I have used window.location.hash to jump from a link on a page to a div on another page. This works well. However, when the new page opens, it shows first the top of the page and scrolls then down to the div. The code I used for this is given below.
Question: how can I change the code so that the new page is loaded at the div immediately, without scrolling (or jumping) from the top of the page to the div?
if (window.location.hash) {
setTimeout(function() {
$('html, body').scrollTop(0).show();
$('html, body').animate({
scrollTop: $(window.location.hash).offset().top
}, 1000)
}, 0);
}
else {
$('html, body').show();
}
I do it in this way because their is a timeout on the page during loading. When I do it in the normal way, thus without this code, it doesn't work because of the timeout. Any suggestions?
<script type="text/javascript">
var myVar;
function loadpage() {
myVar = setTimeout(showPage, 500);
}
function showPage() {
document.getElementById("loader").style.display = "none";
document.getElementById("myDiv").style.display = "block";
google.maps.event.trigger(map, 'resize')
map.setCenter(new google.maps.LatLng(50.849348, 4.7356652))
if (window.location.hash) {
setTimeout(function() {
$('html, body').scrollTop(0).show();
$('html, body').animate({
scrollTop: $(window.location.hash).offset().top
}, 0)
}, 0);
}
else {
$('html, body').show();
}
}
</script>

Requirement : I want to redirect to a new page on click of a button and then I want to scroll to a particular section on the new page.
Issue :
This is how I'm currently redirecting
<div class="button know-more-btn">
<a href="/about-us#Who-We-Are" target="" class="btn-link btn-small">
KNOW MORE</a>
</div>
Now once it redirects on click of the button,I want it to to scroll to a particular section on the new page.
I'm currently trying to achieve this scenario with the below code :-
$('.know-more-btn').click(function () {
if(location.hash == "#Who-We-Are"){
$('html, body').animate({
scrollTop: $(".map-section").offset().top
}, 1000);
}
});
So on click of the know-more-btn,it should check the location.hash and scroll to the map-section div class on the new page.
But it only redirects and does not scroll to the desired section.
Please help me solve this issue.
Your code:
$('.know-more-btn').click(function () {
if(location.hash == "#Who-We-Are"){
$('html, body').animate({
scrollTop: $(".map-section").offset().top
}, 1000);
}
});
New code:
if(location.hash == "#Who-We-Are"){
$('html, body').animate({
scrollTop: $(".map-section").offset().top
}, 1000);
$('.know-more-btn').click(function () {
if(location.hash == "#Who-We-Are"){
$('html, body').animate({
scrollTop: $(".map-section").offset().top
}, 1000);
}
});
this jquery/javascript code will help you
function hashchanged(){
if(location.hash.substr(1)!='') $('html,body').animate({ scrollTop: ($('#'+location.hash.substr(1)).position().top-200) }, 'slow');
}
$(window).on('hashchange', function(e){
hashchanged();
});
hashchanged();
Any question im here.
You don't need jQuery for this, there's a built in method on every HTMLElement called scrollIntoView
Add the following script to your about-us page:
const map = document.querySelector('#Who-We-Are .map-section')
// simulates arriving at #Who-We-Are for the purpose of this example
window.location.hash = 'Who-We-Are';
addEventListener('DOMContentLoaded', event => {
if (window.location.hash === 'Who-We-Are') {
map.scrollIntoView({behavior: "smooth", block: "start"});
}
});
#Who-We-Are {
margin-top: 110vh;
}
.map-section {
margin-top: 20vh;
}
<section id="Who-We-Are">
<h2>Who We Are</h2>
<div class="map-section">Map</div>
</section>
this is my best solution which i had never seen this before. maybe this helpful for you.
below code for the page from that i want to redirect on click a link.
<div ><a onclick="myHash()"></a></div>
this is to redirect to a new page and send hash through url.
function myHash() {
$(document).ready(function () {
window.location.href="contact.html#link"
});
}
}
And On new page which i want open and scroll to the specific div.
<div id="link"></div>
And using url's hash to scroll specific div on new page
$(document).ready(function() {
if (window.location.hash) {
setTimeout(function() {
$('html, body').scrollTop(0).show();
$('html, body').animate({
scrollTop: $(window.location.hash).offset().top
}, 1500)
}, 0);
}
});
Using this javascript to scroll to a div (#Content) after a 5s delay using setTimeout.
setTimeout(function () {
$('html, body').animate({ scrollTop: $('#Content').offset().top - 0 }, 1000);
}, 5000);
How would I go about cancelling this action if the user scrolls manually before the 5s is elapsed. Reason being if the user has scrolled they'll be annoyed if the page then auto scrolls.
Tried putting it in window.load and checking for if ($(window).scrollTop() == 0) but of course that's always true at window.load, and isn't cancelled by the user scrolling manually.
