php array to javascript array (called from a function)

I have an array in php file test.php; I need it in Javascript array.

<?php 
$phpArray = glob('*.jpg');
echo json_encode($phpArray);
?>

I need each filename in Javascript array so I can access it like:

myJavasciptArray[0];

I need to get my JavaScript array loaded from the function:

$("#button2").click(function(){
$.get("test.php",function(data){
var mypics=data;
  alert(mypics[1]);      
});
});

but what I get instead of each filename in the array is a character.

myJavasciptArray[0]="["

instead of:

myJavasciptArray[0]="myfile1.jpg"

What you getting is a string back from the request, you will need to use JSON.parse() function to get the correct json object

var mypics = JSON.parse(data)

instead of using jQuery.get(), use jQuery.getJson() and you should be fine. If you don't, myJavascriptArray is a string, and someString[0] means the first letter of the string.

Try JSON.parse here :

$.get("test.php",function(data){
    var mypics = JSON.parse(data);
    alert(mypics[1]);      
});

You are not getting result as JSON type.

Add json dataType to your $.get() so result is parsed as JSON:

$("#button2").click(function(){
   $.get("test.php",function(data){
      var mypics=data;
      alert(mypics[1]);      
   }, 'json');
});
