Selenium - 完成ajax加载自动滚动到页面底部 [英] Selenium - complete ajax loading autoscroll to bottom of page

问题描述

我有一个网页，当您滚动到底部时，它会通过ajax加载更多结果。在完成之前，您可以对此进行多次迭代。有点像facebook那样。

I have a webpage where when you scroll to the bottom it then loads more results via ajax. You can do several iterations of this before it completes. Bit like what facebook does.

我正在尝试编写一个selenium脚本，一直到页面的末尾，直到它完成。

I am trying to write a selenium script to keep going to the end of the page until it completes.

像这样的一半完成了它...我只是不知道如何确定页面是否在底部 - 所以我可以把它放在一个循环中某种？

Something like this sort of half completes it.. I just don't know how to determine if page is at the bottom - so i can put it inside a loop of some sort?

我的尝试

    By selBy = By.tagName("body");

    driver.findElement(selBy).sendKeys(Keys.PAGE_DOWN);
    System.out.println("Sleeping... wleepy");

    Thread.sleep(5000);
    driver.findElement(selBy).sendKeys(Keys.PAGE_DOWN);

    System.out.println("Sleeping... wleepy1");
    Thread.sleep(3000);

    //etc...

可能看起来像这样？

hasScroll（）不是一个真正的方法。我把它放在那里展示我想要实现的目标

Could Look like this?
hasScroll() isnt a real method. I put that there to demonstrate what im trying to achieve

   while (driver.findElement(By.tagName("body")).hasScroll()) {
        driver.findElement(selBy).sendKeys(Keys.PAGE_DOWN);
        System.out.println("Sleeping... wleepy");
        Thread.sleep(2000);
   }

推荐答案

尝试这种方法：

//Get total height
By selBy = By.tagName("body"); 
int initialHeight = driver.findElement(selBy).getSize().getHeight();
int currentHeight = 0;

while(initialHeight != currentHeight){
        initialHeight = driver.findElement(selBy).getSize().getHeight();

        //Scroll to bottom
        ((JavascriptExecutor) driver).executeScript("scroll(0," + initialHeight + ");");

        System.out.println("Sleeping... wleepy");
        Thread.sleep(2000);

        currentHeight = driver.findElement(selBy).getSize().getHeight();
}
