• javascript
• jquery
• facebook
• string
• split

• 6 Most probably this is because friendId is not a string but an array. – VisioN Commented May 14, 2012 at 12:12
• 7 What does console.dir(friendId) or console.log(typeof friendId) tell you? alert is the worse debugging method you could have possible chosen. – Felix Kling Commented May 14, 2012 at 12:14
• 2 console.log(typeof(friendId)) returns object – Code Prank Commented May 14, 2012 at 12:23
• 1 Then you should address a certain property or iterate it to get the values. – VisioN Commented May 14, 2012 at 12:24
• how can i iterate through in objects like we use forin loop for arrays is there any equivalent for objects? – Code Prank Commented May 14, 2012 at 12:30

Most probably friendID is already an array. If you call alert the array is converted to a string and bees a ma separated list of values.

Note that converting an array to a string is not the same as calling JSON.stringify (where you get also brackets and double quotes around elements when they're strings)

The JavaScript split() function is for the type string ie for eg.

var friendid='1,34,67';

As VisioN says, when you alert an array you get ma separated values.

You can traverse JS Objects like this

for (var key in friendid) {
   var obj = friendid[key];
   for (var prop in obj) {
      alert(prop + " = " + obj[prop]);
   }
}

Hope this helps

alternate

for( var x in friendId )
 {
  alert(friendId[x]); // this would be your desired value
 }
