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。

大多数建议的答案都会创建一个额外的临时隐藏输入元素。因为现在大多数浏览器都支持div内容编辑，所以我提出了一个解决方案，它不创建隐藏元素，保留文本格式，并使用纯JavaScript或jQuery库。
下面是一个使用我能想到的最少代码行的极简框架实现:
//Pure javascript implementation: document.getElementById("copyUsingPureJS").addEventListener("click", function() { copyUsingPureJS(document.getElementById("copyTarget")); alert("Text Copied to Clipboard Using Pure Javascript"); }); function copyUsingPureJS(element_id) { element_id.setAttribute("contentEditable", true); element_id.setAttribute("onfocus", "document.execCommand('selectAll',false,null)"); element_id.focus(); document.execCommand("copy"); element_id.removeAttribute("contentEditable"); } //Jquery: $(document).ready(function() { $("#copyUsingJquery").click(function() { copyUsingJquery("#copyTarget"); }); function copyUsingJquery(element_id) { $(element_id).attr("contenteditable", true) .select() .on("focus", function() { document.execCommand('selectAll', false, null) }) .focus() document.execCommand("Copy"); $(element_id).removeAttr("contenteditable"); alert("Text Copied to Clipboard Using jQuery"); } }); #copyTarget { width: 400px; height: 400px; border: 1px groove gray; color: navy; text-align: center; box-shadow: 0 4px 8px 0 gray; } #copyTarget h1 { color: blue; } #copyTarget h2 { color: red; } #copyTarget h3 { color: green; } #copyTarget h4 { color: cyan; } #copyTarget h5 { color: brown; } #copyTarget h6 { color: teal; } #pasteTarget { width: 400px; height: 400px; border: 1px inset skyblue; } <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="copyTarget"> <h1>Heading 1</h1> <h2>Heading 2</h2> <h3>Heading 3</h3> <h4>Heading 4</h4> <h5>Heading 5</h5> <h6>Heading 6</h6> <strong>Preserve <em>formatting</em></strong> <br/> </div> <button id="copyUsingPureJS">Copy Using Pure JavaScript</button> <button id="copyUsingJquery">Copy Using jQuery</button> <br><br> Paste Here to See Result <div id="pasteTarget" contenteditable="true"></div>

你可以使用这个库轻松实现复制目标!

将文本复制到剪贴板应该不难。它不需要 数十个配置步骤或数百kb的加载。但是大部分 总之，它不应该依赖于Flash或任何膨胀的框架。 这就是clipboard.js存在的原因。

ZeroClipboard库提供了一种简单的方法来将文本复制到 剪贴板使用一个不可见的Adobe Flash电影和JavaScript 接口。
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();
}
}
两者都会有魅力:)，
JAVASCRIPT:
function CopyToClipboard(containerid) {
if (document.selection) {
var range = document.body.createTextRange();
range.moveToElementText(document.getElementById(containerid));
range.select().createTextRange();
document.execCommand("copy");
} else if (window.getSelection) {
var range = document.createRange();
range.selectNode(document.getElementById(containerid));
window.getSelection().addRange(range);
document.execCommand("copy");
alert("text copied")
}}
在html中，
<button id="button1" onclick="CopyToClipboard('div1')">Click to copy</button>
<div id="div1" >Text To Copy </div>
<textarea placeholder="Press ctrl+v to Paste the copied text" rows="5" cols="20"></textarea>
JQUERY: https://paulund.co.uk/jquery-copy-clipboard
这里是HTML代码
<input id="result" style="width:300px"/>some example text
<button onclick="copyToClipboard('result')">Copy P1</button>
<input type="text" style="width:400px" placeholder="Paste here for test" />
JS代码:
function copyToClipboard(elementId) {
// Create a "hidden" input
var aux = document.createElement("input");
aux.setAttribute("value", document.getElementById(elementId).value);
// Append it to the body
document.body.appendChild(aux);
// Highlight its content
aux.select();
// Copy the highlighted text
document.execCommand("copy");
// Remove it from the body
document.body.removeChild(aux);
}
我刚才正在做，我只是想知道有没有比我更好的方法，但是没有。
你可以使用我的代码，它复制文本并显示一个工具提示。
