I am trying to reach a horizontal timeline like this:
https://codepen.io/ritz078/pen/LGRWjE
My problem is, that I've got no real dates (DD/MM/YYYY) but only years like 1998-2002 or just 2009. So there is a problem, I am struggling to fix, which ends up like this:
So my aims are:
Set a fixed distance between elements
Make it work just with years
When on a device less than 768px wide ensure a single element is displayed and it appears in the center
This is my solution for 3., but the other things, I couldnt solute:
if ($(window).width() < 768 {
eventsMinDistance = $('.cd-horizontal-timeline .events-wrapper').width(/2;)
}
(timelines.length > 0) && initTimeline(timelines);
$(window).resize(function(){
if ($(window).width() < 768 {
eventsMinDistance = $('.cd-horizontal-timeline .events-wrapper').width(/2;)
} else{
eventsMinDistance = 155;
}
}
Do you guys know how do adjust it, as I am struggling since hours without any success. Thank you very much for your help!
the first part of your code works fine, but it was faulty on the syntax, I fixed it and use it and also add a couple of changes to acomplished the desired fixed width amount between each date.
Actually it was pretty easy, when you debug and you know exactly what the developer wants to do.
This is the code I wrote:
jQuery(document).ready(function($){
var timelines = $('.cd-horizontal-timeline'),
eventsRelativeDistance = false;
if ($(window).width() < 768) {
eventsMinDistance = Number($('.cd-horizontal-timeline .events-wrapper').width())/2;
}else{
var eventsMinDistance = 100;
}
(timelines.length > 0) && initTimeline(timelines);
$(window).resize( function(){
if ($(window).width() < 768) {
eventsMinDistance = Number($('.cd-horizontal-timeline .events-wrapper').width())/2;
} else{
eventsMinDistance = 100;
}
});
function initTimeline(timelines) {
timelines.each(function(){
var timeline = $(this),
timelineComponents = {};
//cache timeline components
timelineComponents['timelineWrapper'] = timeline.find('.events-wrapper');
timelineComponents['eventsWrapper'] = timelineComponents['timelineWrapper'].children('.events');

timelineComponents['eventsMinLapse'] = minLapse(timelineComponents['timelineDates']);
timelineComponents['timelineNavigation'] = timeline.find('.cd-timeline-navigation');
timelineComponents['eventsContent'] = timeline.children('.events-content');
if(!eventsRelativeDistance){
// Set up space to store the distance in pixels.
timelineComponents['distanceInPx'] = [];
}
//assign a left postion to the single events along the timeline
setDatePosition(timelineComponents, eventsMinDistance, eventsRelativeDistance);
//assign a width to the timeline
var timelineTotWidth = setTimelineWidth(timelineComponents, eventsMinDistance, eventsRelativeDistance);
//the timeline has been initialize - show it
timeline.addClass('loaded');

Did you ever get this to work?? Have come across the same problem. If i change the default distance from 60 to 1 the gap between is not enough and the whole timeline breaks. The calculations for the distance as described in the article is as follows
First of all, in the main.js file, we set a minimum distance between two consecutive dates, using the eventsMinDistance variable; in our case, we set eventsMinDistance = 60 (so the minimum distance will be 60px). Then we evaluate all the differences between a date and the following one; to do that we use the data-date attribute added to each date. The minimum difference is then used as a reference to evaluate the distances between two consecutive dates.
For example, let's suppose the minimum found difference is 5 days; that means that the distance, along the timeline, between two dates separated by a lapse of 5days will be 60px, while the one between two events separated by a lapse of 10 days will be 120px.
source:: www.codyhouse.org
From what i read the min distance is here:~
var timelines = $('.cd-horizontal-timeline'),
eventsMinDistance = 60;
(timelines.length > 0) && initTimeline(timelines);
This creates a variable called timelines and sets it to the class .cd-hor... and sets the min distance to 60px. changing this to 1 breaks the application as the distance between the times are too small.
function setDatePosition(timelineComponents, min) {
for (i = 0; i < timelineComponents['timelineDates'].length; i++) {
var distance = daydiff(timelineComponents['timelineDates'][0], timelineComponents['timelineDates'][i]),
distanceNorm = Math.round(distance/timelineComponents['eventsMinLapse']) + 2;
timelineComponents['timelineEvents'].eq(i).css('left', distanceNorm*min+'px');
}
}
I might be wrong but here is the section calculating the distance and the last distanceNorm*min+'px'. min i believe is 60 and distance norm is the calculation of the 5 days etc. if you remove distance norm the app breaks so you cant just add min+'px' this is because you remove the original distance.
All distances are calculated from the first timeline. Thats why the app breaks. Need to find the code that tells which to calc from which is the
var distance = daydiff(timelineComponents['timelineDates'][0], timelineComponents['timelineDates'][i]),
distanceNorm = Math.round(distance/timelineComponents['eventsMinLapse']) + 2;
this sets distance as the first element of the index and then for each timelineDates within the loop [i].
I've been at it for days but have come to the conclusion the tutorial is good as is but it is not a library and should be used as reference to write your own from scratch which is what i am now doing.
If you did ever manage it though please update as so far i managed to manipulate the dates to get equal spacing but if you insert too many it breaks which is no good hence the rewrite!
I have a paragraph tag in my html id is move, I am trying to move the p tag to slowing fall down while on page load. but my code is not working.......
var speed = 12;
var direction = 1;
var getParagraph = document.getElementById("move");
getParagraph.onmouseover = moving;
function moving() {
var bo = getParagraph.offsetHeight;
var boTop = getParagraph.offsetTop;
var boBottom = boTop + bo;
// When right side of the box goes too far - change direction:
if (boBottom > document.body.offsetHeight) {
direction = -1;
}
// When left side of the box goes too far - change direction:
if (boTop < 0) {
direction = 1;
}
// Recalculate position:
getParagraph.style.Top = (boTop + speed * direction)
}
This is your code with minor changes, and it "works":
JS:
var speed = 12;
var direction = 1;
var getParagraph = document.getElementById("move");
document.getElementById("move").addEventListener("mouseover", moving);
//getParagraph.onmouseover = moving;
function moving() {
console.log("Moving??");
var bo = document.getElementById("move").offsetHeight;
var boTop = document.getElementById("move").offsetTop;
var boBottom = boTop + bo;
// When right side of the box goes too far - change direction:
if (boBottom > document.body.offsetHeight) {
direction = -1;
}
// When left side of the box goes too far - change direction:
if (boTop < 0) {
direction = 1;
}
// Recalculate position:
document.getElementById("move").style.marginTop = (boTop + speed * direction) + "px";
speed++;
}
CSS:
#move {
display : block ;
position : absolute ;
}
Hope it helps.

