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

I have a parallax scrolling website which works via section ID's. I have animations on each of the sections but only want them to activate when the section is in the viewport. I currently have the following, which doesn't seem to be working. I'm fairly new to jquery/javascript so any help would be appreciated!
function paintLine(){
$('#3-Backup-3').lazylinepainter({
"svgData": svgData,
'ease': 'easeInOutQuad',
'strokeCap': 'square'
}).lazylinepainter('paint');
}
var element_position = $('#backup-section-3').offset().top;
$(window).scroll(function() {
var y_scroll_pos = window.pageYOffset;
var scroll_pos_test = element_position;
if(_scroll_pos > scroll_pos_test) {
paintLine();
}
});
<!-- Backup 3 -->
<div data-anchor="backup-section-3" class="section backup-section-3">
<div class="float-left">
<div id="backup-nav">
<p onclick="openSideNavGreen()" class="nav-section-title">Backup</p>
</div>
<div>
<p class="backup-text-title">Methods</p>
<p class="backup-text">No surprises here then: tape as a primary backup method remains at an all-time low of 3%. This is the first year it hasn’t fallen – possibly indicative of how stubborn some legacy systems (often populated with static compliance data) can be. I wouldn’t be surprised to see similar figures next year.<br><br>We did see a drop in the prevalence of combined disk/tape solutions, with a new option, External Hard Drive/USB, seeming the preferred choice instead.</p>
</div>
</div>
<div class="float-right">
<div id="3-Backup-3"></div>
</div>
</div>
$('#backup-section-3').offset().top; refers to an element with an ID of backup-section-3 which you don't seem to have in your HTML markup. Try giving the element that you're referring to an ID of backup-section-3 and see if that resolves your issue.
id needs the start with alpha character. put any alpha char in front of the 3 in your javascript and html and it will work.
I have many questions here so please be patient with me, very new jquery/javascript user.
Here is my current page http://integratedcx.com/index.php/experience
Basically I would like each of the projects and project categories to have the hidden div, slidedown like a drawer not just appear as they do now.
I have tried to achieve this through jquery without much success, here is my working http://integratedcx.com/temp/slide.html
How do I get the div below the one opening to "ease" down instead of jump
How do I get my close feature (orange box) in recent projects to work properly
How do I get my the project list on the right side of image to hide (as it does on my current page) as well as have the drawer opening effect.
Is there an easy way to i.e. variable to assign this to multiple divs using jquery.
Thank you in advanced for any/all help.
For your question 4, With the following script (based on ComputerArts's answer above), you can easily add the slide effect to a large number of divs:
$(document).ready(function () {
$(".toggle-to-show").click(function (evt) {
var targetdiv = $(evt.currentTarget).attr("data-drawer");
$(targetdiv).slideToggle(1000, function() {
if ($(this).is(':visible')) {
$('.bracket', evt.currentTarget).html('less');
$('.project', evt.currentTarget).hide();
$('.closebox', this).bind('click', function(e) {$(evt.currentTarget).triggerHandler('click');});
}
else {
$('.bracket', evt.currentTarget).html('more');
$('.project', evt.currentTarget).show();
$('.closebox', this).unbind('click');
}
});
})
})
Then, you can mark up the toggle buttons and sliders as follows:
<div class="toggle-to-show" data-drawer="#firstsection">
<div class="project">Project One Heading</div>
<div class="bracket">more</div>
</div>
<div id="firstsection">
<h3>Project One Heading</h3>
stuff
<img class="closebox" src="close.jpg">
</div>
<div class="toggle-to-show" data-drawer="#secondsection">
<div class="project">Project Two Heading</div>
<div class="bracket">more</div>
</div>
<div id="secondsection">
<h3>Project Two Heading</h3>
stuff
<img class="closebox" src="close.jpg">
</div>
<div class="toggle-to-show" data-drawer="#thirdsection">
<div class="project">Project Third Heading</div>
<div class="bracket">more</div>
</div>
<div id="thirdsection">
<h3>Project Three Heading</h3>
stuff
<img class="closebox" src="close.jpg">
</div>
As for points #1 and #2, try this fiddle
I only changed the first script tag to
<script type='text/javascript'>
$(document).ready(function () {
$(".projectx-show").click(function () {
$("#projectx").slideToggle(1000, function() {
if ($(this).is(':visible')) {
$('#projectx-bracket').html('less');
}
else {
$('#projectx-bracket').html('more');
}
});
})
})
</script>
FYI, you don't need to use $(window).load and then $(document).ready... one is enough
As for #3, I don't understand what you're trying to say.
