Imagine a Bootstrap collapse with 3 parts
<div class="panel-group" id="accordion">
...
<div id="accordionOne" class="panel-heading"></div>
...
<div id="accordionTwo" class="panel-heading"></div>
...
<div id="accordionThree" class="panel-heading"></div>
</div>
Is there a simple way to make the plugin open the given HTTP fragment identifier ?
Example http://myproject/url#accordionTwo would open the second accordion
$("#accordionTwo").collapse('show');
To open the given HTTP fragment identifier, try this:
$(document).ready(function() {
var anchor = window.location.hash;
$(".collapse").collapse('hide');
$(anchor).collapse('show');
});
EDIT:
As pointed by bart in the comments:
be careful with targeting .collapse because this class is also used for the navigation bar when the viewport is xs.
This line will open the correct hash
location.hash && $(location.hash + '.collapse').collapse('show');
Yet another solution, a bit smaller and compact:
$(document).ready(function() {
var anchor = window.location.hash;
$(anchor).collapse('toggle');
});
For really simple and quick to implement hash routing, you could try something like Routie
routie({
accordionOne: function() {
$('#accordionOne').collapse('show');
},
accordionTwo: function() {
$('#accordionTwo').collapse('show');
},
accordionThree: function() {
$('#accordionThree').collapse('show');
}
});

I am using Lazy as a lazy image loading plugin. I have a div where I load divs like this:
<div class="nano-content" id="lScroll">
/*... MORE LIKE THIS ... */
<div class="card">
<div class="city-selected city-medium clickChampion pointer"
data-champ-id="1">
<article>
<div class="info">
<div class="city">
CHAMPNAME
</div>
</div>
</article>
<figure class="cFigure lazy" data-src="images/champions/CHAMPNAME_0.png"></figure>
</div>
</div>
/*... MORE LIKE THIS ... */
</div>
So I initiate the plugin and it works for the first ones visible and when I scroll:
var $lazy = $('#lScroll .lazy');
if ($lazy.length) {
$lazy.Lazy({
appendScroll: $('#lScroll')
});
}
But now I have a function that "filters" the divs by their attributes when I enter sth in my search input and it fails to load the image when the according div is shown:
$(document).on("keyup", "#searchVod", function () {
var $search = $(this);
var $sVal = $search.val().toLowerCase();
if ($sVal !== "") {
$(".vodCard").hide();
$('[data-champ*="' + $sVal + '"]').show();
$('[data-role*="' + $sVal + '"]').show();
} else {
$(".vodCard").show();
}
});
I tried bind: "event" /w and w/out delay: 0 (loading the plugin in the search function) but when I searched it would load ALL images immediately in the background.
Any hint highly appreciated
UPDATE: I just noticed in Chrome DevTab after entering one letter in my searchbox it loads ALL the images and eventually the one I am searching for (if its the last it takes some time (30MB sth)
There is an excellent library called Lozad.js which can help you to make it easier to load your images like lazy load do but in easier way.
You can download it here from Github.
Demo page here.
Explanation:
This library will load your images one by one on scrolling to each image anchor by class name.
Example
HTML:
At the header ->
<script src="https://cdn.jsdelivr.net/npm/lozad"></script>
Image element should looks like this:
<img class="lozad" data-src="image.png">
Javascript
// Initialize library
lozad('.lozad', {
load: function(el) {
el.src = el.dataset.src;
el.onload = function() {
el.classList.add('fade')
}
}
}).observe()
Hope it will help you.
Best,
Ido.
I need to write an efficient code in order to keep it simple & code file small, also I want to use the knowledge I hopefully get from here in future codes.
UPDATE: Just to be clear - my example is fixed "buttons" on browser window side & if you click on one of them, it takes you to div with same ID (look at code below).
IMAGE:
MY CODE EXAMPLE:
//Smooth Scroll Menu Links
jQuery('.div1').on('click', function(e) {
e.preventDefault();
jQuery('html,body').animate({scrollTop:jQuery(this.hash).offset().top-100}, 800);
});
//I have to copy-paste it 1000 times & only change the ".div1" to something else
//Note that I need a solution with different class names, not "div1", "div2" etc but e.g "location", "potato", "car" etc.
How to make this code working without writing same lines for every single div?
There got to be a way to get class from item you click & then scroll to item with same name ID, right? Or any other way to keep codes shorter in that kind of situations - otherwise it's just copy-paste-huge-file fest.
