How do you send an array as part of an (jquery) ajax request

Question

I tried to send an array as part of an ajax request like this:

var query = [];
// in between I add some values to \'query\'
$.ajax({
    url: \"MyServlet\",

You have to send an object which you first stringify with JSON.stringify.

like this:

var query = [];
// in between I add some values to 'query'
$.ajax({
    url: "MyServlet",
    data: JSON.stringify({ nameParameter: query })
    dataType: "json",
    success: function(noOfResults) {
        alert(noOfResults);
    }
  });
}
