Showing multiple sticky header while scroll down the webpage

Showing multiple sticky header while scroll down the webpage - javascript

I am a beginner in jQuery. As willing to develop a mobile website, I would like to implement sticky header for enhancing the user experiences.
Here are some codes of my work but it seems not work as calculation of the "top".
HTML:
<div class="fixed-header">
<div class="header_item" id="head_a"> A </div>
<div class="header_item" id="head_b"> B </div>
<div class="header_item" id="head_c"> C </div>
<div class="header_item" id="head_d"> D </div>
<div class="header_item" id="head_e"> E </div>
</div>
javascript and jQuery:
var $totalImageHeight;
$(window).on("load", function() { //Fires when DOM is loaded
getImageSizes();
$(window).resize(function() { //Fires when window is resized
getImageSizes();
});
});
function getImageSizes() {
$(".insurance_item img").each(function(count) {
var $this = $(this);
$imageHeight = $this.height();
$totalImageHeight = $imageHeight * (count + 1);
});
}
var stickyHeaders = (function() {
var $window = $(window),
$stickies;
var load = function(stickies) {
if (typeof stickies === "object" && stickies instanceof jQuery && stickies.length > 0) {
$stickies = stickies.each(function() {
var $thisSticky = $(this).wrap('<div class="followWrap" style="height: 0;"/>');
$thisSticky
.data('originalPosition', $thisSticky.offset().top)
.data('originalHeight', $thisSticky.outerHeight( 75 ))
.parent().height($thisSticky.outerHeight( 75 ));
});
$window.off("scroll.stickies").on("scroll.stickies", function() {
_whenScrolling();
});
}
};
var _whenScrolling = function() {
$stickies.each(function(i) {
var $thisSticky = $(this),
$stickyPosition = $thisSticky.data('originalPosition');
if ($stickyPosition <= $window.scrollTop()) {
var $nextSticky = $stickies.eq(i + 1);
$nextStickyPosition = $totalImageHeight - $nextSticky.data('originalPosition') - $thisSticky.data('originalHeight');
$thisSticky.addClass("fixed").css("top", $nextStickyPosition);
if ($nextSticky.length > 0 && $thisSticky.offset().top >= $nextStickyPosition) {
$thisSticky.addClass("absolute").css("top", $nextStickyPosition);
}
}else{ //scroll up and disable the fixed header
var $prevSticky = $stickies.eq(i - 1);
$thisSticky.removeClass("fixed");
if($prevSticky.length>0&&$window.scrollTop()<=
$thisSticky.data('originalPosition') -
$thisSticky.data('originalHeight')){
$prevSticky.removeClass("absolute").removeAttr("style");
}
}
});
};
return {
load: load
};
})();
$(function() {
stickyHeaders.load($(".header_item"));
});

Sorry for the late answer. I create an new javascript for implementing this function.
Code:
var $window = $(window);
var imageArr = [];
var iOS = !!navigator.platform && /iPad|iPhone|iPod/.test(navigator.platform);
console.log(iOS);
$(window).on("load", function() { //Fires when DOM is loaded
getImageSizes();
window.requestAnimationFrame(tick);
$(window).resize(function() { //Fires when window is resized
getImageSizes();
scrollDetect(imageArr);
});
});
function getImageSizes() { //get the numbers of images and its outerHeight
var $items = $(".insurance_item");
for(var c = 0; c < $items.length; c++){
imageArr[c] = $($items[c]).outerHeight();
}
}
function scrollDetect(imageArr){ //show the title header of image once the image is offscreen.
var $items = $('.header_item');
for(var c = 0; c < imageArr.length; c++){
if($window.scrollTop() >= (imageArr[c] * (c+1)) - $('#fixed-header').outerHeight()){
$items.eq(c).show();
}else{
$items.eq(c).hide();
}
}
window.requestAnimationFrame(tick); //prevent the frame lost and make a incorrect calculation
}
function tick(){
scrollDetect(imageArr);
};
May be some better solution for solving this situation, thanks for everyone.

