将已有内容复制到剪切板

先在网页中插入input框并隐藏

<input type="button" hidden value="点击复制代码" /> <button @click="goOpen" type="primary">复制</button>

再在写入点击方法，点击后即可复制成功

public goOpen(): void { //var Url = location.href //获取网页URL var Url = '123213123' var oInput = document.createElement('input') oInput.value = Url document.body.appendChild(oInput) oInput.select() // 选择对象 document.execCommand('Copy') alert('复制成功') }
