Convert json to array in jquery

Question

I'm trying to convert my json object into array. I've saw many questions on SO but that didn't help me.

My PHP Code :

$arr = Array ( [1] => 10 [5] => 20 ) //array key is random

I want to assign above array to jQuery variable.

Jquery Code :

var obj = '<?php echo json_encode($arr)?>';

when i print obj it gives me {"1":"10","5":"20"}. i want result in array like [1:10,5:20].

And after that i want to access array values by its key (e.g. obj[1] or obj[5])

Ignore my syntax error.

Thanks.

var encodedJson = '<?php echo json_encode($arr)?>'; var obj = $.parseJSON(encodedJson); alert(obj[1]); // this will show as 10 — Alankar More

@Vaira : Mr. Engineer wants to assign the php array to javascript variable. json_decode will convert the json data to php array. Not php array to json. — Alankar More

You just need to define var obj without usage of ' in script

<script>

var obj = <?php echo json_encode($arr)?>;
alert(obj[1]);// will alert 10

</script>

 var data; //suppose data contains the json result i.e {"orders":[{"name":"Accessories"}}]
 var response_length=response.orders.length; //orders is the json array
  var array_store = [];
 for (i = 0; i < response_length; i++)
   array_store .push(response.orders[i].name); //name is json object

Simple Solution is as below:

var encodedJson = '<?php echo json_encode($arr)?>'; 
var obj = $.parseJSON(encodedJson); 
alert(obj[1]); // this will show as 10
