을 애니메이션으로 한 번만 재생하고 싶습니다. 그러나이 코드는 스크롤 할 때마다 실행됩니다.Jquery는 한 번만 스크롤 할 수 있습니다.
$(function() {
var oTop = $('#counter').offset().top - window.innerHeight;
$(window).scroll(function() {
var pTop = $('body').scrollTop();
if (pTop > oTop) {
start_count();
}
});
});
function start_count() {
(function ($) {
$.fn.countTo = function (options) {
// merge the default plugin settings with the custom options
options = $.extend({}, $.fn.countTo.defaults, options || {});
// how many times to update the value, and how much to increment the value on each update
var loops = Math.ceil(options.speed/options.refreshInterval),
increment = (options.to - options.from)/loops;
return $(this).each(function() {
var _this = this,
loopCount = 0,
value = options.from,
interval = setInterval(updateTimer, options.refreshInterval);
function updateTimer() {
value += increment;
loopCount++;
$(_this).html(value.toFixed(options.decimals));
if (typeof (options.onUpdate) == 'function') {
options.onUpdate.call(_this, value);
}
if (loopCount >= loops) {
clearInterval(interval);
value = options.to;
if (typeof (options.onComplete) == 'function') {
options.onComplete.call(_this, value);
}
}
}
});
};
$.fn.countTo.defaults = {
from: 0, // the number the element should start at
to: 100, // the number the element should end at
speed: 1000, // how long it should take to count between the target numbers
refreshInterval: 100, // how often the element should be updated
decimals: 0, // the number of decimal places to show
onUpdate: null, // callback method for every time the element is updated,
onComplete: null, // callback method for when the element finishes updating
};
})(jQuery);
