我能够在我的index.cshtml页面上的表单上最初将视图模型传递给编辑器模板页面。在索引页面上，我有一个提交按钮，将表单结果（编辑器模板中的单选按钮组）发布回控制器，在HttpPost方法中，它将此模型传递给部分视图，该视图显示在模式弹出窗口中。所有这一切都显示了所选的表单元素，但它禁用了用户的单选按钮。用户可以从此处返回（关闭窗口）或确认表单结果。当用户单击确认按钮时，它应该将viewmodel传递回控制器到另一个HttpPost方法，然后该方法将处理表单结果并返回最终的确认视图。但是当我尝试将视图模型从模态弹出窗口传递回控制器时，它不会保留绑定。我试图确保所有内容都通过Hidden输入绑定，但我必须在某处丢失某些内容。也许我会以错误的方式解决这个问题。我只需要基本保持viewmodel绑定从初始帖子，并能够在用户从模态弹出窗口确认选择后处理。什么是最好的方法来实现这一点，而不必在那里进行会话黑客？

@Html.HiddenFor(m => m[i].IsCumulative)

用于更改SharePercentage标签值的jquery脚本
$(function () {
//When 'For' is Selected
$('[class$=PercOfShareFor]').on('click', function (e) {
if ($(this).is(':checked')) {
var forMatches1 = 0;
$('[class$=PercOfShareFor]').each(function (i, val) {
if ($(this).is(':checked')) {
//check how many 'For' Vote Options are selected
forMatches1++;
//select the Share Percentage value label in the same row, and change the class to ForSelected (used as selector)
$(this).closest('td').next('td').next('td').find('.SharePercentage')
.removeClass("SharePercentage")
.addClass("SharePercentageForSelected");
//if the Share Percentage class (used as selector) was previously WithholdSelected then change to ForSelected
$(this).closest('td').next('td').next('td').find('.SharePercentageWithholdSelected')
.removeClass("SharePercentageWithholdSelected")
.addClass("SharePercentageForSelected");
}
});
//divide total 'For' Selections by number of Director Proposals
var forPercent1 = 100 / forMatches1;
//format the percentage to display 2 decimal places if not a whole number
var forPercent2 = Math.round(forPercent1 * 100) / 100;
//Update 'For' Percentages
$('[class$=SharePercentageForSelected]').text(forPercent2);
}
});
//When 'Withhold' is Selected after initially selecting 'For'
$('[class$=PercOfShareWithhold]').on('click', function (e) {
if ($(this).is(':checked')) {
var forMatches = 0;
$('[class$=PercOfShareFor]').each(function (i, val) {
if ($(this).is(':checked')) {
//check how many 'For' Vote Options are still selected
forMatches++;
}
});
var withholdMatches = 0;
$('[class$=PercOfShareWithhold]').each(function (i, val) {
if ($(this).is(':checked')) {
//check how many 'Withhold' Vote Options are still selected
withholdMatches++;
//set the class to WithholdSelected
$(this).closest('td').next('td').find('.SharePercentageForSelected')
.removeClass("SharePercentageForSelected")
.addClass("SharePercentageWithholdSelected")
.text("0"); //Set 'Withhold' Percentage back to 0
}
});
//divide total 'For' Selections by number of Director Proposals
var forPercent1 = 100 / forMatches;
//format the percentage to display 2 decimal places if not a whole number
var forPercent2 = Math.round(forPercent1 * 100) / 100;
//Update 'For' Percentages
$('[class$=SharePercentageForSelected]').text(forPercent2);
}
});
});

你不能通过表格帖子做你想做的事情。浏览器将Post作为完整的HTML页面返回（即使您说它是部分服务器端）。您将需要使用某种形式的JavaScript来完成它，或者您需要使您的确认页面成为实际页面而不是模态弹出窗口。
基本前提是你需要通过javascript捕获提交（或按钮点击）然后显示模态。您可以使用第一个操作的结果填充模态，但您需要通过ajax而不是标准表单帖子提交表单。然后根据他们在模态中的选择，你可以提交或不提交表格。
已有多种资源可供您使用。这是一个展示如何display a confirmation for a delete action的人。然后你可以改变那个javascript，通过ajax加载你的第一个动作的结果，就像这篇关于加载MVC partial views using AJAX或者关于使用jQuery dialog for CRUD operations的关于加载{{3}}的文章一样，这个文章很可能。

模型绑定修复是为BallotViewModel的EditorTemplate添加一个隐藏字段，这样当选择单选按钮时，标签不仅会更改值，而且隐藏字段也会更改值。
编辑模板
@ Html.HiddenFor（m =＆gt; Model.Proposals [i] .SharePercentage，new {@class =＆＃34; hdnSharePercentage＆＃34;}） @ Html.LabelFor（m =＆gt; Model.Proposals [i] .lVoteOptions [j] .SharePercentage，Model.Proposals [i] .lVoteOptions [j] .SharePercentage，new {@class =＆＃34; SharePercentage＆＃34; }）
的jQuery $（本）.closest（＆＃39; TD＆＃39;）。下一个（＆＃39; TD＆＃39;）。下一个（＆＃39; TD＆＃39;）。找到（＆＃39; .hdnSharePercentageWithholdSelected＆＃ 39） .removeClass（＆＃34; hdnSharePercentageWithholdSelected＆＃34） .addClass（＆＃34; hdnSharePercentageForSelected＆＃34）;
