Vue3实现剪贴板功能

1.新增依赖

"vue-clipboard2": "^0.3.3"

2.main.js导入和使用依赖

import VueClipBoard from "vue-clipboard2";

createApp(App)
  .use(VueClipBoard)
  .mount("#app");

3.导入syncHandle和proxy

import { getCurrentInstance } from "vue";
import { syncHandle } from "@/utils/util.js";
const { proxy } = getCurrentInstance();

4.定义syncHandle函数

// util.js
export function syncHandle(func) {
  let timer = setTimeout(async () => {
    await func();
    clearTimeout(timer);
  }, 0);
}

5.实现剪贴板功能（兼容安卓和ios）

syncHandle(() => {
  proxy.$copyText(url).then(
    (success) => {
      Toast.success("下载链接已复制到剪贴板，请使用浏览器下载");
    },
    (err) => {
      Toast.fail("复制失败");
    }
  );
});

在项目中使用示例：

const getDownloadToken = () => {
  const toast = Toast.loading({
    duration: 0,
    forbidclick: true,
  });
  return new Promise((resolve, reject) => {
    TaskApi.getDownloadToken({ workId: sessionStorage.workId })
      .then((response) => {
        toast.close();
        const data = response.data;
        if (data.code === 200) {
          const token = data.data;
          let host = "";
          if (import.meta.env.MODE == "production")
            host = "https://" + window.location.host;
          const url = `${host}${
            import.meta.env.VITE_APP_BASE_API
          }/actkapwork/downloadWorkOrder?workId=${
            sessionStorage.workId
          }&token=${token}`;
          console.log(url);
          // proxy.$copyText(url).then(() => {
          //   Toast.success("下载链接已复制到剪贴板，请使用浏览器下载");
          // });
          syncHandle(() => {
            proxy.$copyText(url).then(
              (success) => {
                Toast.success("下载链接已复制到剪贴板，请使用浏览器下载");
              },
              (err) => {
                Toast.fail("复制失败");
              }
            );
          });
        } else {
          Toast.fail(data.message);
        }
      })
      .catch((error) => {
        if (error.message !== "") {
          Toast.fail(error.message);
        }
      });
  });
};
