If you are working in a web development inputs or textarea or div, you might need to create a button like "Copy to Clipboard" to copy all contents of input or div to user's clipboard for making it better for UI. So in this article, I have provided examples for how we can create cop-to-clipboard functionality using Javascript or jQuery in HTML.

Copy to Clipboard using Javascript on Input Element

Let's first create example to copy data from input element. In this we will be using document.execCommand('copy') Browser API which copies contents of HTML input to clipboard

Steps to follow

  • Create a <textarea> and set its contents to the text you want to be copied to the clipboard.
  • Append the textarea to the DOM.
  • Select the text in the textarea using
  • Call document.execCommand("copy") to copy contents from textarea into clipboard
  • Remove the textarea from the document.

Here is the complete Javascript code

function copyToClipboard(text) {
    var sampleTextarea = document.createElement("textarea");
    document.body.appendChild(sampleTextarea);
    sampleTextarea.value = text; //save main text in it
    sampleTextarea.select(); //select textarea contenrs
    document.execCommand("copy");
    document.body.removeChild(sampleTextarea);
}

function myFunction(){
    var copyText = document.getElementById("myInput");
    copyToClipboard(copyText.value);
}

So if our HTML is as below

<input type="text" value="Copy Text value" id="myInput">
<button onclick="myFunction()" >Copy to clipboard</button>

Here is the working Fiddle for it

Copy to Clipboard using Javascript on div/span element

Suppose, you want to copy text from div or span HTML elements into clipboard, then you can use below javascript code, which is almost similar to above approach but few changes

function copyData(containerid) {
  var range = document.createRange();
  range.selectNode(containerid); //changed here
  window.getSelection().removeAllRanges(); 
  window.getSelection().addRange(range); 
  document.execCommand("copy");
  window.getSelection().removeAllRanges();
}

Here is the working fiddle

Output:

If you are using multiple elements for Copy to clipboard functionality, you may want to use below code

unction CopyToClipboard(containerid) {
    if (window.getSelection) {
        if (window.getSelection().empty) { // Chrome
            window.getSelection().empty();
        } else if (window.getSelection().removeAllRanges) { // Firefox
            window.getSelection().removeAllRanges();
        }
    } else if (document.selection) { // IE?
        document.selection.empty();
    }

    if (document.selection) {
        var range = document.body.createTextRange();
        range.moveToElementText(document.getElementById(containerid));
        range.select().createTextRange();
        document.execCommand("copy");
    } else if (window.getSelection) {
        var range = document.createRange();
        range.selectNode(document.getElementById(containerid));
        window.getSelection().addRange(range);
        document.execCommand("copy");
    }
}

Copy to the clipboard using External library

If you don't like the above solutions, and looking for much easier way, then you can use External library like clipboard.js

Using this library you can easily and quickly create copy-to-clipboard functionality, here is the sample HTML code

<script src="https://cdn.jsdelivr.net/npm/clipboard@2.0.8/dist/clipboard.min.js"></script>

<!-- Target -->
<input id="foo" value="Testing ">

<!-- Trigger -->
<button class="btn" data-clipboard-target="#foo">
   Copy
</button>

and you just need below JS code

 var clipboard = new ClipboardJS('.btn');

One of the great features of Clipboard.js is that you can also Cut text from element, or Copy text from attribute.
