我有下面的代码输入链接从用户创建 anchor href = link

<html>
<head>
    <title>Page Title</title>
    <style>
        #text-input {
            border-left: 4px solid green;
            text-indent: 12px;
        }
    </style>
</head>
<body>
    <p>Enter a link</p>
    <div id="text-input" contenteditable="true"></div>
    
    <script>
      let div = document.getElementById('text-input');
      let anchor;

      div.addEventListener('blur', event => {
        let text = div.innerText;
        div.innerText = '';
        anchor = document.createElement('a');
        div.appendChild(anchor);
        anchor.innerText = text;
        anchor.href = text;
        
        // The below line logs the actual link of the anchor tag
        console.log(anchor.href);
      });
    </script>
</body>
</html>

根据您的默认要求,您可以将https或http附加到输入数据。

 anchor.innerText = text;       
            if(text.indexOf('http://')!=0 || text.indexOf('https://')!=0){
                text = "http://"+text;  //default http(or) https
            }
             anchor.href = text;
