JavaScript ENTER key to execute function

I wish to enter input and hit ENTER key to execute a function that provides data back.
Not doing anything else with the mouse or keyboard. I have been trying this which does give me my data back, but I need to use the mouse and keyboard to get my data.
Try to enter "John 3:16-20" to test for the data that comes back.

HTML: 
<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <title>Document</title>

</head>

<body>

  

    <input id="input" type="text" placeholder="Enter a Bible Reference" onkeydown="printInput()" />

    <script>

        function printInput() {

            if (event.key === 'Enter') {

            const input = document.getElementById("input");

            let bob = "https://api.biblia.com/v1/bible/content/KJV.html?passage=" + input.value + "&style=fullyFormatted&key=fd16ea2e32ce50a3cb035f565fcf9f81";

            document.write('<a href="'+bob+'">Get Reference</a>');

            }

        }

    </script>

</body>

</html>

ooooooo so so close to what you need! The only issue here is that document.write overwrites the entire page, which is why you lose the input box and everything else.

Instead, you can create an element on the page to display the link without losing your input field. Here’s an example with a &lt;div&gt; element to show the link:

Code: 
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Bible Reference</title>
</head>

<body>
    <input id="input" type="text" placeholder="Enter a Bible Reference" onkeydown="printInput(event)" />
    <div id="output"></div>

    <script>
        function printInput(event) {
            if (event.key === 'Enter') {
                const input = document.getElementById("input").value;
                let url = "https://api.biblia.com/v1/bible/content/KJV.html?passage=" + input + "&style=fullyFormatted&key=fd16ea2e32ce50a3cb035f565fcf9f81";

                // Display the link in the output div
                document.getElementById("output").innerHTML = `<a href="${url}" target="_blank">Get Reference</a>`;
            }
        }
    </script>
</body>

</html>

What This Does​

  • It checks if the Enter key is pressed.
  • If so, it builds the URL and sets it as the innerHTML of a &lt;div&gt; (with the id="output"), creating a clickable link without refreshing or overwriting the page.
Give that a go, and you should get the link without needing any extra mouse or keyboard actions!
