在单个字段中验证多个电子邮件地址 [英] Validate multiple email addresses in single field

问题描述

是否可以在单个输入字段中验证一个或多个电子邮件地址?

Is there a way to validate one or multiple email addresses in a single input field?

我目前正在探索的方法是创建一个自定义指令，如果检测到逗号，该指令会将输入拆分为不同的电子邮件.这是我到目前为止的内容:

The way that I'm currently exploring is by creating a custom directive that will split the input into different emails if a comma is detected. This is what I have so far:

angular.module('myApp')
  .directive('multipleEmails', function () {
    return {
      require: 'ngModel',
      link: function(scope, element, attrs, ctrl) {
        ctrl.$parsers.unshift(function(viewValue) {

          var emails = viewValue.split(',');
          // loop that checks every email, returns undefined if one of them fails.
        });
      }
    };
  });

我遇到的问题是我无法手动调用角度电子邮件验证器.

The issue that I have with this is that I have been unable to call the angular email validator manually.

.directive('multipleEmails', function () {
  return {
    require: 'ngModel',
    link: function(scope, element, attrs, ctrl) {
      ctrl.$parsers.unshift(function(viewValue) {

        var emails = viewValue.split(',');
        // loop that checks every email, returns undefined if one of them fails.
        var re = /\S+@\S+\.\S+/;

        // angular.foreach(emails, function() {
          var validityArr = emails.map(function(str){
              return re.test(str.trim());
          }); // sample return is [true, true, true, false, false, false]
          console.log(emails, validityArr); 
          var atLeastOneInvalid = false;
          angular.forEach(validityArr, function(value) {
            if(value === false)
              atLeastOneInvalid = true; 
          }); 
          if(!atLeastOneInvalid) { 
            // ^ all I need is to call the angular email checker here, I think.
            ctrl.$setValidity('multipleEmails', true);
            return viewValue;
          } else {
            ctrl.$setValidity('multipleEmails', false);
            return undefined;
          }
        // })
      });
    }
  };
});
