如何使用Ajax將表單值傳遞給控制器​​(控制器部分需要哪種類型來接受發送的數據)

[英]How to pass form value to controller using Ajax (Which type do i need in the controller part to accept sent data)

我想使用serializeArray()方法將我的表單數據轉換為數組,然后我想將它作為參數傳遞給我的控制器的POST方法,但我已經嘗試了字符串,字符串[],對象,對象[]和最后但不是最少問題和問題[] (問題是我的ViewModal描述問題的形狀),但只有問題有效。 但它不適用於視圖中的多個問題。

我做了JSON.stringify($(“ourForm”)。serializeArray()) ,它完成了它的工作但仍然無法將字符串化的數據傳遞給控制器​​。 (嘗試過我在這個平台上看到的String和String [],但它們不起作用。)

我怎么能做這個工作呢,我真的需要一些幫助......

控制器:

[HttpPost]
    public ActionResult CreateExam(String[] formdata) // 
    {
        var abc = formdata;
        return RedirectToAction("index");

    }

Javascript代碼:

$("#submitForm").click(function () {
            var formdata = $("#ourForm").serializeArray();

            $.ajax({
            type: "POST",
                url: "/Teacher/Exam/CreateExam",
                traditional: true,
                data: formdata,
                success: function (data) {
                    alert("BAŞARILI?");
                    // Do something here when it is finished
                }
            });
        });

ViewModal:

public class Questions
    {        
        public IList<Questions> questions { get; set; }
        [Display(Name ="QUESTION GOES HERE")]
        public string question_string { get; set; }
        public string A { get; set; }
        public string B { get; set; }
        public string C { get; set; }
        public string D { get; set; }
        public string E { get; set; }
        [Display(Name ="CORRECT ANSWER")]
        public string correct_answer { get; set; }
    }

我的形式:(我使用了partialview,因為我需要用戶添加他們想要的任意數量的問題,並且我使用了一些JS代碼)

<form class="form-horizontal style-form" id="ourForm">
            <div class="form-panel">
                <button type="button" class="btn btn-success newQuest"><i class="fa-plus">  Yeni Soru Ekle</i></button>
                @Html.Partial("_QuestionLayout", Model)
            </div>
            <button type="button" class="btn btn-primary" id="submitForm">SAVE THE EXAM</button>
        </form>

ViewModal:

<div id="newForm">
    <div class="form-group" style="margin-right: 0px;">
        <div class="col-lg-12">
            <hr />

            <button type="button" class="btn btn-danger delete pull-right"><i class="fa-plus">  SORUYU SİL</i></button>
            <button type="button" class="btn btn-success newQuest pull-right"><i class="fa-plus">  YENİ SORU EKLE</i></button>
            @Html.LabelFor(m => m.question_string, new { @class = "control-label col-md-3" })
            @Html.TextAreaFor(m => m.question_string, new { @class = "form-control", placeholder = "Soru buraya yazılacak.", style = "max-width:100%; min-width:100%" })

        </div>
    </div>
    <div class="form-group">

        <div class="col-md-8 col-xs-11">
            @Html.LabelFor(m => m.A, new { @class = "col-sm-2 col-sm-2 control-label" })
            @Html.TextBoxFor(m => m.A, new { @class = "col-sm-10" })
        </div>
    </div>
    <div class="form-group">

        <div class="col-md-8 col-xs-11">
            @Html.LabelFor(m => m.B, new { @class = "col-sm-2 col-sm-2 control-label" })
            @Html.TextBoxFor(m => m.B, new { @class = "col-sm-10" })
        </div>
    </div>
    <div class="form-group">

        <div class="col-md-8 col-xs-11">
            @Html.LabelFor(m => m.C, new { @class = "col-sm-2 col-sm-2 control-label" })
            @Html.TextBoxFor(m => m.C, new { @class = "col-sm-10" })
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-8 col-xs-11">
            @Html.LabelFor(m => m.D, new { @class = "col-sm-2 col-sm-2 control-label" })
            @Html.TextBoxFor(m => m.D, new { @class = "col-sm-10" })
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-8 col-xs-11">
            @Html.LabelFor(m => m.E, new { @class = "col-sm-2 col-sm-2 control-label" })
            @Html.TextBoxFor(m => m.E, new { @class = "col-sm-10" })
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-8 col-xs-11">
            @Html.LabelFor(m => m.correct_answer, new { @class = "col-sm-2 col-sm-2 control-label" })
            @Html.TextBoxFor(m => m.correct_answer, new { @class = "col-sm-1" })
        </div>
    </div>
</div>

您需要在ajax調用上相應地設置內容類型。

JSON.stringify(formdata)完成這項工作。

AJAX塊上的數據必須是這樣的;

data = {formdata = JSON.Stringify(formdata)}
