I want to make it that i scroll towards the section that i click on in my navbar but for some reason the window wont scroll when i click and i get no errors can someone help me, want to accomplish this in vanilla js.
(function() {
var scrollLinks = document.querySelectorAll('.scroll');
for( var i = 0; i < scrollLinks.length; i++){
scrollLinks[i].addEventListener('click', function(e){
e.preventDefault();
this_ = this;
var position = this_.getAttribute("href");
scrollIt(position);
})
}
function scrollIt(position){
console.log(document.querySelector(position).offsetTop)
window.scrollTo({
top: document.querySelector(position).offsetTop,
left: 0,
behavior: 'smooth',
});
}
})();

You need to make sure that the href attribute has a leading # character because you are passing this directly to the .querySelector() method and also your sections need to have matching ids. Check this out (your JavaScript code is not changed at all, I only added valid HTML to it):
(function() {
var scrollLinks = document.querySelectorAll('.scroll');
for( var i = 0; i < scrollLinks.length; i++){
scrollLinks[i].addEventListener('click', function(e){
e.preventDefault();
this_ = this;
var location = this_.getAttribute("href");
scrollIt(location);
})
}
function scrollIt(location){
console.log(document.querySelector(location).offsetTop)
window.scrollTo({
top: document.querySelector(location).offsetTop,
left: 0,
behavior: 'smooth',
});
}
})();

Show a series of images on scroll

The closest solution I found is Show div on scrollDown after 800px.
I'm learning HTML, CSS, and JS, and I decided to try to make a digital flipbook: a simple animation that would play (ie, load frame after frame) on the user's scroll.
I figured I would add all the images to the HTML and then use CSS to "stack them" in the same position, then use JS or jQuery to fade one into the next at different points in the scroll (ie, increasing pixel distances from the top of the page).
Unfortunately, I can't produce the behavior I'm looking for.
HTML (just all the frames of the animation):
<img class="frame" id="frame0" src="images/hand.jpg">
<img class="frame" id="frame1" src="images/frame_0_delay-0.13s.gif">
CSS:
body {
height: 10000px;
}
.frame {
display: block;
position: fixed;
top: 0px;
z-index: 1;
transition: all 1s;
}
#hand0 {
padding: 55px 155px 55px 155px;
background-color: white;
}
.frameHide {
opacity: 0;
left: -100%;
}
.frameShow {
opacity: 1;
left: 0;
}
JS:
frame0 = document.getElementById("frame0");
var myScrollFunc = function() {
var y = window.scrollY;
if (y >= 800) {
frame0.className = "frameShow"
} else {
frame0.className = "frameHide"
}
};
window.addEventListener("scroll", myScrollFunc);
};

One of your bigger problems is that setting frame0.className = "frameShow" removes your initial class frame, which will remove a bunch of properties. To fix this, at least in a simple way, we can do frame0.className = "frame frameShow", etc. Another issue is that frame0 is rendered behind frame1, which could be fixed a variety of ways. ie. Putting frame0's <img> after frame1, or setting frame0's CSS to have a z-index:2;, and then setting frame0's class to class="frame frameHide" so it doesn't show up to begin with. I also removed the margin and padding from the body using CSS, as it disturbs the location of the images. I have made your code work the way I understand you wanted it to, here is a JSFiddle.

It depends on your case, for example, in this jsFiddle 1 I'm showing the next (or previous) frame depending on the value of the vertical scroll full window.
So for my case the code is:
var jQ = $.noConflict(),
frames = jQ('.frame'),
win = jQ(window),
// this is very important to be calculated correctly in order to get it work right
// the idea here is to calculate the available amount of scrolling space until the
// scrollbar hits the bottom of the window, and then divide it by number of frames
steps = Math.floor((jQ(document).height() - win.height()) / frames.length),
// start the index by 1 since the first frame is already shown
index = 1;
win.on('scroll', function() {
// on scroll, if the scroll value equal or more than a certain number, fade the
// corresponding frame in, then increase index by one.
if (win.scrollTop() >= index * steps) {
jQ(frames[index]).animate({'opacity': 1}, 50);
index++;
} else {
// else if it's less, hide the relative frame then decrease the index by one
// thus it will work whether the user scrolls up or down
jQ(frames[index]).animate({'opacity': 0}, 50);
index--;
}
});
Update:
Considering another scenario, where we have the frames inside a scroll-able div, then we wrap the .frame images within another div .inner.
jsFiddle 2
var jQ = $.noConflict(),
cont = jQ('#frames-container'),
inner = jQ('#inner-div'),
frames = jQ('.frame'),
frameHeight = jQ('#frame1').height(),
frameWidth = jQ('#frame1').width() + 20, // we add 20px because of the horizontal scroll
index = 0;
// set the height of the outer container div to be same as 1 frame height
// and the inner div height to be the sum of all frames height, also we
// add some pixels just for safety, 20px here
cont.css({'height': frameHeight, 'width': frameWidth});
inner.css({'height': frameHeight * frames.length + 20});
cont.on('scroll', function() {
var space = index * frameHeight;
if (cont.scrollTop() >= space) {
jQ(frames[index]).animate({'opacity': 1}, 0);
index++;
} else {
jQ(frames[index]).animate({'opacity': 0}, 0);
index--;
}
});
** Please Note that in both cases all frames must have same height.

