client-side-validation

问题 while I was working with validation in MVC, and I wrote a custom attribute to validate a property.Initially the client side validation was not working since attribute was not registered.When i clicked on the save button after contacting the server it was showing the error message.So can anyone tell how this server side validation took place instead of client side validation ? attribute usage -> [PhoneNumberHasPlus(ErrorMessage="Invalid number")] public string PhoneNumber {get;set;} attribute

问题 I am using the client_side_validations gem with Rails 3.1.0. I have been trying to use it to validate a hidden field that is set through a javascript widget. From what I have read on the gem's github page, the gem deliberately does not validate hidden fields because the user could not correct these fields. I have unsuccessfully tried to override this behavior. Is there a way to override this behavior for a particular field without modifying the client_side_validations code (other than the

问题 After reading a few question/answers here I have managed to work out how to add a Select list to a form and fill it with data, like so: @Html.DropDownList("S", new SelectList(ViewBag.S, "Id", "Nme"), "-- Sel a S --") And it works perfectly. However I would like to add some client-side Validation To validate whether the user has selected an option and not left it at the Default. I'm using the standard jquery stuff that comes with mvc 3, so presumably I have to do something with HTML

问题 I'm using DataAnnotations to validate my input fields on a MVC3 application. I'm using regular expressions validations. I get the validation messages on the UI for IE8 & IE9. But I notice the difference when I hit the Save button even after the client side validation has failed. IE9 keeps me on the client side. On IE8 however, the control goes to the controller action, and I have to have a controller side TryValidateModel so that the validation errors out. Does anyone know why IE8 is doing a

问题 Is it possible to implement client-site validation for custom ValidationAttribute, which is used in Class scope? For example my MaxLengthGlobal, which should assure global max limit for all input fields. [AttributeUsage(AttributeTargets.Class)] public class MaxLengthGlobalAttribute : ValidationAttribute, IClientValidatable { public int MaximumLength { get; private set; } public MaxLengthGlobalAttribute(int maximumLength) { this.MaximumLength = maximumLength; } public override bool IsValid

问题 I wasn't sure if I could ask this kind of question, but after seeing this on Meta Stackoverflow, it looks like this kind of question is ok. Well, onto my question: A few months ago I wrote a validation framework in Javascript. I know that there already exist validation frameworks like jQuery Validation, but I wanted to take a different approach to validation. Current approaches deal with writing Javascript code to perform validation on form elements. By looking at the form source code, it is

问题 I installed gem 'client_side_validations', run bundle and run rails g client_side_validations:install Installation DIDN"T create any js files, so I created them and put code from HitHub in my assets/javascript folder. added line into application.js //= require rails.validations added line into application.html.erb <%= javascript_include_tag :defaults, "rails.validations", "rails.validations.custom" %> and validation isn't working online(using Devise gem) In my view: <%= form_for resource, ...

问题 I have a framework for client side validation that I'd prefer to use over the existing one that ships with ASP.NET MVC 3. Does anyone know how to disable it in MVC 3? I have tried the following: HtmlHelper.ClientValidationEnabled = false; HtmlHelper.UnobtrusiveJavaScriptEnabled = false; And this in the web.config: <configuration> <appSettings> <add key="ClientValidationEnabled" value="false"/> <add key="UnobtrusiveJavaScriptEnabled" value="false"/> </appSettings> </configuration> Neither have

问题 I have an ASP.NET MVC 4 App that uses the jQuery.validation.js plugin and MVC's jQuery.validation.unobtrusive.js . I use data annotations on my view model to validate a textbox's input to be an integer. This (nested) view is loaded within a parent view using... <% Html.RenderPartial("New"); %> One the first inital page load, client side validation works. But any reloading of the nested view with an ajax call, client side validation no longer works. Why is that? Update : (Code example from

问题 I am trying to use both client_side_validations and devise in my Rails app, and get a weird bug in the log in form. It's says that the email has already been taken and doesn't let the user to log in :) Email is used as the login. This is only when I set the :validate => true. When I turn off the setting :validate => true, the log in is performed successfully. What might cause this problem? 回答1: I got the answer from the author of the client_side_validations: For login form you don't want to
