How to pass an array as a URL parameter?

Question

I would like to pass an array and added to a link on my page as a URL parameter, because later on the server side I need the values from the array. How should I do that?

Answer 1

You can serialize the JSON:

myArray = ['aaa', 'bbb', 'ccc'];
var arrStr = encodeURIComponent(JSON.stringify(myArray));
$('#myLink').attr({ href: '/myLink?array=' + arrStr });

If your parsing (on the next page) is done via JavaScript too, you'll conversely use JSON.parse(). In PHP it would be json_decode().
