我正在上课,如下
public class UserRoleModel
{
public string Role { get; set; }
public bool UserRole { get; set; }
}
和 public UserRoleModel[] UserRoles { get; set; }
我的控制器如下:
public ActionResult CreateUser()
{
UserDetailsModel model = new UserDetailsModel();
return View(model);
}
[HttpPost]
public ActionResult CreateUser(UserDetailsModel model)
{
return View(model);
}
在我看来,我有
>@foreach (var item in Model.UserRoles)
{
name = "UserRoles"+ ".Value["+ i + "]";
id= "UserRoles" + "_Value[" + i++ + "]";
selected = item.UserRole ? "checked=\"checked\"" : "";
<p> …我有一个sql语句如下:
SELECT [User].[ID],
[User].[Name],
[User].[Email]
FROM [User]
WHERE Email = 'user@home.com''
它从petaPOCO发出如下错误:
参数'@home'指定但没有传递的参数具有此名称的属性(在'SELECT [User].[ID],[User].[Name],[User].[Email] FROM [User] WHERE Email ='user@home.com'')
错误消息意味着什么？sql语句有什么问题？petaPOCO在sql语句中不接受'@'吗？我需要通过电子邮件地址进行搜索.
我如何使用actionResult来返回视图和部分视图.实际上,在ajax请求的情况下,它应该发送部分视图,否则它应该发送视图.
public ActionResult Test(string Name ="", DateTime? Date= null, string sex="" )
{
myModel model = new myModel(Name, Date, Sex);
if(IsAjaxRequest)
return PartialView("partialView", model)
else
return View(model);
}
我有以下代码,我想以一种方式编写它,我有最少的代码行,工作以相同的方式完成.我怎样才能做到这一点？
List<Category> categoryList = new List<Category>();
categoryList = Category.LoadForProject(project.ID).ToList();
List<string> categories = new List<string>(Categories);
IList<Category> currentCategories = Category.LoadForProject(project.ID).ToList();
if (currentCategories != null)
{
foreach (var existingCategories in currentCategories)
{
if (categories.Contains(existingCategories.Name))
categories.Remove(existingCategories.Name);
else
existingCategories.Delete(Services.UserServices.User);
}
foreach (string item in categories)
{
Category category = new Category(project, item.ToString());
category.Project = project;
category.Save();
}
}
List<string> priorities = new List<string>(Priorities);
IList<Priority> currentPriorities = Priority.LoadForProject(project.ID).ToList();
if (currentPriorities != null)
{
foreach (var existingPriorities in currentPriorities)
{
if (priorities.Contains(existingPriorities.Name))
priorities.Remove(existingPriorities.Name);
else
existingPriorities.Delete(Services.UserServices.User);
}
foreach …有人可以向我解释以下方法吗？我不太明白它的作用,以及它是如何做到的.
private List<Label> CreateLabels(params string[] names)
{
return new List<Label>(names.Select(x => new Label { ID = 0, Name = x }));
}
我正在使用jquery自动完成功能,但在文本框中加载自动完成功能很少
我的模型如下:
Users = new List<string>();
foreach (var item in User.LoadSortedByName())
{
Users.Add(item.Name+"\n");
}
视图:
<p>@Html.TextBox("user", "")
$(function () {
$("input#user").autocomplete('@Model.Users');
});
更新 - 简化的尝试,但仍然没有工作
_布局
<script src="@Url.Content("~/Scripts/jquery.autocomplete.js")" type="text/javascript"></script>
View
<p><input type="text" id="tags" /></p>
<script type="text/javascript">
$(function () {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme"
];
$( "#tags" ).autocomplete({
source: availableTags
});
});
我的模型中有一个列表EmployeeList
在我的视图中,我想从EmployeeList(来自Model)填充数组,并将其用作标记的自动完成.似乎数组不是从列表中弹出,也不是自动完成工作.请帮忙.
View中的代码如下:
<title>jQuery Autocomplete example</title>
<script type="text/javascript" src="../../scripts/jquery-1.2.6.js"></script>
<script type="text/javascript" src="../../scripts/jquery.autocomplete.js"></script>
<!-- Listing 14.3 -->
<script type="text/javascript">
$(document).ready(function() {
var employeeList = '@Model.EmployeeLis.toArray();'
$("#tags").autocomplete({
source: employeeList
});
});
</script>
<h1>Type your name here</h1>
<%= Html.TextBox("tags") %>
我做了各种测试,我发现jQuery validate函数只能用于提交按钮.
我对吗？如果是,如何在没有提交按钮的情况下使用jQuery验证插件？
我有十进制？量
在我的模型中,我的值为@ item.Sales,我试图将其写为@ item.Sales.ToString("F2").
我有消息错误错误1方法'ToString'没有重载需要1个参数
我怎样才能实现上述目标
