我试图找到网上可用的信息,但无法将它连接在一起.我有一个使用登录页面的应用程序.现在我没有将视图绑定到任何模型.但是我有两个输入(用户名和密码).我想解雇
Asp.net Mvc附带的jquery不显眼的验证功能.以下是样本：
带有Twitter引导程序的骨干模板,它是登录模板(下划线模板引擎).
@using (@Html.BeginForm("Login","Home",FormMethod.Post,new { @class = "form-horizontal" }))
{
<div class="modal-body">
<div class="control-group">
<label class="control-label" for="inputEmail">Email</label>
<div class="controls">
@*<input type="text" id="inputEmail" placeholder="Email">*@
@Html.TextBox("Email","",new { @placeholder = "Email" })
</div>
</div>
<div class="control-group">
<label class="control-label" for="inputPassword">Password</label>
<div class="controls">
<input type="password" id="inputPassword" placeholder="Password">
</div>
</div>
<div class="control-group">
@*<div class="controls">
<label class="checkBox">
<input type="checkBox"> Remember me
</label>
<button type="submit" class="btn">Sign in</button>
</div>*@
</div>
</div>
<div class="modal-footer">
@*<a class="btn" href="#" id="closeBtn">Close</a>*@ <button type="submit" class="btn btn-primary" >Login</button>
</div>
}
登录视图的Coffeescript
require ['backbone','bootstrap','jqValUnobtrusive'],(Backbone) ->
class LoginView extends Backbone.View
el:$("#content")
initialize: ->
@render()
@validationoptions = @options.validationoptions
validationoptions:
rules:
'Email':
required:true
'user[password]':
required:true
close:->
console.log "hello"
render : ->
$(@el).find("#login").html _.template $("#loginTemplate").html()
App = new LoginView
我的控制器在没有浏览器的javascript的情况下将服务器端逻辑添加到验证规则
[HttpPost]
[ValidateInput(true)]
public ActionResult Login(FormCollection Form)
{
ViewBag.Message = "Method posted";
if (Form["Email"] == string.Empty)
{
ModelState.AddModelError("Email","Please Provide a Username");
ModelState.SetModelValue("Email",ValueProvider.GetValue("Email"));
}
return View();
}
有人能够对这个问题有所启发吗？如何使用此jquery不显眼的代码来显示twitter引导验证消息以显示错误？或者扩展jquery不显眼的验证插件以使用twitter bootstrap / backbone来执行验证？
我的标准是用户名和密码不应为NULL或空白.研究验证没有模型绑定的表单的简单案例(我不想将Login页面绑定到任何模型).而是通过扩展主干和twitter引导样式来连接jquery不显眼的插件！
解决方法
这是我使用mvc unobtrusive验证时用引导样式替换jquery错误消息的方法：
/*
* Form Validation
* This script will set Bootstrap error classes when form.submit is called.
* The errors are produced by the MVC unobtrusive validation.
*/
$(function () {
$('form').submit(function () {
$(this).find('div.control-group').each(function () {
if ($(this).find('span.field-validation-error').length == 0) {
$(this).removeClass('error');
}
});
if (!$(this).valid()) {
$(this).find('div.control-group').each(function () {
if ($(this).find('span.field-validation-error').length > 0) {
$(this).addClass('error');
}
});
}
});
$('form').each(function () {
$(this).find('div.control-group').each(function () {
if ($(this).find('span.field-validation-error').length > 0) {
$(this).addClass('error');
}
});
});
});
var page = function () {
//Update that validator
$.validator.setDefaults({
highlight: function (element) {
$(element).closest(".control-group").addClass("error");
},unhighlight: function (element) {
$(element).closest(".control-group").removeClass("error");
}
});
} ();
/* End Form Validation */
这个问题的评论中有一些话题,但是这个脚本背后的技术是用Data Annotations(在我的登录案例中为[required])修饰的Asp.Net MVC viewmodel对象,它被传递给View并显示如下(只包括相关位,除非需要更多).
@using (Html.BeginForm())
{
...
<div id="errors"></div>
@Html.ValidationSummary(true,"Sign in was unsuccessful",new { @class = "alert alert-block alert-error" })
<div id="laatikko" class="well">
<div class="control-group">
<label for="kayttajaTunnus" class="control-label">@Kaannokset.Yhteiset.Sähköposti</label>
<div class="controls">
@Html.TextBoxFor(m => m.kayttajaTunnus)
@Html.ValidationMessageFor(m => m.kayttajaTunnus,null,new { @class = "help-inline" })
</div>
</div>
<div class="control-group">
<label for="salasana" class="control-label">@Kaannokset.Yhteiset.Salasana</label>
<div class="controls">
@Html.PasswordFor(m => m.salasana)
@Html.ValidationMessageFor(m => m.salasana,new { @class = "help-inline error" })
</div>
</div>
<input id="signIn" class="btn btn-primary" data-loading-text="Searching for user..." type="submit" value="Sign In" />
}
