I have 8 divs on my page. 4 at the top and 4 at the bottom. For the 4 divs at the top I have a piece of Javascript code that expands/unhides a div below them (see JSFiddle). I would like to make it so that when these divs are expanded the 4 divs at the bottom of the page hide. Then, when the div is unexpanded, the 4 divs at the bottom of the page show again.
Please see my JSFiddle: https://jsfiddle.net/44478c41/
I don't have much knowledge of Javascript but I had a fiddle around with my existing code to try and get it to work, I managed to hide the div but not the content within the div, nor was I able to get it to unhide again. Here is what I edited my code to:
$(document).ready(function() {
var $cont;
function tgl_conts(){
$('.static').stop().animate({height: 0},1200);
$cont.stop().animate({height:210},1200);
}
$('.tab_collapsable').on('click',function(){
var tabClass=$(this).attr('class').split(' ')[1];
$cont = $('.'+tabClass+':not(.tab_collapsable)');
var h = ($cont.height() === 0) ? tgl_conts() : ( $cont.stop().animate({height: 0},1200) );
});
});
Thanks a lot!
Here you go, you can either check the visibility of content divs or just track open/close via a flag
Here is the Fiddle
Handling via flag;
var bottomDivOpen=true;
function showHideBottomDiv(){
if(bottomDivOpen==true){
$(".static").hide();
bottomDivOpen=false;
}else{
$(".static").show();
bottomDivOpen=true;
}
}
Yet another solution:
$('.tab_collapsable').on('click',function(){
var tabClass = $(this).attr('class').split(' ')[1];
var h = $('.content.'+tabClass).height() ? 0 : 210;
$('.content').stop().animate({height: h},1200)
.not('.'+tabClass).stop().animate({height: 0},1200);
$('.static').stop().animate({height: h ? 0 : 250},1200);
});
JSFiddle
You can do something like this to retain animation effect on static divs.
$(document).ready(function() {
var $cont;
function tgl_conts(){
$('.content').stop().animate({height: 0},1200);
$cont.stop().animate({height:210},1200);
}
$('.tab_collapsable').on('click',function(){
var tabClass=$(this).attr('class').split(' ')[1];
$cont = $('.'+tabClass+':not(.tab_collapsable)');
if ($cont.height() === 0) {
tgl_conts();
$('.static').stop().animate({height: 0},1200);
} else {
$cont.stop().animate({height: 0},1200);
$('.static').stop().animate({height: 250},1200);
}
});
});

I need to make a search bar hide when scrolling down the page.
I know this is done in jquery, but I really have no clue where to start. I don't know the code I need and how/where to include it in Wordpress correctly.
This is where it is http://uwinat.o2clite.com/
Can someone help?
Thank you.
<script>
//when user start scrolling
jQuery(document).on("scroll", function () {
//hide search bar
jQuery('.header .search').removeClass('animated');
jQuery('.header-cont').removeClass('search-active');
});
</script>
Place this code at the bottom of the HTML page should be ok
someid - target
300 -means top offset px
visible - remove or add class and hide target by default
or reverse - add another class which hide elem on scroll
var foo = function() {
var arrow = document.getElementById('someid');
window.document.addEventListener('scroll', function() {
var topOffset = document.documentElement.scrollTop || document.body.scrollTop;
topOffset > 300 ? arrow.classList.add('visible') : arrow.classList.remove('visible');
});
};
foo();
i have one section inside 2 DIV's where the div's name 1st div and 2nd div . By Default 2nd div will be hidden, after scrolling 50% or more 1st div will be hidden and 2nd div will be displayed. How do i do that?
I used:
var heightDivid = $(window).height() / 2;
$(window).on('scroll', function(e){
$('.sections-class').each(function(){
if(this.getBoundingClientRect().top <= heightDivid ){
$(this).removeClass('heightDivids') ;
}
else{
$(this).addClass('heightDivids') ;
}
})
})
Perhaps you can alter something along these lines to do what you're attempting to do.
Utilize jQuery's scrollTop to identify where you want the change to occur.
Set a limit for when you want to hide the one div and show the two div.
$(window).scroll(function() {
var height = $(window).scrollTop();
if(height > 10) {
$('.two').show();
$('.one').hide();
}
});
Example: http://jsfiddle.net/xv2m4qn6/
If you want the effect to reverse simply add a second conditional:

