废话不多说，代码敏感，只上局部。

这个JS加密在NodeJs环境下运行会报错，window对象找不到，这个比拟好解决，间接var window = global;就行了，随后又报错，atob办法找不到。
由此能够剖析出，因为nodejs中没有window对象，只有global，而global中又没有atob办法。
解决办法
window内置的atob和btoa其实就是Base64的加密解密办法，咱们本人用js写一个Base64就行了，之前的文章中也有写过，代码能够在往期文章中找。
齐全解码后(局部代码)
function base64Success() { if (H5Url.indexOf('?') != -1) { H5Url += "&isQuickapp=1"; } else { H5Url += "?isQuickapp=1"; } webUrlBase64 = Base64.encode("{\"url\":\"" + H5Url + "\"}");}function getQueryVariable(url) { var searchStr = window.location.search.substring(1); var prmAry = searchStr.split('&'); for (var i = 0; i < prmAry.length; i++) { var prm = prmAry[i].split('='); if (prm[0] == url) { return prm[1]; } } return false;}结语
js解密就像剥洋葱，一层层的扒，扒到最初要么找到真像，要么啥都没了。
