after logging on to facebook, there is a downward arrow symbol after home tab. On clicking it shows a div (?) which just appears on the existing content and on another click it disappears.
How can I make exactly such a thing?
Edit:
I followed this link from TheBlackBenzKid. One thing is clear, on clicking on the button, just 2 divs are toggled.
But AFAIK toggle takes place on mouse click. so the 'click' event should be there in the jquery code.
1) But I didn't find it. where is that?
2)there is some css that makes it possible for the menu to appear on a place without dislocating the existing content there( from the demo this is not visible, but it does happen actually). What is that css code?
There are so many ways to do these things: thefinishedbox.com/files/freebies/dropdown-gui/index.html this is a nice one that already comes with simple clean CSS look and feel
This is how i wouldve done it, but its a pretty basic solution.
div id="arrowid">▼</div>
<div id="dropdownbox" style="display:none;">Dropdownbox</div>
<script type="text/javascript">
$(document).ready(function() {
$('#arrowid').click(){
$('#dropdownbox').toggle();
});
});
</script>
this one does'nt support outside clicks, it just shows and hides when clicking the arrow. Hope it helps!
You can use .slideToggle() to achieve this effect, if you are using jQuery.
Use it to display or hide the matched elements with a sliding motion.
.slideToggle( [duration] [, easing] [, callback] )
duration: A string or number determining how long the animation will run.
easing: A string indicating which easing function to use for the transition.
callback: A function to call once the animation is complete.

I want to have a page turn effect like the one seen on this page: jFlip demo except I want to automate the page turning, like make it happen every second, 20 times (or however many images I have). I want to be able to trigger this animation to run either on page load, when a button is clicked, etc.
Unfortunately I don't understand jQuery all that well and the plugin's events seem rather complicated to me, probably mostly due to my inexperience with jQuery. Any help on which direction I should go, methods I should try? I am not limiting myself to jQuery or even Javascript, this is just the example I have found that achieves my desired effect.
You can find the updated code here. replace this with old one.
Usage :
var jFlip = new Flip("#g1",300,300,{background:"green",cornersTop:true,scale:"fit"});
// here #g1 is a jquery selector (make sure it returns only one).
// The structure is Flip(JQselector,width,height,options)
then use the jFlip object to flip slides/pages
jFlip.flipMe() // for next slide
jFlip.flipMe(true) // for prev slide
for binding a function to slide change event you can use
$("#g1").bind("flip.jflip",function(event,index,total){
$("#l1").html("Image "+(index+1)+" of "+total);
});
// here the selector is same as the one passed inside jFlip function.
Try this and let me know the feedback.
I am fairly new to jQuery, but I feel like I have a pretty decent grasp on it. Or at least this part of it. I've been through quite a few tutorials on jQuery, but I've never run into this problem before.
I want to hover on an image and have it reveal a small paragraph beside it. I have written this jQuery that does exactly what I want it to do, except it only works once. Hovering over the image reveals the description paragraph, and moving outside the image hides it again, but then hovering won't do anything. Any ideas why this might be?
$(document).ready(function(){
$('#novelDescrip').hide();
$('#barDescrip').hide();
$('.novel').hover(function(){
$('#novelDescrip').fadeIn('slow', 1);
},
function(){$('#novelDescrip').hide();}
);
$('#barminder').hover(function(){
$('#barDescrip').fadeIn('slow', 1);
},
function(){$('#barDescrip').hide();
});
});
This should explain the use of toggle as well as the link Jorge posted.
How do I check if an element is hidden in jQuery?
Here are a few methods to get you started with the jQuery toggle function:
$('.click').click(function() {
$('.target').toggle();
});
$('.click').click(function() {
$('.target').slideToggle();
});
$('.click').click(function() {
$('.target').fadeToggle();
});
The slide and fade are used to give the toggle a slide or fade out effect.
You can also use the following attributes for different things:
$('element:hidden')
$('element:visible')
Or you can do the same with is:
$(element).is(":hidden")
$(element).is(":visible")
Answer to your question: since you didn't post your html I can't test anything for you, but I'd recommend following the tutorials stated above or changing hide() to show() at some parts of your code.
