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.

This seems to be a common question, however when I check the answers, they're all different.
I have a row of five links. Each has a corresponding div below. When I click a links, I want its div to display and all others to hide.
Here's some code I came across that seems to be on the right track:
$('a').on('click', function(){
var target = $(this).attr('rel');
$("#"+target).show().siblings("div").hide();
});
But if I use "a" without a destination, clicking the link takes me to the top of the page. I just want the divs below to show or hide...
Can I use "button" or "div" instead of "a"? If so, what would I use instead of "rel"?
Sorry for the noob question. I just can't seem to make any of the solutions I've found here work for my site. What's the simplest way to do this?
Here's some HTML that definitely works with the jquery script above:
$('a').on('click', function() {
var target = $(this).attr('rel');
$("#" + target).show().siblings("div").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Week 3
Week 4
<div>
<div id="week_3" style="display: none">[..xz.]</div>
<div id="week_4" style="display: none">[...]</div>
</div>
However if my href="", clicking that link bounces me up to the top of my page for some reason. So I'd rather use a clickable div or a button rather than a hotlink. In which case, what can I use in the script instead of "rel"?
It seems you only need to prevent the default behaviour by adding e.preventDefault();
$('a').on('click', function(e) {
e.preventDefault();
var target = $(this).attr('rel');
$("#" + target).show().siblings("div").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Week 3
Week 4
<div>
<div id="week_3" style="display: none">[..xz.]</div>
<div id="week_4" style="display: none">[...]</div>
</div>
You can use below values on your href.
Anchor
Here is the complete explanation for javascript:void(0)
The JavaScript void operator evaluates the given expression and then
returns a value of undefined. https://www.quackit.com/javascript/tutorial/javascript_void_0.cfm
Try using href="javascript:" or href="#" instead of leaving the attribute empty. href="" tells the browser to reload the current page that you are in, which is why it bounces you to the top of the page.
You can also use <button> or <div>, the effect will not be very different from using <a>. You can also use rel if you are using <button> or <div>. In fact, it is arguably better to use rel on <button> and <div> because the attribute does not have any functional purpose in those tags. On the contrary, <a> uses the rel attribute to specify a few things to browsers.
Target attribute does not suitable for divs it is only for windows or iframes. Also, hyperlink should has href attribute otherwise it will be an anchor or placeholder link in HTML5 specifications.
You may use any conjugation attributes between the link and its div such as link title will be div id.
Example:
Show DIV 1
Show DIV 2
Show DIV 3
<div id="div1" class="linked-div" style="display: none"> One</div>
<div id="div2" class="linked-div" style="display: none"> Two</div>
<div id="div3" class="linked-div" style="display: none"> Three</div>
<script>
$("a").click(function(){
divId = $(this).attr("title");
$(".linked-div").each(function(){
if ($(this) == $("#"+divId)){
$(this).show()
}
else{
$(this).hide()
}
})
$("#"+divId).show();
})
</script>
DEMO
I have a comment system and I would like to implement the "Show Replies (2)" slide down effect.
This is an example of my setup.
<div class="comment">
<div class="main-comment">
Message.
Show Replies (1)
</div>
<div class="sub-comment">
Funny comment up there, mate.
</div>
</div>
But because both the main comment and its sub comments are dynamically generated using ajax, setting event handlers was a little tricky. This is how I did it:
$(".comment").delegate('.show-replies', 'click', function(event) {
$(this).parent().next(".sub-comment").slideDown();
});
I've tried to make the setup as simple and close to the real thing as possible.
What am I doing wrong and how do I solve it?
<div class="comment">
<div class="main-comment">
Message.
Show Replies (1)
</div>
<div class="sub-comment" style="display: none">
Funny comment up there, mate.
</div>
</div>
<script>
$(document).ready(function() {
$('.show-replies').on('click', function() {
$('.sub-comment').slideToggle();
});
});
</script>
In order to bind to NEW dynamic content you need to tell jquery where it is going to be.. Also make sure to use the latest jQuery, delegate is old.
<div class="comments">
<div class="main-comment">
Message.Show Replies (1)
</div>
<div class="sub-comment" style="display: none">
Funny comment up there, mate.
</div>
</div>
<script>
$(document).ready(function() {
$('.show-replies').on('click','.comments', function() {
$('.sub-comment').slideToggle();
});
});
</script>
Notice the .on(eventType, selector, function) signature.
This will work for dynamic content, anything loaded INTO the div class 'comments' - jQuery will always travesre that container from fresh, instead of caching it.
Also- dont just do it on the entire page,because it will cause slow response, since, every click, it will try and bind to the selector.
Replacing
$(this).parent().next(".sub-comment").slideDown();
with
$(this).parent().parent().next(".sub-comment").slideDown();
Fixed the problem.
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'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();
});
I am wanting to use jquery to do a show/hide of a DIV from a text link.
What makes it a little different from the examples I have found of this site so far is I need a generic way of doing it multiple times on 1 page and also able to use it sitewide on anypage.
It would be really nice if I can put the JS in seperate file that is included into the pages, so maybe it can be wrapped into a function?
Can someone help me here? For making it generic it could be where I assign a div that is shown/hidden with an id like id="toggle-hide-1" and just change the numbers in my page to make it a different show/hide area
I could just name the ID using a name that will make the function show/hide a div and to seperate it from other divs that show/hide on a page I could add a number to it.
below is partial code that will do a show/hide of a div on a link click but is not exactly what I need.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" >
$(function() {
$(".view-code").click(function(evt) {
$(".tool_block, .view-code").toggle();
});
});
</script>
<a href="#" class="view-code" >view code</a>
hide code <br />
<div class="tool_block" style="display:none" >
this stuff is hidden until we choose to show it!
</div>
The best approach is probably going to be something using custom attributes. If you markup your anchor with an attribute that tells the jquery which div to toggle, it will be easier to write generic code to do the work.
Something like this:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" >
$(function() {
$(".view-code").click(function(evt) {
var d = $(this).attr("toolDiv");
$(".tool_block[toolDiv=" + d + "], .view-code[toolDiv=" + d + "]").toggle();
});
});
</script>
<a href="#" class="view-code" toolDiv="1" >view code</a>
hide code <br />
<div class="tool_block" toolDiv="1" style="display:none" >
this stuff is hidden until we choose to show it!
</div>
Then give each of your anchor-div pairs a unique toolDiv value (doesn't have to be a number).
If you could wrap the whole collection in a div, it would make it pretty easy.
$(function() {
$(".view-code").click( function(e) {
$(this).siblings().andSelf().toggle();
});
});
<div>
<a href="#" class="view-code" >view code</a>
hide code <br />
<div class="tool_block" style="display:none" >
this stuff is hidden until we choose to show it!
</div>
</div>
If it doesn't handle the <br />, you could filter the siblings to only div and anchor elements.
Why not use specific classes instead? Each element you want shown/hidden can have a class called "toggler," as in:
<div class="toggler">
...
</div>
You can then toggle the visibility of ALL elements with this class at once, with:
$(".toggler").toggle();
In this scenario, it doesn't make a difference where in the document these elements reside or even what kind of elements they are.
If this functionality needs to be available globally, you can always extend jQuery itself with a custom function, as in:
$.toggleTogglers = function(toggleClass) {
$("." + toggleClass).toggle();
};
This is nice in that you have flexibility to choose a toggle custom class of your own design.
