将h1元素的内容复制到剪贴板？

Question

所以，我做了一个翻译，但并不是很好。 但无论如何，它正在工作，我想尝试添加一些可以复制结果的东西。 有没有办法做到这一点？ 以下是我的代码：提前致谢！ 我知道有一种方法可以用输入来做到这一点，但我不确定它是否可以用标题来完成。

 var myText; var letters; var letterslength; var result; var firstletter; var newresult; var vowels = ['a', "e", "i", "o", "u"] function GO(){ myText=document.getElementById('inputBox').value; letters=myText.split(""); //console.log(letters); letterslength=letters.length; if(vowels.includes(letters[0])){ letters = letters.join(''); result=letters+'yay'; document.getElementById('changetext').innerHTML=result; history.push(result); } else{ firstletter=letters[0] letters.shift(); letters = letters.join(''); result=letters+firstletter; newresult=result+"ay"; document.getElementById('changetext').innerHTML=newresult; } } function copy(){ var copyText = document.getElementById("changetext"); copyText.select(); document.execCommand("copy"); document.getElementById('copyer').innerHTML="Copied"+copyText.value; setTimeout(revert, 3000); } function revert(){ document.getElementById('copyer').innerHTML= 'Copy To Clipboard!'; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <DOCTYPE html> <html> <head> <title>Pig Latin Translator!</title> <link href="style.css" rel="stylesheet"> </head> <body> <br> <h1>Pig Latin Translator</h1> <p>You are on the island of Pig Land. You must learn the difficult language of Pig Latin. Lucky for you, you can use this website to help you survive. One word at a time please.</p> <br> <br> <input id="inputBox" placeholder="Type your English Here..."> <br> <br> <br> <button onclick="GO();">Translate!</button> <br> <h1 id="changetext">...and the text will appear here!</h1> <button style="width: 100px; display: inline;" id="copyer" onclick="copy();">Copy To Clipboard!</button> <br> <br> </body> </html>

Answer 1

这是一个从元素复制文本的函数：

function copyElementText(id) {
    var text = document.getElementById(id).innerText;
    var elem = document.createElement("textarea");
    document.body.appendChild(dummy);
    dummy.value = text;
    dummy.select();
    document.execCommand("copy");
    document.body.removeChild(dummy);
}

只需在你的标题上调用它：

copyElementText("changeText");

它会工作！

演示片段：

 function copyElementText(id) { var text = document.getElementById(id).innerText; var elem = document.createElement("textarea"); document.body.appendChild(elem); elem.value = text; elem.select(); document.execCommand("copy"); document.body.removeChild(elem); }

 <button onclick="copyElementText('heading')">Click Me!</button> <h1 id="heading">Text to be Copied</h1>

Answer 2

要复制文本，您可以使用：

var temp = document.createElement("textarea");
document.body.appendChild(temp);
temp.value= copyText.innerText
temp.select();
document.execCommand("copy");

替换： document.getElementById('copyer').innerHTML="Copied"+copyText.value; 到document.getElementById('copyer').innerText="Copied "+temp.value;

temp.value是要复制到剪贴板的临时数据。 您正在使用的临时数据不要忘记删除临时数据完成后 ： document.body.removeChild(temp);

检查以下小提琴：

 var myText; var letters; var letterslength; var result; var firstletter; var newresult; var vowels = ['a', "e", "i", "o", "u"] function GO(){ myText=document.getElementById('inputBox').value; letters=myText.split(""); //console.log(letters); letterslength=letters.length; if(vowels.includes(letters[0])){ letters = letters.join(''); result=letters+'yay'; document.getElementById('changetext').innerHTML=result; history.push(result); } else{ firstletter=letters[0] letters.shift(); letters = letters.join(''); result=letters+firstletter; newresult=result+"ay"; document.getElementById('changetext').innerHTML=newresult; } } function copy(){ var copyText = document.getElementById("changetext"); var temp = document.createElement("textarea"); document.body.appendChild(temp); temp.value= copyText.innerText temp.select(); document.execCommand("copy"); document.getElementById('copyer').innerText="Copied "+temp.value; document.body.removeChild(temp); setTimeout(revert, 3000); } function revert(){ document.getElementById('copyer').innerHTML= 'Copy To Clipboard!'; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <DOCTYPE html> <html> <head> <title>Pig Latin Translator!</title> <link href="style.css" rel="stylesheet"> </head> <body> <br> <h1>Pig Latin Translator</h1> <p>You are on the island of Pig Land. You must learn the difficult language of Pig Latin. Lucky for you, you can use this website to help you survive. One word at a time please.</p> <br> <br> <input id="inputBox" placeholder="Type your English Here..."> <br> <br> <br> <button onclick="GO();">Translate!</button> <br> <h1 id="changetext">...and the text will appear here!</h1> <button style="width: 100px; display: inline;" id="copyer" onclick="copy()">Copy To Clipboard!</button> <br> <br> </body> </html>