I have an image.
I want to show different divs as popup when user clicks on particular area of the image.
I want to do it using jquery & html.
Can any one help me with this.

Here is an example of sample solution: http://jsfiddle.net/htEvT/2/
JavaScript
$('#rabbit').click(function (e) {
var offset = $(this).offset(),
left = e.pageX - offset.left,
top = e.pageY - offset.top;
if (top > $(this).height() / 2) {
alertDiv('You\'ve cliked under the middle.', 'alert-white');
} else {
alertDiv('You\'ve cliked above the middle.', 'alert-gray');
}
});
function alertDiv(text, cssClass) {
var alrt = $('<div class="alert ' + cssClass + '">' + text + '</div>');
$(document.body).append(alrt);
alrt.click(function () {
alrt.remove();
});
}
​
CSS
.alert {
position: absolute;
left: 30px;
top: 30px;
width: 300px;
height: 200px;
border: 1px solid black;
}
.alert-white {
background: white;
}
.alert-gray {
background: #ccc;
}

If there are any issues with my solution please let me know. :)

Use Image Map on image and attach fancy box on different sections of image. Since, you have not posted code so I can't provide coding solution for the same.

Something like below should give you an Idea how to do this:
$("img").click(function() {
$("body").append("<div class='newdiv'></div>")
})
.newdiv{width:100px; height:300px;border:1px solid red;}

My favorite is Fancybox.
I'm yet to see something it cannot do. Great documentation and widely used so if you need help there is a high chance somebody else has asked the same question, and can be resolved with a simple google.

Create a DIV named "imgbox" on the HTML page on which your thumbnail images will be shown. The DIV and the CSS element ID associated with the DIV is shown below
<div id="imgbox"></div>
the css
#imgbox
{
vertical-align : middle;
position : absolute;
border: 1px solid #999;
background : #FFFFFF;
filter: Alpha(Opacity=100);
visibility : hidden;
height : 200px;
width : 200px;
z-index : 50;
overflow : hidden;
text-align : center;
}
Here is the JavaScript code to show the popup image:
Get the left and top positions of the thumbnail image:
function getElementLeft(elm)
{
var x = 0;
//set x to elm’s offsetLeft
x = elm.offsetLeft;
//set elm to its offsetParent
elm = elm.offsetParent;
//use while loop to check if elm is null
// if not then add current elm’s offsetLeft to x
//offsetTop to y and set elm to its offsetParent
while(elm != null)
{
x = parseInt(x) + parseInt(elm.offsetLeft);
elm = elm.offsetParent;
}
return x;
}
function getElementTop(elm)
{
var y = 0;
//set x to elm’s offsetLeft
y = elm.offsetTop;
//set elm to its offsetParent
elm = elm.offsetParent;
//use while loop to check if elm is null
// if not then add current elm’s offsetLeft to x
//offsetTop to y and set elm to its offsetParent
while(elm != null)
{
y = parseInt(y) + parseInt(elm.offsetTop);
elm = elm.offsetParent;
}
return y;
}
Get the thumbnail image source, make the DIV visible, increase the height and width to the required size, and attach the image to the DIV.
function Large(obj)
{
var imgbox=document.getElementById("imgbox");
imgbox.style.visibility='visible';
var img = document.createElement("img");
img.src=obj.src;
img.style.width='200px';
img.style.height='200px';
if(img.addEventListener){
img.addEventListener('mouseout',Out,false);
} else {
img.attachEvent('onmouseout',Out);
}
imgbox.innerHTML='';
imgbox.appendChild(img);
imgbox.style.left=(getElementLeft(obj)-50) +'px';
imgbox.style.top=(getElementTop(obj)-50) + 'px';
}
Hide the DIV at mouse out.
function Out()
{
document.getElementById("imgbox").style.visibility='hidden';
}
Add a OnMouseOver client-side event call for the thumbnail images to show the popup image on mouse-over.
<img id='img1' src='images/Sample.jpg' onmouseover="Large(this)" />

If the area is square, you can place a transparent element over the desired area, and give it a simple onClick event.

