Prevent toggleClass to be used on every element on the page

I have a function which, when clicking on a link with the class .show-more, opens up the div with the class .productinfo. Now, it also adds a class to the link itself (.active) - the problem what I have is that I have a few links on this page with the same class. I've managed to only open up the correct .productinfo when clicking on it, but the class will be added to every link nonetheless. Also tried adding the following to the code but that did not work:
$(this).find('show-more').toggleClass("active");
My structure is the following:
<div class="main-content">
<div class="col-1">Content 1</div>
<div class="col-2">Content 2</div>
<div class="col-3"><a class="show-more">Show more</a></div>
<div class="productinfo">This content is hidden and will be shown when clicked</div>
</div>
<div class="main-content">
<div class="col-1">Content 1</div>
<div class="col-2">Content 2</div>
<div class="col-3"><a class="show-more">Show more</a></div>
<div class="productinfo">This content is hidden and will be shown when clicked</div>
</div>
jQuery(document).ready(function($) {
$('body').on('click', 'a.show-more', function(e) {
e.preventDefault();
$('.show-more').toggleClass("active");
var $this = $(this).parents('.product');
$this.find('.productinfo').toggle(0, 'slide')
});
});

Why not:
$('a.show-more').on('click', function(e)
and then
$(this).toggleClass("active");

Jquery scroll navigation can't detect current section

I made a page that contains several divs with class content
<div class="content" id="content-0">content 1</div>
<div class="content" id="content-1">content 2</div>
<div class="content" id="content-2">content 3</div>
<div class="content" id="content-3">content 4</div>
<div class="content" id="content-4">content 5</div>
I also made 2 links that switch between next and previous div
<div class="nav">
<a id="prev" href="#">previous</a>
<a id="next" href="#">next</a>
</div>
I used TwinMax and ScrollTo plugins to make navigate between the divs
var section = 0;
var number = $('.content').length;
$("#next").click(function(e){
e.preventDefault();
if(section < number){
section++;
}
TweenMax.to(window, 0.5, {scrollTo:{y:$("#content-" + section).offset().top}});
});
$("#prev").click(function(e){
e.preventDefault();
if(section > 0){
section--;
TweenMax.to(window, 0.5, {scrollTo:{y:$("#content-" + section).offset().top}});
}
});
Here is aJSFiddle.
The problem is this:
When I scroll with the mouse to the last section and then click the next buttom , the page scrolls back to the second section .
How do I detect the current div so the next button goes to the next div correctly?

The accepted answer on this question might help you: Check if element is visible after scrolling
After checking if the element is on the page you could set section = element number.

How to access the dom by knowing the value of a node && Getting the index of accordion by just knowing value

I have 2 questions:
1) Since I have similar structure for the html contents and the only difference is that class title contents are different. I tried using $(div .title:contains("cat")) also
$(div .title).text()="cat")
2)How can I get the index of the accordion by just checking the $(div a) contents are required ones. I tried using $(div a).text()=="cat"
Check the codes here:
HTML1 contents
<div class="mod moduleselected" id="mod969">
<div class="content module moduleselect">
<div class="hd" ><div class="inner">
<div class="title">cat</div>
<ul class="terminallist"></ul>
<ul class="buttons">
<li class="help"></li>
<li class="show" ></li>
</ul>
</div>
</div>
</div>
<div class="mod moduleselected" id="mod969">
<div class="content module moduleselect">
<div class="hd" ><div class="inner">
<div class="title">rat</div>
<ul class="terminallist"></ul>
<ul class="buttons">
<li class="help"></li>
<li class="show" ></li>
</ul>
</div>
</div>
</div>
<div class="mod moduleselected" id="mod969">
<div class="content module moduleselect">
<div class="hd" ><div class="inner">
<div class="title">dog</div>
<ul class="terminallist"></ul>
<ul class="buttons">
<li class="help"></li>
<li class="show" ></li>
</ul>
</div>
</div>
</div>
Accordian
<div id="dia">
<div id="dialog" title="Detailed FeedBack ">
<div id="accordion">
<h3>dog</h3>
<h3>cat</h3>
<h3>rat</h3>
</div>
</div>
</div>
Javascript
$('div .title').mouseover(function() {
if($("div a").text().indexOf("cat")!=-1)
{
$("#accordion").accordion("activate", 1);
}
$('div .title').mouseleave(function(){$("#accordion").accordion("activate", -1); });
});
Here is what I am trying to do with this javascript code. When I mouse over the cat contents I want the accordion with cat contents to open. And when I leave it to close the accordion selection.
When I hover my mouse over the html contents cat ,rat. It should side by side open the accordion button of those contents. Example: I hovered over rat (of html contents) I should see accordion rat open (or active i.e. contents visible).

Updated (see demo)
It sounds like you want something like this: when a content section is hovered over, find the title of that section, match its text against the text of the <a> elements in the accordion, and activate that section:
$(function() {
$("#accordion").accordion();
var links = $('#accordion a').map(function() {
return $(this).text().trim().toLowerCase();
}).toArray();
$('div.content').mouseover(function() {
var title = $(this).find('div.title').text().toLowerCase();
var index = links.indexOf(title);
if (index != -1) {
$("#accordion").accordion("activate", index);
}
});
});​
P.S. jQuery does have a .hover() method for this as well.

