推荐答案

根据规格存储界面发出 存储事件它影响的全局对象。

According to specs Storage interface emits storage event on global objects which it affects.

所以在你的情况下你可以只添加处理程序

So in your case you may just add handler

window.addEventListener("storage", function () {
    // do your checks to detect
    // changes in "e1", "e2" & "e3" here
}, false);

甚至不需要 jQuery 。
