Jquery post array via ajax

Question

I have an array (for checkboxes) that I need to pass alongside the regular form in an ajax post, but can't seem to get this to work:

new_data = [a,b,c,d,e];

somedata_assoc = JQuery.param({'choices[]': new_data});

    $.ajax({
        type: "POST",
     url: contract_qurl,
     data: $(div).find("form").serialize()+"&"+somedata_assoc,
     context: $(this),
     success: function(data) { $("#results_table").html(data); }
    });

Answer 1

I'm getting a javascript error on this line

new_data = [a,b,c,d,e];

I had to change it to this

new_data = ['a','b','c','d','e']; 

you capitalized the J in jQuery in this line

somedata_assoc = JQuery.param({'choices[]': new_data});

should be this (or just the $ shorthand)

somedata_assoc = jQuery.param({'choices': new_data});

also, i dont think you need the brackets, in most cases they would make it more difficult to retrieve the data on the server
