无法在Chrome 77中收听"popstate"事件? [英] Can't listen 'popstate' event in Chrome 77?

问题描述

需要在Chrome 77中监听返回按钮".为此，我知道使用"popstate"事件监听器. 我试过了:

Need to listen 'Back button' in Chrome 77. I know that for this using 'popstate' event listenter. I tried:

window.onpopstate = function (event) {
    console.log("location: " + document.location + ", state: " + JSON.stringify(event.state));
};

window.addEventListener('popstate', (event) => {
    console.log("location: " + document.location + ", state: " + JSON.stringify(event.state));
});

什么都没有.也尝试过调试... 如何调查此事件及其发生的原因(以前曾进行过工作)?

Nothing working. Tried also with debugging... How to investigate this event and why it's happened (worked before)?

推荐答案

根据我的上次经验:

popstate事件仅在页面上存在用户交互时有效.

popstate event only works when there is an user interaction on the page.

例如:

单击屏幕上的任意位置，然后单击返回"按钮.您将被popstate解雇.发出警报以轻松感受到它.

click anywhere on the screen then hit back button. You will get popstate fired . Put an alert to feel it easily.
