问题 I am using client validation rails gem and I got this error. Any idea..... wrong number of arguments (3 for 2) Extracted source (around line #1): <%= form_for @user, :validate => true do |f| %> Trace of template inclusion: app/views/users/new.html.erb 回答1: Based on https://github.com/bcardarella/client_side_validations/issues/494 it looks like CSV will not support Rails 4 for a little bit longer.

问题 Of course, I know that server-side validation is a MUST . I'm using jQuery to validate form inputs and using jquery ajax to do server-side(PHP) validation at the same time. So I guess it may be safe since it's validating for both sides while javascript is enabled . Well, here is my problem... But what if the user has javascript disabled on his browser and if some bad guys try to do something bad from editing my client-side script? Because i'm making server-side validation through jquery ajax,

问题 To keep my model validation clean I would like to implement my own validation attributes, like PhoneNumberAttribute and EmailAttribute . Some of these can favorably be be implemented as simple classes that inherit from RegularExpressionAttribute . However, I noticed that doing this breaks client side validation of these attributes. I am assuming that there is some kind of type binding that fails somewhere. Any ideas what I can do to get client side validation working? Code example : public

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . The argument for using both client side validation (JavaScript) and server side validation using a validator is this: If the client browser does not support JavaScript, then the user cannot use client side validation. My question is how good is this argument in practice? In theory it makes sense, but in practice

问题 Check out the code: <script type="text/javascript"> function ValidateTextBox(source, args) { var is_valid = false; //Regex goes here var regex = /^[a-z A-Z]+$/; var check = regex.test($('tbName').val()); //Checks the tbName value against the regex if (check == true) { //If input was correct is_valid = true; } else { //If input is not correct $("tbName").css(("background-color", "#A00000"), ("border-color", "#780000")); } args.IsValid = is_valid; //Returns validity state } </script> Im trying

问题 I want to run a simple JS function after my .NET validator controls run their javascript. My onsubmit value is javascript:return WebForm_OnSubmit();, which seems to be generated automatically and I can't change it. Am I right in assuming I need to just add a function in this field to get it to work? Also, my form is validating after a field has been changed (not once the form has been submitted), which is great, but is there a setting soimewhere to turn that on/off? Thanks!! 回答1: Althought it

问题 I have huge form that I'd like to split in different steps, but I need to validate the fields in the current step before go to the next step. E.g.: My form has 40 fields, and they are divided in 4 steps (10 fields each). In the HTML the 40 are in the same page, but with jQuery I only show the first 10 and a next button, the fourth page contains the "Submit" button. I need a way to invoke the validation of those ten fields before go to the next step. Is there any way to accomplish this?

问题 I have been learning alot about the standard asp.net Validators, and my latest discovery was about how to disable a validator client side, which was pretty cool. now, if my initial post has the validator enabled, but client side, i disable it, does the server side recognize the client side change, and keep it, or does it get re-enabled the the page is sent back to the user? Thanks! Nate 回答1: .NET Server side validator controls will be reset to whatever they have been set to last in the server