Wordpress: Homepage js is conflicting with js of plugin of portfolio page

I've downloaded Awesome Filterable Portfolio plugin , It was working fine.. but when I added a js file for scrolling carousel on home page, The js of that plugin stoped working..
I've added my cr-scroll.js file in functions.php as given below:
wp_register_script('java1', get_template_directory_uri() . '/js/cr-scroll.js', array( 'jquery' ));
wp_enqueue_script( 'java1' );
What I've Tried:
$.noConflict();
Replaced $ with jquery
Wrap the code in
(function($){
$(document).ready(function(){
});
})(jQuery);
but nothing worked.
My js file is cr-scroll.js:
(function($){
$(document).ready(function($) {
$.fn.make_carousel = function() {
var speed = 0;
var scroll = 0;
var con = $(this);
var con_w = con.width();
var max_scroll = con[0].scrollWidth - con.outerWidth();
var prev_frame = new Date().getTime();
con.on('mousemove', function(e) {
var mouse_x = e.pageX - con.offset().left;
var mouseperc = 100 * mouse_x / con_w;
speed = mouseperc - 50;
}).on ( 'mouseleave', function() {
speed = 0;});
function updatescroll() {
var cur_frame = new Date().getTime();
var time_elapsed = cur_frame - prev_frame;
prev_frame = cur_frame;
if (speed !== 0) {
scroll += speed * time_elapsed / 50;
if (scroll < 0) scroll = 0;
if (scroll > max_scroll) scroll = max_scroll;
con.scrollLeft(scroll);
}
window.requestAnimationFrame(updatescroll);
}
window.requestAnimationFrame(updatescroll);
}
$("#carousel1").make_carousel();
$("#carousel2").make_carousel();
function reset(){
$('.maincontent').find('*').removeAttr('class');
document.getElementById('step1').setAttribute("class", "visible");
}
function back(){
var previous_class = $('.visible').data('previous');
if(previous_class != ''){
var current_class = $('.visible').attr('id');
document.getElementById(current_class).setAttribute("class","");
document.getElementById(previous_class).setAttribute("class","visible");
}
}
function show_next(current,next) {
document.getElementById(current).setAttribute("class", "hidden");
document.getElementById(next).setAttribute("class", "visible");
}
function show_hide(show_ele,hide_ele) {
document.getElementById(show_ele).style.display = "block";
document.getElementById(hide_ele).style.display = "none";
}
function load_after_sec(id) {
count = 0;
wordsArray = ["5", "4", "3", "2", "1"];
var timerID = setInterval(function () {
count++;
if(count == 5){
$("#"+id).show();
$("#seconds_counter").hide();
clearInterval(timerID);
} else {
$("#num_sec").fadeOut(400, function () {
$(this).text(wordsArray[count % wordsArray.length]).fadeIn(400);
});
}
}, 2000);
}
function showButton(){
document.getElementById("btn_repeat").style.display='block';
}
});
})(jQuery);
In home page go to portfolio section, it is scrolling because of js, and after clicking on visit portfolio button, you'll be redirected to portfolio page and the filters of portfolio is not clickable and changeable because of js confliction.
The console gives an error for that cr-scroll.js file that con[0] is undefined.
If I remove this file then plugin works fine, why it is conflicting?
Any help will be appreciated, Thank you in advance.

Unable to combine functions in to one file

I have two functions, one to show a gallery of images and one for a smooth scroll up icon. The problem is when I use them separately, both of them works. But when I put them in the same file only the first one works. I can t figure out the problem. I am using jquery-2.0.3
Here is my Code:
$(function() {
$('.demo li').picEyes();
// Caching the Scroll Top Element
// console.log("function move to top");
var ScrollButton = $("#scroll");
$(window).scroll(function() {
// console.log($(this).scrollTop());
if ($(this).scrollTop() >= 50) {
ScrollButton.show()
} else {
ScrollButton.hide();
}
});
// Click On Button To Scroll To Top Of The Page
ScrollButton.click(function() {
$("html,body").animate({
scrollTop: 0
}, 800);
});
});
the code of picEyes function:
(function($){
$.fn.picEyes = function(){
var $obj = this;
var num,zg = $obj.length - 1;
var win_w = $(window).width();
var win_h = $(window).height();
var eyeHtml = '<div class="picshade"></div>'
+'<a class="pictures_eyes_close" href="javascript:;"></a>'
+'<div class="pictures_eyes">'
+'<div class="pictures_eyes_in">'
+'<img src="" />'
+'<div class="next"></div>'
+'<div class="prev"></div>'
+'</div>'
+'</div>'
+'<div class="pictures_eyes_indicators"></div>';
$('body').append(eyeHtml);
$obj.click(function() {
$(".picshade").css("height", win_h);
var n = $(this).find("img").attr('src');
$(".pictures_eyes img").attr("src", n);
num = $obj.index(this);
popwin($('.pictures_eyes'));
});
$(".pictures_eyes_close,.picshade,.pictures_eyes").click(function() {
$(".picshade,.pictures_eyes,.pictures_eyes_close,.pictures_eyes_indicators").fadeOut();
$('body').css({'overflow':'auto'});
});
$('.pictures_eyes img').click(function(e){
stopPropagation(e);
});
$(".next").click(function(e){
if(num < zg){
num++;
}else{
num = 0;
}
var xx = $obj.eq(num).find('img').attr("src");
$(".pictures_eyes img").attr("src", xx);
stopPropagation(e);
popwin($('.pictures_eyes'));
});
$(".prev").click(function(e){
if(num > 0){
num--;
}else{
num = zg;
}
var xx = $obj.eq(num).find('img').attr("src");
$(".pictures_eyes img").attr("src", xx);
stopPropagation(e);
popwin($('.pictures_eyes'));
});
function popwin(obj){
$('body').css({'overflow':'hidden'});
var Pwidth = obj.width();
var Pheight = obj.height();
obj.css({left:(win_w - Pwidth)/2,top:(win_h - Pheight)/2}).show();
$('.picshade,.pictures_eyes_close').fadeIn();
indicatorsList();
}
function updatePlace(obj){
var Pwidth = obj.width();
var Pheight = obj.height();
obj.css({left:(win_w - Pwidth)/2,top:(win_h - Pheight)/2});
}
function indicatorsList(){
var indHtml = '';
$obj.each(function(){
var img = $(this).find('img').attr('src');
indHtml +='<img src="'+img+'"/>';
});
$('.pictures_eyes_indicators').html(indHtml).fadeIn();
$('.pictures_eyes_indicators a').eq(num).addClass('current').siblings().removeClass('current');
$('.pictures_eyes_indicators a').click(function(){
$(this).addClass('current').siblings().removeClass('current');
var xx = $(this).find('img').attr("src");
$(".pictures_eyes img").attr("src", xx);
updatePlace($('.pictures_eyes'));
});
}
function stopPropagation(e) {
e = e || window.event;
if(e.stopPropagation) {
e.stopPropagation();
} else {
e.cancelBubble = true;
}
}
}
})(jQuery);