#4, yes there is a way, using classes and keeping the structure the same for every bloc in your page.
http://api.jquery.com/slideDown/
$("#link_id").click(function(){
$("#div_to_show").slideDown();
});
http://api.jquery.com/slideUp/
$('#div_to_close').slideUp();
Using both of the methods from 1, and 2
By using class names instead of IDs for your selectors. For example:
$(".link_class").click(function(){
$(this).parentsUntil('.ex-wrapper').find('.div_to_show').slideDown();
});
I have the following JavaScript at the end of the body of my HTML:
<script>
$(document).ready(function() {
$("a").click(function(event) {
var div_to_show=event.target.id;
var real_div=div_to_show.split('-');
var display_div=real_div[0];
var elementPos=$("#"+div_to_show).offset();
var top_pos=elementPos.top-118.5;
$('#board-right div').hide();
$("#" + display_div).css('margin-top',top_pos);
$("#" + display_div).show();
});
});
</script>
And here is the HTML that it is supposed to manipulate:
<div id="board-left">
<div id="board-names">
<a id="marci-link">Marci Weisler</a><br />
<a id="nicholas-link">Nicholas Rey</a><br />
</div>
</div><!-- #board-left -->
<div id="board-right">
<div id="marci" style="display:none;">
<p>
Marci Weisler is an accomplished...
</p>
</div>
<div id="nicholas" style="display:none;">
<p>
Nicholas Rey is a French-born...
</p>
</div>
</div><!-- board-right -->
So, the code should get the div name from the clicked link, remove the "-link" portion, and then show the appropriate div. Currently nothing is happening when I click the link. As I'm writing this, I am wondering if it is a CSS issue? Any ideas?
By the way, there is a link in the document to jQuery 1.3.
if you check http://jsfiddle.net/pramodpv/YvYBD/,
you will find that the top pos is negative.. if u correct that as u require it will work
PS: try using jsfiddle while posting your questions so that people can work on your code and give faster answers... Most prb, you will find the answer yourself :D
Trying your example, I found that I had to add an href='#' attribute to the hyperlinks and then added an event.preventDefault() as the first line in your click handler.
And same as Pramod SyneITY, the top position needs to evaluate as a positive value for the text to be visible.
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. ;-)
So I'm designing a website (using WordPress), and I want to use JQuery to hide/show a certain element when another element is moused over. The HTML looks roughly like this
<div class="post" style="clear:both;">
<a href="...">
<img src="..." />
</a>
<div class="autohide">
<h3>
...
</h3>
<p>....</p>
</div>
</div>
...
<div class="spacer" />
and the JQuery looks like this:
jQuery(document).ready(function(){
jQuery(".post .autohide").hide();`
jQuery(".post").hover(function() {
jQuery(this).nextAll(".spacer").first().stop().html(jQuery(this).children(".autohide")
.html()).fadeIn();
},function() {
jQuery(this).nextAll(".spacer").stop().show().fadeOut().html("").hide();
});
});
What's supposed to happen is, when the user mouses over the image, the contents of the associated autohide <div> get transplanted into the next spacer <div> and then faded in; when they mouse out, the autohide <div> fades out and clears.
However, if the pointer is not over the image for the full fade-in time, then the max opacity of the spacer div seems to decrease until a mouse-over creates no effect at all.
I would be much obliged if anyone who knows more JQuery than I could shed some light on this subject; I assume it's a basic problem (I've never used JQuery before this project).
Thanks in advance.
I took the .stop() calls out, and it seems to work fine, but I am still trying to parse everything that is going on.
