Thank you Eric, that works!
And @Mohammad I have updated my userscript, fix some bug in it
// we won't do copy on select on text editor, otherwise you can't select and
override text in the editor or text inputfunction
checkIfElementIsEditor(element) {
if (!element || !element.nodeName) return false;
const isEditableElement = ['INPUT', 'TEXTAREA',
'BUTTON'].includes(element.nodeName);
if (!isEditableElement) {
if (!element.className || !element.className.toLowerCase) return false;
}
const isTextEditor = element.className.toLowerCase().includes('codemirror');
return isEditableElement || isTextEditor;
}// if we start selection on editor, we prevent the following execution of this
scriptlet copyOnSelectPreventNextCopy =
false;document.addEventListener('mousedown', function onMouseDown() {
const elementsUnderMouse = document.querySelectorAll(':hover');
if (!elementsUnderMouse ||
Array.from(elementsUnderMouse).some(checkIfElementIsEditor)) {
copyOnSelectPreventNextCopy = true;
}
});// Copy on select, copy document selection when mouse button is
updocument.addEventListener('mouseup', function onMouseUp() {
const elementsUnderMouse = document.querySelectorAll(':hover');
if (
copyOnSelectPreventNextCopy ||
!elementsUnderMouse ||
Array.from(elementsUnderMouse).some(checkIfElementIsEditor)
) {
copyOnSelectPreventNextCopy = false;
return;
}
document.execCommand('copy');
});
