獲取更多的價值

想不到一個好的標題對不起！它做了什麼！我已經ajson文件看起來有點像這樣：「你累了https://google.com/index.html \ n \ n爲什麼不嘗試https://bing.com/index.html」獲取更多的價值

我想什麼它做的就是點擊鏈接來實現文本對顯示的文本頁面只是成爲url的域名例如google.com

我有它的工作到一個點。很好地得到第一個網址都格式正確，但不是第二個。

var url = "You tired of https://google.com/index.html \n\n why not try https://bing.com/index.html "; 
 
linkify(url); 
 
    function linkify(url) { 
 
     
 
     alert(url); 
 
     
 
      var domain; 
 
      //find & remove protocol (http, ftp, etc.) and get domain 
 
      if (url.indexOf("://") > -1) { 
 
       domain = url.split('/')[2]; 
 
      } 
 
      else { 
 
       domain = url.split('/')[0]; 
 
      } 
 

 
      //find & remove port number 
 
      domain = domain.split(':')[0]; 
 
     alert(domain); 
 
    
 
     var replacedText, replacePattern1, replacePattern2, replacePattern3; 
 

 
     //URLs starting with http://, https://, or ftp:// 
 
     replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim; 
 
     replacedText = url.replace(replacePattern1, '<a href="$1" target="_blank">'+domain+'</a>'); 
 

 
     //URLs starting with "www." (without // before it, or it'd re-link the ones done above). 
 
     replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim; 
 
     replacedText = replacedText.replace(replacePattern2, '$1<a href="http://$2" target="_blank">'+domain+'</a>'); 
 

 
     //Change email addresses to mailto:: links. 
 
     replacePattern3 = /(([a-zA-Z0-9\-\_\.])[email protected][a-zA-Z\_]+?(\.[a-zA-Z]{2,6})+)/gim; 
 
     replacedText = replacedText.replace(replacePattern3, '<a href="mailto:$1">$1</a>'); 
 

 
     
 
     document.getElementById('out').innerHTML = replacedText;}

<span id="out"></span>

我看到你已經解決您的問題。但我想我會發布我的解決方案。誰知道，你可能會更喜歡它。希望能幫助到你。

https://jsfiddle.net/90m6ss8b/2/

var url = "You tired of https://google.com/index.html \n\n why not try https://bing.com/index.html "; 
linkify(url); 

function linkify(url) { 
    var matches = url.match(/(?:(?:https?|ftp|file):\/\/|www\.|ftp\.)(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[-A-Z0-9+&@#\/%=~_|$?!:,.])*(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[A-Z0-9+&@#\/%=~_|$])/igm); 

    alert(matches); 

    for (i = 0; i < matches.length; i++) { 
    if (matches[i].indexOf("://") > -1) { 
     alert(matches[i]); 
     matches[i] = matches[i].split('/')[2]; 
     alert(matches[i]); 
    } 
    } 

    alert(matches); 

    var replacedText, replacePattern1, replacePattern2, replacePattern3; 
    replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/im; 
    replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/im; 
    replacePattern3 = /(([a-zA-Z0-9\-\_\.])[email protected][a-zA-Z\_]+?(\.[a-zA-Z]{2,6})+)/im; 

    replacedText = replaceIndex(url, replacePattern1,'<a href="$1" target="_blank">' + matches[0] + '</a>'); 
    replacedText = replaceIndex(replacedText, replacePattern2,'$1<a href="http://$2" target="_blank">' + matches[0] + '</a>'); 
    replacedText = replaceIndex(replacedText, replacePattern3, '<a href="mailto:$1">$1</a>'); 
    replacedText = replaceIndex(replacedText, replacePattern1,'<a href="$1" target="_blank">' + matches[1] + '</a>'); 
    replacedText = replaceIndex(replacedText, replacePattern2,'$1<a href="http://$2" target="_blank">' + matches[1] + '</a>'); 
    replacedText = replaceIndex(replacedText, replacePattern3, '<a href="mailto:$1">$1</a>'); 

    function replaceIndex(string, pattern, repl) { 
    return string.replace(pattern, function(match, i) { 
     if (i === match) return repl; 
     return match; 
    }); 
    } 

    document.getElementById('out').innerHTML = replacedText; 
}

它運作良好。謝謝，但是當鏈接的數量與發佈後的數量不同時，它可能會有點擊或錯過。我知道我可以改變[1]到[2]等等。你的方式是更有條理的，我的更多是一個保險工作。 –

var url = "You tired of https://google.com/index.html \n\n why not try https://bing.com/index.html "; 
 
    linkify(url); 
 
    function linkify(url) { 
 

 

 
     var replacedText, replacePattern1, replacePattern2, replacePattern3, i; 
 

 
     //URLs starting with http://, https://, or ftp:// 
 
     replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim; 
 
     replacedText = url.replace(replacePattern1, '<a href="$1" class="urlcouint" target="_blank" id="xurl">$1</a>'); 
 

 
     //URLs starting with "www." (without // before it, or it'd re-link the ones done above). 
 
     replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim; 
 
     replacedText = replacedText.replace(replacePattern2, '$1<a href="http://$2" target="_blank">$1</a>'); 
 

 
     //Change email addresses to mailto:: links. 
 
     replacePattern3 = /(([a-zA-Z0-9\-\_\.])[email protected][a-zA-Z\_]+?(\.[a-zA-Z]{2,6})+)/gim; 
 
     replacedText = replacedText.replace(replacePattern3, '<a href="mailto:$1">$1</a>'); 
 

 

 
     document.getElementById('out').innerHTML = replacedText;} 
 
    
 
     var nubero = ($('a.urlcouint').length); 
 
     for(var i = 0; i < nubero; i++) { 
 
      var domain, url; 
 
      url = document.getElementById('xurl').href; 
 
     //find & remove protocol (http, ftp, etc.) and get domain 
 
     if (url.indexOf("://") > -1) { 
 
      domain = url.split('/')[2]; 
 
     } 
 
     else { 
 
      domain = url.split('/')[0]; 
 
     } 
 

 
     //find & remove port number 
 
     domain = domain.split(':')[0]; 
 
     alert(domain); 
 
     document.getElementById('xurl').innerHTML = domain; 
 
     document.getElementById('xurl').setAttribute('id', 'xurldone');}
