I have the following layout in html:
<button>Hide first column</button>
<div class="row">
<div class="col-lg-1" id="left">Stuff</div>
<div class="col-lg-8" id="middle">Main Middle</div>
<div class="col-lg-3">1 + 8 + 3 is 12 right?</div>
</div>
With the following JS/jQuery:
$(document).ready(function() {
$('button').click(function() {
$('#left').toggleClass('hidden');
if ($("#left").hasClass('hidden')) {
$("#middle").removeClass('col-lg-8');
$("#middle").addClass('col-lg-9');
}
else {
$("#middle").removeClass('col-lg-9');
$("#middle").addClass('col-lg-8');
}
});
});
As you can see essentially I'm removing the left column and widening out the middle ( I may eventually widen out the right as well).
Is there anyway to animate these changes as opposed to having them suddenly occur? I'm thinking something along the columns sliding to fill the space.
Here's the bootply: http://www.bootply.com/MWz4O7khWq
Thanks
I'm not working with bootstrap but with this you should get the idea:
$(document).ready(function () {
originalwidth = $('#left').width();
$('button').click(function () {
if ($('#left').width() > 0) {
$('#left').animate({
width: "0"
}, 500);
}
else {
$('#left').animate({
width: originalwidth
}, 500);
}
});
});
.table {
display: table;
width: 500px;
table-layout: fixed;
}
.row {
display: table-row;
}
.row div {
display: table-cell;
border: 1px solid red;
overflow: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button>Hide first column</button>
<div class="table">
<div class="row">
<div class="col-lg-1" id="left">Stuff</div>
<div class="col-lg-8" id="middle">Main Middle</div>
<div class="col-lg-3">1 + 8 + 3 is 12 right?</div>
</div>
</div>

I have multiple divs with the same class (.item) and trying to figure out how to independently toggle between 2 divs (#open and #close).
For example, clicking on "A" or "B" toggles between "Open" and "Close" independently.
I've tried placing "(this)" before (.item), but it results in toggling not working at all.
$(this).on("click", function(event) {
$(event.target).closest(".item").toggleClass("highlight").toggleClass("marked unmarked");
if ($(".item").hasClass('unmarked')) {
$("#open").show();
$("#close").hide();
} else if ($(".item").hasClass('marked')) {
$("#close").show();
$("#open").hide();
} else {
$("#close").hide();
$("#open").hide();
}
});
.item {
text-align: center;
margin: 5px;
padding: 5px;
background: #EEEEEE;
}
.highlight {
background: orange;
}
#open,
#close {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="item marked">A</div>
<div class="item marked">B</div>
<div class="item marked">C</div>
<div id="open">Open</div>
<div id="close">Close</div>
Are you maybe looking for this behaviour?..
$('.item').on('click', function() {
if ($(this).hasClass('highlight')) {
$(this).removeClass('highlight');
$('#open').hide();
$('#close').show();
} else {
$('.item.highlight').removeClass('highlight');
$(this).addClass('highlight');
$('#open').show();
$('#close').hide();
}
})
.item {text-align: center;margin: 5px;padding: 5px;background: #EEEEEE;}
.highlight {background: orange;}
#open, #close {display: none;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="item">A</div>
<div class="item">B</div>
<div class="item">C</div>
<div id="open">Open</div>
<div id="close">Close</div>

