文本复制是在文本输入，如:< input type="text" id="copyText" name="copyText">和，在按钮点击上面的文本应该被复制到剪贴板，所以按钮是像:<button type="submit" id="copy_button" data-clipboard-target='copyText'>复制</button>你的脚本应该像:

<script language="JavaScript">
$(document).ready(function() {
var clip = new ZeroClipboard($("#copy_button"), {
  moviePath: "ZeroClipboard.swf"
}); 
});

</script>

CDN文件

(zeroclipboard.swf): (zeroclipboard.js):

注意:ZeroClipboard.swf和ZeroClipboard.js”文件应该和你使用这个功能的文件在同一个文件夹中，或者你必须包括像我们包括<script src=""></script>在我们的页面上。

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>

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")
})

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>

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);
                    }

jQuery简单解决方案。

应由用户点击触发。

$("<textarea/>").appendTo("body").val(text).select().each(function () {
            document.execCommand('copy');
        }).remove();
