我刚刚接手了一个MVC Web应用程序，该员工不再与我工作的公司合作。该应用程序处于早期开发阶段，我注意到一个未解决的错误，即提交＆＃39;按钮触发视图对应的HttpGet ActionResult，而不是HttpPost ActionResult。
他在视图中包含了很多jQuery脚本，我最初怀疑其中一个可能导致问题，但似乎没有一个直接应用于按钮。
Controller（名为HomeController.cs）：
[HttpGet]
public ActionResult Create(string distributorObject)
{
StockLiftObjectView stockLiftObjectView = new StockLiftObjectView();
var userInfo = User.Identity.Name.GetActiveDirectoryInfo();
stockLiftObjectView.txtFirstName = userInfo.FirstName;
stockLiftObjectView.txtLastName = userInfo.LastName;
stockLiftObjectView.txtEmail = userInfo.Email;
if (stockLiftObjectView.RegionId == Guid.Empty)
{
stockLiftObjectView.RegionsList = new SelectList(_stockLiftService.GetRegions(), "Id", "RegionName");
}
return View(stockLiftObjectView);
}
[HttpPost] //Haven't done anything here yet. Ths is never reached
public ActionResult Create(string command, StockLiftObjectView stockLiftObjectView)
{
return View(stockLiftObjectView);
}
查看（名为Create.cshtml）：
@using Html.BeginForm("Create", "Home", FormMethod.Post, new {id = createStockLift}))
{
//left out some non-useful code here
<div class="col-md-offset-2 col-md-10">
<table>
<tr><td><input type="submit" value="Create" name="command" class="btn btn-default" /></td></tr>
<tr><td><input type="submit" value="Save" name="command" class="btn btn-default" /></td></tr>
</table>
</div>
}
我认为可能存在问题的脚本：
<script type="text/javascript">
function getview() {
//runs everytime page loads
$.get("@Url.Action("ShowPartial", "StockLiftAttachmentWebGrid", new List<hpd.Lynx.Web.StockLift.StockLiftAttachmentUpload>()))", function (data) {
$("#stockliftattachmentpartial").replaceWith(data);
$('#createStockLift').submit();
});
};
$("#stockliftattachmentpartial").show();
</script>
对不起，我的问题不是那么具体。在过去的几天里，我一直对这个问题感到困惑，并且想不出一个在谷歌搜索中描述问题的好方法。正如我之前所说，我对jQuery并不熟悉，所以我想我可能会误解一些简单的东西。
更新：
只有在其他时间引用getview（）函数才会在这里......
<input type="submit" value="Upload File" title="Upload" id="btnUpload" onclick="javascript: getview(); return false;" />
所以我不明白为什么它会在页面加载时执行（我从不点击上传按钮）。同样，我的误解来自于从不使用超过基本脚本。
视图中的其他脚本（似乎不适用，但我会以其他方式展示）
<script>
$(function () {
$('#search').click(function () {
var distributorNumber = $("#textboxDistributorNumber").val();
var href = this.href + '?distributorNumber=' + distributorNumber;
@*var url = "@Url.Action("DistributorPartial", "Distributor")"*@
$('#dialog').dialog({
width: 1175,
height: 500,
title: 'Distributor Search',
modal: true,
open: function (event, ui) {
$(".ui-dialog-titlebar-close").hide();
$(this).load(href, function (result) {
$('.forms').submit(function () {
$.ajax({
url: this.action,
type: this.method,
data: $(this).serialize(),
success: function (json) {
debugger;
$('#distributorViewModel_DistributorName').val(json.DistributorName);
}
});
return false;
});
});
}
});
return false;
});
});

答案 0 :(得分：2)
现在看到完整的输出页面HTML，你有嵌套的<form>元素，这些元素无效并可能导致问题。
您需要放置表单，使它们不嵌套在DOM层次结构中。
只是一个理论：但如果我从最初的线索中了解图片，那么当您首先进行“搜索”时，可能会出现问题。这会打开一个对话框，用表单填充它，然后非常愚蠢地将永久submit事件处理程序附加到当前页面上class="forms"所存在的每个表单。
以下将解决一件愚蠢问题：
open: function (event, ui) {
var $panel = $(this);
$(".ui-dialog-titlebar-close").hide();
$panel.load(href, function (result) {
$('.forms', $panel).submit(function () {
修复方法是将范围添加到提交处理程序，例如使用$('.forms', $panel)，因此它不会从页面所有.forms中窃取所有提交内容！它只会在加载的面板中定位.forms。
建议：在任何地方查找使用submit(的任何其他jQuery代码，并将其视为潜在问题。
