Selenium/java:如何获得总页面长度 [英] Selenium / java: how to get get total page length

问题描述

使用 Selenium Java 绑定.

Using Selenium Java bindings.

我正在尝试编写一个简短的模块来获取浏览器页面的完整屏幕截图(我知道 AShot 存在但它没有得到维护并且对我来说有一些问题).

I'm trying to write a short module that will take a full screenshot of a browser page (I know AShot exists but it is not maintained and has some issues for me).

作为其中的一部分，我想知道我正在处理的整页长度是多少，以便我可以计算我需要拍摄的照片数量，以及底部的任何余数.有很多示例展示了如何滚动到页面底部(例如 这个问题)，但我想知道是否有办法让 JavascriptExecutor 返回页面长度的值，以便我可以使用它在我的脚本中?

As part of this I would like to know what the full page length is that I'm dealing with so I can calculate the number of shots I need to take, and any remainder at the bottom. There are many examples out there showing how to scroll to the bottom of a page (e.g. this question), but I am wondering if there is a way to make the JavascriptExecutor return the value of the page length so I can use it in my script?

推荐答案

您需要 scrollHeight

JavascriptExecutor js = (JavascriptExecutor) driver;         
js.executeScript("return document.documentElement.scrollHeight");

在进一步寻找更强大的解决方案之后，这个 Javascript 代码(我从同一个 网站) 应该提供更好的结果:

After looking further for a more robust solution, this Javascript-code (which I took from the same website) should provide a better result:

let scrollHeight = Math.max(
  document.body.scrollHeight, document.documentElement.scrollHeight,
  document.body.offsetHeight, document.documentElement.offsetHeight,
  document.body.clientHeight, document.documentElement.clientHeight
);

return scrollHeight;
