Json Parsing in ajax

if you send data as json on server you can use responce.data but you can dumps json object and send it as string, and use var r = JSON.parse(responce)

I will try to explain the actual situation :

Assume you have array of objects :

var g = [{a:1,b:2},{c:1,d:2}];

Let's convert it to json string :

var json = JSON.stringify(g); //"[{"a":1,"b":2},{"c":1,"d":2}]"

Now , this is your situation :

the server returns :

"[{"a":1,"b":2},{"c":1,"d":2}]"

How can you parse it ?

var parsed = JSON.parse(json);

Great. now let's look how the browser sees it :

enter image description here

so how would you access the first item ?

Right , via [0] like dystroy write in his comment.

you can try like this

$(document).ready(function() 
 {
 ($.ajax({ 
 url:"allServices/getBusinessDetails.php?busid=<? echo $business_id; ?>",
 dataType: "json",
 success: function (jsondata) {
 var allval=JSON.stringify(jsondata); 
 console.log(allval[0].address);
 }
 })); 
});

I'm not sure but i think its helpful to you.

Just use jQuery.parseJSON

like this var obj = jQuery.parseJSON( '{ "name": "John" }' );

see https://api.jquery.com/jquery.parsejson/

If you get undefined the data you are trying to parse is probebly unvalid. You can try if its valid here http://pro.jsonlint.com

$(document).ready(function(){
$.getJSON("allServices/getBusinessDetails.php?busid=<? echo $business_id; ?>",function(data){
 $.each(data,function(key,value){
 alert(data[key].attrib1name);
 alert(data[key].attrib2name); 
 console.log(value);
 });
 }); 
});

Or this approach

 $(document).ready(function(){
 $.getJSON("allServices/getBusinessDetails.php?busid=<? echo $business_id; ?>",function(data){
 parseJsonArray(data);
 });
function parseJsonArray(obj) {
 // Do something.
 $.each(obj, function (idx, obj1) {
 if (typeof obj1 == 'object') {
 parseJsonArray(obj1);
 } else {
 alert(idx+":"+obj1);
 }
 });
}
