I have the following Json result:
(Taken from the console)
data
Object {0: Object, 1: Object, 2: Object, 3: Object, 4: Object, 5: Object, 7: Object}
if i in the console do data[0] i get the following result:
Object {id: 125, Module_id: 2, academy_id: 7, Team_id: 5, end: "2014-08-12 00:00:00"…}
However when i do data.length the value is undefined can anyone tell me what is going on?
Use Object.keys
Object.keys(data).length;
The Object.keys() method returns an array of a given object's own enumerable properties, in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).
You structured your json result as an Object not an Array. Do not mix those up! data[0] is the value of the first instance variable of the result object. If you want to structure your json object as an array before sending it to be parsed, then in your php file make sure you encode the object as an array
read.php
<?
$data = array('a' => 1, 'b' => 2, 'c' => 3);
print json_encode($data);
?>
data an array, as he's using it that way anyway.This will work as expected:
Object.getOwnPropertyNames(data).length
Object.keys(data).length
