How to clear clipboard, javascript?

Question

JavaScript

Dear colleagues, is it possible to clear the buffer using javascript when copying content from the site into it?

Answer 1

Clear clipboard - nothing. Prohibit copying - possible, but not 100%.

Answer 2

The solution consists of two stages.
1. Copying to the clipboard is done like this : document.execCommand('copy')
* but the important condition is that you can copy the text selected by the user.
Therefore, the function of copying text to the clipboard looks like this:
var copyToClipboard = function (text) {
var $txt = $ ('');
$txt.val(text).css({ width: "1px", height: "1px" }).appendTo('body');
$txt.select();
if (document.execCommand('copy')) {
$txt.remove();
}
};
Since copyToClipboard(""); and copyToClipboard(''); - will not copy the void to the buffer.
A space is not empty. Gotta find the void

And we throw it as an argument to the copyToClipboard("⁠");
* Perhaps if you copy the code from the court - it will not work. Therefore, I advise you to manually write everything.
