这是Chase Seibert答案的扩展,其优点是它适用于IMAGE和TABLE元素,而不仅仅是Internet Explorer 9上的DIV。
if (document.createRange) {
// Internet Explorer 9 and modern browsers
var r = document.createRange();
r.setStartBefore(to_copy);
r.setEndAfter(to_copy);
r.selectNode(to_copy);
var sel = window.getSelection();
sel.addRange(r);
document.execCommand('Copy'); // Does nothing on Firefox
} else {
// Internet Explorer 8 and earlier. This stuff won't work
// on Internet Explorer 9.
// (unless forced into a backward compatibility mode,
// or selecting plain divs, not img or table).
var r = document.body.createTextRange();
r.moveToElementText(to_copy);
r.select()
r.execCommand('Copy');
}

JavaScript/TypeScript中最简单的方法是使用此命令
navigator.clipboard.writeText(textExample);
只需在textExample中传递要复制到剪贴板的值
从网页读取和修改剪贴板会引发安全和隐私问题。然而,在Internet Explorer中,可以这样做。我找到了以下示例片段:
<script type=“text/javascript”>函数select_all(obj){var text_val=评估(对象);text_val.focus();text_val.select();r=text_val.createTextRange();if(!r.execCommand)return;//特征检测r.execCommand('copy');}</script><输入值=“http://www.sajithmr.com"onclick=“select_all(this)”name=“url”type=“text”/>
其他方法将纯文本复制到剪贴板。要复制HTML(即,可以将结果粘贴到所见即所得编辑器中),只能在Internet Explorer中执行以下操作。这与其他方法有根本不同,因为浏览器实际上可以直观地选择内容。
// Create an editable DIV and append the HTML content you want copied
var editableDiv = document.createElement("div");
with (editableDiv) {
contentEditable = true;
}
editableDiv.appendChild(someContentElement);
// Select the editable content and copy it to the clipboard
var r = document.body.createTextRange();
r.moveToElementText(editableDiv);
r.select();
r.execCommand("Copy");
// Deselect, so the browser doesn't leave the element visibly selected
r.moveToElementText(someHiddenDiv);
r.select();

ZeroClipboard是我找到的最好的跨浏览器解决方案:
<div id="copy" data-clipboard-text="Copy Me!">Click to copy</div>
<script src="ZeroClipboard.js"></script>
<script>
var clip = new ZeroClipboard( document.getElementById('copy') );
</script>
如果您需要iOS的非Flash支持,只需添加一个回退:
clip.on( 'noflash', function ( client, args ) {
$("#copy").click(function(){
var txt = $(this).attr('data-clipboard-text');
prompt ("Copy link, then click OK.", txt);
});
});