You should add click event handler, when DOM will be ready, do like this:-
$(function () {
$('.demo li').picEyes();
// Caching the Scroll Top Element
// console.log("function move to top");
//var ScrollButton =ScrollButton.click
var ScrollButton = $("#scroll")
$(window).scroll(function () {
// console.log($(this).scrollTop());
if ($(this).scrollTop() >= 50) {
ScrollButton.show()
} else {
ScrollButton.hide();
}
});
// Click On Button To Scroll To Top Of The Page
ScrollButton.click(function () {
$("html,body").animate({
scrollTop: 0
}, 800);
});
});

I bet both scripts have own ScrollButton element, and while gallery is loaded it owerwrites behaviour of other ScrollButton element.

I put the call of picEyes function outside of the main function and somehow worked !

How to dynamically add elements via jQuery

The script below creates a slider widget the takes a definition list and turns it into a slide deck. Each dt element is rotated via css to become the "spine", which is used to reveal that dt's sibling dd element.
What I'm trying to do is to enhance it so that I can have the option to remove the spines from the layout and just use forward and back buttons on either side of the slide deck. To do that, I set the dt's to display:none via CSS and use the code under the "Remove spine layout" comment to test for visible.
This works fine to remove the spines, now I need to dynamically create 2 absolutely positioned divs to hold the left and right arrow images, as well as attach a click handler to them.
My first problem is that my attempt to create the divs is not working.
Any help much appreciated.

Creating elements in jQuery is easy:
$newDiv = $('<div />');
$newDiv.css({
'position': 'absolute',
'top': '10px',
'left': '10px'
});
$newDiv.on('click', function() {
alert('You have clicked me');
});
$('#your_container').append($newDiv);

How to smoothly scroll a browser window using hashes with a fixed element on top?

I have a website that has a fixed navigation bar at the top that contains links to achors in the rest of the content like so:
<header style="position:fixed">
Scroll to Headline Hello
</header>
<article>
<h1><a name="hello" id="hello">Hello</a><h1>
</article>
When someone clicks on the link, the corresponding headline is obscured by the header, because the browser positions it directly at the beginning of the viewport. I tried to use the csstricks' jQuery-script described here http://css-tricks.com/snippets/jquery/smooth-scrolling/ to smootly scroll to a targetOffset + heightOfHeader but that just makes the content jump randomly up and down.
Here is the script:
$(document).ready(function() {
function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}
var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body');
$('a[href*=#]').each(function() {
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top;
$(this).click(function(event) {
event.preventDefault();
$(scrollElem).animate({scrollTop: targetOffset}, 400, function() {
location.hash = target;
});
});
}
}
});
// use the first element that is "scrollable"
function scrollableElement(els) {
for (var i = 0, argLength = arguments.length; i <argLength; i++) {
var el = arguments[i],
$scrollElement = $(el);
if ($scrollElement.scrollTop()> 0) {
return el;
} else {
$scrollElement.scrollTop(1);
var isScrollable = $scrollElement.scrollTop()> 0;
$scrollElement.scrollTop(0);
if (isScrollable) {
return el;
}
}
}
return [];
}
});
Any help would be appreciated.

I see that you're tagging the question with jquery. I like to use scrollTo plugin to accomplish this.