Use SimpleModal
You can use the plugin SimpleModal to achieve what you wanna do.
SimpleModal is a lightweight jQuery Plugin which provides a powerful interface for modal dialog development. Think of it as a modal dialog framework. SimpleModal gives you the flexibility to build whatever you can envision, while shielding you from related cross-browser issues inherent with UI development.
Using that, you can either call an already existing div or create a modal on the fly.
Calling an existing div:
$("#element-id").modal();
Making a modal on the fly:
$.modal("<div><h1>SimpleModal</h1></div>");
Giving options:
$("#element-id").modal({options});
$.modal("<div><h1>SimpleModal</h1></div>", {options});

Scrollpane on the bottom, css is hacky, javascript is hard

I want to put a bar on the bottom of my page containing a varying number of pictures, which (if wider than the page) can be scrolled left and right.
The page width is varying, and I want the pane to be 100% in width.
I was trying to do a trick by letting the middle div overflow and animate it's position with jquery.animate().
Like this:
Here is a fiddle without the js: http://jsfiddle.net/SoonDead/DdPtv/7/
The problems are:
without declaring a large width to the items holder it will not overflow horizontally but vertically. Is this a good hack? (see the width: 9000px in the fiddle)
I only want to scroll the middle pane if it makes sense. For this I need to calculate the width of the overflowing items box (which should be the sum of the items' width inside), and the container of it with the overflow: hidden attribute. (this should be the width of the browser window minus the left and right buttons).
Is there a way to calculate the length of something in js without counting all of it's childrens length manually and sum it up?
Is there a way to get the width of the browser window? Is there a way to get a callback when the window is resized? I need to correct the panes position if the window suddenly widens (and the items are in a position that should not be allowed)
Since the window's width can vary I need to calculate on the fly if I can scroll left or right.
Can you help me with the javascript?
UPDATE: I have a followup question for this one: Scroll a div vertically to a desired position using jQuery Please help me solve that one too.

Use white-space:nowrap on the item container and display:inline or display:inline-block to prevent the items from wrapping and to not need to calculate or set an explicit width.
Edit:: Here's a live working demo: http://jsfiddle.net/vhvzq/2/
HTML
<div class="hscroll">
<ol>
<li>...</li>
<li>...</li>
</ol>
<button class="left"><</button>
<button class="right">></button>
</div>
CSS
.hscroll { white-space:nowrap; position:relative }
.hscroll ol { overflow:hidden; margin:0; padding:0 }
.hscroll li { list-style-type:none; display:inline-block; vertical-align:middle }
.hscroll button { position:absolute; height:100%; top:0; width:2em }
.hscroll .left { left:0 }
.hscroll .right { right:0 }
JavaScript (using jQuery)
$('.hscroll').each(function(){
var $this = $(this);
var scroller = $this.find('ol')[0];
var timer,offset=15;
function scrollLeft(){ scroller.scrollLeft -= offset; }
function scrollRight(){ scroller.scrollLeft += offset; }
function clearTimer(){ clearInterval(timer); }
$this.find('.left').click(scrollLeft).mousedown(function(){
timer = setInterval(scrollLeft,20);
}).mouseup(clearTimer);
$this.find('.right').click(scrollRight).mousedown(function(){
timer = setInterval(scrollRight,20);
}).mouseup(clearTimer);
});

