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。

这是复制内容的最简单方法

 <div id="content"> Lorepm ispum </div>
 <button class="copy" title="content">Copy Sorce</button>

function SelectContent(element) {
                        var doc = document
                            , text = doc.getElementById(element)
                            , range, selection
                        ;    
                        if (doc.body.createTextRange) {
                            range = document.body.createTextRange();
                            range.moveToElementText(text);
                            range.select();
                        } else if (window.getSelection) {
                            selection = window.getSelection();        
                            range = document.createRange();
                            range.selectNodeContents(text);
                            selection.removeAllRanges();
                            selection.addRange(range);

                        }
                         document.execCommand('Copy');
                    }
                    $(".copy").click(function(){

                         SelectContent( $(this).attr('title'));
                    });

纯JS,没有内联onclick,配对类“内容-复制按钮”。如果你有很多元素,会更舒服)

(function(){ /* Creating textarea only once, but not each time */ let area = document.createElement('textarea'); document.body.appendChild( area ); area.style.display = "none"; let content = document.querySelectorAll('.js-content'); let copy = document.querySelectorAll('.js-copy'); for( let i = 0; i < copy.length; i++ ){ copy[i].addEventListener('click', function(){ area.style.display = "block"; /* because the classes are paired, we can use the [i] index from the clicked button, to get the required text block */ area.value = content[i].innerText; area.select(); document.execCommand('copy'); area.style.display = "none"; /* decorative part */ this.innerHTML = 'Cop<span style="color: red;">ied</span>'; /* arrow function doesn't modify 'this', here it's still the clicked button */ setTimeout( () => this.innerHTML = "Copy", 2000 ); }); } })(); hr { margin: 15px 0; border: none; } <span class="js-content">1111</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">2222</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">3333</span> <button class="js-copy">Copy</button>

旧的浏览器支持:

(function(){ var area = document.createElement('textarea'); document.body.appendChild( area ); area.style.display = "none"; var content = document.querySelectorAll('.js-content'); var copy = document.querySelectorAll('.js-copy'); for( var i = 0; i < copy.length; i++ ){ copyOnClick(i); } function copyOnClick(i){ copy[i].addEventListener('click', function(){ area.style.display = "block"; area.value = content[i].innerText; area.select(); document.execCommand('copy'); area.style.display = "none"; var t = this; t.innerHTML = 'Cop<span style="color: red;">ied</span>'; setTimeout( function(){ t.innerHTML = "Copy" }, 2000 ); }); } })(); hr { margin: 15px 0; border: none; } <span class="js-content">1111</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">2222</span> <button class="js-copy">Copy</button> <hr> <span class="js-content">3333</span> <button class="js-copy">Copy</button>

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。

function copyToClipboard(element) {
    var $temp = $("<input>");
    $("body").append($temp);
    $temp.val($('span[id='+element+']').text()).select();
    document.execCommand("copy");
    $temp.remove();
}

js是一个很好的实用工具,它允许在不使用Flash的情况下将文本或HTML数据复制到剪贴板。它很容易使用;只需要包含.js并使用如下代码:

<button id='markup-copy'>Copy Button</button>

<script>
    document.getElementById('markup-copy').addEventListener('click', function() {
        clipboard.copy({
            'text/plain': 'Markup text. Paste me into a rich text editor.',
            'text/html': '<i>here</i> is some <b>rich text</b>'
        }).then(
            function(){console.log('success'); },
            function(err){console.log('failure', err);
        });
    });
</script>

clipboard.js也在GitHub上。
