如何将div内的文本复制到剪贴板?我有一个div，需要添加一个链接，将文本添加到剪贴板。有解决办法吗?
<p class="content">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s</p>
<a class="copy-text">copy Text</a>
在我点击复制文本，然后我按Ctrl + V，它必须被粘贴。

这是一个优雅的Javascript解决方案
<input type="text" value="Foo Bar" id="your_input">
<button onclick="copy()">Copy text</button>
<script type="application/javascript">
function copy() {
var copiedtext = document.getElementById("your_input");
copiedtext.select();
copiedtext.setSelectionRange(0, 99999); //for mobile devices
navigator.clipboard.writeText(copiedtext.value);
alert("You just copied " + copiedtext.value);
}
</script>
剪贴板-填充库是现代基于promise的异步剪贴板API的填充库。
在CLI下安装:
npm install clipboard-polyfill
导入为JS文件中的剪贴板
window.clipboard = require('clipboard-polyfill');
例子
我在一个bundle中使用require("babel-polyfill");并在chrome 67上进行了测试。所有这些都有利于生产。

使用这个函数:
function copy_input($input) {
$input.focus();
$input.select();
try {
var successful = document.execCommand('copy');
} catch(err) {
console.error('Unable to copy');
}
}
电话:
$(".copy-text").on("click",() => {
copy_input("#input_Id")
})
下面是多个答案的组合。这将正确地保存换行符。
// Copies a value to the clipboard
window.copyToClipboard = function(value) {
// navigator clipboard api needs a secure context (https)
if (navigator.clipboard && window.isSecureContext) {
// navigator clipboard api method
return navigator.clipboard.writeText(value).then(function () {
//alert('It worked! Do a CTRL - V to paste')
}, function () {
alert('Error while copying to clipboard.')
});
} else {
// text area method
let textArea = document.createElement("textarea");
textArea.value = value;
// make the textarea out of viewport
textArea.style.position = "fixed";
textArea.style.left = "-999999px";
textArea.style.top = "-999999px";
document.body.appendChild(textArea);
textArea.focus();
textArea.select();
document.execCommand('copy');
textArea.remove();
}
}