Thanks Phrogz for this part -- give the image container the white-space: nowrap; and display: inline-block;.
You can calculate the width without having to calculate the width of the children every time but you will need to calculate the width of the children once.
//global variables
var currentWidth = 0;
var slideDistance = 0;
var totalSize = 0;
var dispWidth = (winWidth / 2); //this should get you the middle of the page -- see below
var spacing = 6; //padding or margins around the image element
$(Document).Ready(function() {
$("#Gallery li").each(function () {
totalSize = totalSize + parseFloat($(this).children().attr("width"));// my images are wrapped in a list so I parse each li and get it's child
});
totalSpacing = (($("#Gallery li").siblings().length - 1) * spacing); //handles the margins between pictures
currentWidth = (parseFloat($("#Gallery li.pictureSelected").children().attr("width")) + spacing);
maxLeftScroll = (dispWidth - (totalSize + totalSpacing)); //determines how far left you can scroll
});
function NextImage() {
currentWidth = currentWidth + (parseFloat($("#Gallery li.pictureSelected").next().children().attr("width")) + spacing); //gets the current width plus the width of the next image plus spacing.
slideDistance = (dispWidth - currentWidth)
$("#Gallery").animate({ left: slideDistance }, 700);
}
There is a way to get the browser window with in javascript (jQuery example).
and there is a way to catch the resize event.
var winWidth = $(window).width()
if (winWidth == null) {
winWidth = 50;
}
$(window).resize(function () {
var winNewWidth = $(window).width();
if (winWidth != winNewWidth) {
window.clearTimeout(timerID);
timerID = window.setInterval(function () { resizeWindow(false); }, 100);
}
winWidth = winNewWidth;
});
On my gallery there's actually quite a bit more but this should get you pointed in the right direction.

You need to change your #items from
#items
{
float: left;
background: yellow;
width: 9000px;
}
to
#items {
background: yellow;
}
Then calculate the width very easily with jQuery
// #items width is calculated as the number of child .item elements multiplied by their outerWidth (width+padding+border)
$("#items").width(
$(".item").length * $(".item").outerWidth()
);
and simply declare click events for the #left and #right elements
$("#left").click(function() {
$("#middle").animate({
scrollLeft: "-=50px"
}, 'fast');
});
$("#right").click(function() {
$("#middle").animate({
scrollLeft: "+=50px"
}, 'fast');
});
jsFiddle link here
EDIT
I overlooked that detail about the varying image widths. Here is the correct way to calculate the total width
var totalWidth = 0;
$(".item").each(function(index, value) {
totalWidth += $(value).outerWidth();
});
$("#items").width(totalWidth);

How can I Animate an Element to its natural height using jQuery [duplicate]

This question already has answers here:
Animate element to auto height with jQuery
(21 answers)
Closed 7 years ago.
I'm trying to get an element to animate to its "natural" height - i.e. the height it would be if it had height: auto;.
I've come up with this:
var currentHeight = $this.height();
$this.css('height', 'auto');
var height = $this.height();
$this.css('height', currentHeight + 'px');
$this.animate({'height': height});
Is there a better way to do this? It feels like a bit of a hack.
Edit:
Here's a complete script to play with for anyone that wants to test.

</html>

I permit myself to answer this thread, even if it's been answered a long time ago, cuz it just helped me.
In fact, i don't understand the first answer : why opening a half-closed element to get its height, and then closing it again ?
At the beginning, you hide the element so that just a part of it appears, right ? The best way (i believe) to do this is onready, with javascript. So, when you hide the element onready, just save the orig height in a var, so you don't have to hide(onready)-show-save height-hide to be able to toggle the elements visibility.
Look at what i did, it works perfectly :
$(document).ready(function(){
var origHeight = $("#foo").css('height');
$("#foo").css({"height" : "80px"});
$("#foo .toggle").bind("click", function(event){ toggleFoo(event, lastSearchesMidHeight); });
});
Here, when you call your toggle function, you know what is your original element height without wanking around.
I wrote it fast, hoping it could help someone in the future.

the easiest solution I found was to simply wrap the content element with a div that is limited in height and set to overflow:hidden. This truncates the inner content element to the height of the wrapping div. when the user clicks, hovers, etc. to show the full height of the content element - simply animate the wrapping div to the height of the inner content div.

I could suggest an equally-hackish solution...Clone the element, position it out of view, and get its height...then delete it and animate your original.
That aside, you could also use $.slideUp() and $.slideDown():
$this.hasClass('closed') ? $(this).slideDown() : $(this).slideUp() ;
If you need to keep a 1px line, you can apply that with a parent element:
<div style='border-top:1px solid #333333'>
<div class='toggleMe'>Hello World</div>
</div>
And apply the slidingUp/Down on the .toggleMe div.

