vue中添加百度统计代码

var _hmt = _hmt || [];
window._hmt = _hmt; // 必须把_hmt挂载到window下，否则找不到
 (function () {
       var hm = document.createElement("script");
       hm.src = "https://hm.baidu.com/hm.js?"+ 百度站点id;
       var s = document.getElementsByTagName("script")[0];
       s.parentNode.insertBefore(hm, s);
  })();

router.beforeEach((to, from, next) => {
    if (_hmt) {
        if (to.path) {
            _hmt.push([‘_trackPageview‘, ‘/#‘ + to.fullPath]);
        }
    }
    next();
});
