复制当前url按钮-Javascript

Copy current url button - Javascript

本文关键字：按钮 -Javascript url 复制      更新时间：2023-09-26

好吧，这可能是简单的或完全错误的事情，但我正在尝试创建一个按钮来将当前URL复制到剪贴板，这就是我目前所拥有的，我对javascript不太熟悉，所以这是从几个来源混合而来的，希望最好。

<button onclick="CopyLink()">Click me</button>
<script>
function CopyLink() {
window.clipboardData.setData("Text", location.href);
}
</script>

任何帮助都将不胜感激！

使用这个答案中的函数copyTextToClipboard，您可以复制按钮上的链接，点击如下：

function copyTextToClipboard(text) {
  var textArea = document.createElement("textarea");
  //
  // *** This styling is an extra step which is likely not required. ***
  //
  // Why is it here? To ensure:
  // 1. the element is able to have focus and selection.
  // 2. if element was to flash render it has minimal visual impact.
  // 3. less flakyness with selection and copying which **might** occur if
  //    the textarea element is not visible.
  //
  // The likelihood is the element won't even render, not even a flash,
  // so some of these are just precautions. However in IE the element
  // is visible whilst the popup box asking the user for permission for
  // the web page to copy to the clipboard.
  //
  // Place in top-left corner of screen regardless of scroll position.
  textArea.style.position = 'fixed';
  textArea.style.top = 0;
  textArea.style.left = 0;
  // Ensure it has a small width and height. Setting to 1px / 1em
  // doesn't work as this gives a negative w/h on some browsers.
  textArea.style.width = '2em';
  textArea.style.height = '2em';
  // We don't need padding, reducing the size if it does flash render.
  textArea.style.padding = 0;
  // Clean up any borders.
  textArea.style.border = 'none';
  textArea.style.outline = 'none';
  textArea.style.boxShadow = 'none';
  // Avoid flash of white box if rendered for any reason.
  textArea.style.background = 'transparent';
  textArea.value = text;
  document.body.appendChild(textArea);
  textArea.select();
  try {
    var successful = document.execCommand('copy');
    var msg = successful ? 'successful' : 'unsuccessful';
    console.log('Copying text command was ' + msg);
  } catch (err) {
    console.log('Oops, unable to copy');
  }
  document.body.removeChild(textArea);
}
function CopyLink() {
  copyTextToClipboard(location.href);
}
<button onclick="CopyLink()">Click me</button>
