AJAX Post of JavaScript String Array to JsonResult as List Always Returns Null?

Question

I\'m trying to build up a string array in JavaScript and get the results in a string list in the action method. Below is what my JavaScript looks like. I\'m using jQuery 1

Answer 1

This change was to make native behavior better for PHP/Rails users, you can read about the params changes more here.

You can enable it per-request like this:

$.ajax({ 
 //Stuff...
 traditional:true 
});

Or globally like this (only need to run once before firing any requests):

jQuery.ajaxSettings.traditional = true;

Answer 2

I faced the same problem after updating to jquery 1.4.2. You can find the solution here (in the Ajax section).

Adding traditional : true in the ajax options should work.

$.ajax({
    type: "POST",
    traditional: true,
    url: "/Test/JSONTestAction",
    async: false,
    data: parms,
    dataType: "json",
    success: function(data) {

        // success
    }
});
