Passing Arrays to MVC Actions via AJAX: The Traditional Serialization Parameter
This article addresses common challenges when passing arrays from jQuery AJAX to ASP.NET MVC controller actions. When array parameters appear in URLs with bracket notation (e.g., arrayOfValues[]=491), the MVC model binder may fail to parse them correctly. The core solution involves enabling jQuery's traditional serialization mode by setting jQuery.ajaxSettings.traditional = true, which generates query strings without brackets (e.g., arrayOfValues=491&arrayOfValues=368), ensuring compatibility with MVC's IEnumerable<int> parameter type. The article provides an in-depth analysis of traditional serialization mechanics, compares implementations using $.get, $.post, and $.ajax methods, and offers complete code examples with best practices.