You can give each button a class so you can catch them all, than go to the element you want to scroll to by looking at the attribute of the clicked button :)
HTML
<div class="buttons" data-scroll="div1">div1</div>
<div class="buttons" data-scroll="div2">div2</div>
<div class="buttons" data-scroll="div3">div3</div>
<div class="content" id="div1">some content</div>
<div class="content" id="div2">some content</div>
<div class="content" id="div3">some content</div>
JS
$('.buttons').on('click', function(e) {
e.preventDefault();
var scrollTarget = $(this).data("scroll");
scrollme(scrollTarget);
function scrollme(target) {
$('html,body').animate({scrollTop:$("#"+target).offset().top}, 800);
}
});
example: http://jsfiddle.net/7gd66kr1/1/
try this i hope will work with you :
jQuery('div').on('click', function(e) {
e.preventDefault();
jQuery('html,body').animate({scrollTop:jQuery(this.hash).offset().top-100}, 800);
});
note that : this function will aplay on all divs in page
I think there are more than an unique solution. If you don't want to modify your HTML, then you need a condition to determine if the clicked element is an "active" one:
jQuery('div').on('click', function(e) {
var id = $(this).attr('class');
var scrollto = $('#' + id);
if(scrollto.length > 0) {
e.preventDefault();
jQuery('html,body').animate({scrollTop:scrollto.offset().top-100}, 800);
}
});
If you "can" modify your HTML, it's wise to add some attribute to the "active" elements (the ones that are buttons), so you know they scroll the page, or put them inside a container. The attribute you add may be a class or any other valid attribute (I recommend "rel", but might be "data" as spotted by #Iliya Reyzis , who selects by class and scrolls to "data") and select them by it:
<div class="div1" rel="mybutton">div1</div>
jQuery("[rel='mybutton']").on('click', function(e) {
var id = $(this).attr('class');
var scrollto = $('#' + id);
e.preventDefault();
jQuery('html,body').animate({scrollTop:scrollto.offset().top-100}, 800);
});
Hope it helps!!
I've searched through StackOverflow for what I regard as a basic issue, but I could not find any relevant threads. Mainly because I feel like I am searching for the wrong keywords.
I would like to know how the summarize the next bit into as few lines of code as possible. When you click on 'link-#', it loads the content from the hidden div 'more-#' (where the # in more could be any number, but is the same as the number in link-#.) Right now I have this:
jQuery("#link-1").click(function(){
jQuery('#more').hide().html($('#more-1').html()).fadeIn(400)
});
jQuery("#link-2").click(function(){
jQuery('#more').hide().html($('#more-2').html()).fadeIn(400)
});
jQuery("#link-3").click(function(){
jQuery('#more').hide().html($('#more-3').html()).fadeIn(400)
});
etc.
I assume it should be something like below, but obviously it's not the correct way.
jQuery("#link" + NUMBER ).click(function(){
jQuery('#more').hide().html($('#more-' + this.NUMBER).html()).fadeIn(400)
});
I bet you guys know exactly how to deal with this! Thank you for your help.
Best regards,
Thomas
A preferable approach is to group these items by giving them the same class, and use a data-* attribute to identify the associated element:
jQuery(function() {
jQuery(".show-more").click(function() {
var target = $(this).data('target');
jQuery('#more').hide().html($(target).html()).fadeIn(400);
});
});
#moreItems {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
Show More 1
Show More 2
Show More 3
<div id="more"></div>
<div id="moreItems">
<div id="more-1">Here are the details 1</div>
<div id="more-2">Here are the details 2</div>
<div id="more-3">Here are the details 3</div>
</div>
Give them all the same class name and then add the attribute "data-num" and then:
jQuery(".className").click(function () {
var $this = $(this);
var html = jQuery('#more' + $this.attr('data-num')).html();
jQuery('#more').hide().html(html);
});
Example HTML:
<a class='className' data-num='1'>Link</a>
<div id='more1'></div>
<div id='more'></div>
What I'd like to do is have all elements of class collapsible_list not displayed by default (with one exception... see below*), and then toggle their display when their parent <div class="tab_box"> is clicked. During the same click, I'd also like for every other element of class collapsible_list to be hidden so that only one of them is expanded at any given time.
*Furthermore, when the page initially loads I'd also like to check to see if an element of collapsible_list has a child a element whose class is activelink, and if there is one then I'd like that link's parent collapsible_list element to be the one that's expanded by default.
Here's some sample html code:
<style>
.collapsible_list {
display: none;
}
.collapsible_list.active {
display: block;
}
</style>
<div id="sidebar">
<div class="tab_box">
<div class="collapsible_tab">2014</div>
<div class="collapsible_list panel-2014">
1
2
3
</div>
</div>
<div class="tab_box">
<div class="collapsible_tab">2013</div>
<div class="collapsible_list panel-2013">
<a class="activelink" href="/2013/1">1</a>
2
3
</div>
</div>
</div>
And here's where I'm currently at with the javascript (although I've tried a bunch of different ways and none have worked like I'd like them to):
$(document).ready(function() {
// This looks redundant to me but I'm not sure how else to go about it.
$(".collapsible_list").children("a.activelink").parent(".collapsible_list:not(.active)").addClass("active");
$(".tab_box").click(function() {
$(this).children(".collapsible_list").toggleClass("active").slideToggle("slow", function() {
$(".collapsible_list.active:not(this)").each(function() {
$(this).slideToggle("slow");
});
});
});
});
I hope that's not too confusing, but if it is then feel free to let me know. Any help is much appreciated.
