I have so far created
1. When an row is in view that elements slide in
2. Counters that counts up to a number.
I would like to improve no 2 so that counters start only when in view and also that they don't all go off at once but first on the left to start then when it finishes next counter to go off and so on.
Can someone please help me ?
This is my jsfiddle that i created with the same code: https://jsfiddle.net/DTcHh/32842/
//window and animation items
var animation_elements = $.find('.animation-element');
var web_window = $(window);
//check to see if any animation containers are currently in view
function check_if_in_view() {
//get current window information
var window_height = web_window.height();
var window_top_position = web_window.scrollTop();
var window_bottom_position = (window_top_position + window_height);
//iterate through elements to see if its in view
$.each(animation_elements, function() {
//get the element information
var element = $(this);
var element_height = $(element).outerHeight();
var element_top_position = $(element).offset().top;
var element_bottom_position = (element_top_position + element_height);
//check to see if this current container is visible (its viewable if it exists between the viewable space of the viewport)
if ((element_bottom_position >= window_top_position) && (element_top_position <= window_bottom_position)) {
element.addClass('in-view');
} else {
element.removeClass('in-view');
}
});
}
//on or scroll, detect elements in view
$(window).on('scroll resize', function() {
check_if_in_view()
})
//trigger our scroll event on initial load
$(window).trigger('scroll');
//Counter
$('.counter').each(function() {
var $this = $(this),
countTo = $this.attr('data-count');
$({ countNum: $this.text()}).animate({
countNum: countTo
},
{
duration: 8000,
easing:'linear',
step: function() {
$this.text(Math.floor(this.countNum));
},
complete: function() {
$this.text(this.countNum);
//alert('finished');
}
});
});
});
