如何告诉Selenium在Chrome 75的打印弹出窗口中按“取消"? [英] How can I tell Selenium to press cancel on a print popup in Chrome 75?

问题描述

我一直在使用以下建议的解决方案: https://stackoverflow.com/a/41670021/4633408

I have been using the the suggested solution from : https://stackoverflow.com/a/41670021/4633408

自Chrome 71以来，它运行完美.

And it worked perfectly since Chrome 71.

executor.executeScript("document.querySelector(\"print-preview-app\").shadowRoot.querySelector(\"print-preview-header\").shadowRoot.querySelector(\"paper-button.cancel-button\").click();");

但是它不再起作用.

有人能找到一种方法来单击Chrome 75的打印预览中的取消"吗?

Has anyone figured out a way to click, "Cancel" in the print preview for Chrome 75?

我发现了异常，它只是说:

I caught the exception and it simply says:

 e:org.openqa.selenium.WebDriverException: unknown error: Cannot read property 'shadowRoot' of null

推荐答案

在版本75.0.3770.142(正式版本)(64位)上进行了测试.它们现在具有其他元素

Tested this on Version 75.0.3770.142 (Official Build) (64-bit) .They have additional element now

<print-preview-sidebar id="sidebar"></print-preview-sidebar>

用于在控制台中进行测试

For testing in console

document.querySelector("print-preview-app").shadowRoot.querySelector("print-preview-sidebar").shadowRoot.querySelector("print-preview-header").shadowRoot.querySelector("paper-button.cancel-button").click()

使用executor.executeScript

with executor.executeScript

executor.executeScript("document.querySelector(\"print-preview-app\").shadowRoot.querySelector(\"print-preview-sidebar\").shadowRoot.querySelector(\"print-preview-header\").shadowRoot.querySelector(\"paper-button.cancel-button\").click();")

编辑 ::对于版本 79.0.3945.88 (正式版本)(64位)

EDIT :: For Version 79.0.3945.88 (Official Build) (64-bit)

document.querySelector("print-preview-app").shadowRoot.querySelector("print-preview-sidebar").shadowRoot.querySelector("print-preview-button-strip").shadowRoot.querySelector("cr-button.cancel-button").click()
