Serialize Form to Array of Objects using jQuery

Question

I am trying to serialize all inputs in a specific form into an object array so that I can pass it to my controller action and then update multiple rows at once. My issue is the serializing part... It's messing up somehow.

Here is where I generate the form:

$.each(content, function (i, item) {
                    var html = "<br />Choice ID<br /><input type='text' name='QuestionChoicesId' value='"
                        + item.QuestionChoicesId + "'><br />Choice Display Text<br /><input type='text' name='DisplayText'  value='"
                        + item.DisplayText + "'><br />Order of Display<br /><input type='text' name='OrderNumber' value='"
                        + item.OrderNumber
                        + "'>";
                    $(html).appendTo("#choices");
                });

This is what i am trying to do:

console.log($('#choices :input').serializeArray());
        $.ajax({
            type: "POST",
            url: "/Question/UpdateQuestionchoices/",
            data: $('#choices :input').serialize()
        });

Here is the console.log output:

output of serialize

It should be an array of objects with QuestionChoicesId, DisplayText, and OrderNumber for each object.

First would suggest you wrap each group, so a loop can be built over the wrappers

$.each(content, function (i, item) {
    var html = '<div class="control_group">';

    /* your exisiting string build code*/

    html += '</div>';
});

To create array:

var ajaxData = $('.control_group').map(function (idx,group) {
    var data = {};
    $(group).find(':input').each(function () {
        data[this.name] = this.value;
    });
    return data;
}).get();

You can use: jquery.serializeToJSON - https://github.com/raphaelm22/jquery.serializeToJSON Its is prepared to work with forms ASP MVC

var obj = $("form").serializeToJSON();

Although it may be structured like that, I think it posts as you would expect. Did you look at how it was posted in the ajax call? I have done the same thing and it worked as expected and bound correctly.

It wasn't mapping correctly in the controller. Kept yelling about NullReferenceException. So, I tracked the problem to the incorrect serialization of my form <div>.
