I'm using this function to copy a URL to the clipboard:

function CopyUrl($this)\{

var querySelector = $this.next().attr("id");

var emailLink = document.querySelector("\#"+querySelector);

var range = document.createRange();

range.selectNode(emailLink);

window.getSelection().addRange(range);

try \{

// Now that we've selected the anchor text, execute the copy command

var successful = document.execCommand('copy', false, null);

var msg = successful ? 'successful' : 'unsuccessful';

if(true)\{

$this.addClass("copied").html("Copied");

\} catch(err) \{

console.log('Oops, unable to copy');

// Remove the selections - NOTE: Should use

// removeRange(range) when it is supported

window.getSelection().removeAllRanges();

Everything works fine on desktop browsers, but not on iOS devices, where my function returns successfully, but the data isn't copied to the clipboard at all. What's causing this and how could I solve this problem?

There's no problem with your code. However on iOS Safari there are some restrictions (which actually are security measures) to the Clipboard API:

It fires copy events only on a valid selection and cut and paste only in focused editable fields.

It only supports OS clipboard reading/writing via shortcut keys, not through document.execCommand(). Note that "shorcut key" means some clickable (e.g. copy/paste action menu or custom iOS keyboard shortcut) or physical key (e.g. connected bluetooth keyboard).

It doesn't support the ClipboardEvent constructor.

So (at least as of now) it's not possible to programmatically copy some text/value in the clipboard on an iOS device using Javascript. Only the user can decide whether to copy something.
