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>

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;" />
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();
}
}
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"); $temp.remove(); }); }); body { display: grid; justify-content: center; } .text-copy { cursor: pointer; color: #0d6efd; text-decoration: underline; } .text-copy:hover { color: #1b6be4; } <html> <head> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css"> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/js/bootstrap.bundle.min.js"></script> </head> <body> <h2 class="text-copy" value="your copy text">your text</h2> <br> <h4>paste here</h4> <input type="text"> </body> </html>
使用这个函数:
function copy_input($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")
})
