Необходимо исключить некоторые внешние ссылки из этого уведомления

Question

Я использую этот код, чтобы уведомить пользователя, что он собирается на сторонний сайт, но я хочу исключить некоторые внешние URL. Как/где я могу это сделать в этом коде?

<script> 
    $('a').each(function() { 
     if (this.href !== "#" && this.href.indexOf('/') !== 0 && this.href.indexOf(location.hostname) === -1) { 
     $(this).attr('target', '_blank') 
      .click(function() {  return confirm('NOTICE: You are leaving our website and will enter a website maintained by a third party. We are providing a link to the third party website solely as a convenience to you, because we believe that website may provide useful content.

     }); 
     } 
    }); 
}); 
</script> 

Answer 1

Вам нужно будет проверить, находится ли сайт в белом списке. Таким образом, вам нужно будет создать что-то, что позволит вам проверить список сайтов.

Я также рекомендую вам извлечь логику в функцию, чтобы сделать ее немного легче поддерживать.

function IsNoticeRequired(url) 
    {  
     // Makes dealing with exclusions easier. 
     url = url.toLowerCase(); 

     // Put the white listed sites here. 
     var excludedSites = 
     [ 
      "stackoverflow.com"  
     ]; 

     // Determine if the site is in the exclusion list. 
     var isInExclusion = false; 
     for(var i = 0; i < excludedSites.length; i++) 
     { 
      // Need to check if url contains site. 
      if(url.indexOf(excludedSites[i]) !== -1) 
      { 
       isInExclusion = true; 
       break; 
      } 
     } 

     var isNoticeRequired = url !== "#"; 
     isNoticeRequired = isNoticeRequired && url.indexOf("/") !== 0 
     isNoticeRequired = isNoticeRequired && url.indexOf(location.hostname) === -1; 
     isNoticeRequired = isNoticeRequired && !isInExclusion; 

     return isNoticeRequired; 
    } 

$('a').each(function() { 
    if (IsNoticeRequired(this.href)) { 
    $(this).attr('target', '_blank') 
     .click(function() {  return confirm('NOTICE: You are leaving our website and will enter a website maintained by a third party. We are providing a link to the third party website solely as a convenience to you, because we believe that website may provide useful content.

    }); 
    } 
});
