Passing A Php Array To Javascript?

[Solarpitch]

Hey Guys,

 

Just trying to pass a php array to a Javascript function but I keep getting undefined. I'm sure my syntax is slightly incorrect.

 

PHP

 

...
$arr = array();
$arr[0] = $this->load->view('video',);
$arr[1] = "A String";

return json_encode($arr); // this returns to the below Javascript $.POST responce.

 

Javascript

 

...
$.post('http://mysite.com//api/ajaxApiCall', 'val=' + val, function (response) {

alert(response[0]);
alert(response[1]);

});

You need to JSON.parse the array coming back. It reads in from the AJAX call a string, so it doesn't know that it is actually supposed to be an array.

When I try do that:

 

obj = JSON.parse(response);
alert(obj.count);

 

I just get this error. Dunno why :-\

 

SyntaxError: JSON.parse: unexpected end of data

obj = JSON.parse(response);

It actually works when I replace the return with echo.

Funny that.
