Loop and get key/value pair for JSON array using jQuery

Question

I\'m looking to loop through a JSON array and display the key and value.

It should be a simplified version of the following post, but I don\'t seem to have the syn

Answer 1

var obj = $.parseJSON(result);
for (var prop in obj) {
    alert(prop + " is " + obj[prop]);
}

Answer 2

Parse the JSON string and you can loop through the keys.

var resultJSON = '{"FirstName":"John","LastName":"Doe","Email":"johndoe@johndoe.com","Phone":"123 dead drive"}';
var data = JSON.parse(resultJSON);

for (var key in data)
{
    //console.log(key + ' : ' + data[key]);
    alert(key + ' --> ' + data[key]);
}

Answer 3

You can get the values directly in case of one array like this:

var resultJSON = '{"FirstName":"John","LastName":"Doe","Email":"johndoe@johndoe.com","Phone":"123 dead drive"}';
var result = $.parseJSON(resultJSON);
result['FirstName']; // return 'John'
result['LastName'];  // return ''Doe'
result['Email']; // return 'johndoe@johndoe.com'
result['Phone'];  // return '123'

Answer 4

The following should work for a JSON returned string. It will also work for an associative array of data.

for (var key in data)
     alert(key + ' is ' + data[key]);

Answer 5

You have a string representing a JSON serialized JavaScript object. You need to deserialize it back to a JavaScript object before being able to loop through its properties. Otherwise you will be looping through each individual character of this string.

var resultJSON = '{"FirstName":"John","LastName":"Doe","Email":"johndoe@johndoe.com","Phone":"123 dead drive"}';
var result = $.parseJSON(resultJSON);
$.each(result, function(k, v) {
    //display the key and value pair
    alert(k + ' is ' + v);
});

The best and perfect solution for this issue:

I tried the jQuery with the Ajax success responses, but it doesn't work so I invented my own and finally it works!
