如何禁用“重新加载网站"?您所做的更改可能不会保存" Chrome中的(python)硒测试的弹出窗口? [英] How to disable a "Reload site? Changes you made may not be saved" popup for (python) selenium tests in chrome?

问题描述

我在chrome浏览器上运行自动化(python)硒测试，有时重新加载页面时，屏幕上会出现一个弹出窗口:

I am running automated (python) selenium tests on a chrome browser, and sometimes when a page is reloaded a popup appears on the screeen:

是否可以通过这种方式配置Chrome硒浏览器，使该弹出窗口不出现?如果是这样，该怎么做?还是有其他方法可以抑制此弹出窗口?还是接受它?

Is it possible to configure the chrome selenium browser in such a way, that this popup does not appear? If so, how to do that? Or are there other ways to supress this popup? Or to accept it?

推荐答案

此弹出窗口，其文本为重新加载网站?您所做的更改可能不会保存，这是

This popup with text as Reload site? Changes you made may not be saved is the implementation of onbeforeunload property of WindowEventHandlers

的 onbeforeunload 属性href ="https://developer.mozilla.org/zh-CN/docs/Web/API/WindowEventHandlers" rel ="nofollow noreferrer"> WindowEventHandlers mixin是卸载其资源时，会触发这些事件.此时，文档仍然可见，事件仍可取消.

The onbeforeunload property of the WindowEventHandlers mixin is the EventHandler for processing beforeunload events. These events fire when a window is about to unload its resources. At this point, the document is still visible and the event is still cancelable.
