I am almost positive that this question has been answered before, but the reason that I am asking this question is because I am not sure how to implement the answers into my code without breaking it. I have an accordion menu and it utilizes headers, paragraph tags, divs for the structure of the accordion. Well what I am trying to do is use a div inside of the accordion to display images, but here is the thing: divs are used for the structure of the accordion.
So, what I am asking is how to have jQuery treat this div as purely
content and not part of the structure?
I am pretty sure that the answer is to use .not(), but not sure. I only understand the basics when it comes to JavaScript and jQuery. I am really sorry for this guys... I am the type of person that learns by doing, not by reading a book.
var headers = ["H1", "H2", "H3", "H4", "H5", "H6"];
$(".accordion").click(function(e) {
var target = e.target,
name = target.nodeName.toUpperCase();
if ($.inArray(name, headers) > -1) {
var subItem = $(target).next();
//slideUp all elements (except target) at current depth or greater
var depth = $(subItem).parents().length;
var allAtDepth = $(".accordion p, .accordion div:not(.exclude)").filter(function() {
if ($(this).parents().length >= depth && this !== subItem.get(0)) {
return true;
}
});
$(allAtDepth).slideUp("fast");
//slideToggle target content and adjust bottom border if necessary
subItem.slideToggle("fast", function() {
$(".accordion :visible:last").css("border-radius", "0 0 10px 10px");
});
$(target).css({
"border-bottom-right-radius": "0",
"border-bottom-left-radius": "0"
});
}
});

Edit: The above html is consolidated because there is a lot of content to include all of it, but I provide you with the basic structure that makes the accordion
Assign a class to your div (Ex. 'my-class')
Then use not :not() to filter the selection
var headers = ["H1","H2","H3","H4","H5","H6"];
$(".accordion").click(function(e) {
var target = e.target,
name = target.nodeName.toUpperCase();
if($.inArray(name,headers) > -1) {
var subItem = $(target).next();
//slideUp all elements (except target) at current depth or greater
var depth = $(subItem).parents().length;
var allAtDepth = $(".accordion p, .accordion div:not(.my-class)").filter(function() {
if($(this).parents().length >= depth && this !== subItem.get(0)) {
return true;
}
});
$(allAtDepth).slideUp("fast");
//slideToggle target content and adjust bottom border if necessary
subItem.slideToggle("fast",function() {
$(".accordion :visible:last").css("border-radius","0 0 10px 10px");
});
$(target).css({"border-bottom-right-radius":"0", "border-bottom-left-radius":"0"});
}
});

Considering that components such as dialogs, modals, tooltips, etc. should be of higher stacking index than any other elements in an HTML page, I placed these components in an immediate sibling of root element where all the other elements are placed. React developers will quickly recognize this and they'll know that I'm trying to use React Portals. You can visualize it here:
<body>
<div id="root">
// ----- other elements -----
<div id="supposed-parent" />
// ----- other elements -----
</div>
<div id="dialog-container">
<div id="supposed-child" />
</div>
</body>
So, how can I position #supposed-child next or beside #supposed-parent? Any help would be appreciated.
I don't think this is possible with a pure css. But with a little script we can achieve this. Take the offset-left and top of the supposed-parent and apply the same to the supposed-child. The child should be absolute positioned element. Check the below sample and It hope this will be useful for you.
Even though the supposed-child(yellow box) is independent of the supposed-parent, It will be always align with the top-left of the supposed-parent.
function offsetCalculate(){
var parentTop = $('#supposed-parent').offset();
var parentLeft = $('#supposed-parent').offset();
$('#supposed-child').css({
'top':parentTop.top,
'left': parentLeft.left
});
}
$(document).ready(function () {
offsetCalculate();
});
$(window).resize(function(){
offsetCalculate();
});
#supposed-child{
position: absolute;
background: yellow;
border-radius: 5px;
padding: 10px;
z-index: 999;
}

