使用bootstrap验证程序验证密码和确认密码字段

标签: javascript jquery bootstrapvalidator

我一直坚持通过Jquery添加和删除bootstrap验证器类。我正在添加验证,如果div是可见的,如果div被隐藏则删除。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,验证工作正常。但是确认密码与密码字段的数据不匹配。

请根据div的可见性,帮助我如何匹配密码和确认密码字段?

您可以通过切换.display-none类来实现此目的,如以下示例所示。

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')}`);
}

$('#passwordForm').bootstrapValidator({
      message: 'This value is not valid',
      live: 'enabled',
      fields: {
        password: {
          message: 'The password is not valid',
          validators: {
            notEmpty: {
              message: 'The password is required and cannot be empty'
            },
            identical: {
              field: 'password',
              message: 'The passwords must match. '
            },
            stringLength: {
              min: 6,
              max: 30,
              message: 'The password must be more than 6 and less than 30 characters long'
            },
            regexp: {
              regexp: /^[a-zA-Z0-9_]+$/,
              message: 'The password can only consist of alphabetical, number and underscore'
            }
          }
        },
        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;
}

我的解决方案是将'confirm'-input的类从'form-control'更改为'my-form-control',从中删除属性'required'并添加一个新属性'partner="x " 到初始输入以及确认输入。
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;
          } else {
            p[1].classList.remove('no-match');
            p[1].classList.add('match');
            c = true;
          }
        }

        // Handle changes in the form
        $('[partner]').on('keyup', function() {
          for (i = 0; i < ids.length; ++i) {
            var p = $('[partner=' + ids[i] + ']');
            c = false;
            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)) {
              c = false;
              p[1].classList.remove('match');
              p[1].classList.add('no-match');
            } else {
              c = true;
              p[1].classList.remove('no-match');
              p[1].classList.add('match');
            }
          }
        });

        if (form.checkValidity() === false || c === false) {
          event.preventDefault();
          event.stopPropagation();
        }
        form.classList.add('was-compared');
        form.classList.add('was-validated');
      }, false);
    });
  }, false);
})();
