What is the best way to transfer a computed result to the clipboard?

After working on a formula to calculate a value, I am now looking to automatically insert that value into an Excel sheet by copying it to the clipboard for user convenience.

In my initial foray into JS, I am facing what seems like a simple issue. I have only come across methods that deal with copying raw values from html input tags, and have not found any solutions for copying values created in JavaScript.

var EEFactor = 1*1; // The formula for calculating a value
copyValue2Clipboard(EEFactor);

function value2Clipboard(value) {
// Seeking assistance
}

Answer №2

Give this a shot.

function copyText(str) {
  var copyEl = document.createElement('textarea');
   // Set the value (string to be copied)
   copyEl.value = str;
   // Make it non-editable to prevent focus and move it out of sight
   copyEl.setAttribute('readonly', '');
   copyEl.style = {position: 'absolute', left: '-9999px'};
   document.body.appendChild(copyEl);
   // Select the text inside the element
   copyEl.select();
   // Copy the text to the clipboard
   document.execCommand('copy');
   // Remove the temporary element
   document.body.removeChild(copyEl);
};

var variable = 1*1;

copyText(variable);

Answer №3

function copyTextToClipboard(text) {
    var copyText = document.createElement("textarea");
    copyText.value = text;
    copyText.setAttribute("readonly", "");
    copyText.style.position = "absolute"
    copyText.style.left = "-9999px";
    document.body.appendChild(copyText);
    var selected =
        document.getSelection().rangeCount > 0
            ? document.getSelection().getRangeAt(0)
            : false;
    copyText.select();
    document.execCommand("copy");
    document.body.removeChild(copyText);
    if (selected) {
        document.getSelection().removeAllRanges();
        document.getSelection().addRange(selected);
    }
}
