使用場景：小城跳轉(zhuǎn)到H5頁面寿桨，由于uniapp官網(wǎng)提供的uni.setClipboardData?不支持H5甘邀，但是在微信開發(fā)者工具上面是好用的练俐，而打包在手機上無效念秧。

1.嘗試方式一：

嘗試在網(wǎng)上搜索找了很多種方案激蹲，但都是無效的。如下方案看上去很絲滑的解決了問題叁温，但是在手機上回一直走 不支持復(fù)制那里，果斷放棄核畴∠サ可能是有的用戶好用吧，可能是場景不同谤草，這個方法沒有解決我的問題跟束，于是繼續(xù)探索。

2.嘗試方法二：

解決 報錯? ? ? [system] APIsetClipboardDatais not yet implemented

復(fù)制以下代碼 新建文件命名為 clipboard.js

然后 引用過來

import clipboardfrom "./xx/clipboard.js"

就可以直接使用了丑孩，使用的時候 會走如上的js方法冀宴，最后還是無效∥卵В可能對于某些場景會有效略贮，不然網(wǎng)上不會有這么多貼出這個方案的。

3.嘗試方式三（最終解決）

npm install clipboard --save? //項目中安裝clipboard

import Clipboard from 'clipboard';

然后頁面當中引用
import { handleClipboard? } from "../components/clipboard.js";

然后使用

// #ifdef H5 handleClipboard(re.data, () => { uni.showToast({ title: '已復(fù)制', duration: 2000, icon: 'none' }); this.$u.route({ url: 'pages/video/pages/downWay?images=' + this.images }) }, () => { uni.showToast({ title: ' 暫不支持 ', duration: 2000, icon: 'none' }); }) // #endif

最終反復(fù)測試好用Ｕ提Ｌ友印！轧拄！? 要根據(jù)自己的實際情況來使用揽祥，不能一味地照搬，我開始是用這種方式的時候 也是無效檩电，經(jīng)過無數(shù)次的改進最終國通過拄丰。
