记录一下前端H5的复制功能在ios端的兼容性问题

<divclassName="copy-btn"onClick={this.copyUrl}>复制链接</div>// 点击复制按钮copyUrl=async () => {
constpostData= {
expire: this.state.whichTagExpire,
tagId: this.state.whichTagIdSelected    }
constpath='/tag/getUrl';
// 获取异步数据constres=awaitHttp.post(path, postData);
// 复制数据copy(res.data);
  }

<divclassName="copy-btn"onClick={this.copyUrl}>复制链接</div>// 提前获取异步数据，并存储到state中asynccomponentDidMount() {
constpostData= {
expire: this.state.whichTagExpire,
tagId: this.state.whichTagIdSelected    }
constpath='/tag/getUrl';
constres=awaitHttp.post(path, postData);
this.setState({
url: res.data  })
  }
// 点击复制按钮，直接调用copy，复制urlcopyUrl= () => {
copy(this.state.url);
  }
