jQuery flash an element onclick and after scroll - javascript

So I have the following code:
$("#btn1").click(function(event) {
event.preventDefault();
$('html, body').animate({
scrollTop: $("#div").offset().top
}, 2000);
$("#div").addClass("flash");
setTimeout( function(){
$("#div").removeClass("flash"), 1000;
}, 1000);
});
When I click on the button it will scroll down to the div and flash its color (flash class). But what if the div is at the bottom of the page? I need the ode above to be changed so that the scrollTop is executed first AND is finished and then execute the next piece of code (the addClass and the setTimeout function). I assume I need to add a delay? Or something that checks whether the function is complete and if so, start the next one?

I think what you're looking for is animation callback. It's the forth parameter to the .animate() method: http://api.jquery.com/animate/
So in your case it would look like this:
$("#btn1").click(function(event) {
event.preventDefault();
$('html, body').animate({
scrollTop: $("#div").offset().top
},
2000,
'swing',
function () {
$("#div").addClass("flash");
setTimeout( function(){
$("#div").removeClass("flash"), 1000;
}, 1000);
});
});
Btw. it's a good practice to cache a jQuery selectors for optimisation (jQuery won't be searching the DOM for the queried nodes, and running the its constructor function each time).
I also refactored this code a bit for readability and to separate the flashing functionality, so you can either use it conveniently in such callbacks (in which case the function will get the animated element as this object, or just run it directly, passing it any jQuery element (e.g. flash($('.anything')))
$("#btn1").click(function(event) {
event.preventDefault();
$div = $('#div');
$('html, body').animate({
scrollTop: $div.offset().top
}, 2000, 'swing', flashElement});
});
function flashElement(element) {
element = element || this;
element.addClass("flash");
setTimeout( function(){
element.removeClass("flash"), 1000;
}, 1000);
}

You just need a callback...
$("#btn1").click(function(event) {
event.preventDefault();
$('html, body').animate({
scrollTop: $("#div").offset().top
}, 2000, function(){
$("#div").addClass("flash");
setTimeout( function(){
$("#div").removeClass("flash"), 1000;
}, 1000);
});
});

Scroll to a div after a few seconds

I am trying to smooth scroll to a div after about a minute on a page. I looked on here and found this answer but it did not help me as the person who gave the answer didn't really answer the person's question.
I'd prefer to use jQuery but I am open to JavaScript as well.
Here is what I have so far:
$(document).ready(function() {
$('body').delay(5000)
.animate({
'scrollTop': $('#usp').offset().top
}, 5000);
});
You can use Something like this which is quite easy.
Just Create a function with some name and call it after few seconds.
$(document).ready(function() {
function scrolltodiv(){
$('html, body').animate({
scrollTop: $("#myDiv").offset().top
}, 2000);
}
window.setTimeout( scrolltodiv, 5000 );
});
I hope this helps:
( function($){
setTimeout( function() {
$('html, body').animate({
scrollTop: $("#elementID").offset().top
// you can use $(".elementClass") but as ID should be unique, it would be better to use an element ID instead of classes
}, 2000);
// 2000 ms is the animation duration
}, 5000)
// it scrolls to #elementID after 5000 ms = 5 secs
} )(jQuery);
$(function(){
setTimeout(function(){
animate("#idorclass" ,2000)
}, 5000)
})
const animate = (idorclass, animval)=>{
$('html, body').animate({
scrollTop: $(idorclass).offset().top
}, animval);
}
also dynamic function that you can reuse

jQuery scroll does not scroll up

I have this code below and the DEMO fiddle.
jQuery(document).ready(function () {
$(window).scroll(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});
});
I'm really confused why I can't scroll up? Anybody can explain to me why and please share some solutions you have.
Any help, is very appreciated.
Alright, this should do what you are asking for. I don't think it is very user friendly, but that is up to you.
Demo Fiddle
//this prevents the animate method from running multiple times.
var scrolling = false;
jQuery(document).ready(function () {
$(window).scroll(function () {
if ( $(window).scrollTop() <= 100 && scrolling === false) {
//set to true to prevent multiple scrolls
scrolling = true;
//run the animation
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000, function() {
//when animation is complete, set scrolling to false
scrolling = false;
});
}
});
});
You can't scroll up because your code is wrapped in the scroll() function so it basically locks its position every time you try and scroll with either the mouses scroll wheel or arrow keys. If you amend to the following then it will position itself accordingly when the page first loads.
jQuery(document).ready(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});
Are you trying to have it animate when the link is clicked? If so you need to change your code:
jQuery(document).ready(function () {
$('a').click(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});
});
I would probably add a class or ID value to your link so you can target that one specific link. The code above would apply to all links on your page...although right now there is only the one.
<h1>Scroll to the Content</h1>
jQuery(document).ready(function () {
$('.scrollToContent').click(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});
});
I'm not sure if you will satisfied on this but i found something that can help a little on my problem.
jQuery(document).ready(function () {
$(this).bind('mousewheel', function(e){
if(e.originalEvent.wheelDelta /120 < 1) {
$('html, body').delay(200).animate({
scrollTop: $('#content').offset().top
}, 1000);
}
});
});
DEMO
No need to add the jquery functionality to achieve the requirement that has been asked. Please remove the Jquery code and run the code snippet provided in the fiddle. It is behaving as per the requirement.

