PHP Array as JavaScript - accessing the JavaScript elements by key?

I have a PHP array, like that:

$myArray = array('key1' => value1, 'key2' => value2);

I am converting it to JSON using this code:

$js = json_encode($myArray);

Now in my JavaScript code I want to access the JS array (object?) by its keys, key1 for example, but it doesnt work, the result is always undefined.

Thanks!

First, you parse the JSON. There are different options to do that, but for example: 

var parsedData = JSON.parse(your_data);

And then you access to the key you're looking for. The following is an "associative" way to access to an array (check this out).

alert (parsedData.your_key);

Good luck!

Try this code

function parseJSON(jsonString){
  return eval("(" + jsonString + ")");
}

var object = parseJson(StringFromPhp);

You can get mykey like:

object.key1  // value1

Try this

var json = 'yourjsonstring',//'{"key1":"value1","key2":"value2"}'
var obj = JSON.parse(json);
alert(obj.key1);
