jQuery Toggle modification - javascript

I am using the below javascript (jQuery) to toggle open two DIVs. The DIVs open fine and open one at a time, which is what I am after. However, I also want the DIVs to close when they are clicked a second time, which doesn't happen despite my best efforts!
Javascript:
$(document).ready(function() {
$('.info_tab').click( function() {
var currentID = $(this).next().attr("id");
$('.toggle_info[id!=currentID]').hide(); /* the intention here is to hide anything that is not the current toggling DIV so as to close them as a new one is opened. I thought this would leave the currently selected DIV uninterrupted to toggle closed (below), but it doesn't */
$(this).next().toggle();
return false;
});
});
HTML:
<div class="info_tab">
<h1>Person One</h1><br />
<p>click for less info</p>
</div>
<div id="person_one_info" class="toggle_info">
<p>More information about Philip Grover</p>
</div>
<div class="info_tab">
<h1>Person Two</h1><br />
<p>click for less info</p>
</div>
<div id="person_two_info class="toggle_info">
<p>More information about Roy Lewis</p>
</div>
If any more info is needed, just ask and I'll be happy to edit the question.
Cheers,

you have the concept down, but not using the "currentID" correctly. You need to remember it's a variable, and can't be in another string if you want it evaluated.
With that said, try this:
$('.toggle_info[id!='+currentID+']').hide();
This makes the variable get evaluated in the selector, then passes it off to jQuery to find.
it looks like you're going to an accordian effect though. And jQuery UI has just such a control that you can use (if you're interested). if you're going for experience, then carry on. ;-)

DIV Splash Screen

How would I create a welcome screen on my web site? For Example: I have an image and a link that says "ENTER" when the user clicks enter the web site appears. How would I do that? Also if possible with JavaScript or JQuery, When the user clicks "ENTER", would it be possible to crossfade from the splash screen to the web site? I want that the link be functional within any element/tag on the DIV splash.
I have this code:
$('.Intro').click(function()
{
$(this).parent('#Intro').fadeOut(1000);
});
But it only works with:
<DIV id="Intro">
ENTER
</DIV>
And not with:
<DIV id="Intro">
<DIV class="EnterII">
ENTER
</DIV>
</DIV>
Therefore, just within the DIV Intro...
Why do you need to complicate?
As identifiers must be unique. Simply use ID selector
$('#Intro').fadeOut(1000)
<DIV id="Intro">
<DIV class="EnterII">
ENTER
</DIV>
</DIV>
With a little bit of indentation you can see that in this case the parent() function will return EnterII so that is the div that will be faded out. Use jquery closest() in order to get intro
$('.Intro').click(function(){
$(this).closest('#Intro').fadeOut(1000);
});
Have you tried just:
$('#Intro').fadeOut(1000);
instead of
$(this).parent('#Intro').fadeOut(1000);

Is there a way to add an element to the same height as another selected element dynamically?

