value

For passing/saving the two json for submitting the form or processing other stuff you could try

<input type="hidden" id="firstJSON" value="FirstJSON"/>
<input type="hidden" id="seondJSON" value="SecondJSON"/>

or use 2 forms the first with the values of the first json, but can’t be edited/submitted only for viewing/reference and 2nd form for editing/submitting.