Hope that helps.
i want to implement a right side sliding menu similar to the one in amazon.com..
i am trying to use javascript to edit the script on every mouseover/onclick event..
i want to hide/show the table on every event.
function show(a){
var id="myMenu"+a
if (i<-12){
i=i+speed;
document.getElementById(id).style.left=i;
}
}
function hide(a){
var id="myMenu"+a
if (i>-135){
i=i-speed;
document.getElementById(id).style.left=i;
}
}
this should be good to show/hide the tables.. but how to id dynamically add two tables one over another..because the main menu table will always be visible, but the sub menu when hidden will be beneath the main menu..
any method to do the same?
am i in the right path?
Definitely on the right path, this is a good test of concept.
I would suggest you look at jQuery (or other JavaScript libraries like Scriptaculous) specifically at the slideToggle() and toggle() methods.
Don't want to give it all away, but take a look at the Amazon source code, you may get some helpful little tips. :P
I'm currently working on a website for a Danish company. The content is all in one page and I've included some jQuery-scrolling and stuff. Works nice!
For the menu I'm asked to programme the elements so the active element is bold. That I've done too.
The problem comes here:
The client wants a home button and a next and previous button. But when I click them and the page scrolls the CSS-classes do not change for the active element - so the bold element in the menu is still the last clicked page.
I hope that anyone can help.
The page can be seen at:

In addition to calling the serialscroll plugin, the event handler for the images needs to update the appropriate class name on your navigation link. When you click on a navigation link directly, you call the changeActiveStates function, but that isn't happening with the home, next, and previous buttons.
You should use the onBefore attribute of the serialScroll plugin to define a method that will figure out which navigation link is supposed to receive the class name. It can then call the changeActiveStates function.
It doesn't look like it would take more than a few more lines of code to fix your problem. If you need more help getting it to work, let me know.
edit:
If you add this (starting at line 84 of init.js), you should be in business:
easing: 'swing',
onBefore:function(e, elem, $pane, $items, pos){
if ((pos >= 0)&&(pos < $('ul.navigation > li > a').size())) changeActiveStates($('ul.navigation > li > a').get(pos));
return true;
}
You will then need to call changeActiveStates (probably after you initialize the function) on page load to initialize the correct menu item.
I hope that helps; let me know if it gives you any more trouble.
You used minified version of scripts so it is very hard to debug the code. Also you didnt give us name of plugin you use. I think there is a bug in plugin. Because css class "selected" sould jump from one menu item to another.
#Jason Francis:
You're probably right. I'm not that much into jQuery and Javascript and what I've done so far is more luck than it's knowledge. I did A LOT of trial and error.
I understand what you're saying about getting the serialScroll plugin to figure out what element to call changeActiveStates on - but I seriously don't know how to do that.
I found an anchor plugin for jQuery, and its demo site is at http://www.position-relative.net/creation/anchor/.
I am developing a FAQ page on a website where a list of questions are followed by a list of answers. I could use the scroll effect to move down to the corresponding answer when a user click a question. But I also want the answer is highlighted in some ways or others so that a user can get focused on the answer.
I would like to achieve the effect. Also, if you know any other plugin to do this, please let me know.
As you invoke the anchor plugin using:
$(document).ready(function() {
$("a.anchorLink").anchorAnimate()
});
you could also bind your own function that does the highlighting as so:
$(document).ready(function() {
$("a.anchorLink").anchorAnimate().click(function() {
$('.highlight').removeClass('highlight');
$('a[name='+$(this).attr('href').substring(1)+']').next().addClass('highlight');
});
});
This requires that you have this kind of structure:
Anchor link
...
<a name="foobar"></a>
<div>The content you want to highlight</div>
And in CSS, you just define how you want the highlighted part to look like:
.highlight {
background: #ffc;
}
The jQuery code works so that when you click an anchor link, it first removes current highlights and then applies the highlight class to the element immediately after the link target.
You could expand this functionality by doing some kind of color fade animation like here in SO, but this should get you started.
I'd use jquery.scrollTo personally, to highlight it is pretty simple, just use .toggleclass() on the span/div that wraps the answer.