Since you have a dom element reference that needs to be excluded use .not() instead of the :not() selector
jQuery(function ($) {
// This looks redundant to me but I'm not sure how else to go about it.
$(".collapsible_list").children("a.activelink").parent(".collapsible_list:not(.active)").addClass("active").show();
$(".tab_box").click(function () {
var $target = $(this).children(".collapsible_list").toggleClass("active").stop(true).slideToggle("slow");
//slidup others
$(".collapsible_list.active").not($target).stop(true).slideUp("slow").removeClass('active');
});
});
Also, instead of using the slide callback do it directly in the callback so that both the animations can run simultaniously
Also remove the css rule .collapsible_list.active as the display is controlled by animations(slide)
Try This.
$('.collapsible_tab a').on('click', function(e){
e.preventDefault();
$('.collapsible_list').removeClass('active')
$(this).parent().next('.collapsible_list').toggleClass('active');
});
Fiddle Demo
I think your code would be less complicated if you simply remembered the previously opened list:
jQuery(function($) {
// remember current list and make it visible
var $current = $('.collapsible_list:has(.activelink)').show();
$(".tab_box").on('click', function() {
var $previous = $current;
// open new list
$current = $('.collapsible_list', this)
.slideToggle("slow", function() {
// and slide out the previous
$previous.slideToggle('slow');
});
});
});

I'm trying to implement multiple scrollbars with the plugin Tinyscrollabr.js
http://baijs.nl/tinyscrollbar/
To implement the scrollbars, i use a function scrollify like in this article :
http://www.eccesignum.org/blog/making-tinyscrollbarjs-easier-to-implement
HTML :
<ul id="myList">
<li id="scrollbar1" class="col">
<h2>Title 01</h2>
<div class="scrollBox"><!--Scrollable Content here--></div>
</li>
<li id="scrollbar2 class="col">
<h2>Title 02</h2>
<div class="scrollBox"><!--Scrollable Content here--></div>
</li>
<li id="scrollbar3 class="col">
<h2>Title 03</h2>
<div class="scrollBox"><!--Scrollable Content here--></div>
</li>
</ul>
Javascript :
function scrollify(element,options) { // '#element', {list:of,key:values}
var opt = options || {}
$(element).children().wrapAll('<div class="viewport"><div class="overview"></div></div>');
$(element).prepend('<div class="scrollbar"><div class="track"><div class="thumb"><div class="end"></div></div></div></div>');
$(element).tinyscrollbar(options);}
$scrollbar1 = $('#scrollbar1 .scrollBox') ;
$scrollbar2 = $('#scrollbar2 .scrollBox');
$scrollbar3 = $('#scrollbar3 .scrollBox');
$scrollbar4 = $('#scrollbar4 .scrollBox');
$(function() {
scrollify($scrollbar1);
scrollify($scrollbar2);
scrollify($scrollbar3);
scrollify($scrollbar4);
})
I would to make this more simple.
For example, i would to be able to make this :
$(function() {
scrollify('.scrollBox');
})
But tinyscrollbar need an id. With a class, it's load the first scrollbar and not the others. Firebug return this error message "f.obj[0] is undefined"
Sorry if my question is stupid, but how can I do for applying tinyscrollbar to a list of elements with a class ?
And then, after some actions how to update all this scrollbars with the function $allScrollbars.tinyscrollbar_update();
Thanks for help, I'm just beginning with javascript and i'm trying to learn.
I would count the number of elements with the class:
var scrollCount = $(".scrollbox").size();
Then use an iterating loop to call each of your IDs:
for (i=0; i<5; i++) {
scrollify($('#scrollbar' + i));
}
Also I would recommend using DIVs instead of the list setup you have, use the example from the link you shared as a starting point :)
Thanks KneeSkrap3r for your answer. It's a good solution to make this but i'm trying to do something in the case i' don't know the numbers of element to scroll.
I think I've found with something like this (it's a part from the first jquery plugin i'm trying to do ) where $el is all elemnts with the class"scrollbox".
$el.each(function(index)
{
var $scrolls = $(this);
function scrollify(element,options)
{ // '#element', {list:of,key:values}
var opt = options || {}
$(element).children().wrapAll('<div class="viewport"><div class="overview"></div></div>');
$(element).prepend('<div class="scrollbar"><div class="track"><div class="thumb"><div class="end"></div></div></div></div>');
$(element).tinyscrollbar(options);
}
scrollify($scrolls);
// Update heights
$(window).resize(function()
{ $scrolls.tinyscrollbar_update('relative');
});
})
Like this, it's seems to work but i don't know if i'm using good practice of javascript.
For the Html markup, I told the li elements for div, it's better for the semantic.
Thanks for tips ;-)
