How can I print the length of this JSON Object?

 

This question already has an answer here:

  • Length of a JavaScript object 32 answers

    • Arrays have a length property. Objects do not (by default). I think the problem is on the php end ... You should be encoding an array and sending that back instead. Arrays are zero-indexed, so that may be the problem. Perhaps json_encode(array_values($msg)) .

    If your keys are correct after all, give Object.keys(msg).length a shot.

    This can be a duplicate of Length of a JavaScript object

    Look at the accepted answer.

    BTW, just found googling "javascript object length" ;)

    EDIT:

    It's true that objects don't have a length property, and you can get the length with Object.keys(foobar).length, but it won't work in IE8 (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys)
