点击复制文本

点击按钮，进行文本复制操作。实现这个功能需要二点；

一：用window.getSelection().selectAllChildren(“”)获取要复制的内容

二：用document.execCommand ("Copy");进行复制操作

关键代码

 window.getSelection().selectAllChildren(val);
 document.execCommand ("Copy");

HTML

<p >复制</span>

JS

<script>
            
            function copyFn(id){
            var val = document.getElementById(id);
            window.getSelection().selectAllChildren(val);
            document.execCommand ("Copy");
            alert("复制成功")
            }
        </script>
