So I use the following code in php to copy any div, but how can I edit the js code to copy a php variable in the page, like $bookid or $row[1] (or copy/echo two strings like $bookid . $row[1] with one click) etc.?
<button onclick="copyToClipboard('#div1')\">Copy</button>
js code:
function copyToClipboard(element) {
var $temp = $("<input>");
$("body").append($temp);
$temp.val($(element).text()).select();
document.execCommand("copy");
$temp.remove();
}
The text that gets copied here, is the content of the dynamically created input field. Currently that gets set by reading the text content of element - so that is the part that needs replacing.
function copyToClipboard(textToCopy) {
var $temp = $("<input>");
$("body").append($temp);
$temp.val(textToCopy).select();
document.execCommand("copy");
$temp.remove();
}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button onclick="copyToClipboard('hello world')">Copy</button>
