我有一个很大的形式,它变得太大,所以我想开始使用局部视图来保持清洁。
以下是表单的一小部分,其中显示了主要联系人和替代联系人列表。用户可以添加更多联系人(按钮显示弹出窗口以插入新联系人),用户可以将联系人从活动状态更改为非活动状态(通过表格上的复选框)。现在这是有效的,但就像我说我希望能够使用表格的局部视图。
<div class="box box-primary">
<div class="box-header">
<h3 class="box-title">Contacts</h3>
</div>
<div class="box-body">
<div class="form-group">
<div class="col-xs-4">
<label>Phone:</label>
@Html.EditorFor(model => model.Persons.Phone, new { htmlAttributes = new { @class = "form-control", @id = "phone" } })
@Html.ValidationMessageFor(model => model.Persons.Phone, "", new { @class = "text-danger" })
</div>
<div class="col-xs-8">
<label>Email:</label>
@Html.EditorFor(model => model.Persons.Email, new { htmlAttributes = new { @id = "email", @class = "form-control", @placeholder = "Introduza o email..." } })
@Html.ValidationMessageFor(model => model.Persons.Email, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
<label>Address:</label>
@Html.TextAreaFor(model => model.Persons.Address, new { @class = "form-control", @placeholder = "Introduza a morada...", @rows = 3 })
@Html.ValidationMessageFor(model => model.Persons.Address, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
@if (Model.Contacts != null && Model.Contacts.Count > 0)
{
<table id="example2" class="table table-bordered table-hover dataTable" aria-describedby="example2_info">
<thead>
<tr role="row">
<th class="sorting_asc" role="columnheader" tabindex="0" aria-controls="example2" rowspan="1" colspan="1" aria-sort="ascending">Contact</th>
<th class="sorting" role="columnheader" tabindex="0" aria-controls="example2" rowspan="1" colspan="1">Contact Type</th>
<th class="sorting" role="columnheader" tabindex="0" aria-controls="example2" rowspan="1" colspan="1">Active</th>
</thead>
<tbody role="alert" aria-live="polite" aria-relevant="all">
@{
string cssClass = string.Empty;
string activo = string.Empty;
}
@for (var i = 0; i < Model.Contacts.Count; i++)
{
cssClass = i % 2 == 0 ? "even" : "odd";
<tr class="´@cssClass">
<td class=" ">@Html.DisplayFor(model => Model.Contacts[i].Contact)</td>
<td class=" ">@Html.DisplayFor(model => Model.Contacts[i].contacttypes.Name)</td>
<td class=" ">@Html.CheckBoxFor(model => Model.Contacts[i].IsActive, new { @class = "flat-green" })</td>
</tr>
@Html.HiddenFor(model => Model.Contacts[i].ContactsId)
}
</tbody>
</table>
}
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
<input type="button" value="Add New Contact" class="buttonCreate btn btn-primary btn-sm" />
</div>
</div>
</div>
所以这是使用局部视图的相同HTML
<div class="box box-primary">
<div class="box-header">
<h3 class="box-title">Contacts</h3>
</div>
<div class="box-body">
<div class="form-group">
<div class="col-xs-4">
<label>Phone:</label>
@Html.EditorFor(model => model.Persons.Phone, new { htmlAttributes = new { @class = "form-control", @id = "phone" } })
@Html.ValidationMessageFor(model => model.Persons.Phone, "", new { @class = "text-danger" })
</div>
<div class="col-xs-8">
<label>Email:</label>
@Html.EditorFor(model => model.Persons.Email, new { htmlAttributes = new { @id = "email", @class = "form-control", @placeholder = "Introduza o email..." } })
@Html.ValidationMessageFor(model => model.Persons.Email, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
<label>Address:</label>
@Html.TextAreaFor(model => model.Persons.Address, new { @class = "form-control", @placeholder = "Introduza a morada...", @rows = 3 })
@Html.ValidationMessageFor(model => model.Persons.Address, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
@Html.Partial("ContactListControl", Model.Contacts)
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
<input type="button" value="Add New Contact" class="buttonCreate btn btn-primary btn-sm" />
</div>
</div>
</div>
这是部分视图:
@model List<RecruitmentWeb.Models.contacts>
<table id="example2" class="table table-bordered table-hover dataTable" aria-describedby="example2_info">
<thead>
<tr role="row">
<th class="sorting_asc" role="columnheader" tabindex="0" aria-controls="example2" rowspan="1" colspan="1" aria-sort="ascending">Contato</th>
<th class="sorting" role="columnheader" tabindex="0" aria-controls="example2" rowspan="1" colspan="1">Tipo de Contato</th>
<th class="sorting" role="columnheader" tabindex="0" aria-controls="example2" rowspan="1" colspan="1">Activo</th>
</thead>
<tbody role="alert" aria-live="polite" aria-relevant="all">
@{
string cssClass = string.Empty;
string activo = string.Empty;
}
@for (var i = 0; i < Model.Count; i++)
{
cssClass = i % 2 == 0 ? "even" : "odd";
<tr class="´@cssClass">
<td class=" ">@Html.DisplayFor(model => Model[i].Contact)</td>
<td class=" ">@Html.DisplayFor(model => Model[i].contacttypes.Name)</td>
<td class=" ">@Html.CheckBoxFor(model => Model[i].IsActive, new { @class = "flat-green" })</td>
</tr>
@Html.HiddenFor(model => Model[i].ContactsId)
}
</tbody>
问题
如果用户将联系人从活动状态更改为非活动状态,或者反之亦然,则当我提交表单时,更改不会通过。实际上,该列表为空并且不包含任何信息。如果我不使用局部视图,它可以工作。
那么我错过了什么?
答案 0 :(得分:1)
您只将模型的属性传递给partial,因此您生成的隐藏输入具有名称属性name="[0].ContactsId"
,name="[1].ContactsId"
等,而它们需要为name="Contacts[0].ContactsId"
, name="Contacts[1].ContactsId"
等(同样也是复选框)。
将局部视图模型更改为与主视图相同(您没有表明它是什么),然后将模型传递为
@Html.Partial("ContactListControl", Model)
并调整Html助手以适应。不过,我建议您考虑为EditorTemplate
使用自定义RecruitmentWeb.Models.Contacts
,而不是部分视图。
