为什么在MVC中返回视图不起作用？ [英] Why return view in MVC not working?
问题描述
它应该返回页面View而不是弹出哪个完整的HTML代码。
查看
it should returning page View instead of pop-up which full of html code.
View
@model SendAFaxWeb.Models.Home
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>GetHistory</title>
</head>
<body>
<div>
<h2>Fax History List Test</h2>
<form action="@Url.Action("GetHistory", "Home")" id="form" method="post" enctype="multipart/form-data">
<table class="table table-condensed">
@foreach (var item in Model.Documents)
{
<tr>
<td>@item.Name</td>
<td>@item.Path</td>
<td>
<button class="btn btn-xs btn-danger" onclick="d(@item.Name)">
<span class="glyphicon glyphicon-trash"></span>
</button>
</td>
</tr>
}
</table>
</form>
</div>
</body>
</html>
控制器
controller
public ActionResult GetHistory()
{
//some code here
return View(history)//list of object
}
我有什么尝试过：
i试图什么也没有返回，但仍显示弹出式HTML。如何把图像放在这里btw？
What I have tried:
i have tried to return nothing, but still show popup html. how to put an image in here btw?
推荐答案
我猜，你的警告框是一个错误视图（也是HTML格式的）。我会说（在查看我的玻璃球后）你的模型定义不正确。
您的型号参考：
I guess, your alert box is an error view (which is also HTML formatted). I would say (after looking in my glass sphere) your Model definition is not correct.
Your model reference:
@model SendAFaxWeb.Models.Home
看起来也很奇怪。你确定，你的ViewModel被称为Home吗？
你的控制器动作GetHistory
looks very strange as well. Are you sure, your ViewModel is called "Home"?
And your Controller Action "GetHistory"
public ActionResult GetHistory()
{
//some code here
return View(history)//list of object
}
结果如何？你提到的观点？做什么的？再次提交表格？ （......又一次又一次......）
我希望，（假设您的ViewModel名称是主页）你有：
what is its result? Your mentioned view? What for? To submit the form again? (... and again, and again, and again...)
I hope, (assuming your ViewModel name is Home) you have:
// for the very first call
[HttpGet]
public ActionResult GetHistory()
{
SendAFaxWeb.Models.Home history = new SendAFaxWeb.Models.Home();
//some code to set the model properties here
history.Documents = GetDocuments(); // or so...
return View(history)//not a list of objects, but a model containing list of objects
}
//for the posted data from your form
[HttpPost]
public ActionResult GetHistory(SendAFaxWeb.Models.Home history)
{
//some update actions...
//after the job is done, redirect to Index
return RedirectToAction("Index","Home")
}
如果您只需要更新View的一部分，最好使用f。恩。 jquery ajax函数并更新html内容。
示例：
匹配的html元素：
If you need to update just a part of the View, it is better to use f. ex. jquery ajax function and update the html content.
Example:
The matching html element:
<div id="yourdivname">
</div>
javascript / jquery函数（假设，输入文本myParamTextBox具有查询参数：
The javascript / jquery function (assuming, the input text "myParamTextBox" has your parameter for query:
getUpdatedDivContent = function () {
var id =
（ ＃myParamTextBox）。val（）;
("#myParamTextBox").val();
.ajax（{
url：' @ Url.Action（ UpdateMyDivContent，Home）'，
类型：' GET' ，
数据类型：' json'，
traditional： true ，
data：{myparameter：id}，
error： function （data）{
alert（
.ajax({ url: '@Url.Action("UpdateMyDivContent", "Home")', type: 'GET', datatype: 'json', traditional: true, data: { myparameter: id }, error: function (data) { alert(
