The JavaScript copy function is no longer functioning properly following the update to the href link

I have implemented a function for copying to clipboard as shown below:

function CopyToClipboard(containerid) {
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");
     swal("Signature copied!","Successfully copied to clipboard.", "success");
}}

Currently, I am using an input form to update links in my project. However, the copy function does not seem to work properly after the links are updated. Here is a JavaScript example related to this issue:

$('#fbInput').on('input',function(e){
  var fbInput = $('#fbInput').val();
  textFB.attr("href", fbInput);
  if(fbInput.length > 5 && fbInput.includes("http") !== true) { swal("Include HTTPS.","Start your URL with https://", "warning"); }
});

I would greatly appreciate any advice or solution to resolve this problem. Thank you.

Answer №1

I recently came across a forum post where I learned about using the copy to clipboard function. The original thread can be found here: How to copy text from a div to clipboard

During my research, I encountered a comment suggesting that the function may not work if something is already copied to the clipboard. I am currently exploring this issue further to understand why. Interestingly, I also discovered that attempting to clear the clipboard is not allowed by browsers due to security concerns.
