Rails-多步骤表单中的客户端验证问题

Question

我在rails中有一个表单，它是一个多步骤表单，我已经使用了这个'client_side_validations', github: "DavyJonesLocker/client_side_validations", branch: "4-2-stable"

的形式是

    <%= form_for @employee, :html => {:multipart => true, :id => 'msform'}, :validate => true do |f| %>
      <%= render 'shared/error_messages', :target => @employee %>
      <ul id='progressbar'>
        <li class='active'>Account</li>
        <li>Address</li>
        <li>Contact</li>
      </ul>
      <!-- fieldsets -->
      <fieldset>
        <h2 class='fs-title margin_0 bg_red white-text left-align margin_B20'>Create
          Account</h2>

        <div class='row form_row padding_L20 padding_R20 margin_B15'>
          <div class='col s12 m4 left-align'>
            <label for='usrname' class='form_label'>User Name</label>
          </div>
          <%= f.fields_for :profile do |p| %>
            <div class='col s12 m8'>
              <div class='input-field'>
                <%= p.text_field :name, :validate => true, :class => 'validate form_input' %>
              </div>
            </div>
          <% end %>
        </div>
        <div class='row form_row padding_L20 padding_R20 margin_B15'>
          <div class='col s12 m4 left-align'>
            <label class='form_label'>Email</label>
          </div>
          <div class='col s12 m8'>
            <div class='input-field'>
              <%= f.text_field :email, :validate => true, :class => 'validate form_input' %>
            </div>
          </div>
        </div>
        <div class='row form_row padding_L20 padding_R20 margin_B15'>
          <div class='col s12 m4 left-align'>
            <label class='form_label'>Role</label>
          </div>
          <div class='col s12 m8'>
            <div class='input-field'>
              <%= f.select :role, Employee.roles.keys, :selected => @employee[:role],
                           :class => 'browser-default' %>
            </div>
          </div>
        </div>

          <div class='row form_row padding_L20 padding_R20 margin_B15'>
            <%= f.fields_for :contact do |c| %>
              <div class='col s12 m4 left-align'>
                <label for='phno' class='form_label'>Phone Number</label>
              </div>
              <div class='col s12 m8'>
                <div class='input-field'>
                  <%= c.text_field :phone_no, :class => 'validate form_input' %>
                </div>
            <% end %>
            </div>
          </div>
          <input type='button' id="next_form" name='next' class='next action-button' value='Next'/>
        <% end %>

 </fieldset>
  <fieldset>
    <h2 class='fs-title margin_0 bg_red white-text left-align margin_B20'>Create
      Address</h2>

    <h3 class='fs-subtitle left-align margin_0'>Current Address</h3>
    <%= f.fields_for :contact, :validate => true do |c| %>
      <div class='row form_row padding_L20 padding_R20 margin_B15'>
        <div class='col s12 m4 left-align'>

          <div class='input-field'>
            <%= c.text_field :current_address1, :class => 'validate form_input',
                             :id=> 'current-address-1', :validate => true %>
          </div>
        </div>
      </div>
      <div class='row form_row padding_L20 padding_R20 margin_B15'>
        <div class='col s12 m4 left-align'>

          <div class='input-field'>
            <%= c.text_field :current_address2, :class => 'validate form_input',
                             :id=> 'current-address-2' %>
          </div>
        </div>
      </div>
      <div class='row form_row padding_L20 padding_R20 margin_B15'>
        <div class='col s12 m12 left-align'>
          <div class='row'>
            <div class='input-field col s12 m6'>
              <%= c.country_select :country, {prompt: 'Please select a country'}, {:class => 'browser-default'}, {:validate => true} %>
            </div>

            <div class='input-field col s12 m6'>
              <%= render partial: 'subregion_select', locals: {parent_region: c.object.country} %>
            </div>
          </div>
        </div>
      </div>

      <div class='row form_row padding_L20 padding_R20 margin_B15'>
        <div class='col s12 m12 left-align'>
          <div class='row'>
            <div class='input-field col s12 m6'>
              <%= c.text_field :city, :class => 'validate form_input', :placeholder =>'City',
                               :id=>'curr-city', :validate => true %>
            </div>
            <div class='input-field col s12 m6'>
              <%= c.text_field :zip, :class => 'validate form_input', :placeholder =>'Zip Code',
                               :id=>'curr-zip', :validate => true %>

            </div>
          </div>
        </div>
      </div>
    <% end %>

表单ID为#msform，下一个按钮ID为#next_form，所以现在我按照多步表单进行了客户端验证，并将javascript代码作为

$("#next_form").bind("click", function(e) {
    //If the form is valid then go to next else don't
    var valid = true;
    // this will cycle through all visible inputs and attempt to validate all of them.
    // if validations fail 'valid' is set to false
    $('[data-validate] input:visible').each(function() {
        var settings = window.ClientSideValidations.forms[this.form.id]
        if (!$(this).isValid(settings.validators)) {
            valid = false
        }
    });
    if(valid){
        //code to go to next step
        $("#msform").enableClientSideValidations();
    }
    // if any of the inputs are invalid we want to disrupt the click event
    return valid;
});

我在第一个表单中收到错误消息，但是当我单击下一个表单时，另一步表单出现在客户端验证中，因此我无法解决此问题，因为3天了，请帮忙！

Answer 1

验证程序有可能出错，因为您在按钮事件上使用了'this'变量。 尝试使用特定的表单选择器，如下所示：

var form = $('#msform');
var form_validators = ClientSideValidations.forms[form.attr('id')].validators
if (!form.isValid(form_validators)) {
  valid = false;
}

在显示表单后，也请尝试重置验证器：

if(valid){
  $("#msform").resetClientSideValidations();
  $("#msform").enableClientSideValidations();
}