It should be as succinct as the following (with potential minor tweaks):
$('.content .title').hover(function(e){
var index = this.textContent.split(/\W/)[1] - 1;
$("#accordion").accordion('activate', index);
});
​
Be careful with the HTML as this regular expression is overly simple in that it just grabs the last "word" which in the case of your example is a number. We subtract one to get a zero-based index. That will break if you add further text to the element.

jQuery - how to run one event while delaying another?

I'm a bit of a jQuery newbie, so forgive me if this seems a bit simple! I am setting up a sliding header system, which works very much like an accordion menu, however the links to open and close the elements are in a different part of the HTML, so all the accordion tutorials I found didn't work.
I have got this so far: HTML:
<div class="drawer" id="drawer_about"></div>
<div class="drawer" id="drawer_contact"></div>
<div class="drawer" id="drawer_hire"></div>
<div class="drawer" id="drawer_social"></div>
...
<ul class="navigation">
<li><span>About Me</span></li>
<li><span>Get In Touch</span></li>
<li><span>Hire Me</span></li>
<li><span>Social Networks</span></li>
</ul>
And jQuery:
$(document).ready(function(){
$("#drawer_about").hide();
$("#drawer_contact").hide();
$("#drawer_hire").hide();
$("#drawer_social").hide();
lastBlock = ("#drawer_hire");
$('.show_hide_about').click(function(){
$("#drawer_about").slideToggle(700);
$(lastBlock).hide(700);
lastBlock = ("#drawer_about");
});
$('.show_hide_contact').click(function(){
$("#drawer_contact").slideToggle(700);
$(lastBlock).hide(700);
lastBlock = ("#drawer_contact");
});
$('.show_hide_hire').click(function(){
$("#drawer_hire").slideToggle(700);
$(lastBlock).hide(700);
lastBlock = ("#drawer_hire");
});
$('.show_hide_social').click(function(){
$("#drawer_social").slideToggle(700);
$(lastBlock).hide(700);
lastBlock = ("#drawer_social");
});
});
Am I going OTT here? is there a simpler way to do this?
The main problem I'm having is it all works, however if the ABOUT ME panel is open and the user clicks the HIRE ME link, I get a weird effect. What I'd want in this situation is for the ABOUT ME panel to fold up, then the HIRE ME panel to fold down.
Hope that makes sense, thanks folks,
Alex

I'd set up the links like this: asdf
Then you all you need is:
$('.show').click(function(ev) {
var $visibleDrawer = $('.drawer:visible').eq(0); // make sure to get only one (or 0) drawer
// set currentSection to the drawer's id or empty if no drawer was found
var currentSection = $visibleDrawer.length?$visibleDrawer.attr('id').replace('drawer_',''):'';
$('.drawer').slideUp(700);
$('a.show').removeClass('active'); // reset all link classes
(function(clickedSection, $link){ //<-- pass the active link to have access to it inside the closure
if(currentSection != clickedSection){
$link.addClass('active'); // set active class on clicked link
setTimeout(function() {
$('#drawer_'+clickedSection).slideDown(700);
}, ($visibleDrawer.length?700:0)); // set the timeout to 0 if no drawer visible
}
})($(this).data('section'),$(this)); //<--
ev.preventDefault();
});

using .animate() you can parse a callback function which will be executed at the end of the animation, or you can use .queue() to keep track of the point of execution against and element. Some pseudo code of the first way
$('#foo').animate(function() {
// do stuff with foo
}, duration, easing, function() {
$('#bar').animate(function() {
// do stuff with bar
})
});

Here is a link to how it works on jsFiddle (Note that you should choose framework to be jQuery)
I think this would work with you :
$(document).ready(
function(){
$('.header').click(function(){
//To hide all other contents
$('.content').slideUp('slow');
var num=$(this).attr('id').split('_')[1];
//And show this one ..
$('#content_'+num).slideDown('slow');
});
}
);
HTML should look like this :
<div class="header" id="title_111">Category 1</div>
<div class="content" id="content_111">
</div>
<div class="header" id="title_112">Category 2</div>
<div class="content" id="content_112">
</div>
<div class="header" id="title_113">Category 3</div>
<div class="content" id="content_113">
</div>
<div class="header" id="title_114">Category 4</div>
<div class="content" id="content_114">
</div>
<div class="header" id="title_115">Category 5</div>
<div class="content" id="content_115">
</div>
<div class="header" id="title_116">Category 6</div>
<div class="content" id="content_116">
</div>

How can I hide elements in my list and add a 'show more' feature?