I am new to front-end development. I was trying to code an annotation tool. A sample screen is shown on the image below. After the user select a sentence, an annotation box appears on the right side bar at the same horizontal position as the highlighted sentence. Any ideas about how I can achieve that effect?
Here is my html structure. I used the framework of Zurb Foundation:
<section id="main">
<div class="row">
<div class="small-8 large-8 columns"id="rawdata">
<p> <span class="sentence">2:22 So, last time I was here, I don't know if I told you this, but, um, we kind of did a "I like, I wish" activity on paper, about things that you like about studio, and things that you wish would change.</span><span class="sentence"> Um, do you want to share any of those thoughts now, so maybe we can talk about them? [name], I have yours if you want to look at it again.</span></p>
<p><span class="sentence">2:47 I forgot to add something.</span></p>
<p><span class="sentence">2:54 Well, I don't know, in terms of what I dislike about studio.</span></p>
<p><span class="sentence">2:57 So, some people wrote in theirs that, um, they dislike how cluttered it gets.</span></p>
<p><span class="sentence">5:09 I don't get bothered.</span>< <span class="sentence">I like the draftiness, I'm a little...</span><span class="sentence"> I'm one of the ones that opens the windows, and like—</span></p>
</div>
<div class="small-4 large-4 columns" id="annotations"><p></p>
</div>
</div>
</section>
JS for selecting sentence and adding annotations:
<script>
$('.sentence').click(function() {
$(this).toggleClass('sentenceStyle');
var y = $(this).offset().top;
var para = document.createElement("p");
$("#annotations").append(para);
para.innerHTML="this is an annotation";
para.css("position",'absolute');
para.style.top = y;
});
</script>
And here it is the fiddle: http://jsfiddle.net/yujuns/HDe6v/3/
There are some things that you want to change in your code.
First what you want is to get the offset of the selection. That can only happen if you put an html tag around the selection and then get its offset. You can then place an absolute positioned message box by setting its left and top offset to the offset you got from html element.
In the following fiddle, I have shown a basic implementation to give you the basic idea. Hope it helps.
Fiddle
EDIT:
Try this fiddle update.(In response to author's question). I have added comments to lines of code that I added to js. I also added position: relative to css for annotations
Updated Fiddle

Scroll to queued divs on click

I'm sure this is a pretty common question around here but after lots of research I can't seem to find an answer to my question.
So just a little warning; I'm really new into javascript and jQuery etc.
To the question! I'm trying to apply two images (It's img's that looks like buttons :P) which you click on and it scrolls to the "next" paragraph or div.
So to get an overview of how it looks, here' a part of the HTML:
<div id="scrollbuttons">
<img id="prev" src="pics/prev.png"></img>
<img id="next" src="pics/next.png"></img>
</div>
Also:
<div id="work">
<p class="maintext">blabla</p>
</div>
<div id="gallery">
<p class="maintext">blabla</p>
</div>
<div id="project">
<p class="maintext">blabla</p>
</div>
<div id="finish">
<p class="maintext">blabla</p>
</div>
So what I'm trying to create is when you click on "next", the page should smoothly and automatically scroll to firstly, "work", then to "gallery" etc.
And when you press "prev", the page should again smoothly and automatically scroll back to the previous point.
I have the latest jQuery version and I'd like to not install plugins if it's not absolutely needed.
So I hope this is enough info to get some help, I'd really appreciate it since I'm really new to JS.
Thanks in advance

Here you go, this could probably be done a little more efficiently but it's dynamic and it works. Click the buttons to go forward and backward. FYI I added a mutual class called section to all of your content divs
JSFIDDLE
var Section = "start";
$("#next").click(function(){
if(Section == "start"){
var nextSection ="work";
}else{
var nextSection = $("#"+Section).next(".section").attr("id");
}
$("html, body").animate({scrollTop: $("#"+nextSection).offset().top});
Section = nextSection;
});
$("#prev").click(function(){
var nextSection = $("#"+Section).prev(".section").attr("id");
$("html, body").animate({scrollTop: $("#"+nextSection).offset().top});
Section = nextSection;
});
maybe you need something like this
http://jsfiddle.net/urUFK/
the img would be inside of the anchor like this (semantics and W3C validation):
<img id="prev" src="pics/prev.png"></img>
on my version you just need to define the first element and the div id's

How do I target an <a> inside a <div>?

