Is there a method to trigger a unique function every time a user scrolls to a different div or section of the page?
Is there a method to trigger a unique function every time a user scrolls to a different div or section of the page?
This question has already been answered here: How to Implement Dynamic Scroll Position in Jquery
If you're looking for a solution, I recommend using the plugin called WAYPOINT
I've created an example on jsfiddle, feel free to check it out
HTML
<div class="first"></div>
<div class="second"></div>
CSS
.first {
background:green;
height: 600px;
width:100%;
}
.second {
background:red;
height: 600px;
width:100%;
}
JS
$('.second').waypoint(function() {
alert('You have reached a new entry.');
}, {
offset: '100%'
});
There are numerous approaches to accomplish this task. One of the simplest methods is as follows:
var targetElement = $('#my-div');
function displayAlert() {
alert('I am here!');
}
$(window).scroll(function(){
var viewportTop = $(window).scrollTop();
var viewportBottom = viewportTop + $(window).height();
var elementTop = $(targetElement).offset().top;
var elementBottom = elementTop + $(targetElement).height();
if ((elementBottom <= viewportBottom) && (elementTop >= viewportTop)) {
displayAlert();
}
});
Alternatively, you can utilize the jQuery Appear plugin or the Waypoints plugin:
$('#my-div').appear(function() {
alert('I am here!');
});
$('#my-div').waypoint(function() {
alert('I am here!');
});