I’m new to jQuery/JavaScript but I have a solid idea of what I want, I’m just struggling to get it working.
I have a web page made up of different ‘div’s’ which have different ‘id’s’. I wrapped these divs in a pageContainer div. I want to be able to type a word in my ‘search bar’ and the word be looked for in the web page. It would signify a matching word by a collapsable div that would appear under the search bar which would have links to the different div id’s for where that word is. When clicked that word would be highlighted.
It’s simple but I figure it’s a good exercise to do.
Right now I know that I’m searching for the word in my pageContainer. As my understanding goes, I must search instead in each div, instead of the whole page. How can I do this?
Also as a side note, why is it that for every character I type, the search starts. Shouldn’t it only start on 3+ characters? I thought that’s what keyup does.
As of now, when I type in a word and search it, nothing happens on the web page.
/*Need to get the below search code working...*/
var thePage = $(".pageContainer");
// var content = $.makeArray(thePage.map(function(k, v){
// return $(v).text().toLowerCase();
// }));
$("#search").keyup(function(){
var input = $(this).val();
console.log(input);
//if match found, make corresponding div link appear in open collapsible div,
// else say nothing found in open collapsible div
// console.log(
thePage.filter.(function(index, value){
var foundText = $(this).val().toLowerCase();
// console.log(foundText, " BAAAAA");
console.log(index, value, " Second Here");//find 'user' input in value
// console.log(foundText.indexOf(input) >= 0);
console.log($(value).find(foundText.indexOf(input) >= 0));
// $(value).filter(foundText.indexOf(input) >= 0);
$(value).find(foundText.indexOf(input) >= 0);
var highlight = '<span class="word">' + value + '</span>';
});
// );
});
Interesting task, to sum it up the requirements are:
A web page made up of different ‘div’s’ which have different ‘id’s’.
These divs wrapped in a pageContainer div.
Type a word in my ‘search bar’ and the word be looked for in the web
page.
Signify a matching word by a collapsable div that would appear
under the search bar which would have links to the different div id’s
for where that word is.
When clicked that word would be highlighted.
Search should start on 3+ characters
I took all the above into consideration and created this codepen demo
(search for 'elementum' for example).
P.S. The highlight function is quite basic, it would be much better and safier to rely on a plugin like these.
var thePage = $(".pageContainer");
$('#results').hide(); //Hide the results div at first
$("#search").keyup(function() {
//Empty and hide the results div everytime the user types something
$('#results').empty();
$('#results').hide();
//Get the typed value
var input = $(this).val();
//Do nothing if it's smaller than three characters
if (input.length < 3) return;
//iterate through the results
var results = $(".pageContainer>div:contains('" + input + "')");
var counter = 0;
results.each(function(index, value) {
counter++;
//Get the current div that contains the given text
currentId = $(this).attr('id');
console.log('div' + index + ':' + currentId);
//Create a new element in the search div below the search input
var newP = $('<p/>', {
text: currentId
}).click(function() {
//Highlight when click
highliter(input, $(this).text());
});
$('#results').append(newP);
});
//Collapse if no results found
if (counter) $('#results').show();
else $('#results').hide();
});
function highliter(word, id) {
//Remove whatever was already highlighted
$('*').removeClass('highlight');
//Create a regular expression for the given word
var rgxp = new RegExp(word, 'g');
//Replace the plain text with a highlighted one
var repl = '<span class="highlight">' + word + '</span>';
var element = document.getElementById(id);
element.innerHTML = element.innerHTML.replace(rgxp, repl);
//Scroll to the position of the results
$('html, body').scrollTop($(".highlight").offset().top);

I am using jQuery to detect which div is bigger out of two columns. The smaller div gets a class of .js-small-content. That class has a position:fixed on it.
However the issue that I am having is that I need to be able to scroll the fixed content. Which I understand sounds weird as why would I want to scroll something thats fixed?
If you take a look at my jsFiddle you will see that I need to be able to scroll the cat content so I can see all the images.
This is an example of the effect that I am after. You can see that the small content allows you to scroll it first and then once it has all been viewed it then fixes to the bottom of the content and continues scrolling the images on the left.
I think I may need to do something with the viewport on scroll but I'm not sure how to achieve this?
Here is my code:
var a = document.querySelector('#single__images');
var b = document.querySelector('#single__content');
var aH = a.scrollHeight;
var bH = b.scrollHeight;
(aH > bH ? b.classList.add("js-small-content") : a.classList.add("js-small-content"));
HTML:
<article>
<div id="single__image"><img src="#"/></div>
<div id="single__content">Text goes here</div>
</article>
I have worked really long for this, as was challenging for me. Finally made it.
According to you, you want to add class and remove class to smaller one among two div's. Which i have accomplished(but its' not right way to do at all) with my own other way.
I have made the smaller div to stop scroll when reaches at three fourth of window position from top.
JSFiddle : Demo
$(window).scroll(function()
{
var divImg = document.getElementById("single__images").id;
var divCont = document.getElementById("single__content").id;
// Height of single__content
var hC = $("#" + divCont).outerHeight();
// Height of single__images
var hI = $("#" + divImg).outerHeight();
// Check out the smaller one
if(hC<hI)
{
var samllOne = document.getElementById("single__content").id;
}
else
{
var samllOne = document.getElementById("single__images").id;
}
// Height of Smaller Div
var h = $("#" + samllOne).outerHeight();
// Position of Smaller Div from top
var topPos = $("#" + samllOne).position();
var topPos = topPos.top;
// Height of Smaller Div
var h = $("#" + samllOne).outerHeight();
// Div Height + TOP Space from from Body
var bottomCont = topPos + h;
// Checks current Scroll
var curScroll = $(this).scrollTop();
var windowH = $(window).innerHeight();
var windowMid = windowH / 2;
var midOfMid = windowMid / 2;
var threeFourth = windowMid + midOfMid;
var bottomTouch = h - threeFourth;
if(curScroll >= bottomTouch)
{
$("#" + samllOne).css({position: "fixed", top: "-" + bottomTouch + "px" });
}

