How to implement copy function in vuejs

##1, first create a copyComm.js file

const vCopy = { // 名字爱取啥取啥 /* bind 钩子函数,第一次绑定时调用,可以在这里做初始化设置 el: 作用的 dom 对象 value: 传给指令的值,也就是我们要 copy 的值 */ bind(el, { value }) { el.$value = value; // 用一个全局属性来存传进来的值,因为这个值在别的钩子函数里还会用到 el.handler = () => { if (!el.$value) { // 值为空的时候,给出提示,我这里的提示是用的 ant-design-vue 的提示,你们随意 console.log('无复制内容'); return; } // 动态创建 textarea 标签 const textarea = document.createElement('textarea'); // 将该 textarea 设为 readonly 防止 iOS 下自动唤起键盘,同时将 textarea 移出可视区域 textarea.readOnly = 'readonly'; textarea.style.position = 'absolute'; textarea.style.left = '-9999px'; // 将要 copy 的值赋给 textarea 标签的 value 属性 textarea.value = el.$value; // 将 textarea 插入到 body 中 document.body.appendChild(textarea); // 选中值并复制 textarea.select(); textarea.setSelectionRange(0, textarea.value.length); const result = document.execCommand('Copy'); if (result) { console.log('复制成功'); } document.body.removeChild(textarea); }; // 绑定点击事件,就是所谓的一键 copy 啦 el.addEventListener('click', el.handler); }, // 当传进来的值更新的时候触发 componentUpdated(el, { value }) { el.$value = value; }, // 指令与元素解绑的时候,移除事件绑定 unbind(el) { el.removeEventListener('click', el.handler); }, }; export default vCopy;
