Convert Javascript value into a link?


How am I able to convert the user input into a clickable link within the modal? (user entries will be in a URL format e.g. www.bbc.co.uk). The code I have used is purely from w3c schools and am experimenting how modules could be optimized. I have added the code below.

  <br><b>URL</b> <input type="text" size="40" value="" name="url" id="url" class="form-control" title="Enter the URL of a web page" onchange="displayURL()">

<br><br><br><br><br>
<style>
/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
    font-family: foco;
    
}

/* Modal Content */
.modal-content {
    position: relative;
    background-color: white;
    margin: auto;
    font-size: 15px;
    padding: 0;
    border: 1px solid #888;
    width: 40%;
    
    box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2),0 6px 20px 0 rgba(0,0,0,0.19);
    -webkit-animation-name: animatetop;
    -webkit-animation-duration: 0.3s;
    animation-name: animatetop;
    animation-duration: 0.3s
    
}

/* Add Animation */
@-webkit-keyframes animatetop {
    from {top:-300px; opacity:0} 
    to {top:0; opacity:1}
}

@keyframes animatetop {
    from {top:-300px; opacity:0}
    to {top:0; opacity:1}
}

/* The Close Button */
.close {
    color: white;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: #000;
    text-decoration: none;
    cursor: pointer;
}

.modal-header {
    padding: 2px 16px;
    background-color: #4286f4;
    color: white;
}

.modal-body {padding: 2px 16px;}


}
</style>



<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>

<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <div class="modal-header">
      <span class="close">&times;</span>
      <h2>DEMO</h2>
    </div>
    <div class="modal-body">
      <p>Click on the link:</p>
      <p id="skkr"></p>
      <a id="skkr" href="IM LOST"></a>
      <script>
function displayURL() {
    document.getElementById("skkr").innerHTML = 
document.getElementById("url").value;
}

</script>

    </div>
   
  </div>

</div>

<script>
// Get the modal
var modal = document.getElementById('myModal');

// Get the button that opens the modal
var btn = document.getElementById("myBtn");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal 
btn.onclick = function() {
    modal.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}
</script>

Thanks


Solution

  • It is actually very simple, you have to put the data read from the input box into an anchor tag:

      <br><b>URL</b> <input type="text" size="40" value="" name="url" id="url" class="form-control" title="Enter the URL of a web page" onchange="displayURL()">
    
    <br><br><br><br><br>
    <style>
    /* The Modal (background) */
    .modal {
        display: none; /* Hidden by default */
        position: fixed; /* Stay in place */
        z-index: 1; /* Sit on top */
        padding-top: 100px; /* Location of the box */
        left: 0;
        top: 0;
        width: 100%; /* Full width */
        height: 100%; /* Full height */
        overflow: auto; /* Enable scroll if needed */
        background-color: rgb(0,0,0); /* Fallback color */
        background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
        font-family: foco;
        
    }
    
    /* Modal Content */
    .modal-content {
        position: relative;
        background-color: white;
        margin: auto;
        font-size: 15px;
        padding: 0;
        border: 1px solid #888;
        width: 40%;
        
        box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2),0 6px 20px 0 rgba(0,0,0,0.19);
        -webkit-animation-name: animatetop;
        -webkit-animation-duration: 0.3s;
        animation-name: animatetop;
        animation-duration: 0.3s
        
    }
    
    /* Add Animation */
    @-webkit-keyframes animatetop {
        from {top:-300px; opacity:0} 
        to {top:0; opacity:1}
    }
    
    @keyframes animatetop {
        from {top:-300px; opacity:0}
        to {top:0; opacity:1}
    }
    
    /* The Close Button */
    .close {
        color: white;
        float: right;
        font-size: 28px;
        font-weight: bold;
    }
    
    .close:hover,
    .close:focus {
        color: #000;
        text-decoration: none;
        cursor: pointer;
    }
    
    .modal-header {
        padding: 2px 16px;
        background-color: #4286f4;
        color: white;
    }
    
    .modal-body {padding: 2px 16px;}
    
    
    }
    </style>
    
    
    
    <!-- Trigger/Open The Modal -->
    <button id="myBtn">Open Modal</button>
    
    <!-- The Modal -->
    <div id="myModal" class="modal">
    
      <!-- Modal content -->
      <div class="modal-content">
        <div class="modal-header">
          <span class="close">&times;</span>
          <h2>DEMO</h2>
        </div>
        <div class="modal-body">
          <p>Click on the link:</p>
          <p id="skkr"></p>
          <a id="skkr" href="IM LOST"></a>
          <script>
    function displayURL() {
        var readValue=document.getElementById("url").value;
        document.getElementById("skkr").innerHTML = '<a href="'+readValue+'">'+readValue+'</a>';
    }
    
    </script>
    
        </div>
       
      </div>
    
    </div>
    
    <script>
    // Get the modal
    var modal = document.getElementById('myModal');
    
    // Get the button that opens the modal
    var btn = document.getElementById("myBtn");
    
    // Get the <span> element that closes the modal
    var span = document.getElementsByClassName("close")[0];
    
    // When the user clicks the button, open the modal 
    btn.onclick = function() {
        modal.style.display = "block";
    }
    
    // When the user clicks on <span> (x), close the modal
    span.onclick = function() {
        modal.style.display = "none";
    }
    
    // When the user clicks anywhere outside of the modal, close it
    window.onclick = function(event) {
        if (event.target == modal) {
            modal.style.display = "none";
        }
    }
    </script>

    The important part is:

    var readValue=document.getElementById("url").value;
    document.getElementById("skkr").innerHTML = '<a href="'+readValue+'">'+readValue+'</a>';
