我正在使用 MVC 4 和 Entity Framework 开发网络应用程序。我有一张包含人员的表格。还有一个调用模态窗口的编辑按钮,用户可以通过它编辑一个人。我正在使用局部 View 来这样做。
我的问题是:在我的操作中,我返回了一个 View ,但我只希望当我单击“保存”按钮时,模态窗口消失并且我的表格被更新。有什么想法吗?
Action :
[HttpGet]
public ActionResult EditPerson(long id)
{
var person = db.Persons.Single(p => p.Id_Person == id);
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
return PartialView("_EditPerson", person);
}
[HttpPost]
public ActionResult EditPerson(Person person)
{
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
if (ModelState.IsValid)
{
ModelStateDictionary errorDictionary = Validator.isValid(person);
if (errorDictionary.Count > 0)
{
ModelState.Merge(errorDictionary);
return View(person);
}
db.Persons.Attach(person);
db.ObjectStateManager.ChangeObjectState(person, EntityState.Modified);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(person);
}
局部 View (其实就是模态窗口):
@model BuSIMaterial.Models.Person
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Edit</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "table"
}))
{
@Html.ValidationSummary()
@Html.AntiForgeryToken()
@Html.HiddenFor(model => model.Id_Person)
<div class="modal-body">
<div class="editor-label">
First name :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.FirstName, new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.FirstName)
</div>
<div class="editor-label">
Last name :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.LastName, new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.LastName)
</div>
<div class="editor-label">

</div>
<div class="editor-field">
@Html.EditorFor(model => model.NumNat, new { maxlength = 11 })
@Html.ValidationMessageFor(model => model.NumNat)
</div>
<div class="editor-label">
Start date :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.StartDate, new { @class = "datepicker", @Value = Model.StartDate.ToString("yyyy/MM/dd") })
@Html.ValidationMessageFor(model => model.StartDate)
</div>
<div class="editor-label">
End date :
</div>
<div class="editor-field">
@if (Model.EndDate.HasValue)
{
@Html.TextBoxFor(model => model.EndDate, new { @class = "datepicker", @Value = Model.EndDate.Value.ToString("yyyy/MM/dd") })
@Html.ValidationMessageFor(model => model.EndDate)
}
else
{
@Html.TextBoxFor(model => model.EndDate, new { @class = "datepicker" })
@Html.ValidationMessageFor(model => model.EndDate)
}
</div>
<div class="editor-label">
Distance House - Work (km) :
</div>
<div class="editor-field">
@Html.EditorFor(model => model.HouseToWorkKilometers)
@Html.ValidationMessageFor(model => model.HouseToWorkKilometers)
</div>
<div class="editor-label">
Category :
</div>
<div class="editor-field">
@Html.DropDownList("Id_ProductPackageCategory", "Choose one ...")
@Html.ValidationMessageFor(model => model.Id_ProductPackageCategory) <a href="../ProductPackageCategory/Create">
Add a new category?</a>
</div>
<div class="editor-label">
Upgrade? :
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Upgrade)
@Html.ValidationMessageFor(model => model.Upgrade)
</div>
</div>
<div class="modal-footer">
<button class="btn btn-inverse" type="submit">Save</button>
</div>
}
</div>
我的脚本调用模态:
$(document).ready(function () {
$('.edit-person').click(function () {
var id = $(this).data("id");
var url = '/Person/EditPerson/'+id;
$.get(url, function(data) {
$('#edit-person-container').html(data);
$('#edit-person').modal('show');
});
});
});
请您参考如下方法:
需要进行一些更改,但在这种情况下我会这样做
1) 将 EditPerson post 方法从 actionresult 更改为 JsonResult
[HttpPost]
public JsonResult EditPerson(Person person)
{
// code here to save person
bool success = true; // somehow determine if the save was successful
string msg = ""; // error message is needed?
return JsonResult(new {success,msg, person});
}
2) 添加一个javascript函数来关闭模态
function closeModal(response){
// the response is the Json Result sent back from the action
if (response.success === true){
// actually got a true response back
}
$('#edit-person').modal('show'); // or similar code
}
3) 然后更新您的 Ajax 调用以在成功时执行代码
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "table",
OnSuccess = "closeModal(response);" // or javascript code to close the modal, you can also
}))
{ ...
一些小技巧
我不喜欢 MVC ajax 助手。我认为它们很臃肿,我觉得还有其他框架在这方面做得更好。那是我的意见。不过对每个人来说。我更愿意自己使用 jQuery ajax 库。我认为它更易于使用,但同样取决于您。
OnSuccess 表示“Server Success”没有保存成功。所以要小心。
免责声明:我写这篇文章时很累,所以可能不会 100% 让我知道任何问题。
祝你好运
