在這種情況下，我正在嘗試將 Strong 元素添加到警報框中。但是它回傳“未定義”。
有人可以讓我知道我在這里的語法哪里出了問題。謝謝
$('.copyURL').click(function(e) {
e.preventDefault();
let ele = $(this).parent().siblings(':first-child').children();
let label = $(this).parent().parent().siblings(':first-child').children();
ele[0].select();
ele[0].setSelectionRange(0, 99999);
navigator.clipboard.writeText(ele[0].value);
alert(label[0].value "\r\n" "\r\n"
"Copied: " ele[0].value "\r\n" "\r\n" "Use this link for your WEB site");
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

您需要使用textContent從strong元素中獲取文本，而不是value：
$('.copyURL').click(function(e) {
e.preventDefault();
let ele = $(this).parent().siblings(':first-child').children();
let label = $(this).parent().parent().siblings(':first-child').children();
ele[0].select();
ele[0].setSelectionRange(0, 99999);
navigator.clipboard.writeText(ele[0].value);
alert(label[0].textContent "\r\n" "\r\n"
"Copied: " ele[0].value "\r\n" "\r\n" "Use this link for your WEB site");
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
