    String[] a = ids;
    // Do whatever processing you want
    // However, you cannot access server controls

    Either you can send Plain text or JSON. But there is an issue in your code. You are sending the content type "application/json", but you are sending the invalid JSON input. {"1,","2","3"} is not a valid JSON string . { "ids": "1,2,3" } is the valid JSON. You can validate the json in "". In the web method you an receive the Sting and convert it into the array.

    I think JSON is the good way
    see below snippet

    var array = [ 'item1', 'item2', 'item3' ];
    url: '/foo.aspx/SaveView',
    type: 'POST',
    contentType: 'application/json',
    data: JSON.stringify({ myArray: array }),
    success: function(result) {

    If your Page Method returns something, you should use the result.d property in the success callback to fetch the result of the page method call.
    hope it helps