I updated your JSFiddle project.
I just added the following to your CSS file. Hope this helps and is kind of self explaining.
.js-small-content {
position:absolute;
overflow-y:scroll;
overflow-x:hidden;

i am trying through jquery to remove a div completely when there is no child element within it. The variable I am using is an image. I can't seem to select the variable as an image, i only know how to do this through text. Could someone please help me and resolve this issue, so it detects that there is a img contained within the div and displays it and when there isn't an image it doesn't display it.
I have uploaded it through jsfiddle:http://jsfiddle.net/cLkFD/

You can check to see whether any image inside your div or not using length:
$(function () {
$('.picture').each(function () {
if ($(this).find('img').length) {
$(this).hide();
}
});
});
http://jsfiddle.net/9VBJP/
The above fiddle should work
$('.picture').each(function(){
var imageElem = $(this).find('img');
if(imageElem.length == 0) {
$(this).hide();
}
});
Let say I have a very long page of content consisting of multiple paragraphs which cannot be
displayed in a single browser window with vertical scrollbar
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
So I want to cut the paragraphs and format them into multiple pages, e.g.
<!-- page 1 -->
<p>...very long sentence ...</p>
<p>...very long </p><!-- the ending p tag is automatic inserted since the following text cannot be displayed -->
<!-- page 2 -->
<p>sentence ...</p>
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
Are there any existing scripts for this purpose?
In the extreme case the paragraph might contain image, so each line might be variying in height.
Someone has created show/hide functionality with jQuery.
This may help you.

In case of paragraph with image and other html tags use below logic:
<div style="height:500px;overflow:hidden" id="blah">
Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.
</div>
Show more
<script>
$("#showmore").live('click', function() {
$("#blah").css('height','1000px');
});
</script>

See this DEMO
By using the below code you can paginate limitless paragraphs as according to your need.
jQuery:
$(document).ready(function(){
//how much items per page to show
var show_per_page = 5;
//getting the amount of elements inside content div
var number_of_items = $('#content').children().size();
//calculate the number of pages we are going to have
var number_of_pages = Math.ceil(number_of_items/show_per_page);
//set the value of our hidden input fields
$('#current_page').val(0);
$('#show_per_page').val(show_per_page);
//now when we got all we need for the navigation let's make it '
/*
what are we going to have in the navigation?
- link to previous page
- links to specific pages
- link to next page
*/
var navigation_html = '<a class="previous_link" href="javascript:previous();">Prev</a>';
var current_link = 0;
while(number_of_pages > current_link){
navigation_html += '<a class="page_link" href="javascript:go_to_page(' + current_link +')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>';
current_link++;
}
navigation_html += '<a class="next_link" href="javascript:next();">Next</a>';
$('#page_navigation').html(navigation_html);
//add active_page class to the first page link
$('#page_navigation .page_link:first').addClass('active_page');
//hide all the elements inside content div
$('#content').children().css('display', 'none');
//and show the first n (show_per_page) elements
$('#content').children().slice(0, show_per_page).css('display', 'block');
});
function previous(){
new_page = parseInt($('#current_page').val()) - 1;
//if there is an item before the current active link run the function
if($('.active_page').prev('.page_link').length==true){
go_to_page(new_page);
}
}
function next(){
new_page = parseInt($('#current_page').val()) + 1;
//if there is an item after the current active link run the function
if($('.active_page').next('.page_link').length==true){
go_to_page(new_page);
}
}
function go_to_page(page_num){
//get the number of items shown per page
var show_per_page = parseInt($('#show_per_page').val());
//get the element number where to start the slice from
start_from = page_num * show_per_page;
//get the element number where to end the slice
end_on = start_from + show_per_page;
//hide all children elements of content div, get specific items and show them
$('#content').children().css('display', 'none').slice(start_from, end_on).css('display', 'block');
/*get the page link that has longdesc attribute of the current page and add active_page class to it
and remove that class from previously active page link*/
$('.page_link[longdesc=' + page_num +']').addClass('active_page').siblings('.active_page').removeClass('active_page');
//update the current page input field
$('#current_page').val(page_num);
}
HTML:
<!-- the input fields that will hold the variables we will use -->
<input type='hidden' id='current_page' />
<input type='hidden' id='show_per_page' />
<!-- Content div. The child elements will be used for paginating(they don't have to be all the same,
you can use divs, paragraphs, spans, or whatever you like mixed together). '-->
<div id='content'>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
<p>Vestibulum consectetur ipsum sit amet urna euismod imperdiet aliquam urna laoreet.</p>
<p>and so on....</p>
</div>
<!-- An empty div which will be populated using jQuery -->
<div id='page_navigation'></div>
A while ago, I created pagify, a jQuery plugin to do just that. It detects page height by splitting elements into words and incrementally adding the words until the height reaches a specified height. I've given it some CSS to make it look like pages in the demo below, but you can style it to use 100% width and height. You can call it simply with $('body').pagify(options); The default options are as follows
{
'pageTag' : 'div', // the tag which surrounds each page
'pageClass': 'page', // the class of the page tag
'innerClass': 'page-inner', // the class of the inner page element
'pageSize': 'A4', // a class added to the page so that the size can be defined by css
'pageSizeClassPrefix': 'page-', // the prefix to the above class
'pageOrientation': 'portrait', // not yet used, but could be used to flip width and height
'splitElementClass': 'split-element' // elements which have been split across two pages are given this class
};
So to use 100% width and height:
html, body, page-screen-size {
width: 100%;
height: 100%;
}
and
$('body').pagify({
pageSize : 'screen-size'
});
Here it is in action: http://jsfiddle.net/nathan/nfHHE/
From what I understand this is very similar to the way an online reader works, where content is formatted into different pages or slides and it doesn't matter what the content inside it is, as this will adapt to its container.
In order to achieve your goal, I'd recommend CSS3 Multi-column layout (see http://www.w3.org/TR/2001/WD-css3-multicol-20010118/)
CSS
#your-container
{
width: 90%;
margin: 0 auto;
overflow: hidden; //Hide overflowing content
padding: 20px 0;
}
#div-inside-container //For padding and columns display purposes
{
position: relative;
-moz-column-count: 1;
-webkit-column-count: 1;
column-count: 1;
-moz-column-width: 50em;
-webkit-column-width: 50em;
column-width: 50em;
-webkit-column-gap: 0;
-moz-column-gap: 0;
column-gap: 0;
}
JQUERY
$(window).resize(function() {
//Resize container
$(div_content).height(Dimensions.TellMeHeight() - padding);
});
See example and code: http://jsfiddle.net/GLbXX/1/
you can use jquery accordion control, if you have multiple paragaraphs than you should divide then in accordion, it will improve the readabilty and look of your page

