We can use the angular.element(document).ready() method to attach callbacks for when the document is ready. We can simply attach the callback in the controller like so:
***
angular.module('MyApp', [])

.controller('MyCtrl', [function() {
angular.element(document).ready(function () {
document.getElementById('msg').innerHTML = 'Hello';
});
}]);

I've had to implement pagination quite a few times with Angular, and it was always a bit of a pain for something that I felt could be simplified. I've used some of the ideas presented here and elsewhere to make a pagination module that makes pagination as simple as:
***

• {{ item }}

// then somewhere else on the page ....


***
That's it. It has the following features:

No custom code needed in your controller to tie the collection items to the pagination links.
You aren't bound to using a table or gridview - you can paginate anything you can ng-repeat!
Delegates to ng-repeat, so you can use any expression that could be validly used in an ng-repeat, including filtering, ordering etc.
Works across controllers - the pagination-controls directive does not need to know anything about the context in which the paginate directive is called.

There is no shortcut for converting from int[] to List as Arrays.asList does not deal with boxing and will just create a List which is not what you want. You have to make a utility method.
***
int[] ints = {1, 2, 3};
List intList = new ArrayList(ints.length);
for (int i : ints)
{
intList.add(i);
}

A query string carries textual data so there is no option but to explode the array, encode it correctly and pass it in a representational format of your choice:
***
p1=value1&pN=valueN...
data=[value1,...,valueN]
data={p1:value1,...,pN:valueN}
***

and then decode it in your server side code.
