ASP.NET MVC +使用jQuery Tab检索一对多关系 [英] ASP.NET MVC + Retrieving one to many relationship using jQuery Tab
问题描述
我有一个表单，该表单的一部分使用 jQuery标签 ="https://github.com/danludwig/BeginCollectionItem" rel ="nofollow noreferrer"> BeginCollectionItem .这是通过一对多关系完成的.我可以在表单中创建多个选项卡并提交(newForm.cshtml).但是，当涉及到编辑时，尤其是当我必须检索表单(带有填充信息的多个选项卡)时，我有点卡在这里.
I have a form that has a section where it uses jQuery tab generated by BeginCollectionItem. This is done by one-to-many relationship. I can create multiple tabs within the form and can submit it (newForm.cshtml). However, when it comes to editing, especially when I have to retrieve the form (with multiple tabs filled with information), I am kinda stuck here.
所以场景很简单.我有一个表，其中显示了已提交表单的列表，并且可以单击一行的编辑链接来编辑检索到的表单.目前，我只能在NewForm中检索名称，而与家庭"选项卡关联的其他名称却无法检索.
So the scenario is simple. I have a table that shows the list of submitted forms and can click an edit link of a row to edit that retrieved form. At this moment, I can only retrieve the Name in NewForm, but other Names associated with Family tabs are not retrieved.
型号:
public class NewForm
{
public int NewFormId { get; set; }
public string Name { get; set; }
public ICollection<Family> Families{ get; set; }
}
public class Family
{
public int FamilyId { get; set; }
public string Name { get; set; }
public int NewFormId { get; set; }
public virtual NewForm NewForm{ get; set; }
}
Edit.cshtml:
Edit.cshtml:
@model Test.Models.NewForm
@using (Html.BeginForm("Edit", "NewForm", FormMethod.Post))
{
<p>Your Name</p>
@Html.EditorFor(m => m.Name)
<button type="button" id="addFamily" name="addFamily">Add Family</button>
<div id="tabs">
<ul>
<li><a href="#tabs-family">Family 1</a></li>
</ul>
<div id="tabs-family">
@Html.Action("AddNewFamily", "NewForm")
</div>
</div>
<button type="submit">Save</button>
}
<script>
$(function () {
var tabTemplate = "<li><a href='#{href}'>#{label}</a></li>",
familyTabCounter = 2,
var tabs = $("#tabs").tabs();
$('#addFamily').on('click', function (event) {
$.ajax({
url: '/NewForm/AddNewFamily',
}).success(function (partialView) {
addTab(partialView, this.url);
});
event.preventDefault();
});
// Actual addTab function: adds new tab using the input from the form above
function addTab(partialView, url) {
if (url == "/NewForm/AddNewFamily") {
var label = "Family " + familyTabCounter,
id = "tabs-family" + familyTabCounter,
li = $(tabTemplate.replace(/#\{href\}/g, "#" + id).replace(/#\{label\}/g, label));
tabs.find(".ui-tabs-nav").append(li);
tabs.append("<div id='" + id + "'><p>" + partialView + "</p></div>");
tabs.tabs("refresh");
familyTabCounter++;
}
}
});
</script>
Family.cshtml:
Family.cshtml:
@model Test.Models.Family
<div class="editorRow">
@using (Html.BeginCollectionItem("families"))
{
@Html.EditorFor(m => m.Name)
}
</div>
控制器:
public PartialViewResult AddNewFamily()
{
return PartialView("~/Views/NewForm/PartialView/Family.cshtml");
}
public ActionResult Edit(int? id)
{
NewForm form = db.NewForms
.Include(i => i.Families)
.Where(x => x.NewFormId == id)
.Single();
return View(form);
}
如何检索与newForm关联的家庭(标签)的信息?
How can I retrieve information for families(tabs) associated with newForm?
修改
@using (Html.BeginForm("Edit", "NewForm", FormMethod.Post))
{
<p>Your Name</p>
@Html.EditorFor(m => m.Name)
<button type="button" id="addFamily" name="addFamily">Add Family</button>
@{int number = 1;}
@foreach (var family in Model.Families)
{
<div id="tabs">
<ul>
<li><a href="#tabs-family">Family @number</a></li>
</ul>
<div id="tabs-family">
@Html.Partial("../NewForm/Family", family)
</div>
</div>
number++;
}
<button type="submit">Save</button>
}
我已经反映了斯蒂芬的建议，并且正在检索多个家庭，但是现在我面临另一个问题，我无法为每个家庭创建每个标签.我尝试使用我的代码，但是它创建了选项卡，但是将其放置在一个奇怪的地方.有什么建议吗?
I've reflected Stephen's advice and retrieving multiple families is working, but now I face another problem that I can't create each tab for each family. I tried with my code, but it creates tab, but it is placed in a weird place. Any suggestions?
推荐答案
您需要使用2个循环为集合中的每个Family生成一个标签，
一个用于创建标头(<li><a>元素)，另一个用于内容(<div>元素.
You need to generate a tabs for each Family in your collection using 2 loops,
one to create the headers (the <li><a> elements), and one for the content (the <div> elements.
请注意，您当前的实现正在生成重复的id属性，并且需要确保每个内容<div>具有唯一的id属性，并且关联的标头<a>元素具有匹配的href值
Note that your current implementation is generating duplicate id attributes, and you need to ensure that each content <div> has a unique id attribute, and that the associated header <a> element has matching href value.
@model Test.Models.NewForm
@{
// Initialize values for loops
int index = 1;
int count = Model.Families.Count() + 1;
}
@using (Html.BeginForm("Edit", "NewForm", FormMethod.Post))
{
<p>Your Name</p>
@Html.EditorFor(m => m.Name)
<button type="button" id="addFamily" name="addFamily">Add Family</button>
<div id="tabs">
<ul>
// Create the tab header for each Family
@for(int i = index; i < count; i++)
{
// Generate unique fragment identifier
string id = String.Format("#family-{0}", i);
<li><a href="@id">Family @i</a></li>
}
</ul>
// Create the content (partial view) for each Family
@foreach(var family in Model.Families)
{
// Generate unique ID
string id = String.Format("family-{0}", index);
<div id="@id">
@Html.Partial("Family", family)
</div>
index++;
}
</div>
<button type="submit">Save</button>
}
旁注:在当前脚本中，您需要使用
设置familyTabCounter
Side note: In your current script, you need to set the familyTabCounter using
var familyTabCounter = @index
，以便单击添加"按钮将基于集合中现有Family的数量生成正确的id属性和关联的片段标识符.
so that clicking the 'Add' button will generate the correct id attribute and associated fragment identifier based on the number of existing Family in the collection.