Assuming I'm understanding your question correctly
My recommendation for this scenario is not to rely on the "this" keyword. $(this).on('click'.... is ridiculously broad. It needs to be contained in other code that would allow for a 'this' to be relative.
Instead, get your element by
var my_elemens = getElementsByClassName('item')
and refer to them by
my_elemens[0] // A
my_elemens[1] // B
my_elemens[2] // C
And then for whatever you're wanting to click, use it, so possibly...
$(myelemens[0]).on('click'....
I am making a page where there should be content on the left side and commercials in divs on the right side. The height of the left sides div is unknown. I want to add as many commercial divs as possible on the right side without making the height of the right side taller than the left side.
I have set the right sides div height equal to left sides height and then I have added overflow: hidden on the right sides div so that the commercial divs are being cut off. I don't want my commercial divs to be cut off so I would like to remove the one that is being cut off.
Here is my code https://jsfiddle.net/p9dmzoa3/
You can try below code, this will remove all those commercials DIV, which are getting cut-off :
$(document).ready(function() {
$(".right_side").css("height", $(".left_side").height());
$commercialDivs = $(".right_side").children("div.commercials");
$rightSideDivHeight = $(".right_side").height();
$tempHeight = 0;
for(var i=0;i<$commercialDivs.length;i++){
$tempHeight += $commercialDivs[i].clientHeight;
if($tempHeight>$rightSideDivHeight){
$commercialDivs[i].remove();
}
}
});
Something like this should do the thing.
$(document).ready(function() {
$(".right_side").css("height", $(".left_side").height());
var j = $(".right_side").children("div").length;
for (var i = 1; i < j; i++) {
if ((($('.right_side').offset().top + $(".right_side").height()) - ($('.right_side div:last-child').offset().top + $(".right_side div:last-child").height())) < 0) {
$(".right_side div:last-child").remove();
} else {
break;
}
}
});
div.left_side {
display: inline-block;
}
div.right_side {
display: inline-block;
float: right;
overflow: hidden;
}
div.left_side_content {
height: 30px;
margin-top: 10px;
background-color: green;
}
div.commercials {
height: 50px;
margin-top: 10px;
background-color: forestgreen;

Please, help me to configure my slider.
If you click on numbers in any row, you can see, that jquery give them classes and spin slider to index()
I want to add arrows to my slider, and do infinite loop. Eg if number 2 selected right arrow moves all 3 rows to number 3. And vice versa.
Here is my code.
$('.item').click(function() {
$this = $(this);
$(".item").removeClass("active");
$('.item').each(function() {
if (+$(this).index() == +$this.index()) {
$(this).addClass('active');
var box = $(this).closest('.scroll');
var x = ($(this).position().left - (box.width() / 2)) + box.scrollLeft();
box.animate({
scrollLeft: x
});
}
});
});

Added to your function to support all of what you want. Let me know if this helps! Added comments to areas I changed to explain what I am doing. I also made $this a local variable instead of a global as well by defining it with var.
Fiddle: http://jsfiddle.net/AtheistP3ace/3ewguuyL/
JS:
// Attach click to all clickable elements
$('.item, .left-arrow, .right-arrow').click(function () {
var $this = $(this);
// check if we clicked an item or arrow
if (!$this.hasClass('item')) {
// if left arrow, get previous item of first active we find
if ($this.hasClass('left-arrow')) {
$this = $('.item.active:first').prev();
}
// if right arrow, get next item of first active we find
else if ($this.hasClass('right-arrow')) {
$this = $('.item.active:first').next();
}
// Handle being at the start or end of items
if ($this.length == 0) {
return;
}
}
// Let your previous code run
$(".item").removeClass("active");
$('.item').each(function () {
if (+$(this).index() == +$this.index()) {
$(this).addClass('active');
var box = $(this).closest('.scroll');
var x = ($(this).position().left - (box.width() / 2)) + box.scrollLeft();
box.animate({
scrollLeft: x
});
}
});
});
Have a look at https://jsfiddle.net/0m0raekm/
For the arrow support I just added this part:
$('.arrow-control').click(function(){
var direction = $(this).hasClass('left-arrow') ? -1 : 1;
var currentItemIndex = $('.anywrap .active').index();
var itemCount = $('.anywrap .item').length;
var nextItemIndex = (currentItemIndex + direction)%itemCount;
var nextItem = $('.anywrap .item').get( nextItemIndex );
$(nextItem).trigger( "click" );
});
It is quite generic: it determines the currently active item, chooses the next one depending on the arrow direction and the number of items (infinite loops) and triggers a click event on the item that is supposed to be next. So after determining the next item, it uses your original code to do the actual effect.
I have some code that is meant to allow a user to scroll sideways by clicking, which works perfectly on jsfiddle, but does something completely different on my actual website. On my website, you can scroll right once but no further, and when you scroll back, it apparently scrolls right past the left-hand border.
Here's a live link to the problem on my website: rouvou.com/error
And here's the fiddle.
I literally copied and pasted the code. I'm using jQuery 1.10.0 on my website and the closest jQuery version jsfiddle has is 1.10.1, but I can't imagine that could cause this different behavior. The html I posted is the only code on that entire page. On both locations, I'm using Chrome Version 42.0.2311.152 (64-bit) on Ubuntu.
Why might the code have different results on jsfiddle and my website?
$(document).ready(function() {
var $item = $('div.item'), //Cache your DOM selector
visible = 2, //Set the number of items that will be visible
index = 0, //Starting index
endIndex = ($item.length / visible) - 1; //End index
$('div#arrowR').click(function() {
if(index < endIndex) {
index++;
$item.animate({
'left': '-=300px'
});
}
});
$('div#arrowL').click(function() {
if(index > 0) {
index--;
$item.animate({
'left': '+=300px'
});
}
});
});

