复制到剪贴板按钮

标签: javascript html sharepoint

我想创建“复制到剪贴板”按钮来处理我们的sharepoint。它们应放在几个不同的地方,我需要复制的是来自页面特定字段的一些文本(例如电子邮件列表)。

我知道,我可以选择文本并复制它,但我们经常这样做,所以有一个自动将文本复制到剪贴板的按钮将非常有用。

我确实设法在脚本编辑器中创建一个,我在下面粘贴了整个代码(我在互联网上找到)

<!DOCTYPE html>
<html>
<head>

<script type='text/javascript'>//<![CDATA[
window.onload=function(){
document.getElementById("copyButton").addEventListener("click", function() {
    copyToClipboardMsg(document.getElementById("copyTarget"), "msg");
});

document.getElementById("copyButton2").addEventListener("click", function() {
    copyToClipboardMsg(document.getElementById("copyTarget2"), "msg");
});

document.getElementById("pasteTarget").addEventListener("mousedown", function() {
    this.value = "";
});


function copyToClipboardMsg(elem, msgElem) {
      var succeed = copyToClipboard(elem);
    var msg;
    if (!succeed) {
        msg = "Copy not supported or blocked.  Press Ctrl+c to copy."
    } else {
        msg = "Text copied to the clipboard."
    }
    if (typeof msgElem === "string") {
        msgElem = document.getElementById(msgElem);
    }
    msgElem.innerHTML = msg;
    setTimeout(function() {
        msgElem.innerHTML = "";
    }, 2000);
}

function copyToClipboard(elem) {
      // create hidden text element, if it doesn't already exist
    var targetId = "_hiddenCopyText_";
    var isInput = elem.tagName === "INPUT" || elem.tagName === "TEXTAREA";
    var origSelectionStart, origSelectionEnd;
    if (isInput) {
        // can just use the original source element for the selection and copy
        target = elem;
        origSelectionStart = elem.selectionStart;
        origSelectionEnd = elem.selectionEnd;
    } else {
        // must use a temporary form element for the selection and copy
        target = document.getElementById(targetId);
        if (!target) {
            var target = document.createElement("textarea");
            target.style.position = "absolute";
            target.style.left = "-9999px";
            target.style.top = "0";
            target.id = targetId;
            document.body.appendChild(target);
        }
        target.textContent = elem.textContent;
    }
    // select the content
    var currentFocus = document.activeElement;
    target.focus();
    target.setSelectionRange(0, target.value.length);

    // copy the selection
    var succeed;
    try {
          succeed = document.execCommand("copy");
    } catch(e) {
        succeed = false;
    }
    // restore original focus
    if (currentFocus && typeof currentFocus.focus === "function") {
        currentFocus.focus();
    }

    if (isInput) {
        // restore prior selection
        elem.setSelectionRange(origSelectionStart, origSelectionEnd);
    } else {
        // clear temporary content
        target.textContent = "";
    }
    return succeed;
}


}//]]> 

</script>


</head>

<body>
  <input id="copyTarget" value="Some initial text"> <button id="copyButton">Copy</button><br><br>
<span id="copyTarget2">Some Other Text</span> <button id="copyButton2">Copy</button><br><br>
<input id="pasteTarget"> Click in this Field and hit Ctrl+V to see what is on clipboard<br><br>
<span id="msg"></span><br>



</body>

</html>

但我们遇到的主要问题是: 1)每次点击“复制”按钮,它都会重新加载页面 2)当我们考虑更新我们的文件时,它不是非常优雅和友好

我会非常感谢您对我的任何暗示,以及如何使其更好地运作。
