使用引导验证器验证密码并确认密码字段

【中文标题】使用引导验证器验证密码并确认密码字段【英文标题】：Validate password and confirm password fields using bootstrap validator 【发布时间】：2015-12-11 09:18:18 【问题描述】：我一直坚持通过 Jquery 添加和删除引导验证器类。如果 div 可见，我将添加验证，如果 div 隐藏，则删除。这是我的尝试：
<!--hidden form field-->
<div class="form-group">
<a href="javascript:validateField();" class="theme-color accountFormToggleBtn display-block">click here to change your password</a>
<div class="accountFormToggle display-none" id="passwordForm">
<div class="col-md-5">
<label for="password">Password</label>
<input type='password' id="password" placeholder="Password" name='pass' class="form-control" value='' data-bv-excluded="false" required>
</div>
<div class="col-md-5 col-md-offset-1">
<label for="exampleInputEmail1">Confirm password</label>
<input type='password' id="password2" placeholder="Confirm password" name='password2' class="form-control" value='' data-bv-excluded="false" data-match="#password" required>
</div>
</div>
</div>
JS代码：
function validateField()
if($('#passwordForm').is(':visible'))
$("#password").attr('data-bv-excluded',true);
$("#password2").attr('data-bv-excluded',true);
else
$("#password").attr('data-bv-excluded',false);
$("#password2").attr('data-bv-excluded',false);
如果 div 可见或隐藏，则验证工作。但是确认密码与密码字段的数据不匹配。
请帮助我如何根据 div 的可见性匹配密码并确认密码字段？
【问题讨论】：
@Epodax：如果 php 人员遇到类似问题，我相信他们也可以指导我。没有别的了。 请不要标记与您的问题无关的事物，标记事物是因为您认为该组可以提供帮助不是它是如何工作的. 仅标记与您的问题相关的内容。 我删除了 php 标签，否则你可以添加 asp.net mvc、spring 和很多其他标签。 您能进一步解释一下Please help me how i can match the password and confirm password fields as per visibility of div? 吗？预期的行为是什么，打印的是什么？你能创建一个codepen或类似的吗？
【参考方案1】：
您可以通过切换.display-none 类来实现这一点，如下例所示。
function validateField()
let cont = $('#passwordForm');
if (cont.hasClass('display-none'))
cont.removeClass('display-none');
$("#password").attr('data-bv-validatorname', true);
$("#password2").attr('data-bv-validatorname', true);
else
cont.addClass('display-none');
$("#password").attr('data-bv-validatorname', false);
$("#password2").attr('data-bv-validatorname', false);
console.log(`$("#password").attr('data-bv-validatorname') is $$("#password2").attr('data-bv-validatorname')`);
console.log(`$("#password2").attr('data-bv-validatorname') is $$("#password2").attr('data-bv-validatorname')`);
$('#passwordForm').bootstrapValidator(
message: 'This value is not valid',
live: 'enabled',
fields:
password:
message: 'The password is not valid',
validators:
notEmpty:
message: 'The password is required and cannot be empty'
,
identical:
field: 'password',
message: 'The passwords must match. '
,

max: 30,
message: 'The password must be more than 6 and less than 30 characters long'
,

,
password2:
message: 'The password2 is not valid',
validators:
notEmpty:
message: 'The password2 is required and cannot be empty'
,
identical:
field: 'password',
message: 'The passwords must match. '
,
stringLength:
min: 6,
max: 30,
message: 'The password2 must be more than 6 and less than 30 characters long'
,
regexp:
regexp: /^[a-zA-Z0-9_]+$/,
message: 'The password2 can only consist of alphabetical, number and underscore'
);
$('a.accountFormToggleBtn').on('click', function()
validateField();
); .display-none
display: none;

【参考方案2】：我的解决方案是将“确认”输入的类从“表单控制”更改为“我的表单控制”，从中删除“必需”属性并添加一个新属性“伙伴=”x " 到初始输入和确认输入。 我调整了css并在标准的自执行表单验证js中添加了一些代码（参见下面的示例以及https://jsfiddle.net/HaraldWirth/Loenyxvs/2/）
(function()
'use strict';
window.addEventListener('load', function()
// Fetch all the forms we want to apply custom Bootstrap validation styles to
var forms = document.getElementsByClassName('needs-validation');
// Fetch the partner-IDs of the inputs to be compared against each other
var ids = jQuery.unique($('[partner]').map(function()
return $(this).attr('partner');
).get());
// Loop over them and prevent submission
var validation = Array.prototype.filter.call(forms, function(form)
form.addEventListener('submit', function(event)
var i;
var c = false;
// Handle the initial form
for (i = 0; i < ids.length; ++i)
var p = $('[partner=' + ids[i] + ']');
if ((p[0].value !== '' && p[1].value === '') ||
(p[0].value === '' && p[1].value !== '') ||
(p[0].value === '' && p[1].value === '') ||
(p[0].value !== p[1].value))
p[1].classList.remove('match');
p[1].classList.add('no-match');
c = false;

p[1].classList.remove('no-match');
p[1].classList.add('match');
