jQuery add row number as class on the divs on current row

jQuery add row number as class on the divs on current row - javascript

I need to make jquery fill all the rows in a layout as the first row in the fiddle
not sure if I explained well enough but the fiddle should clear out what I want.
first five divs have width changed a bit to make sure the row is filled, but I can't make the rest of rows fill the container
basically I want to justify all the divs by increasing their widths
http://jsfiddle.net/SG9Vx/
so far I have this function, modified from here: jQuery Find number of items per row in floated li's:
var lisInRow = 0;
$('#posts div').each(function() {
if($(this).prev().length > 0) {
if($(this).position().top != $(this).prev().position().top) return false;
lisInRow++;
$(this).addClass("row1");
}
else {
lisInRow++;
$(this).addClass("row1");
}
});
var itemNumber = $(".row1").length
var widthRow = 0;
$('.row1').each(function() {
widthRow += $(this).outerWidth( true );
});
var widthContainer = $("#posts").width();
var remaining = widthContainer - widthRow;
leftMargin = Math.floor(remaining / itemNumber);
$(".row1").each(function(){
var addedwidth = $(this).width() + leftMargin;
$(this).width(addedwidth);
});
What I do for the first row is calculate what's left of the container, divide it by number of items on the row, and add the result to the width of each item on the row.

If I understood what you're trying to do, I made some small changes to the code
var lisInRow = 0;
var lisInRow2 = 0;
var row = 0;
$('div div').each(function() {
if($(this).prev().length > 0) {
if($(this).position().top != $(this).prev().position().top) row++;
lisInRow++;
$(this).addClass("row"+row);
//console.log($(this).prev().length)
}
else {
lisInRow++;
$(this).addClass("row0");
}
});
for(var i=0;i<=row;i++){
var itemNumber = $(".row"+i).length
console.log(row);
var widthRow = 0;
$(".row"+i).each(function() {
widthRow += $(this).outerWidth( true );
});
var widthContainer = $("#posts").width();
var remaining = widthContainer - widthRow;
leftMargin = Math.floor(remaining / itemNumber);
$(".row"+i).each(function(){
var addedwidth = $(this).width() + leftMargin;
$(this).width(addedwidth);
$(this).find("img").width(addedwidth);
});
}
Here you have it:
http://jsfiddle.net/SG9Vx/3/

Here's a simplified version of what I think you're trying to achieve:
var lisInRow = 0;
$('div div').each(function() {
if($(this).prev().length > 0) {
if($(this).position().top != $(this).prev().position().top){
lisInRow++;
}
$(this).addClass("row" + lisInRow);
}
});

jQuery - Each counting resetting issue

I'm trying to get the currentpage number using jQuery each function. This is how I am doing it
var CurrentPageView = 1;
var check = true;
var Bookmark = [];
var CurPage = 1;
$(function() {
$(window).scroll(function() {
if (check) {
var PagesPosition = [];
var CurrentWindowPosition = $(window).scrollTop();
var CurrentCenterWindowPos = CurrentWindowPosition + $(window).height() / 2;
$(".Page").each(function() {
var PagePos = $(this).offset().top;
if (PagePos / CurrentCenterWindowPos <= 1) {
CurPage = $(this).index() + 1;
}
});
$(".CurrPageNumber").val(CurPage);
CurrentPageView = CurPage;
}
});
});
And it is working pretty well. If i am scrolling up and down he changes and gives me the currentpage number. The problem happens if between those with the class page there is something like a span. When this happens the counter resets to 1..
I would like to know if there is a way to keep the counting working for every div with the class "A4 Portrait" even if inside a span.
So instead of the actual count
1
2
1
2
It would be
1
2
3
4

Try using the index in the list of .Page instead of the index in its parent:
$(".Page").each(function(i) {
var PagePos = $(this).offset().top;
if (PagePos / CurrentCenterWindowPos <= 1) {
CurPage = i + 1; // Use the index in the array.
}
});
$(".CurrPageNumber").val(CurPage);
CurrentPageView = CurPage;

horizontal timeline fixed distance and centered on mobile devices

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['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

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!