I'd also like to chime in on this old thread, if I may, in case my solution helps anyone. My specific situation is this: I have some div's that are set with a max-height value that limits them to three lines tall, and when the user mouseovers them I want them to expand to their natural height; and when the mouse cursor leaves the div, I want them to shrink back down to the clipped, max-three-lines-tall height. I need to use the CSS max-height property, rather than height, because I have some div's that contain only one or two lines of text and I don't want them unnecessarily tall.
I tried many of the solutions in this thread, and the one that worked for me was the 'hackish suggestion' involving cloned elements suggested by Jonathan Sampson. I translated his idea into the following code. Please feel free to suggest improvements.
The functions are delegated to a parent element to handle div's created via an Ajax call. The div.overflow_expandable class has the following declaration: { max-height: 5em; overflow: hidden; }
$('#results').delegate('div.overflow_expandable', 'mouseenter', function() {
var $this = $(this);
// Close any other open divs
$('#results div.overflow_expandable').not($(this)).trigger('mouseleave');
// We need to convert the div's current natural height (which is less than
// or equal to its CSS max-height) to be a defined CSS 'height' property,
// which can then animate; and we unset max-height so that it doesn't
// prevent the div from growing taller.
if (!$this.data('originalHeight')) {
$this.data('originalHeight', $this.height());
$this.data('originalMaxHeight', parseInt($this.css('max-height')));
$this.css({ 'max-height':'none',
height: $this.data('originalHeight') });
}
// Now slide out if the div is at its original height
// (i.e. in 'closed' state) and if its original height was equal to
// its original 'max-height' (so when closed, it had overflow clipped)
if ($this.height() == $this.data('originalHeight') &&
$this.data('originalMaxHeight') == $this.data('originalHeight')) {
// To figure out the new height, clone the original element and set
// its height to auto, then measure the cloned element's new height;
// then animate our div to that height
var $clone = $this.clone().css({ height: 'auto', position: 'absolute',
zIndex: '-9999', left: '-9999px', width: $this.width() })
.appendTo($this);
$this.animate({ height: $clone.height() }, 'slow');
$clone.detach();
}
}).delegate('div.overflow_expandable', 'mouseleave', function() {
var $this = $(this);
// If the div has 'originalHeight' defined (it's been opened before) and
// if it's current height is greater than 'originalHeight' (it's open
// now), slide it back to its original height
if ($this.data('originalHeight') &&
$this.height() > $this.data('originalHeight'))
$this.animate({ height: $this.data('originalHeight') }, 'slow');
});

Found this post and end up using Greg's original 1px suggestion - works great!
Just added a callback to the animate function, to set the height of the element to 'auto' when the animation ends (in my case, the content of that specific element could change and be bigger).

$('div').click(function() {
if($('p').is(':hidden')) {
$('p').slideUp();
} else {
$('p').slideDown(function() { $('p').css('height','1px'); });
}
}
That should set the height of the p tags to be 1px once they've finished sliding.

This worked for me.
<div class="product-category">
<div class="category-name">
Cars
</div>
<div class="category-products" style="display: none; overflow: hidden;">
<div class="product">Red Car</div>
<div class="product">Green Car</div>
<div class="product">Yellow Car</div>
</div>
</div>
<script type="text/javascript">
$(document).ready(function() {
$('.product-category .category-name').click(function() {
if ($(this).parent().hasClass('active')) {
$(this).parent().removeClass('active');
var height = $(this).parent().find('.category-products').height();
$(this).parent().find('.category-products').animate({ height : '0px' }, 600, function() {
$(this).parent().find('.category-products').height(height).hide();
});
} else {
$(this).parent().addClass('active');
var height = $(this).parent().find('.category-products').height();
$(this).parent().find('.category-products').height(0).show().animate({ height : height + 'px' }, 600);
}
});
});
</script>

My solution is to store in the data attribute of the close button the original size of container (could have been stored also in the container itself, if you don't use the same button to also show again the container):
$(document).ready(function(){
$('.infoBox .closeBtn').toggle(hideBox, showBox);
});
function hideBox()
{
var parent = $(this).parent();
$(this).text('Show').data('originalHeight', parent.css('height'));
parent.animate({'height': 20});
return false;
}
function showBox()
{
var parent = $(this).parent();
$(this).text('Hide');
parent.animate({
'height': $(this).data('originalHeight')
});
return false;
}

I wanted to point to this answer, which suggest setting the height to "show" with the animate() function. I had to edit my "slideUp" style animate to use height:"hide" to work with it.