Thanks!
you can use for example global variable and check if its set up by event scroll
var scrolled = false;
$(document).scroll(function(){scrolled = true;});
setTimeout(function () {
if (!scrolled){
$('html, body').animate({ scrollTop: $('#Content').offset().top - 0 },
1000); }
}
}, 5000);
You shall define your timeout into a variable to be able to cancel it with clearTimeout
See full documentation here : https://www.w3schools.com/jsref/met_win_cleartimeout.asp
Just add an event to check oyur scroll and cleart your timeout if scrolled
For example :
var myVar = setTimeout(function(){
$('html, body').animate({ scrollTop: $('#Content').offset().top - 0 }, 1000);
}, 5000);
and to cancel your scroll :
$(document).scroll(function(){
clearTimeout(myVar)
}
You can clear the timeout as others have shown, or you can let it run but perform the scrollTop check inside before starting the scroll animation:
setTimeout(function () {
if ($(window).scrollTop() == 0) {
$('html, body').animate({ scrollTop: $('#Content').offset().top - 0 }, 1000);
}
}, 5000);
You can run the logic for checking the scroll by adding an event hanlder for scroll and then removing the event handler once it is done checking as it needs to be run only once. Also, You can clear the setTimeout by using the clearTimeout in the eventHandler Code.
window.addEventListener('scroll', scrollEventHandler);
function scrollEventHandler(e){
clearTimeout(...setTimeoutid) // Pass in setTimeout Id.
}
setTimeout(function () {
$('html, body').animate({ scrollTop: $('#Content').offset().top - 0 }, 1000);
window.removeEventListener('scroll', scrollEventHandler);
}, 5000);
I used jQuery to load a new page and scroll to a specific div. Everything worked perfectly but I have a small problem. Every time the link opens right before it scrolls there is a flashing.
Here is the code:
<a id="about1" href="Main.html#aboutSection" alt="About"> ABOUT </a></li>
here is the script:
$(document).ready(function() {
$('html, body').hide();
if (window.location.hash) {
setTimeout(function() {
$('html, body').scrollTop(0).show();
$('html, body').animate({
scrollTop: $(window.location.hash).offset().top
- 86}, 1000)
}, 0);
} else {
$('html, body').show();
} )};
I hope was clear enough.
Thanks guys.
P.S: I am new to web programming. This code is not mine.
You are seeing a blink because you are hiding all your contents with:
$('html, body').hide();
Is there a reason you want to hide the whole page? If not you can just try the following
$(document).ready(function() {
if (window.location.hash) {
$('html').animate({
scrollTop: $(window.location.hash).offset().top
- 86}, 1000);
}
});
I am creating a form where i have many child forms to submit,so i have used a jQuery functionality where each submit a msg will show at the top of the page ,now what i want,on each submit the page will scroll up to the div where that jQuery is calling .Here is my code
var url = "<%=addPersonalDetailsURL%>";
var type = "addPersonalDetails";
if(!($('#<portlet:namespace/>address1').val()=='' || $('#country').val()=='None' ||$('#<portlet:namespace/>primaryPhone').val()=='')){
jQuery.getJSON(url+"&address1="+address1+"&address2="+address2+"&country="+country+"&state="+state+"&city="+city+"&zip="+zip+"&skypeId="+skypeId+"&twitter="+twitter+"&primaryPhone="+primaryPhone+"&secondaryPhone="+secondaryPhone+"&type="+type, function(data) {
$('html, body').animate({
scrollTop: $(".success").offset().top
}, 800);
for(var z=0; z<data.applicationArray.length;z++){
applicationArray = data.applicationArray[z].split("$$##$$##");
address1 = applicationArray[0];
address2 = applicationArray[1];
city = applicationArray[2];
primaryPhone = applicationArray[3];
}
jQuery.getJSON is giving some result where on the basis i have to use that functionality.So can you tell how i should modify your solution
You should need to get your element's top position in the page and move the scroll to that position. Something like the code below:
jQuery(window).scrollTop(jQuery(".success").offset().top);
Note that the code above will move to the first .success position. If you have to reference a specific one, add the index in the selector, for example:
jQuery(window).scrollTop(jQuery(".success:eq(1)").offset().top);
You can do that with this function:
$("button").click(function () {
$('html, body').animate({
scrollTop: $(".whichElement").offset().top
}, 800);
});
Explanation:
If the button is clicked, we scroll the page to the element with class
whichElement and the duration of the scroll is 800ms.
Example:
$(".first-hey").click(function () {
$('html, body').animate({
scrollTop: $(".second-hey").offset().top
}, 800);
});
$(".second-hey").click(function () {
$('html, body').animate({
scrollTop: $(".third-hey").offset().top
}, 800);
});
$(".third-hey").click(function () {
$('html, body').animate({
scrollTop: $(".first-hey").offset().top
}, 800);
});
.divide {
height: 1300px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="first-hey">First hey</button>
<div class="divide"></div>
<button class="second-hey">Second hey</button>
<div class="divide"></div>
<button class="third-hey">Third hey</button>
I'm trying to implement some JavaScript code I found here on stackoverflow to make a smooth transition between one link on a page and other section in other page using the standar:
<a href="example.html#anchor">
The issues is that when the user clik the link, 1 second white flash appears before the smooth scroolling makes. I dont like this behavior for the "User Experience"
How can I to prevent this?
The JavaScript:
(function($){
var jump=function(e)
{
if (e){
e.preventDefault();
var target = $(this).attr("href");
}else{
var target = location.hash;
}
$('html,body').animate(
{
scrollTop: $(target).offset().top
},1000, function()
{
location.hash = target;
});
}
$('html, body').hide()
$(document).ready(function()
{
$('a[href^=#]').bind("click", jump);
if (location.hash){
setTimeout(function(){
$('html, body').scrollTop(0).show()
jump()
}, 0);
}else{
$('html, body').show()
}
});
})(jQuery)
Thanks.
