Send array via GET request with AngularJS' $http service

You can also just do

$http(
  method: 'GET',
  url: '/items',
  params: {
    "id[]": ids // ids is [1, 2, 3, 4]
  }
)

as mentioned here. Seems simpler.

$http(
  method: 'GET',
  url: '/items',
  params: {
    id: JSON.stringify(ids) // ids is [1, 2, 3, 4]
  }
)

jQuery is great but if your adding jQuery just for this then you could probably do with a non jQuery way and save some precious bytes.

Non jQuery way :

$http(
  method: 'GET',
  url: '/items',
  params: {
    id: ids.toString() //convert array into comma separated values
  }
)

On your server convert it back to an array.

Eg. in php

$ids = explode(',',Input::get('ids'));

//now you can loop through the data like you would through a regular array. 

foreach($ids as $id)
{
 //do something
}

This is valid, just decode it on your backend. Almost all backend languages have a way to decode a URI. If you don't like the way that Angular is serializing it, you can try jquery's $.param().
