Determine in vue whether the current page is embedded in the applet or in the WeChat browser

1. Use weixin-js-sdk

npm install weixin-js-sdk
//在当前页面引入
import wx from "weixin-js-sdk";

2. Add the following code where you need to judge

      var ua = window.navigator.userAgent.toLowerCase();
      let that = this;
      if (ua.match(/MicroMessenger/i) == "micromessenger") {
        //微信环境下
        wx.miniProgram.getEnv(function (res) {
          if (res.miniprogram) {
            // 小程序环境下逻辑
            console.og("小程序环境下")
          } else {
            //非小程序环境下逻辑
            console.log("非小程序环境下")
          }
        });
      }
