How to pass array of values from multiselect into jquery ajax call?

Question

I'm using jQuery multiSelect and want to pass the selections to my update script.

Here's my ajax call

var newnotesecurity = $("#nt_newnotesecurity").serializeArray();

$.ajax({
  url: 'notes-savenewnote.php',
  method: 'POST',
  data: {
    cache: false,
    companyid: companyid,
    entitytype: entitytype,
    entityid: entityid,
    noteinitials: newnoteinitials,
    notetext: newnotetext,
    notetags: newnotetags,
    notesecurity: newnotesecurity
  },
  success: function() {
    // blah
  },
  error: function(){
    // blah
  }
});

nt_newnotesecurity is the multiselect object. Obviously serializeArray is not working for me. It's just my latest attempt to get this working.

I end up passing in this:

notesecurity[0][name]=nt_newnotesecurity&
notesecurity[0][value]=2&
notesecurity[1][name]=nt_newnotesecurity&
notesecurity[1][value]=14

but I'd like to pass in this

nt_newnotesecurity=2&nt_newnotesecurity=14

or I'd be just as content to pass in a single value that I can explode later on, like this

notesecurity=2-14

According to the documentation for the multiselect plugin, just calling val() should get you all the values

var newnotesecurity = $("#nt_newnotesecurity").val();

Thank you. That works perfectly. I coulda swore I had tried that early on, but I must've had other problems with my code at that point. Now I feel silly.

Although this was five years ago, I'm pretty sure the reason it didn't work for me initially was because I neglected to add multiple='multiple' to the select tag. I know because it happened to me again this morning.
