kandi X-RAY | isInViewport Summary
An ultra-light jQuery plugin that tells you if the element is in the viewport, but with a twist. Did you say [demo] (inclusive of tests)?. For a more performant alternative, please take a look at [observe-element-in-viewport] which uses the new IntersectionObserver API. Please keep in mind that you might have to ship a [polyfill] for IntersectionObserver depending on the browsers you support. Note: If you need this in a React application, please use the [use-is-in-viewport hook] When used as a selector it returns all the elements that match. Since it returns the element(s) it can thus be chained with other jQuery methods. It can also be used with jquery’s .is.

QUESTION
What I am aiming to achieve is something that looks like this. you can see it in action on this URL, if you scroll a bit.
I was thinking at first to try using inViewport, and every time a heading or a paragraph is in viewport to show one image and hide the previous. but my problem is that the elements are in viewport in conjunction
This is the initial code I was using:
ANSWER
Answered 2022-Feb-07 at 23:31It should be quite simple by using the IntersectionObserver API to watch for your elements intersecting the viewport, or any other (Options root) ancestor.
To detect an element reaches the viewport vertical center can be done by passing the Option rootMargin where the bottom and top values are set at -50%, with an Option threshold set to 0 (as soon as one pixel enters that intersecting area)

QUESTION
Context: I have a subtitle "About me" that animates with the library animejs as soon as it comes into view in the screen (every time). You can find the animation here, i got it from Tobia's Moving Letters.
The problem: As I scroll down to the subtitle, I'm able to see it right before the animation plays. So in other words: I scroll down, I read the subtitle "About me" and then it disappears just to have the letter pop in one by one.
This isn't want, I am looking for a way to have the initial text "About me" hidden and then have each animated letter appear
I made a snippet with the subtitle under some dummy text so it can be scrolled into.
...ANSWER
Answered 2021-Dec-11 at 23:20So there's most likely a better solution than this out there to be honest. But that's a quick way I found to get near to what you want. The problem with this is, that if it's in the viewport from the beginning and no scrolling occurs it will never show. You'll have to handle that.Using an IntersectionObserver would probably be a better fit for your case here.

QUESTION
I'm making a webpage that has two different navbars... Lets say I named them navbar1 and navbar2.. soo the navbar1 is being used on the home page of the web site and navbar2 on all other sub pages... I have written a pure Javascript function that checks if the navbar1 exists in DOM and if it does then it does something... if navbar1 doesent exist in DOM it should ignore that part of code and move forward with the rest...
so now I have this issue that I spent several hours now trying to resolve... and I just can figure it out... When I go to the home page the code works... everything that should happen to navbar1 happens... but if I go to a subpage that doesn't use navbar1 I get this error in the console: "Cannot read properties of null (reading 'getBoundingClientRect')"
I would apreciate some help... and if it matters I don't have much experience with javascript so :)
So here's my JS code...

QUESTION
My goal is to complete a dynamic single landing page using JavaScript. HTML and CSS files were already provided and I managed to build an unordered list by manipulating the DOM.
The thing that got me stuck is: When clicking an item from the navigation menu, the link should scroll to the appropriate section. I cannot get this to work :/
Below is the JS code so far.
...ANSWER
Answered 2021-Oct-21 at 09:47You can use anchor to do this. This will make your life easier than trying to do this in js.
To use it, you just have to set an id to a node. Like
href of your link to #myFirstId.
If you want your scroll to not be instant, you can add the scroll-behavior: smooth to the scrollable element.

QUESTION
I'm using a jQuery code for showing animated stats for my web page.
The number animates successfully, but a few seconds after reaching its max value it starts counting down back to 1! How can I fix this?
...ANSWER
Answered 2021-Jun-21 at 08:08The issue is because your logic to prevent the animation being triggered multiple times on scroll isn't quite correct, and is in fact queuing the event handler multiple times.
Your isInViewport() function needs to be called on each individual element, not the collection. As such the if condition should be inside the $.each().
In addition you're using a single variable to manage state of all of the animatable elements. You can manage their state individually by using a data attribute on them individually.
With that said, try this:

I am using isinViewport from https://github.com/zeusdeux/isInViewport to play/pause videos when in/out of view. But sometimes I don't want them to autoplay (for videos that are not muted and with controls).
Hence I am checking for if is in viewport & with property autoplay
...ANSWER
Answered 2021-May-24 at 09:53You can include an attribute selector in the video selector to exclude the videos which have autoplay set on them when the page loads from the scroll update logic.
QUESTION
After searching for several days for a solution to my problem without any luck I decided to write a post here. I am currently building an one page website with html&css&jquery. My menu works great when I scroll up or down. It also works when I click on a menu link as it goes to the wanted section. The problem occurs when I scroll down or up a section and the active class stays on the clicked menu link.
Here is an example of my page
