How do I get the length of a JSON file?

First, you’ll have to create a properly formatted JSON file. Once you’re done with that, getting the current number of objects from that list is a piece of cake.

<script>
$.getJSON('json/myjsonfile.json',function(data){
var json = data;
alert(json.length);
});
</script>

Pull in the feed via getJSON function, toss it into a variable (I called mine json) and grab the length with .length. My example alerts the number of entries but you can do what ever you’d like.