I'm using javascript to build a list of results. I have a for-loop that iterates over some data and creates a mydata div, and adds that to the results div. Let's pretend it looks something like this:
<div id="results">
<div class="mydata">data 1</div>
<div class="mydata">data 2</div>
...
<div class="mydata">data 20</div>
</div>
What I want to do is only display 5 results at a time, and should the user wish to see more, they can click a show next 5 or show more button (or something similar). Any ideas?
Just to clarify, every time the user clicks "show more" I want to 'unhide' the next 5 elements, not ALL the remaining elements. So each click reveals more elements until all are displayed.

You can use the gt() and lt() selectors along with :visible pretty well here.
The following will show the next 5 results on clicking and removes the link once all items are visible.
$('.mydata:gt(4)').hide().last().after(
$('<a />').attr('href','#').text('Show more').click(function(){
var a = this;
$('.mydata:not(:visible):lt(5)').fadeIn(function(){
if ($('.mydata:not(:visible)').length == 0) $(a).remove();
}); return false;
})
);
working example: http://jsfiddle.net/niklasvh/nTv7D/
Regardless of what other people are suggesting here, I would not hide the elements using CSS, but do it in JS instead, because if a user has JS disabled and you hide the elements using CSS, he won't get them visible. However, if he has JS disabled, they will never get hidden, nor will that button appear etc, so it has a full noscript fallback in place + search engines don't like hidden content (but they won't know its hidden if you do it on DOM load).

My solution is here: jsFiddle.
You can put this link somewhere:
show more
and use the following code:
var limit = 5;
var per_page = 5;
jQuery('#results > div.mydata:gt('+(limit-1)+')').hide();
if (jQuery('#results > div.mydata').length <= limit) {
jQuery('#results-show-more').hide();
};
jQuery('#results-show-more').bind('click', function(event){
event.preventDefault();
limit += per_page;
jQuery('#results > div.mydata:lt('+(limit)+')').show();
if (jQuery('#results > div.mydata').length <= limit) {
jQuery(this).hide();
}
});
where limit is your current number of results displayed and per_page is number of results shown with each click on "show more". The link disappears if all the results are displayed. See how it works on jsFiddle.

You can create a CSS class like:
.hiddenData { display: none }
and attach it to any quantity of divs that exceeds 5.
After that make handlers for adding/deleting this class from the needed quantity of divs.
jQuery for class removing:
$(".hiddenData").removeClass("hiddenData")

Create a class with something like:
.hidden_class{
display: none;
}
Add this class to all the mydata div's that you dont want seen.
when the user click the button, remove it from the next 5 div's.
repeat everytime the user clicks the "read more" button

This should work...Let me know how it goes
<script type="text/javascript">
function ShowHide(id) { $("#" + id).toggle(); }
</script>
<div id="results">
<div class="mydata">data 1</div>
<div class="mydata">data 2</div>
<div class="mydata">data 3</div>
<div class="mydata">data 4</div>
<div class="mydata">data 5</div>
<div style="clear:both" onclick="ShowHide('grp6')">More</div>
<div id="grp6" style="display:none">
<div class="mydata">data 6</div>
<div class="mydata">data 7</div>
<div class="mydata">data 8</div>
<div class="mydata">data 9</div>
<div class="mydata">data 10</div>
</div>
<div style="clear:both" onclick="ShowHide('grp11')">More</div>
<div id="grp11" style="display:none">
<div class="mydata">data 11</div>
<div class="mydata">data 12</div>
<div class="mydata">data 13</div>
<div class="mydata">data 14</div>
<div class="mydata">data 15</div>
</div>
</div>
In your forloop, you also have to add these divs hidden container
<div style="clear:both" onclick="ShowHide('grp6')">More</div>
<div id="grp6" style="display:none">
You get the idea.

Here you have:
<style>
/*This hides all items initially*/
.mydata{
display: none;
}
</style>
Now the script
<script>
var currentPage = 1; //Global var that stores the current page
var itemsPerPage = 5;
//This function shows a specific 'page'
function showPage(page){
$("#results .mydata").each(function(i, elem){
if(i >= (page-1)*itemsPerPage && i < page*itemsPerPage) //If item is in page, show it
$(this).show();
else
$(this).hide();
});
$("#currentPage").text(currentPage);
}
$(document).ready(function(){
showPage(currentPage);
$("#next").click(function(){
showPage(++currentPage);
});
$("#prev").click(function(){
showPage(--currentPage);
});
});
</script>
And a sample html:
<div id="results">
<div class="mydata">data 1</div>
<div class="mydata">data 2</div>
<div class="mydata">data 3</div>
<div class="mydata">data 4</div>
<div class="mydata">data 5</div>
<div class="mydata">data 6</div>
<div class="mydata">data 7</div>
<div class="mydata">data 8</div>
<div class="mydata">data 9</div>
<div class="mydata">data 10</div>
<div class="mydata">data 11</div>
<div class="mydata">data 12</div>
</div>
Previous
<span id="currentPage"></span>
Next
The only thing remaining is to validate fot not going to a page lower than 1 and higher than the total. But that will be easy.
EDIT: Here you have it running: http://jsfiddle.net/U8Q4Z/
Hope this helps. Cheers.
