client-side-validation

问题 I'm using a DropDownListFor and provide a default selection of -- Select Make -- which has an empty value. I want to provide the user with a hint of what to do (thus the 'Select Make') but don't want to allow them to actually submit that value. Currently the website allows this to go through. I thought that adding a minimum length of 2 would prevent it but no luck. I'm fairly new to .NET MVC so let me know if I'm doing this in the completely wrong way. The actual POST request body is: Make=

问题 I'm trying to get the client_side_validations gem to validate my form in a jquery modal view, but the validations aren't occurring (at least insofar as the errors aren't appearing inline). I'm using the formtastic gem as well, so I've installed client_side_validations and client_side_validations-formtastic gems for formtastic support. Note: I include the rails.validations javascript in my app/views/layouts/application.html.erb Here is my code: app/views/home/index.html.erb: <script type="text

问题 Please check this question before. I frequently heard about "... don't trust the client ! never trust the client ! never trust the user inputs !" I agree with client-side validation alone is a very bad idea. But if so , what is the advantages of using client-side validation ? Is it necessary or not? When should I use client-side validation ? Forget about some bad guys (who try to hack), please think about should every request reach to server side ? I don't think so . Normal users can input

问题 I'm creating a brand new MVC3 site. Client side validation enabled on the web.config <appSettings> <add key="ClientValidationEnabled" value="true"/> <add key="UnobtrusiveJavaScriptEnabled" value="true"/> </appSettings> Scenario #1: Output HTML generated after a failed (client side) validation: <span data-valmsg-replace="true" data-valmsg-for="UserName" class="field-validation-error"> <span htmlfor="UserName" generated="true" class="">Please enter an email address</span> </span> Note the

问题 This is my form: <%= form_for [@company,@company_branch], :html => { :onsubmit => "return validateName();" }, remote: true do |f| %> <%= f.text_field :name %> ... The "validateName" validation works fine when i don't use a remote call. But if do it remote, the form still gets submitted, even if my validation returns false. This is the .js for validation: function validateName() { var name = document.getElementById('name'); if( name.value == "" ) { highlightError(name, "Please provide a name")

问题 I am using jquery.validate in MVC 2 with MicrosoftMvcJQueryValidation. I have data annotations on my model which is then being translated into jquery validators. I am using a modification to MicrosoftMvcJQueryValidation as outlined by Soe Tun to allow my error messages to appear in a validation summary instead of beside the controls. When the page loads, everything works as expected. The problem is that I am using ajax forms with replace mode to rewrite the form. When I do this, I lose all of

问题 From the jquery documentation, describing the remote function of the jquery validate plugin: The response is evaluated as JSON and must be true for valid elements, and can be any false, undefined or null for invalid elements, using the default message; or a string, eg. "That name is already taken, try peter123 instead" to display as the error message. I have a php page that echo's a response, and it works as described if I use echo("true") or echo("false"). However, whenever I echo a string,

问题 I've got a form that I'm submitting based on a div click. I also have it launching a waiting indicator when clicked. I'm trying to find out if there is a way to detect if client side validation failed or not so that I can remove the waiting indicator/never show it after a submit attempt...or can I call the the client side validation manually before I attempt the submit? 回答1: you can try $('div').click(function() { if ($('form').valid()) { //form is valid else{ //invalid form } } }); 来源： https

问题 I am using the SimpleForm, ClientSideValidations, and ClientSideValidations-SimpleForm gems in a RoR application. I can render the form into the modal beautifully, however when the input loses focus no validation occurs and the form is submitted. Also note that I have tried using the fix found here: http://www.ddarrensmith.com/blog/2012/05/17/ruby-on-rails-client-side-validation-with-validation-helpers-and-twitter-bootstrap/ Segment of the view containing the form: <div class='modal hide' id=
