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。

更新:现在正确的方法是使用剪贴板API。
例如:
// get the text from the DOM Element:
const textToCopy = document.querySelector('.content').innerText
// when someone clicks on the <a class="copy-text"> element
// (which should be a <button>), execute the copy command:
document.querySelector('.copy-text').addEventListener('click' , ()=> {
navigator.clipboard.writeText(textToCopy).then(
function() {
/* clipboard successfully set */
window.alert('Success! The text was copied to your clipboard')
},
function() {
/* clipboard write failed */
window.alert('Opps! Your browser does not support the Clipboard API')
}
)
})
就是这样。
如果你想看看在Clipboard API引入之前的解决方案(现在不是一个好的实践):
$('button.copyButton').click(function(){
$(this).siblings('input.linkToCopy').select();
document.execCommand("copy");
});
HTML:
<button class="copyButton">click here to copy</button>
<input class="linkToCopy" value="TEXT TO COPY"
style="position: absolute; z-index: -999; opacity: 0;" />

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>
HTML:
// you need bootstrap(js && css) and JQuery(js)
<span class="text-copy" value="your-text">text</span>
CSS:
.text-copy {
cursor: pointer;
color: #0d6efd;
text-decoration: underline;
}
.text-copy:hover {
color: #1b6be4;
}
JS(使用JQuery):
$(document).ready(function() {
var elements = $('.copy-text');
for(let i = 0; i < elements.length; i++) {
const element = $(elements[i]);
element.attr('data-toggle', 'tooltip')
.attr('data-placement', 'top')
.attr('title', `Tab to copy "${element.attr('value')}"`);
}
$('[data-toggle="tooltip"]').tooltip();
$('.text-copy').click(function() {
var $temp = $("<input>");
$("body").append($temp);
$temp.val($(this).attr('value')).select();
document.execCommand("copy");
$temp.remove();
});
});
$(document).ready(async function() { var elements = $('.text-copy'); for(let i = 0; i<elements.length; i++) { const element = $(elements[i]); element.attr('data-toggle', 'tooltip') .attr('data-placement', 'top') .attr('title', `Tab to copy "${element.attr('value')}"`); } $('[data-toggle="tooltip"]').tooltip(); $('.text-copy').click(function() { var $temp = $("<input>"); $("body").append($temp); $temp.val($(this).attr('value')).select(); document.execCommand("copy"); $temp.remove(); }); }); body { display: grid; justify-content: center; } .text-copy { cursor: pointer; color: #0d6efd; text-decoration: underline; } .text-copy:hover { color: #1b6be4; } <html> <head> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css"> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/js/bootstrap.bundle.min.js"></script> </head> <body> <h2 class="text-copy" value="your copy text">your text</h2> <br> <h4>paste here</h4> <input type="text"> </body> </html>