I am trying to animate my website falling apart but I am having a hard time articulation this into code. I thought of running the animation in a loop, creating events at specific frames and reusing some codes as functions. I have a rotate function which works to rotate several things.
THE PROBLEM:
The problem I am having is sliding my menu items one at a time to the right. I want one to slide a bit and the next to start sliding after. I wrote a function to slide an item and then in that function it adds another process to an array for the next menu item to be called and run the same function (with passed interval of who is calling). I do not know how many menu items there will be, thats why I am trying to make it dynamic.
I can get it so that the first mwnu item falls, the menu falls by rotating it (some times if there is an error in the code then it wont rotate, but when there are no errors it works better).
The issue is sliding each menu item.
my website is here: http://clearlove.ca/89-404-error
Can any one help me with why this isnt working, and if there is a better way to do what I am trying to do?
I install Float Left Right Advertising plugin on my site: www.displej.me and I set banners at the side of site.

is something I would try to keep the sides free from the centered divs movements.
I'm making a scheduling calendar. The events are horizontal blocks (Google Cal has vertical ones). And because I have loads of events in one date I want the events to stack onto eachother without wasting any space, like this:
I did find plugins:
http://masonry.desandro.com/
http://isotope.metafizzy.co/
http://packery.metafizzy.co/
But I'm not keen on using a 30kb plugin just to do this simple thing.
To clarify: because this is a timeline, the div-events cannot move left/right, but must fit itself vertically amongst other div-events.
My own solution is a 2.6kb (commented) jQuery script, that uses absolute positioning for events and a div as a container for each row.
This script generates randomly size bars. Each new bar checks for space in each row from top-down. I'm using percentages, because that way calculating bar position against time will be easy (100% / 24h).

Though works and is efficient enough, it feels bulky. You're welcome to improve.
jQuery code from my jsfiddle:
function rand() {
return Math.floor(Math.random() * 101);
}
function get_target_row(width, left) {
var i = 0;
var target_found = false;
// Loop through all the rows to see if there's space anywhere
while (target_found === false) {
// Define current row selector
var target_i = '.personnel#row' + i;
// Add row if none
if ($(target_i).length === 0) {
$('body').append('<div class="personnel" id="row' + i + '"></div>');
}
// See if there's space
if ($(target_i).children().length === 0) {
target_found = $(target_i);
} else {
var spaceFree = false;
// Check collision for each child
$(target_i).children().each(function () {
// Get left and right coordinates
var thisWidthPx = parseFloat($(this).css('width'), 10);
var thisWidthParentPx = parseFloat($(this).parent().css('width'), 10);
var thisWidth = (thisWidthPx / thisWidthParentPx * 100);
var thisLeftPx = parseFloat($(this).css('left'), 10);
var thisLeftParentPx = parseFloat($(this).parent().css('left'), 10);
var thisLeft = (thisLeftPx / thisWidthParentPx * 100);
var thisRight = thisLeft + thisWidth;
var right = left + width;
// Sexy way for checking collision
if ((right > thisLeft && right < thisRight) || (left < thisRight && left > thisLeft) || (thisLeft > left && thisLeft < right) || (thisRight < right && thisRight > left)) {
spaceFree = false;
return false;
} else {
spaceFree = true;
}
});
// If no children have collided break the loop
if (spaceFree === true) {
target_found = $(target_i);
}
}
i++;
}
// If after all the while loops target is still not found...
if (target_found === false) {
return false;
}
// Else, if target is found, return it.
return target_found;
}
// Generate random bars
for (var i = 0; i < 10; i++) {
var width = rand()/2;
var left = rand()/2;
var right = left + width;
var target = get_target_row(width, left);
target.append('<div class="block" style="width:' + width + '%;position:absolute;left:' + left + '%;background-color:rgba(' + rand() + ',' + rand() + ',' + rand() + ',0.4)" id="bar'+i+'">' + 'b' + i + '</div>');
}
CSS:
.block {
position: absolute;
background-color: rgba(200, 100, 100, 0.4);
height: 32px;
}
.personnel {
position: relative;
float: left;
width: 100%;
height: 33px;
}
