如何将两个相同的对象从视图传递到控制器

Question

我有一个如下的小组：

，视图代码为：

<div class="panel panel-default">
                                <div class="panel-heading" role="tab" id="headingFour">

                                    <h4 class="panel-title">
                                        <a class="collapsed" role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseFour" aria-expanded="false" aria-controls="collapseFour">
                                            Product Details
                                        </a>
                                    </h4>

                                </div>
                                <div id="collapseFour" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingFour">
                                    <div class="panel-body">
                                        <a class="btn btn-lg btn-primary btn-add-panel" > <i class="glyphicon glyphicon-plus"></i> Add new Product</a>
                                        <div id="propanel"></div>
                                        <br />
                                        <div class="panel panel-default template" >

                                            </div>

这个面板可能有一个或多个产品。在viewmodel我得到一个产品类型的对象。我想在插入的产品view中创建列表并将其作为列表传递给控制器​​。我想在视图中创建列表并在其中添加对象 如何插入产品并作为列表发送到controller？

Answer 1

您的基类：

public class JobProduct
{
    public string Detail{get;set;}
    public decimal UnitPrice{get;set;}
    public int Count{get;set;}
}

模特课：

public class JobList
{
    public IEnumerable<JobProduct> JobProductList { get; set; }
}

将get方法中的JobProductList传递给视图：

@for (int i = 0; i < Model.JobProductList.length; i++)
{
        <div id="collapse@(i+1)" class="panel-collapse collapse">
            <div class="panel-body">
                <div class="form-group">
                    @Html.LabelFor(model => model.JobProductList[i].Detail, htmlAttributes: new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.JobProductList[i].Detail, new { htmlAttributes = new { @class = "form-control" } })
                        @Html.ValidationMessageFor(model => model.JobProductList.Detail, "", new { @class = "text-danger" })
                    </div>
                </div>
                <div class="form-group">
                    @Html.LabelFor(model => model.JobProductList[i].UnitPrice, htmlAttributes: new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.JobProductList[i].UnitPrice, new { htmlAttributes = new { @class = "form-control" } })
                        @Html.ValidationMessageFor(model => model.JobProductList[i].UnitPrice, "", new { @class = "text-danger" })
                    </div>
                </div>
                <div class="form-group">
                    @Html.LabelFor(model => model.JobProductList[i].Count, htmlAttributes: new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.JobProductList[i].Count, new { htmlAttributes = new { @class = "form-control" } })
                        @Html.ValidationMessageFor(model => model.JobProductList[i].Count, "", new { @class = "text-danger" })
                    </div>
                </div>
            </div>
        </div>
}

您的最终Create帖子方法应该接受可阻止列表：

[HttpPost]
public ActionResult Create(IEnumerable<JobProductlist> job)
{
    return View(job);
}
