I decided to take off jQuery library and to do my own functions.
I started with Animation because I need it.
So, I store the interval ID and other datas on Element Object, in animate function I can see the property, but in another function, with same element, I can't see my property.
How I can make them global or something?

Press on one box, wait a while (to the middle maybe) and click again. After this wait to animation stop.
You will see in console the same element, but when you clicked in animation progress you will not see the property Animation.

setTimeout(function() {

I want convert a part of this below customized script to angular js.
mlmenu = new MLMenu(menuEl, {
// breadcrumbsCtrl : true, // show breadcrumbs
// initialBreadcrumb : 'all', // initial breadcrumb text
backCtrl : false, // show back button
// itemsDelayInterval : 60, // delay between each menu item sliding animation
onItemClick: loadDummyData // callback: item that doesn´t have a submenu gets clicked - onItemClick([event], [inner HTML of the clicked item])
});
I use it as this in angular but it has error .
$scope.menuEl = document.getElementById('ml-menu');
var menuEl = document.getElementById('ml-menu'),
mlmenu = new MLMenu(menuEl, {
// breadcrumbsCtrl : true, // show breadcrumbs
// initialBreadcrumb : 'all', // initial breadcrumb text
backCtrl: false, // show back button
// itemsDelayInterval : 60, // delay between each menu item sliding animation
onItemClick: $scope.loadDummyData // callback: item that doesn´t have a submenu gets clicked - onItemClick([event], [inner HTML of the clicked item])
});
How can I do it ?
I think you should wrap your plugin with AngularJS directive https://docs.angularjs.org/guide/directive
I.e. create directive that uses your plugin and initialize it on marked DOM.
angular.module('yourModule')
.directive('mlMenu', function() {
return {
restrict: 'A',
link: function (scope, element) {
var mlmenu = new MLMenu(element,
...
}
};
});
Than in HTML
<div data-ml-menu></div>
And if you are going to modify scope in plugin listeners do not forget to use scope.$apply() wrapper.
I am using infinite scroll to load posts and tried to integrate a custom like button for every single posts that needs a small jquery script to work. My problem is I added this Jquery directly after the sucess in ajax load posts. But when I load eg the 3. page my jquery script executes twice and on the posts of the 2nd page the lke buttons are not working correctly. How can I handle this? If I dont execute the code after the ajax request and only call this jquery code globally the like buttons do not work in the new loaded posts of the ajax infinite scroll. Maybe I need to stop the sript of before when eg loadin 3. page through the ajax infinite scroll but how? This is my code:
function load_more_posts(selector){

var data;
loading = true;

url: url,

There's a great plugin for scrolling. He has methods such as bund, unbind, destroy and e.t.c.:
https://github.com/infinite-scroll/infinite-scroll#methods
i have download the slider from this Site
I am trying to get this Slider to auto play but I can't seem to get it to work, Does anyone know how I can achieve this? i tried to play with the below code but can not get what i want.
function init() {
[].forEach.call(document.querySelectorAll('.tt-grid-wrapper'), function (el) {
var grid = el.querySelector('.tt-grid'),
items = [].slice.call(grid.querySelectorAll('li')),
navDots = [].slice.call(el.querySelectorAll('nav > a')),
isAnimating = false,
current = 0;
navDots.forEach(function (el, i) {
el.addEventListener(eventtype, function (ev) {
if (isAnimating || current === i) return false;
ev.preventDefault();
isAnimating = true;
updateCurrent(i);
loadNewSet(i);
});
});
You can try something like this:
function init() {
[].forEach.call(document.querySelectorAll('.tt-grid-wrapper'), function (el) {
var grid = el.querySelector('.tt-grid'),
items = [].slice.call(grid.querySelectorAll('li')),
navDots = [].slice.call(el.querySelectorAll('nav > a')),
isAnimating = false,
current = 0;
navDots.forEach(function (el, i) {
el.addEventListener(eventtype, function (ev) {
if (isAnimating || current === i) return false;
ev.preventDefault();
isAnimating = true;
updateCurrent(i);
loadNewSet(i);
});
});
var delay = 1000;
var num_frames = 4;
var i = 1;
setTimeout( function() {
if (isAnimating || current === i) return false;
isAnimating = true;
updateCurrent(i);
loadNewSet(i);
i >= 4 ? i = 0 : i++;
} , delay);
};
I have set up a fiddle
http://jsfiddle.net/austinind/aadcd/1/
what I am trying to achieve is a parallax effect.
the div should scoll up and down based on the scolling.
in my case the div only scrolls up:
function parallax(){
var scrolled = $(window).scrollTop();
var elempos=$(".bg2").position().top;
$('.bg2').css('top', elempos-(scrolled * 0.2) + 'px');
}
$(window).scroll(function(e){
parallax();
});
Take a look at following Js fiddle

});
function handler(event) {

event.type = "mousewheel";
// Old school scrollwheel delta
if ( orgEvent.wheelDelta ) { delta = orgEvent.wheelDelta/120; }
if ( orgEvent.detail ) { delta = -orgEvent.detail/3; }
// New school multidimensional scroll (touchpads) deltas
deltaY = delta;
// Gecko
if ( orgEvent.axis !== undefined && orgEvent.axis === orgEvent.HORIZONTAL_AXIS ) {
deltaY = 0;

}
// Webkit
if ( orgEvent.wheelDeltaY !== undefined ) { deltaY = orgEvent.wheelDeltaY/120; }
if ( orgEvent.wheelDeltaX !== undefined ) { deltaX = -1*orgEvent.wheelDeltaX/120; }
// Add event and delta to the front of the arguments
args.unshift(event, delta, deltaX, deltaY);
return ($.event.dispatch || $.event.handle).apply(this, args);
}
})(jQuery);
// OUR CODE
var winH = $(window).height();
$('.page').height(winH);
var c = 0;
var pagesN = $('.page').length;
$(document).bind('mousewheel', function(ev, delta) {
delta>0 ? --c : ++c ;

Your script is working fine, your actual problem is your CSS
Remove
position:Fixed
for the class bg2, And it will work fine

I am having trouble getting my scroll to top button to work. I know its a problem with another animation but I am not able to see what is causing the issue. The problem is when the other animation "starts when scroll hits 500" the scroll to top button will no longer fade out and disappear.
$.chain = function() {
var promise = $.Deferred().resolve().promise();
jQuery.each( arguments, function() {
promise = promise.pipe( this );
});
return promise;
};
function scrollTop(){
if(typeof pageYOffset!= 'undefined'){
return pageYOffset;
}
else{
var b = document.body; //IE 'quirks'
var d = document.documentElement; //IE with doctype
d = (d.clientHeight)? d : b;
return d.scrollTop;
}
}
$(window).on("scroll", function(){
if(scrollTop() >= 600){
$(window).off("scroll");
var animations = $.chain(function() {
return $('#animate1 img').fadeIn('slow').delay(400);
}, function() {
return $('#animate2 img').fadeIn('slow').delay(400);
}, function() {
return $('#animate3 img').fadeIn('slow');
});
};
});
jQuery(document).ready(function() {
var offset = 300;
var duration = 500;
jQuery(window).scroll(function() {
if (jQuery(this).scrollTop() > offset) {
jQuery('.scroll-top').fadeIn(duration);
} else {
jQuery('.scroll-top').fadeOut(duration);
}
});
});
Thank you for any help.
$(window).off("scroll"); is indeed removing scroll event which you're listening to fadeIn and fadeOut.
Although i havent tried it but an alternative would be to use event namespacing?
something like below:
$.chain = function() {
var promise = $.Deferred().resolve().promise();
