vue移动端全屏返回功能的实现

话不多说，直接上代码：

npm install vue-awesome-mui
import Mui from 'vue-awesome-mui';
Vue.use(Mui);
router.beforeEach((to, from, next) => {
  var quit = false
  mui.back = function () { 
    if (!quit) {
      // home和line为首页一级路由name值
      if (to.name == 'home' || to.name == 'line') {
        mui.toast("再按一次退出应用")
        quit = true
        setTimeout(function () {
          quit = false
        }, 2000)
      } else {
        if (to.matched[0].instances.default.showmask) {
          to.matched[0].instances.default.showmask = false
        } else {
          history.go(-1); // 返回上一页
        }
      }
    } else {
      plus.runtime.quit(); //退出app
    }
  }
  next()
})