It seems just as you said, 1.10.0 has some bug on that. I created an altered version of your jsfiddle, the only difference is that the jQuery is using version 1.10.0, you can see that it works like your site now.
See jQuery 1.10.1 Change log :
Effects
#13937: finish() only finishes last item of a set being .animate()d.
#13939: 1.10.0 breaks relative animation
and the issue ticket#13939 :
Description
Relative animation (using += or -=) is broken in 1.10.0. For example,
$('h1').animate({marginLeft: '+=100px'}); does not work.
So, you might have to switch to version 1.10.x where x is the latest version, as their change should mostly be issue fixes, not functionality changes.
The problem was that there is indeed a bug in 1.10.0, but for anyone in the future who has this problem but doesn't want to upgrade, I figured out a way to make this function work on 1.10.0.

I want to add two arrows to the sides of the "boxes" divs (below) to cycle through the 3 divs.
Working JSFiddle: https://jsfiddle.net/HBHcC/11/
Can someone help me with this?
HTML:
<div class="container">
<div class="boxes">
<div class="one box">
</div>
<div class="two box">
</div>
<div class="three box">

CSS:
.container{

position:relative;
}
.box {

.one{

}
.two{
background-color:red;
}
.three{
background-color:blue;
}
.boxes{
width:400px;
}
JS:
$(document).ready(function(){
$('.box').on("click", function() {
// Is this the last div, or is there a next one?
if ($(this).next().length) {
var animSpeed = 200; // Make this 0 for an instant change
$('.boxes').animate({marginLeft : "-=100"}, animSpeed);
}
});
});
After adding arrows to the div, here is a new fiddle that should get you started:
$('.rightarrow').on("click", function() {
// Is this the last div, or is there a next one?
var animSpeed = 200; // Make this 0 for an instant change
$('.boxes').animate({marginLeft : "-=100"}, animSpeed);
});
$('.leftarrow').on("click", function() {
// Is this the last div, or is there a next one?
var animSpeed = 200; // Make this 0 for an instant change
$('.boxes').animate({marginLeft : "+=100"}, animSpeed);
});
https://jsfiddle.net/tx2yg06w/1/
Updated w/arrows moved out of divs:
$(document).ready(function(){
var animSpeed = 200;
$('.rightarrow').on("click", function() {
if(parseInt($("#boxes").css("marginLeft")) == -200){ return;}
$('.boxes').animate({marginLeft : "-=100"}, animSpeed);
});
$('.leftarrow').on("click", function() {
if(parseInt($("#boxes").css("marginLeft")) == 0){ return;}
$('.boxes').animate({marginLeft : "+=100"}, animSpeed);
});
});

Errata has given you a good solution. Just wire up his code to the arrows in the snippet below.