get interval ID from else statement when set in IF

I am attempting to create a responsive slider, that will change to a simple set of dot points when in mobile mode (< 940).
The issue I am facing is in my else statement I am unable to clearintervals that were made in the if statement, because t comes up as undefined. I have resorted to using
for (var i = 1; i < 99999; i++) window.clearInterval(i); to clear the interval which works, but I don't like it because it's ugly and cumbersome, is there another way of accomplishing this?
$(document).ready(function() {
function rePosition() {
//get responsive width
var container_width = $('.container').width();
//Slider for desktops only
if(container_width >= 940) {
//get variables
var slide_width = $('.slider_container').width();
var number_of_slides = $('.slider_container .slide').length;
var slider_width = slide_width*number_of_slides;
//set element dimensions
$('.slide').width(slide_width);
$('.slider').width(slider_width);
var n = 1;
var t = 0;
$('.slider_container').hover(function() {
clearInterval(t);
}, function() {
t = setInterval(sliderLoop,6000);
});
var marginSize = i = 1;
//Called in Doc Load
function sliderLoop(trans_speed) {
if (trans_speed) {
var trans_speed = trans_speed;
}
else
{
var trans_speed = 3000;
}
if (i < number_of_slides) {
marginSize = -(slide_width * i++);
}
else
{
marginSize = i = 1;
}
$('.slider').animate({ marginLeft: marginSize }, trans_speed);
}
t = setInterval(sliderLoop,6000);
$('.items li').hover(function() {
$('.slider').stop();
clearInterval(t);
var item_numb = $(this).index();
i = item_numb;
sliderLoop(500);
}, function() {
t = setInterval(sliderLoop,6000);
});
}
else
{
for (var i = 1; i < 99999; i++)
window.clearInterval(i);
$('.slider').stop(true, true);
$('.slider').css('margin-left', '0px');
//rearrange content
if($('.slider .slide .slide_title').length < 1) {
$('.items ul li').each(function() {
var item_numb = $(this).index();
var content = $(this).text();
$('.slider .slide:eq(' + item_numb + ')').prepend('<div class="title slide_title">' + content + '</div>')
});
}
}
}
rePosition();
$(window).resize(function() {
rePosition();
});
});

Teemu's comment is correct. I'll expand on it. Make an array available to all of the relevant code (just remember that globals are bad).
$(document).ready(function() {
var myIntervalArray = [];
Now, whenever you create an interval you will need to reference later, do this:
var t = setInterval();//etc
myIntervalArray.push(t); //or just put the interval directly in.
Then to clear them, just loop the array and clear each interval.
for (var i=0; i<myIntervalArray.length; i++)
clearInterval(myIntervalArray[i]);
}

Umm, wouldn't t only be defined when the if part ran... as far as I can tell, this is going to run and be done... the scope will be destroyed. If you need to maintain the scope across calls, you'll need to move your var statements outside of reposition(), like so:
$(document).ready(function() {
var t = 0;
...
function rePosition() { ... }
});

Responsive jQuery menu, collapsing last elements into separate menu

I have a single level navigation list. What I want to do is, on window resize, add a dropdown at the end to display elements that do not fit the window width.
Below an image representation:
var base = this,
container = $(base.selector),
items = container.find('>li:not(.smallmenu):visible'),
count = container.find('>li:not(.smallmenu):visible').length,
listWidth = [],
added;
items.each(function() {
listWidth.push($(this).width());
});
function getWidth() {
var width = 0;
container.find('>li:not(.smallmenu):visible').each(function() {
width += $(this).outerWidth();
});
return width + 100;
}
function hideLast() {
var i = container.find('>li:not(.smallmenu):visible').last().index()
if( $(window).width() < (getWidth()) ) {
items.eq(i).hide();
if(!added) {
$('<li class="smallmenu"><i class="fa fa-plus"></i></li>').appendTo(container);
added = true;
}
}
}
function showLast() {
var i = container.find('>li:not(.smallmenu):visible').last().index();
if( (getWidth() + listWidth[i+1]) < $(window).width() ) {
container.find('>li:not(.smallmenu)').eq(i+1).show();
if((i+2) === count) {
container.find('.smallmenu').remove();
added = false;
}
}
}
$(window).resize(function() {
showLast();
hideLast();
});
However this is not working as expected and half-done. I feel like I am heading in the wrong direction.
EDIT: Here is an updated jsFiddle: http://jsfiddle.net/anteksiler/zyv8f/1/ Resize your browser to get the effect.

Split a big ul list

I have a big ul list. With a lot of li items. I want split this big list in parts of 10. I make a script, but the script is not working. What do i wrong:
var maxItems = 10;
var ul = $('.list-thumbnails');
var current;
ul.find('li').each(function(i, el) {
  if (i < maxItems) {
    // leave first 10 in the original list
    return;
  }
  if (i % maxItems == 0) {
    current =
        $(el)
            .closest('ul')
            .clone()
            .after($(el).closest('ul'));
  }
.append(current);
});

I have modified the code block as below. Please check it
Since your looping the $.each though you use append method it won't get reflected in the ul and so we need to remove the element.
var maxItems = 10;
var ul = $('.list-thumbnails');
var currentul;
var elements = ul.find('li');
elements.each(function (i, el) {
if (i < maxItems) {
// leave first 10 in the original list
return;
}
if (i % maxItems == 0) {
currentul = $("<ul></ul>").addClass("new");
$(el).closest('ul').parent().append((currentul.append(el)));
}
else {
currentul.append(el)
}
});
$('.list-thumbnails').find("li:gt(9)").remove();
Please check the below jsfiddle
