Copy text from form to clipboard.

[rechmbrs]

I found " A JavaScript scientific calculator." at Javascript Kits http://www.javascriptkit.com/script/cut42.shtml and would like to add a button to copy the results to the clipboard. I have no problem adding the button but writing the copy2clip routine has me lost as the calculator doesn't use the DOM but gets the info from a form.

I appreciate your help.

Add a javascript function

function copyToClip(form)
{
form.display.select();
form.display.setSelectionRange(0, 99999);
document.execCommand("copy");
}

Add a new button

<TD ALIGN="center"><INPUT TYPE="button" VALUE="copy" NAME="copy" ONCLICK="copyToClip(this.form)"></TD>


Please note that this calculator script is quite old and outdated. I'm not sure if there's a newer version available somewhere.

Thanks for the response.

For the function, I found this and it works.

JS FUNCTION:


function copy2Clipboard(input)
{
try
{
navigator.clipboard.writeText(input.value); // Copy text
}
catch (err) // Catch errors
{
alert("Failed to copy: " + err);
}
}


HTML:


<TD ALIGN="center"><INPUT TYPE="button" VALUE="copy" NAME="copy" ONCLICK="copy2Clipboard(this.form)"></TD>


I couldn't get your version to work. This one worked in Chrome and Firefox on win10.

I haven't seen a newer version of the calculator code.
