Read json in javascript

Question

I have an array

 Array
(
 [1] => Array
 (
 [title] => Graslei BVBA
 [address] => Belgium Bent
 )
 [2] => Array
 (
 [title] => Red Poppy SPRL
 [address] => Belgium 4900 Spa
 )
 [3] => Array
 (
 [title] => Loula Bee
 [address] => Belgium Liege
 )
)

I pass array in javascript function as json_encode.

Please anybody can help me to read this JSON in javascript.

 var info = {
"1":{"title":"Graslei BVBA","address":"Belgium Bent"},
"2":{"title":"Red Poppy SPRL","address":"Belgium 4900 Spa"},
"3":{"title":"Loula Bee","address":"Belgium Liege"}
}

I want address from above to be read.

Thanks for help in advance.

• Mikael Härsjö: info.1.address? info.2.address?
• randomizer: What have you tried? Because you can just do something like mainelement.key.wantedelement ...
• Gary.S: doesn't work with numbers only as far as i can tell
• Gary.S: The JSON posted is not an array, it is just an object. A JSON array would be something like [{'title': 'some title'},{'title': 'another title'}]

Answer 1

One way to do this would be to use the index way of retrieving the value. Something like:

var info = {"1":{"title":"Graslei BVBA","address":"Belgium Bent"},"2":{"title":"Red Poppy SPRL","address":"Belgium 4900 Spa"},"3":{"title":"Loula Bee","address":"Belgium Liege"}};
$('P').append(info["1"].address);

You could even do this:

var addr = info["1"]["address"];

Answer 2

var info = {"1":{"title":"Graslei BVBA","address":"Belgium Bent"},"2":{"title":"Red Poppy SPRL","address":"Belgium 4900 Spa"},"3":{"title":"Loula Bee","address":"Belgium Liege"}};
/*
* info[number][string] 
*/
info[1] // Object {title: "Graslei BVBA", address: "Belgium Bent"}
info[1]["address"] // "Belgium Bent" 
// for 
for (var i in info) (function(title, address) {
 console.log(title, address); // print title and address
}(info[i]["title"], info[i]["address"]));

• Abhilasha: I have tried all the answers given here. But no success, when I alert(address); it shows undefined.

Answer 3

Most browsers support JSON.parse(), which is defined in ECMA-262 5th Edition (the specification that JS is based on). Its usage is simple:

var json = '{"result":xyz,"count":1}',
obj = JSON.parse(json);
 alert(obj.count);

For the browsers that don't you can implement it using json2.js.

Answer 4

Like the below:

info[1].address
info[2].address

But you may consider use an array instead of such object.

Answer 5

This should do the trick:

for(i in info){
 data=info[i];
 console.log("title: "+data.title+"\taddress: "+data.address);
}

Answer 6

var info = {
 "1":{"title":"Graslei BVBA","address":"Belgium Bent"},
			"2":{"title":"Red Poppy SPRL","address":"Belgium 4900 Spa"},
			"3":{"title":"Loula Bee","address":"Belgium Liege"}
		 }
					
for(var obj in info){	//repeats all the objects of "info"
 console.log("obj: "+obj);//prints "1","2","3" in the console
 for(var key in info[obj]){//repeats all the objects of "info[obj]" 
	 console.log("key: "+key);//key is "title","address" of info[obj]
	 console.log("value: "+info[obj][key]);//value "Graslei BVBA" for info["1"]["title"] and so on.
						
	}
					
}

output of the given code
