parse json string

Question

I have the following Json string

{ \"Users\" : [ 
    { \"Name\" : \"user99\",
      \"Value\" : \"test\"
    },
    { \"Name\" : \"test2\",
      \"Value\"          


        

Answer 1

You actually have an array of objects so..

var obj = $.parseJSON(string);

var users = obj.users;    

for x in users {
    alert(users[x].Name);
    alert(users[x].Value);
}

Answer 2

<script>
var str = '{"Users":[{"Name":"user999","Value":"test"},{"Name":"test2","Value":"test"}]}';
str = eval('('+str+')');
alert(str.Users[0].Name);

//var str = '{"x":{"a":"1"}}';
//alert(str.x.a);
</script>

Answer 3

You can use jQuery.parseJSON, here's an example:

var jsonString = '{"key":"value","otherkey":"othervalue"}';
data = $.parseJSON(jsonString);
alert(data.key); // Shows: value

Answer 4

For the JSON you have given, $.parseJSON should return an object, myObj, that can be accessed like so:

var users = myObj.Users,
    user0_name = users[0].Name;

Answer 5

var json = '{"Users":[{"Name":"user999","Value":"test"},{"Name":"test2","Value":"test"}]}';

var json_parsed = $.parseJSON(json);

for (var u = 0; u < json_parsed.Users.length; u++){
    var user = json_parsed.Users[u];
    $('body').append($('<p>').html('User: '+user.Name+'<br />Value: '+user.Value));
}

Results in:

<p>User: user999<br />Value: test</p>
<p>User: test2<br />Value: test</p>
