Is it possible to trigger an action when a user starts scrolling using the mousewheel? I've searched online but all I found was information on 100% scroll on click. I want the window to automatically be scrolled down to 100% as soon as the user starts scrolling with their mousewheel. Can this be done? Thank you!
To begin with: The issue that arises when trying to forcefully scroll the screen all the way down is that it restricts any further movement on the screen - since each scroll action resets the position.
One approach to address this is by utilizing JQuery and monitoring the scroll event.
Here's an example:
$(document).on('scroll', function(){
console.log('yeah');
// window.scrollTo(0,document.body.scrollHeight); // left this commented out
});
You can achieve the same without JQuery as well, just using plain JavaScript
document.onscroll = function(){
console.log('oh yeah');
// window.scrollTo(0,document.body.scrollHeight); // left this commented out
}
For those interested, there is a great resource available called the jQuery Mousewheel plugin which can be found at http://plugins.jquery.com/mousewheel/
A simple solution would be to use the following code:
$(window).on("wheel", function (e) {
if (e.deltaY > 0) // Make sure to determine whether to compare greater than or less than based on your needs
$("html, body").scrollTop(10000000000);
});If you're looking for a way to detect any scroll on the page, rather than just mousewheel scrolling specifically, this code might be what you need. It uses jQuery so make sure that's suitable for your project.
$( document ).ready(function() {
$(window).scroll(function (event) {//Checks if scroll happens
//set the left offset to 0, set the second one to the height of the document
window.scroll(0,document.body.scrollHeight);
});
});
Keep in mind, this script will be triggered by any scroll movement.
1) Insert an unseen hyperlink:
<a id="invisible-scroll-link" href="#end" style="color:black">...</a>
2) When the mouse wheel is scrolled:
$(window).bind("wheel", function (e) {
if (e.deltaY > 0) {
$('#invisible-scroll-link').trigger('click');
}
});
