推荐答案
这是可以帮助你或将来的功能引荐。
Here is the function which might can help you or future referer.
function copyToClipboard(id) {
var text = $("#td_id_" + id).text(); //getting the text from that particular Row
//window.prompt("Copy to clipboard: Ctrl+C, Enter", text);
if (window.clipboardData && window.clipboardData.setData) {
// IE specific code path to prevent textarea being shown while dialog is visible.
return clipboardData.setData("Text", text);
} else if (document.queryCommandSupported && document.queryCommandSupported("copy")) {
var textarea = document.createElement("textarea");
textarea.textContent = text;
textarea.style.position = "fixed"; // Prevent scrolling to bottom of page in MS Edge.
document.body.appendChild(textarea);
textarea.select();
try {
return document.execCommand("copy"); // Security exception may be thrown by some browsers.
} catch (ex) {
console.warn("Copy to clipboard failed.", ex);
return false;
} finally {
document.body.removeChild(textarea);
}
}
}
