For QAs to roll out robust and bug-free web applications, they need to ensure that web pages are thoroughly tested. They especially need to verify that every single UI element is functioning as expected. To do so quickly, they use test automation frameworks like Selenium.
A Scroll is a JavaScript method. The JavaScriptExecutor provides an interface that enables QAs to run JavaScript methods from Selenium scripts. Hence, to scroll up or down with Selenium, a JavaScriptExecutor is a must.

(Sorry for my bad english, it's not my native language)Hello, it's been many months that I have a problem with automatic scrolling FirefoxMaintain pressure on the mouse wheel can slide in all directions of the web page, very useful for long pages and also for very high resolution pictures.
Off for several release (from 40.0.0 I think but not certainty), scrolling stops and / or is extremely slow and choppy until the page is not fully charged. This is all the more painful if we wait for loading a heavy image on a slow site.
I tested with the Firefox Safe Mode and it changes nothing.Disable graphics acceleration nor solves this defect.Test a new blank profile ...Remove and reinstall Firefox ...Namely I met no automatic scrolling problem on Internet Explorer or Chrome.
I don't know what causes this. I've disabled the flash player, and that solved the problem for a bit, but it's now scrolling up and down without my control. It's irritating as I can't read the pages for the scrolling.
I haven't turned on the scroll wheel. I never touch it. I don't move my mouse at all when the page starts just randomly scrolling up and down. I'm not even touching it when this happens. It's almost as if there's someone else controlling my computer from another computer, like those connected to a common server in a workplace.
I can't start Firefox with my shift key down. It won't start up like that. The auto scrolling only occurs after I've been online for a time. As for the scrolling with the cursor key in the advanced options, it's never been checked. I don't know why it does that. It doesn't just go one direction, either. It'll go up and down, almost as if someone is searching for something.
Browsers such as Chrome have a built-in preset to remember where you were on the page, after refreshing. Just a window.onload doesn't work because your browser will automatically scroll you back to where you were before refreshing, AFTER you call a line such as:
Most web pages these days are so chock-full of content that it is impossible to make everything fit the dimensions of your computer screen. Unless, of course, you reduce the font, in which case good luck squinting your way through the text. We scroll down to reveal more content and up to return to previous lines. We accomplish this by pressing the up and down directional bottom arrows on the keyboard. Those using desktop PCs can also use the mouse wheel to accomplish the same thing while laptop users can just plug in a USB mouse. Another method is to place the cursor on the narrow scroll bar at the right border of the page, then hold LMB as you move your hands up and down on your laptop trackpad.
With autoscroll, your web page becomes automated as it slowly scrolls up according to a set speed, allowing you to read at leisure without lifting a finger. Even though it is not natively present in Windows and Firefox, your computer still provides the next best thing in the shape of middle-scrolling with a mouse or three-finger clicking with your trackpad. There is also the Page Up and Page Down keys that allow you to jump the height of one screen up or down.
Naturally, none of these options is as satisfactory as true auto scrolling. Which is why developers in their wisdom have created browser extensions and other tools that trigger the autoscroll feature. Some of these tools can be used in any browser, be it Chrome, Firefox or Opera; some only work in a specific browser. We have compiled a list of tools that, when enabled, will allow pages in Firefox to automatically scroll up or down.
This method takes advantage of the code injection technique to force autoscroll. By pressing F12 (your computer might require a different function key), you open the page console for the webpage. Then you must copy and paste the following code into the console:
A bookmarklet is a small program stored in your web browser that brings added functionality to the page, and that is exactly what HandsFred Bookmarklet is. This software is saved in Firefox and enables you to autoscroll the current page. It is relatively straightforward to use. Just place the program on your bookmark bar and click on it whenever you want to use autoscroll.
The more times you click on HandsFread Bookmarklet, the faster the scrolling becomes. Sadly, there is no way to reverse the process. It is basically a start, speed and stop program. You press F5 or refresh the page to stop auto scrolling.
Autoscroll by developer igor86 is, as the name pretty much implies, an autoscroll add-on. The download page describes it as a toggle button that can scroll long web pages, adding dynamic content. Autoscroll comes with a preference page where you can set the scroll interval. It also comes with the end detection timeout option which allows you to stipulate the maximum time of user inactivity after which the page stops scrolling.
FoxScroller brings two-directional scrolling to Firefox. After installing, one click will enable autoscroll and the page will continue scrolling down until the add-on button is clicked again. Right-clicking the button brings up options to scroll up or down.
This Firefox extension comes with a settings page (accessed by right-clicking the button and selecting Options). In the Options menu you can adjust scrolling speed (in pixels per second), set end-of-page action, enable continuous scrolling after switching pages or reloading the current one. You can also set new pages to start scrolling automatically once they have finished loading. Best of all, you can set hotkeys for the more important actions.
This add-on is similar to FoxScroller in offering two-way scrolling. It also offers users the option to change scrolling speed in lines per minute. The default is 50. If default scrolling settings are retained, the page will start scrolling in reverse once it reaches the bottom.
This software by hizakazu is a simple scroller that enables autoscroll and nothing else. The automatic scrolling process is initiated by clicking the add-on button and stopped by clicking it again. Switching tabs will also kill automatic scrolling.
I am currently using selenium webdriver to parse through facebook user friends page and extract all ids from the AJAX script. But I need to scroll down to get all the friends. How can I scroll down in Selenium. I am using python.
Here's an example selenium code snippet that you could use for this type of purpose. It goes to the url for youtube search results on 'Enumerate python tutorial' and scrolls down until it finds the video with the title: 'Enumerate python tutorial(2020).'
You can do that with code, the trick is to inject Javascript code to be webpage. After you load a webpage, scroll down the page by injecting javascript.You can scroll down a specific amount or all the way to the bottom.
I am using Firefox (Developer Edition) as my primary debugging environment for web-development. Is there some way to make the Web Console automatically scroll to keep up with new output as it is logged?
