出于某种原因,我的客户端验证似乎不起作用:
这是我的HTML:
@using (Html.BeginForm("Create", "Home", FormMethod.Post))
{
<hr />
@Html.ValidationSummary(true)
<hr />
<p>
<label>Select Client_ID: </label>
<span class="field">
<select name="clientId" id="clientId">
@foreach (var item in Model.ClientId)
{
<option value="@item">@item</option>
}
</select>
</span>
</p>
<p>
<label>@Html.LabelFor(model => model.UserModel.name)</label>
<span class="field">
@Html.EditorFor(model => model.UserModel.name)
</span>
@Html.ValidationMessageFor(model => model.UserModel.name)
</p>
<p>
<label>@Html.LabelFor(model => model.UserModel.password)</label>
<span class="field">
@*<input name="password" id="password" type="password" />*@
@Html.EditorFor(model => model.UserModel.password)
</span>
@Html.ValidationMessageFor(model => model.UserModel.password)
</p>
<p>
<label>@Html.LabelFor(model => model.UserModel.email)</label>
<span class="field">
@*<input name="email" id="email" type="email" />*@
@Html.EditorFor(model => model.UserModel.email)
</span>
@Html.ValidationMessageFor(model => model.UserModel.email)
</p>
<p>
<label>Select: </label>
<span class="field">
<select name="accessLevel" id="accessLevel">
<option value="3">Company</option>
<option value="5">End-User</option>
</select>
</span>
</p>
<input type="submit" value="Submit" />
这是我的模特:
public class CreateUserModel
{
[Required]
[Display(Name = "Client_ID")]
public string clientId { get; set; }
[Required(ErrorMessage = "A name is required")]
[MaxLength(20), MinLength(2, ErrorMessage = "Name must be 2 character or more")]
[Display(Name = "Name")]
public string name { get; set; }
[Display(Name = "Email Address")]
[Required(ErrorMessage = "Email is Required")]
[RegularExpression(@"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" +
@"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" +
@".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
ErrorMessage = "Email is not valid")]
public string email { get; set; }
[Required]
[MaxLength(20), MinLength(6, ErrorMessage = "Password Must be 6 or more chataters long")]
[Display(Name = "Password")]
public string password { get; set; }
[Required]
public int accessLevel { get; set; }
}
我确实在webconfig中启用了客户端:
<appSettings>
<add key="webpages:Version" value="3.0.0.0" />
<add key="webpages:Enabled" value="false" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
{EDIT}添加了渲染的html

由于某些原因,Html助手在输入中没有生成验证属性(data-val =&#34; true&#34;以及其他),请检查。除了检查加载javascript库的顺序之外:
<script src="~/Scripts/jquery.js"></script>
<script src="~/Scripts/jquery.validation.js"></script>
<script src="~/Scripts/jquery.validation.unobtrusive.js"></script>
答案 1 :(得分:10)
您的问题可能是您的文件底部有jQuery,但是您将jquery.validate放在顶部。 jQuery必须在jQuery.validate之前出现。我建议总是把jQuery放在你的标题中,而不是放在正文中,它应该是现代化之后的第一件事。
另外,你知道jQuery 2.x早先不适用于IE8,对吗?

您的jquery.validate.js似乎处于错误的位置。它必须在主jquery ref。
之后对于MVC 5,它应该如下:
_Layout.cshtml:(页面底部)
<body>
...
...
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")
@Scripts.Render("~/bundles/jqueryval") <!-- *required for client side validation! -->
@RenderSection("scripts", required: false)
</body>
其中~/bundles/jqueryval
在 BundleConfig.cs:RegisterBundles()方法中定义:
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.validate*"));

使用:
@Html.EditorFor
而不是:
<input>
当然,您需要jquery.validate.*
脚本
答案 4 :(得分:0)
尝试:您的验证失败,因为您在页面底部对此JQuery链接版本进行了硬编码,该版本可能已更新为Scripts文件夹中的较新版本:
<script src="/Scripts/jquery-2.1.0.js"></script>
您需要做的就是转到“Scripts”,看看是否有“jquery-2.1.0.js”文件,或者您将JQuery更新为更新版本。如果找到,请键入较新的版本文件名,然后重新测试。它现在应该工作。截至2017年6月,我们使用的是JQuery 3.1.1版
这件事发生在我身上,我拉着头发,直到我意识到我已经更新了JQuery并看到它删除了旧版本。我打赌那是你的问题。如果你不这样做,我建议你不要按照查看页面模板粘贴查看页面中的验证脚本,而是创建一个简单的用户控件或母版页或布局视图页面,并在那里填充你的JQuery链接,以便所有人共享它们项目页面。浏览器会自然地第一次缓存这些页面,所以即使它们没有在其他页面上使用,它们也不会再次加载。

不确定是否正在动态加载(例如,使用Ajax加载部分视图)。如果是这样,那么你需要用成功的验证器解析html,例如 使用像...这样的东西。
$.validator.unobtrusive.parse(".target");
E.g。
function loadAPartialView(endPoint) {
$.ajax({
url: endPoint,
type: 'GET',
cache: false,
success: function (result) {
$('.target').html(result);
$('.target').show();
// IMPORTANT. Next line is required to get the client side validation to run.
$.validator.unobtrusive.parse(".target");
$(".loadingMessage").hide();
},
error: function (result) {
// Error message...
$(".loadingMessage").hide();
}
});
};