At Last I did :) and it's work for me .... Thank you all for your help :)
var shadowEdgePoint = $(window).height() / 2;
$(window).on('scroll', function(e){
$('.section-class').each(function(){
if(this.getBoundingClientRect().top <= shadowEdgePoint){
$('.two').show();
$('.one').hide();
}
else{
$('.two').hide();
$('.one').show();
}
})
});
I am trying to add a class when the bottom of a div reaches the top of the window, but am not sure of how to do it.
I have managed to add the class when the top of the div gets to the top of the window, but am not having much luck with the bottom of the div.
Code I am using:
$(document).ready(function() {
var menuLinksTop = $('.container').offset().top;
var menuLinks = function(){
var scrollTop = $(window).scrollTop();
if (scrollTop > menuLinksTop) {
$('header').addClass('black-links');
} else {
$('header').removeClass('black-links');
}
};
menuLinks();
$(window).scroll(function() {
menuLinks();
});
Any help is appreciated.
You should use javascript's getBoundingClientRect() method, watch $(window).scroll event, and look at element's rectangle, its bottom value will give you what you need (if it's negative, your element is all the way up)
$(window).scroll(function() {
console.log($("div.watch")[0].getBoundingClientRect());
if ($("div.watch")[0].getBoundingClientRect().bottom < 0)
alert ("i'm out :3");
});
see jsFiddle http://jsfiddle.net/ja5nnbwr/2/
Add the height of the div. Assuming it is the .container :
var menuLinksTop = $('.container').offset().top + $('.container').height();
I have a function that adds more content to the container when the viewer has scrolled close to the place where the end of the container is. It works perfectly:
var elem = $('#cont');
var bo = $('body');
$(window).scroll(function(){
if (elem.outerHeight() - bo.scrollTop() - 350 <= 0) {
for(var i = 0; i < 3; i++){
elem.append('<div class="box"></div>');
$('.box').each(function(){
$(this).fadeIn('slow');
});
};
};
});
The issue, is if there is not enough content loaded originally, then it can't load more ever!
What I need to do:
I need to detect if the body cannot scroll. So I can append content until scrolling is possible. How can I do that?
Jsfiddle
You can do this :
while($(document).height() <= $(window).height()){
$('#cont').append($('<div/>', {class : 'box', style : 'display : block'}))
}
$('.box').hide().fadeIn('slow');
Fiddle : http://jsfiddle.net/FYtZX/1/
You can use this function to detect if something is scrollable.

Due to css properties my scrolling to div tags has too much margin-top. So I see jquery as the best solution to get this fixed.
I'm not sure why this isn't working, I'm very new to Js and Jquery. Any help us greatly appreciated.
Here is a quick look at Js. I found that when your div ids are in containers to change the ('html, body') to ('container)
Here is my jsfiddle
jQuery(document).ready(function($){
var prevScrollTop = 0;
var $scrollDiv = jQuery('div#container');
var $currentDiv = $scrollDiv.children('div:first-child');
var $sectionid = 1;
var $numsections = 5;
$scrollDiv.scroll(function(eventObj)
{
var curScrollTop = $scrollDiv.scrollTop();
if (prevScrollTop < curScrollTop)
{
// Scrolling down:
if ($sectionid+1 > $numsections) {
console.log("End Panel Reached");
}
else {
$currentDiv = $currentDiv.next().scrollTo();
console.log("down");
console.log($currentDiv);
$sectionid=$sectionid+1;
console.log($currentDiv.attr('id'));
var divid =$currentDiv.attr('id');
jQuery('#container').animate({scrollTop:jQuery('#'+divid).position().top}, 'slow');
}
}
else if (prevScrollTop > curScrollTop)
{
// Scrolling up:
if ($sectionid-1 == 0) {
console.log("Top Panel Reached");
}
else {
$currentDiv = $currentDiv.prev().scrollTo();
console.log("up");
console.log($currentDiv);
$sectionid=$sectionid-1;
var divid =$currentDiv.attr('id');
jQuery('html, body').animate({scrollTop:jQuery('#'+divid).position().top}, 'slow');
}
}
prevScrollTop = curScrollTop;
});
});
I'm not entirely sure what you want but scrolling to a <div> with jQuery is simpler than your code.
For example this code replaces the automatic jumping behaviour of anchors with smoother scrolling:
$(document).ready(function(e){
$('.side-nav').on('click', 'a', function (e) {
var $this = $(this);
var top = $($this.attr('href')).offset().top;
$('html, body').stop().animate({
scrollTop: top
}, 'slow');
e.preventDefault();
});
});
You can of course adjust the top variable by adding or removing from it like:
var top = $($this.attr('href')).offset().top - 10;
I have also made a fiddle from it (on top of your HTML): http://jsfiddle.net/Qn5hG/8/
If this doesn't help you or your question is something different, please clarify it!
EDIT:
Problems with your fiddle:
jQuery is not referenced
You don't need jQuery(document).ready() if the jQuery framework is selected with "onLoad". Remove the first and last line of your JavaScript.
There is no div#container in your HTML so it's no reason to check where it is scrolled. And the scroll event will never fire on it.
Your HTML is invalid. There are a lot of unclosed elements and random tags at the end. Make sure it's valid.
It's very hard to figure out what your fiddle is supposed to do.
