一部の外部リンクをこの通知の受信から除外する必要があります

Question

私はこのコードを使用して、サードパーティのサイトに行くことをユーザーに通知していますが、外部の一部のURLを除外したいと考えています。どのようにしてこのコードでそれを行うことができますか？

<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>

サイトがホワイトリスト内にあるかどうかを確認する必要があります。だから、サイトがあればリストをチェックできるようなものを作る必要があります。

ロジックを関数に抽出して、維持しやすくすることをお勧めします。

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.

By clicking OK, you acknowledge this statement.'); 
    }); 
    } 
});
