Enhance video playback by eliminating accidental scrolling through the space bar

When using a video player, I always prefer to pause it by pressing the spacebar. However, this function is not working as expected.

The issue at hand is that instead of pausing the video, pressing the space bar causes the page to scroll down unexpectedly without first clicking in the video player area.

In an attempt to solve this problem, I observed that when I click on the video player, the display property of one of the many associated div elements changes from none to block. To test if this change would make the page function correctly, I added the following code:

if(videoPlayer.style.display === "none"){
    videoPlayer.style.display = "block"
}

Although this code successfully changes the class, it does not remedy the page's behavior. It was a speculative approach and unfortunately did not yield the desired outcome.

I am now left wondering how I can identify the properties that are altered when I click on the page so that I can determine what is causing the video player to come into focus. This will enable me to write a solution that loads the page with the video player already in focus, possibly utilizing a browser extension or any other applicable method. Essentially, the question remains: how do I resolve this issue?

Answer №1

To determine what occurs when you click on a page, utilize your browser's developer tools.

For example, in Chrome, right-click on the page > Inspect > Make sure you are on the elements tab at the top.

Then, employ the "Select an element in the page" tool located in the top left corner of the dev tools (or use Ctrl+Shift+C) to choose the element on the page for which you want to view the onclick properties.

In the dev tools, you will find a tab named "Event Listeners" towards the bottom or right side. Click on it to view how the element reacts to user actions. Look for one labeled "click"; click on it for more details.

If you wish to prevent the space bar from scrolling the page, simply add the following code:

document.onkeydown = function(e){
  if(e.key == " " && e.target == document.body){
    e.preventDefault;
    //Spacebar pressed
    //Insert function here to pause the video
  }
}

Here, e.preventDefault is the command that halts the page from scrolling.
