passing json array ajax

Question

Trying to pass a array using ajax call.

info = [];
info[0] = 'hi';
info[1] = 'hello';

$.ajax({
    type: "POST",
    data: {info: info, "action": "getPatientRecords"},
    url: "/mobiledoc/jsp/ccmr/webPortal/carePlanning/servicePatientmilestoneModal.jsp",
    success: function(msg) {
        $('.answer').html(msg);
    }
});

However when i try to catch it on the server side using : request.getParameter("info"); //Displays null**

Also, if i wish to send an array of arrays ? is it possible?

I tried using serialize however my IE throws error that serialize : object doesnt support this property i Did include jquery lib.

Answer 1

You can use JSON.stringify(info) to create a JSON representation of the object/array (including an array of arrays). On the server side you should be able to get the string via getParameter and then unserialize it from JSON to create constructs JSP can use.

Answer 2

Yes,It is Possible to send arrays.

var info_to_send = ['hi','hello'];

$.ajax({
    type: "POST",
    data: {info: info_to_send, "action": "getPatientRecords"},
    url: "/mobiledoc/jsp/ccmr/webPortal/carePlanning/servicePatientmilestoneModal.jsp",
    success: function(msg) {
        $('.answer').html(msg);
    }
});
