使用 Partial View、JQuery 和 Bootstrap Modal 编辑记录答案

【问题标题】：Edit Record using Partial View, JQuery and Bootstrap Modal使用 Partial View、JQuery 和 Bootstrap Modal 编辑记录
【发布时间】：2019-04-22 11:23:25
【问题描述】：

我有一个表格，其中最后一列的每条记录都有一个 Edit 按钮。

我的目标是在模式上为用户按下Edit 按钮的记录创建一个可编辑的表单。

为了做到这一点，我创建了一个局部视图，我想将它加载到模态框上，但经过大量尝试后，我无法让它工作。为组成部分视图 URL 并加载到模式中而创建的 JS 似乎没有效果，并且引发以下错误：

VM364 ESa31501901:361 Uncaught ReferenceError: ESa31501901 is not 定义在 HTMLAnchorElement.onclick

注意：ESa31501901是传入JS函数的第一个参数。

这是我的意图：

a) Edit() ：此方法将返回所有记录。

b) EditClientFeature(string ClientID, string WorkProcessID)：此方法将返回包含特定客户端记录的部分视图。当我们开始编辑客户记录时会调用此方法。客户记录以模式（弹出）显示。

c)EditClientFeature(ClientFeatureViewModel model)：此方法将更新客户端记录。

ClientFeature 视图模型

public class ClientFeatureViewModel
{
    public string ClientID { get; set; }
    public string WorkProcessID { get; set; }
    public int? Certification { get; set; }
    public bool? TrackingActive { get; set; }
    public string ClientCode { get; set; }
    public string ContractNo { get; set; }
    public string ProductCode { get; set; }
}

@foreach (var feature in Model.ClientFeatures)
{
 <tr>
     <td style="text-align:center"><strong>@feature.WorkProcessId</strong>/td>

【解决方案1】：

我认为您的onclick 函数参数值被视为变量，而不是字符串。

解决方案 1：

尝试下面作为字符串传递：（虽然没有测试！）

onclick="EditCF(\'' + @Model.Piva + '\', \'' + @feature.WorkProcessId+ '\')"

解决方案 2：

最好在为您的链接添加类之后附加click 处理程序。并使用 HTML5 data attributes 来存储您的价值客户端。

<a href="#" class="btn btn-success editClient" data-ClientID="@Model.Piva" data-WorkProcessId="@feature.WorkProcessId"><i class="glyphicon glyphicon-pencil"></i></a> 


$('.editClient).on('click', function() {
    var clientID = $(this).data('ClientID');
    var workProcessId = $(this).data('WorkProcessId');

    var url = "/Admin/EditClientFeature?ClientID=" + clientID 
    + "?WorkProcessID=" + workProcessID;

    $("#ModalBodyDiv").load(url, function () {

      $("#ModalClientFeatures").modal("show");

    })

});

希望这会有所帮助。

感谢您的提示！我已经尝试过了，它正在工作。模态显示部分视图的内容。但有一个问题。形成的 url 是正确的（我在加载模式之前检查了显示 alert(url);），但是传递给控制器方法的参数是错误的。 ClientID 带有"ESa31501901?WorkProcessID=BCC_BN_FR" 值，WorkProcessID 带有null。你知道为什么吗？
@equisde ，您尝试过解决方案 1 吗？
不！我直接选择了我认为更正确的选项：-D 让我尝试一下，我会返回结果。谢谢！
@equisde 好的，顺便说一下，如果 url 正确，那么它应该将正确的值传递给您的 Action Method。请检查参数名称，它应该匹配。
我终于让它工作了。正如您所说，网址格式错误。已解决var url = "/Admin/EditClientFeature?ClientID=" + ClientID + "&WorkProcessID=" + WorkProcessID;。谢谢大家！