waypoint js click to next div

Working on a function with waypoint.js that takes the current div in the viewport and finds the next div when clicking a button.
Currently I’m getting a undefined value for the ‘next’. Not sure what could be wrong I guess the value can’t move from the waypoint function to the click function. Any help would be lovely.
$('.wrap').waypoint(function() {
var next = $(this).next();
$(".button").click(function() {
$("html, body").animate({ scrollTop: next.offset().top }, 1000);
});
});
i suggest you to chain it instead of doing this in the callback:
$('.wrap').waypoint().addBack(this).find(".button").click(function() {
var next = $(this).closest('.wrap').next();
$("html, body").animate({ scrollTop: next.offset().top }, 1000);
});
or could be something like this:
$('.wrap').waypoint().done(function(){
$(this).find(".button").click(function() {
var next = $(this).closest('.wrap').next();
$("html, body").animate({ scrollTop: next.offset().top }, 1000);
});
});

Selection and focus on element of webpage not working (offset)

My question is a little tricky to explain, but I will try anyway. I have two horizontal tabs which, when you click on them, open a text box content. I'm trying to "focus" on them when they get clicked on. I've found a lot of material online but nothing works except for this code I'm showing below:
$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 500);
});
$(".accordionButtonone").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 500);
If I only click on the first accordionButton it works. If I click on the second accordionButton for first, it works. If I click on the first accordionButton after I've clicked on the second it works, but if I click on the second accordionButton after I click on the first it doesn't work: the focus remains at the bottom of the page. I don't know what could be the problem, I'm making some attempt with the animate function (jQuery tutorial) and the offset function (jQuery tutorial) but I would be grateful even only to know what is going wrong...
UPDATE: a partial solution is
$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 500);
});
$(".accordionButtonone").click(function() {
$('html, body').scrollTop(0);
});
$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).nextAll('div .accordionContent').offset().top
}, 500);
});
$(".accordionButtonone").click(function() {
$('html, body').animate({
scrollTop: $(this).nextAll('div .accordionContentone').offset().top
}, 500);
})
You have to put all that into a callback
$('.accordionContent').slideUp('normal', function(){
$(".accordionButtonone").click(function() {
$('html, body').animate({
scrollTop: $(this).nextAll('div .accordionContentone').offset().top
}, 500);
})
});
The solution is NOT elegant, but it works:
$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 10);
});
$(".accordionButtonone").click(function() {
$('html, body').scrollTop(458);
});
You are making it scroll down by using offset. remove the offset and it will stop scrolling down. also, instead of using individual selectors, why don't you write some code that utilizes jquery's 'this'
$(this)

Best way to smooth scrolling to an internal link

I've searched and see lots of examples about this subject but I couldn't best way for me.
I'm just a bit familiar with JS and jQuery and I want to ask about smooth scrolling.
<a name="urunler"></a>
<ul>
<li>Plastik Panjur</li>
<li>Alüminyum (İthal / Yalıtımlı) Panjur</li>
<li>Otomatik Panjur</li>
</ul>
I've a navigation like this. This scrolls instatly. But I want to do it slowly. Which is the shortest & easiest way for this? I'm more familiar to JS and I don't want to download and use JS plugins.
I need to know full syntax with a click method for my links (they all have same class)
Should I remove href park from links?
Waiting for your help & still searching
EDIT!!!: In this situation, I need only one class. Is it possible to give this property for multiple classes?
function scrollToElement (selector) {
$('html, body').animate({
scrollTop: $(selector).offset().top
}, 2000);
};
$(document).on('click', 'a.uruna', function () {
scrollToElement($(this).attr('href'));
});
I've got ('click', 'a.uruna', function (), how can I insert another class here or should I just write:
$(document).on('click', 'a.uruna', function () {
scrollToElement($(this).attr('href'));
});
$(document).on('click', 'a.new', function () {
scrollToElement($(this).attr('href'));
});
It can also be done in pure CSS using the following in your Style Sheet.
html{
scroll-behavior: smooth
}
HTML:
<ul>
<li>Plastik Panjur</li>
[...]
</ul>
JS:
function scrollToElement (selector) {
$('html, body').animate({
scrollTop: $(selector).offset().top
}, 2000);
};
$(document).on('click', 'a.uruna', function () {
scrollToElement($(this).attr('href'));
});
or
function scrollToElement (obj) {
$('html, body').animate({
scrollTop: obj.offset().top
}, 2000);
};
$(document).on('click', 'a.uruna', function () {
scrollToElement($(this));
});
I noticed that with JohnJohnGa's answer you get a "flicker" (at least for Google Chrome) where the page immediately pops to the anchor href position and back again before it scrolls there smoothly. This might not be noticeable with a fast computer, but it was definitely noticeable on the one I was working on. To get around this, I did the following:
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 1500, 'easeInOutExpo');
event.preventDefault();
window.history.pushState(null, null, $($anchor.attr('href')).selector);
});
Note, this prevents the default event from firing and then uses window.history.pushState to mimic it. For old browsers that don't support pushState it will scroll to the correct location, but it just won't update the address location.
Living demo: http://jsfiddle.net/wVEAy/2/
Note that for this case you would need to have an element with the same id as the one specified in the href tag of your link:
function scrollToElement (selector) {
$('html, body').animate({
scrollTop: $(selector).offset().top
}, 2000);
};
$(document).on('click', 'a.uruna', function () {
scrollToElement($(this).attr('href'));
});
