JQuery: json array problem during web service development

hello all,

i use a php client to read soap response message from a web service. The value i read will be transmit to javascript by using json.

the problem i met is:
let's say i got two variable from web service, and i would like to display them line by line.

 in firebugs the JSON looks like:

var01:
[Object{information="first one"}, Object{information="second one"}]

var02:
Object{information="third one"}

you see the different, var02 just have one Object, and he doesn't contain symbol [ ].

for var01, i can use following codes to display it on the screen:

$.each(var01, function(index, details){                                                    
     $.each(details, function(subindex, val) {                                
                   $("#divId").append(val);
                   $("#divId").append('</br>');
      });                            
 });

but for var02, if i use the codes above,  i got a wrong result, the output is "third one" but "t" "h" "i" "r" "d" " " "o" "n" "e"

the question is:
1: how do i show var02 correctly, the output excepte is "third one".
2: because in my project, the var01, var02 are depended on web service, i don't know when they will contain symbol [ ], when not.  Are there anyway to detect that
Object{information="third one"}
is not
[Object{information="third one"}] ?
3: How do i convert
Object{information="third one"}
to
[Object{information="third one"}] ?

thanks,
