Parsley + Unable to validate Email address For Full Width Character

Trying to write on Email Validation Check for Full Width Character Parsley :-

JS Code:-

window.Parsley.addValidator('validateFullWidthCharacters', {
  validateString: function(_value) {
    regex = /[\u3000-\u303F]|[\u3040-\u309F]|[\u30A0-\u30FF]|[\uFF00-\uFFEF]|[\u4E00-\u9FAF]|[\u2605-\u2606]|[\u2190-\u2195]|\u203B/;
    if (regex.test(_value)) {
      return false;
    } else {
      return true;
    }
  },
  messages: {
    en: 'Please enter a valid email address.'
  }
});

Works fine and validate the email by giving error message

ｒａｈｕｌ@ｍａｉｌ.ｃｏｍ

but if I changed the email to below one, does not work

rahul@ｍａｉｌ.ｃｏｍ

<input placeholder="e.g. mail@example.com" class="form-control parsley-success" id="user_email" data-parsley-required="" data-parsley-type="email" data-parsley-validate-full-width-characters="true" type="email" value="" name="user[email]" data-parsley-id="17">

Please give suggestion to resolve this.

regex to validate email is:

/^((([a-zA-Z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-zA-Z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-zA-Z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-zA-Z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-zA-Z]|\d|-|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-zA-Z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-zA-Z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-zA-Z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-zA-Z]|\d|-|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-zA-Z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))$/

Your regex just match fullwidth characters, you have to test your value with normal characters.

There is a bug or maybe an "expected behavior" with input type="email", that it converts fullwidth characters into normal ones if it is valid until @.

A solution for you is to change type="email" to type="text" and use another pattern for email and edit that if of you to return regex.test instead

regex = /^([a-z0-9_\.-]+\@[\da-z\.-]+\.[a-z\.]{2,6})$/gm

The new test

regex = /^([a-z0-9_\.-]+\@[\da-z\.-]+\.[a-z\.]{2,6})$/gm
/^([a-z0-9_\.-]+\@[\da-z\.-]+\.[a-z\.]{2,6})$/gm
regex.test('rahul@ｍａｉｌ.ｃｏｍ')
false
regex.test('ｒａｈｕｌ@mail.com')
false
regex.test('rahul@mail.com')
true

your code would become:

window.Parsley.addValidator('validateFullWidthCharacters', {
  validateString: function(_value) {
    regex = /^([a-z0-9_\.-]+\@[\da-z\.-]+\.[a-z\.]{2,6})$/gm;
    return regex.test(_value);
  },
  messages: {
    en: 'Please enter a valid email address.'
  }
});

html

<input placeholder="e.g. mail@example.com" class="form-control parsley-success" id="user_email" data-parsley-required="" data-parsley-type="email" data-parsley-validate-full-width-characters="true" type="text" value="" name="user[email]" data-parsley-id="17"> 


    window.Parsley
        .addValidator('validateFullWidthCharacters', {
            requirementType: 'string',
            validateString: function (value, requirement) {
                regex = /^([a-z0-9_\.-]+\@[\da-z\.-]+\.[a-z\.]{2,6})$/gm;
                return regex.test(value);
            },
            messages: {
                en: 'Please enter a valid email address.'
            }
        });

Before running the validation on the email string try to remove all the extra spaces from the string.

Like this

tr = str.replace(/\s+/g, '');