I have this code : http://jsfiddle.net/Qchmqs/BSKrG/
<div class="step"><-- this is darned wrong
<div id="step2"><a>Darn</a></div>
<div id="step2"><a>Darn</a></div>
<div id="step2"><a>Darn</a></div>
</div>
<div class="step"><-- this works fine
<div id="step2"><a>Darn</a>
<a>Darn</a>
<a>Darn</a></div>
</div>
The first block is three links inside three separate divs inside a surrounding div
The bottom block has the links inside one parent div
I am trying to change the background of an active link, but it won't turn off in the upper block.
The script works well with the bottom links but not working as expected with the upper ones
PS : The active class should be toggled only from the Links i have a lot of other scripts in the page that uses the .active links from this list.
For starters, do what JamesJohnson said and remove the multiple IDs. They can only cause you problems down the road.
In the upper links, the a tags aren't siblings because you put each one in its own div. So you need to do this to remove classes from the other as:
$(this).parent().siblings('div').children('a').removeClass('active');
http://jsfiddle.net/mblase75/BSKrG/1/
Unfortunately, that breaks the functionality on the lower links. You can achieve success in both places by adding andSelf to the parent siblings:
$(this).parent().siblings('div').andSelf().children('a').removeClass('active');
http://jsfiddle.net/mblase75/BSKrG/2/
It's not working on the upper ones because you're assigning the same id to the divs. You should probably use the class attribute instead:
<div class="step2"><a>Damn</a></div>
<div class="step2"><a>Damn</a></div>
<div class="step2"><a>Damn</a></div>
After making the above changes, you should be able to do this:
$(".step2 a").text("Hello World!");
maybe this:
<div class="step">
<div id="step2"><a>Damn</a>
<a>Damn</a>
<a>Damn</a></div>
</div>
<div class="step">
<div id="step2"><a>Damn</a>
<a>Damn</a>
<a>Damn</a></div>
</div>
Using radio inputs you can create this effect without any JS at all, which degrades gracefully from its intended appearance (a red backgrounded "damn") to damn with radios next to it (sending the same information).
ironically, this example at JSfiddle: http://jsfiddle.net/YvQdj/
My memory is a bit fuzzy, but I'm pretty sure this doesn't work in older versions of IE without some finagling.

jQuery: get a reference to a specific element without using id

I'm tinkering a bit with jquery to show a hidden div when a link is clicked. This should be fairly simple, but there's a flaw to it in this case. I have the following markup:
<div class="first-row">
<div class="week">
<p>Uge 2</p>
<p>(08-01-11)</p>
</div>
<div class="destination">
<p>Les Menuires</p>
<p>(Frankrig)</p>
</div>
<div class="days">4</div>
<div class="transport">Bil</div>
<div class="lift-card">3 dage</div>
<div class="accommodation">
<p><a class="show-info" href="#">Hotel Christelles (halvpension)</a></p>
<p>4-pers. værelse m. bad/toilet</p>
</div>
<div class="order">
<p>2149,-</p>
<p class="old-price">2249,-</p>
</div>
<div class="hotel-info">
<!-- The div I want to display on click -->
</div>
</div>
When I click the "show-info" link I want the "hotel-info" div to display.
My backend devs don't want me to use ids (don't ask me why..) and the above markup is used over and over again to display data. Therefore I need to be able to access the "hotel-info" div in the "first-row" div where the link is clicked.
I've tried to do something like:
$(document).ready(function() {
$('.show-info').click(function() {
var parentElement = $(this).parent().parent();
var lastElementOfParent = parentElement.find(".show-hotel");
lastElementOfParent.show();
});
});
But without a result :-/ Is this possible at all?
Any help is greatly appreciated!
Thanks a lot in advance!
Try this:
$('.show-info').click(function() {
$(this).closest('.accommodation').siblings('.hotel-info').show();
});
Even better imo, as it would be independent from where the link is in a row, if every "row div" has the same class (I assume only the first one has class first-row), you can do:
$(this).closest('.row-class').find('.hotel-info').show();
Reference: .closest, .siblings
Explanation why your code does not work:
$(this).parent().parent();
gives you the div with class .accommodation and this one has no descendant with class .hotel-info.
It is not a good idea to use this kind of traversal for more than one level anyway. If the structure is changed a bit, your code will break. Always try to use methods that won't break on structure changes.
You're right in not using an ID element to find the DIV you want :)
Use closest and nextAll
Live demo here : http://jsfiddle.net/jomanlk/xTWzn/
$('.show-info').click(function(){
$(this).closest('.accommodation').nextAll('.hotel-info').toggle();
});
