passing array to servlet via ajax gives null parameter

Question

new to ajax and not quite sure whats wrong. I have:

var myArray = [2324.031536  ,
               2355.015241  ,
               2397.099387  ,
               2444.286019];

$(document).ready(function() {                        
        $('#submit').click(function(event) {
            $.get('VsPredictionServlet',{myArray:myArray},function(responseText) { 
                $('#text').text(responseText);
            });
        });
    });

and in servlet:

String[] myArray = request.getParameterValues("myArray");

but myArray is null in servlet.
Any suggestions?

just do this:

$.get('VsPredictionServlet',{ "myArray": myArray},function(responseText) {
            $('#text').text(responseText);
});

you need to pass parameter as a string.

use JSON.stringify data = JSON.stringify({ "myArray" = myArray }); $.get('VsPredictionServlet', data ,function(responseText) { $('#text').text(responseText); });
