我怎样才能进入html <tr>对象

How can i get into the value inside of an html <tr> object

本文关键字：tr 对象 html 更新时间：2023-09-26

所以我有这个代码。我想把html输入中的数据发送给控制器参数。在我的jquery中，我有这样一行
var currentRow = $(this).close ("tr");但是我不知道如何进入currentRow对象内的每个输入的值，我怎么能做到这一点，或者你可能知道一个更好的方法来做到这一点?

 // my html
@foreach (var discount in Model.DiscountList)
        {
            <tr>
                <td>@Html.TextBox("codeTextBox", discount.Code) </td>
                <td><input type="checkbox" name="freeShippingCheckBox" id="freeShippingCheckBox" checked="@discount.FreeShipping" /> </td>
                @if (discount.isTwoForThree == true)
                {
                    <td><input type="tel" value="Ta 3 betala för 2" readonly /></td>
                }
                else
                {
                    <td><input type="number" value="@discount.PercentOffPrice"/></td>
                }
                <td><input type="checkbox" id="activeCheckBox" name="activeCheckBox" checked="@discount.Active" /></td>
                <td><input type="datetime" value="@discount.CreatedDate" readonly /></td>
                <td>
                    <input type="button" value="Radera" class="fa fa-remove" data-url="@Url.Action("DeleteDiscountCode","Discount",new { id= discount.Id})" />
                    <input type="button" value="Uppdatera" class="fa fa-update" data-url="@Url.Action("UpdateDiscount","Discount",new { id= discount.Id, })" />
                    <input type="button" value="Produkter" class="fa fa-products" />
                </td>
                <input id="@discount.Id.ToString()" type="hidden" value="@discount.Id" />
            </tr>
        }

//my jquery  
          $(".fa-update").on("click", function () {
            var currentRow = $(this).closest("tr");
            console.log(currentRow.children("#freeShippingCheckBox").val());
            if (confirm("Are you sure you want to edit this discount code?"))
            {
                $.post($(this).data("url"), function (data) {
                    $.ajax({
                        url: '@Url.Action("DeleteUser","Discount")',
                        type: "POST",
                        data: "freeShipping=..........???????????",
                        success: function (data) {
                            if (data) {
                            }
                            location.reload();
                        }
                    });
                    location.reload();
                    alert("Deleted");
                })
            }
        });

 //my controller
    [HttpPost]
    public void UpdateDiscount(int id, bool freeShipping, int percentOfPrice, bool active)
    {
        Service.DiscountService.UpdateDiscount(id, freeShipping, percentOfPrice, active);
    }

我的建议是:

$(function () {
  $(".fa-update").on("click", function (e) {
    var data = {};
    var currentRowParams = $(this).closest("tr").find('input').each(function(index, element) {
      var name = element.name ? element.name : 'undefined' + index;
      data[name] = element.value || '';
    });
    var x =  JSON.stringify(data);
    console.log(x);
    
    //
    // If instead you want the params in a traditional GET
    //
  });
});

<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<table>
    <tbody>
    <tr>
        <td>@Html.TextBox("codeTextBox", discount.Code) </td>
        <td><input type="checkbox" name="freeShippingCheckBox" id="freeShippingCheckBox" checked="@discount.FreeShipping" /> </td>
        <td><input type="tel" value="Ta 3 betala for 2" readonly /></td>
        <td><input type="checkbox" id="activeCheckBox" name="activeCheckBox" checked="@discount.Active" /></td>
        <td><input type="datetime" value="@discount.CreatedDate" readonly /></td>
        <td>
            <input type="button" value="Radera" class="fa fa-remove" data-url="@Url.Action("DeleteDiscountCode","Discount",new { id= discount.Id})" />
            <input type="button" value="Uppdatera" class="fa fa-update" data-url="@Url.Action("UpdateDiscount","Discount",new { id= discount.Id, })" />
            <input type="button" value="Produkter" class="fa fa-products" />
        </td>
        <input id="@discount.Id.ToString()" type="hidden" value="@discount.Id" />
    </tr>
    </tbody>
</table>

可以通过.html()访问值。正如Vijai所说，您可以使用serialize使其成为POST数组，如(&=等)格式，假设您有结构化表单。或者，为了保持与原始代码相似，您可以像往常一样传递JSON。像

data:{shippingInfo: "value", moreInfo: "blahblah"}

如果您不处理视图中的输入值，建议在您的输入周围使用<form id="formID" ...>标记，并在Ajax方法中使用$("#formID").serialize()。参考这个示例链接:使用AJAX和jQuery提交表单

$.post($(this).data("url"), function (data) {
                    $.ajax({
                        url: '@Url.Action("DeleteUser","Discount")',
                        type: "POST",
                        data: $("#formID").serialize(),
                        success: function (data) {
                            if (data) {
                            }
                            location.reload();
                        }
                    });