The Financial Times has developed a JavaScript solution for multi-column layout with special focus on complicated (i.e. newspaper-like) cases, FTColumnFlow.
If you set a container to the width of one column and do then some pagination, i.e. via jQuery UI tabs, this might be a solution, that caters most difficult cases.
I hope this code help you. Maybe there is some cases which are omitted or you can find a better alhorithm or you can optimize it. It is just a way to lead you.
$(document).ready(function(){
var current_page_height = $(window).innerHeight() - $("div.pagination").innerHeight();
function createPages(page_height){
var current_page_height = 0;
var pages = [];
var current_page = [];
var cpt_page = 0;
$("div.content").children().each(function(index, element){
var el = $(element);
el.hide();
if(current_page_height + el.innerHeight() > page_height){
var height_over = (current_page_height+el.innerHeight()) - page_height;
var line_height_el = el.css("line-height").replace("px","")
if( line_height_el < height_over && el.find("img").length == 0){
var number_line_to_remove = Math.round(height_over/line_height_el);
var number_line = el.innerHeight() / line_height_el;
var char_by_line = Math.floor(el.html().length / number_line);
var content_el = el.html();
var pointer_substr = (number_line - number_line_to_remove) * char_by_line;
while(content_el.charAt(pointer_substr) != " " && pointer_substr > 0){
pointer_substr--;
}
var new_element = $("<p>" + content_el.substr( pointer_substr, content_el.length-1) + "</p>");
el.html( content_el.substr(0, pointer_substr+1));
current_page.push(el);
el.after(new_element);
el = new_element;
el.hide();
}
pages[cpt_page] = current_page;
current_page_height = 0;
current_page = [];
cpt_page++;
}
current_page.push( el );
current_page_height += el.innerHeight();
});
if(current_page.length > 0){
pages[cpt_page] = current_page;
}
return pages;
}
function displayPage(page_to_display){
if( page_to_display >= 0 && page_to_display < pages.length){
$(pages[page_to_display]).each(function(index, element){
element.show();
});
$(pages[$("span.page").html()]).each(function(index,element){
element.hide();
});
$("span.page").html(page_to_display);
}
}
var pages = createPages(current_page_height);
displayPage(0);
$("span.next").click(function(){
var page = new Number($("span.page").html());
displayPage( page+1 );
});
$("span.prev").click(function(){
var page = new Number($("span.page").html());
displayPage( page-1 );
});
});
