Mysterious padding increase

I'm learning and learning, currently creating a validation class. I have one little bug that I would ask you guys, what you think of it.
tooltip part of Javascript
this.toolTip = function(){
var selector = $("#regForm #"+this.idName);
$(selector).focus(function(){
tooltip = "<div class='tooltip'>"+tooltip+"</div>";
$(selector).after(tooltip);
}); // focus
$(selector).blur(function(){
$('.tooltip:parent').remove();
}); // blur
};
This is the tooltip function I wrote, basically what I expect it to do is showing the tooltip in that div, then delete not just the text, but the div, too. I think it's working perfectly, but the css don't say that.
tooltip part of CSS
.tooltip {
display: inline-block;
float: none;
background: #333;
color: #f9f9f9;
font-size: 10px;
padding: 5px;
}
My experience is pretty poor in CSS yet, but I'm developing and I'm trying.
When I focus on an input again, it's padding increasing, when I click again, it increases again. Can you guys help me inspect the code? http://purpost.me/o/form
(as design, I tried to copy tipsy tooltip)
Here is a picture of the bug:
Thanks in advance! :)
UPDATE:
Updated jsFiddle: http://jsfiddle.net/ThePianist/hExkP/3/
When I change the CSS .tooltip's padding to zero, the padding doesn't increase, but the div looking bad obviously. When I tried <div class="tooltip"><span>'+tooltip+'</span></div> and give the span the padding attribute, it started growing on focus again .. :/

What's happening is when clicking inside the form inputs there is some script appending more empty divs underneath <div class="tooltip"><div>. So when you click out and click back in, it is registering another instance of the click and appending again thus making the tooltip larger. Therefore, it would appear is a javascript error with the append/after section. If you pop your codes in a jsFiddle i can take a proper look at a solution for you :)
EDIT:
From looking at the code, it is the section:
$(selector).focus(function(){
tooltip = "<div class='tooltip'>"+tooltip+"</div>";
$(selector).after(tooltip);
}); // focus
That appears to be causing issues. Ideally it should check to see if the code added after already exists, and if it does, don't run the after function again

Found the solution! A friend of mine called my attention to this line:
JS before
tooltip = '<div class="tooltip '+selector.attr('id')+'T">'+tooltip+'</div>';
I call the class property tooltip as well, now I overwrote that with this line.
JS after
$(selector).focus(function(){
var tooltipHTML = '<div class="tooltip '+selector.attr('id')+'T">'+tooltip+'</div>';
selector.after(tooltipHTML);
}); // focus
"The problem is that you are using the variable tooltip for multiple things. The before code defining a variable called tooltip with html in it and it's used for text
+tooltip+ part in JavaScript, you don't want to declare variables globally like this."

jQuery Tools - Tooltip issue

Have a tooltip issue here. Hope somebody could help tweak the code a little bit.
I'm using the jQuery Tools for implementing a tooltip. I need tooltips to open from separate div where I can use any html code. So far I have just one tooltip to open:
<script src="http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js"></script>
<script>
$(document).ready(function() {
$("#download_now").tooltip({
offset: [5, 0],
effect: 'slide'
}).dynamic({ bottom: { direction: 'down', bounce: true } });
});
</script>
And it works fine except I need more tooltips added.
Could anybody help modifying the script so more tooltips could be added by their id?
Here is the JSFiddle with one tooltip (working)
Here is the JSFiddle with more tooltips (not working)
I'm sure there should be an easy fix. I'm just not a javascript specialist.
Thanks!

Ok i got it. I apologize, I thought you were using jquery-ui tooltip (which provide - according to me - better widgets than the lib you are using).
By reading the documentation i found that :
After this the element next to the trigger is being used as the tooltip
meaning that your tooltip contents (with html as you specified) need to be placed after the element on which you want a tootip, like this :
Lorem ipsum
<a id="download_now1" class="need_tooltip">
<strong>dolor sit amet</strong>
</a>
<div class="tooltip">
<p><strong>Some sample text</strong> with html within...</p>
</div>
Have a look in this jsFiddle.
If you can't put your tooltips contents directly after your elements i would suggest you to use jquery-ui which is more flexible to define tooltips contents.
EDIT to provide a jquery-ui version
jquery-ui tooltips basically closes when element looses focus, so you can't hover the tooltip (to click on a link inside for example). But there is a workaround to prevent tooltip from closing for such case :). Thus i think this new jsFiddle is filling your requirements.

isotope image onclick to reveal new content in top div Wordpress

I'm trying really hard to replicate what happens here angular theme on Wordpress.
I've been able to get isotope to filter the post_thumbnails display them and it animate great but what I'm stuck on is when clicking an image or link the content of that post/portfolio gets displayed in a new div. Ideally in place and pushing boxes out the way so if you're on a mobile you don't have to scroll to the top.
Any pointers to get me started would be great, just can't find anything like this anywhere and think it would be very useful to others :)
Thanks

Actually that can be achieved quite easily. Basically you'll merely have to add a click handler to all Isotope items. The handler has to figure out which element has been clicked (e.g. by checking class names of the clicked item, but of course there are numerous ways) and then add the respective content to your div element.
If the content has to be shown in place, it's even easier. You can simply add the preview and the full content to the same Isotope item, but hide the full content by default:
<div class="item">
<div class="preview">...</div>
<div class="full">...</div> <!-- hidden with CSS -->
</div>
Then add a click handler to all Isotope items:
$(".item").click(function(){
$(this).toggleClass("big");
$("#container").isotope("reLayout");
});
By calling .isotope("reLayout") the other items are pushed out of the way when the clicked one expands.
Finally you need some basic CSS rules making div elements with .big bigger, hiding .full by default, but showing it when .big is set in the parent div. In that case .preview has to be hidden of course; this can all be done with CSS, no JavaScript/jQuery required.
Ok, it's a bit cumbersome to explain - I guess an example says more than a thousand words: JSFiddle
Of course that's just a very basic example, but hopefully it explains what I meant. ;)

Twitter Bootstrap scrollspy always selecting last element

I have an issue with scrollspy, recreated in this fiddle:
http://jsfiddle.net/jNXvG/3/
As seen in the demo, the ScrollSpy plugin always keeps the last menu item selected no matter the scrolling position. I've read other questions and answers and tried different combinations of offset, etc., but none of them have helped. I can't figure out what's wrong.
I don't want to edit my template to include ugly html 'data' tags, so I am calling scrollspy() via JavaScript to activate the plugin.
The next step would be to remove the fixed content height and use 'affix' on the sidebar.

I had the exact same problem and for me, adding height: 100% to the body element was the fix.
(stricly nothing else seemed to make it work)

You need to attach the ScrollSpy to the element that is going to trigger scroll events, rather than the menu that is going to reflect the scroll position:
$('#content').scrollspy();​
JSFiddle

FYI: To get my desired effect (same one as on the Twitter Bootstrap docs page) I needed to set 'body' as my target element...I could not get scrollspy'ing to work by using the immediate parent of the elements I wanted to spy as the target.
(It just auto-selected the my last element always)

In my case, Firefox was always selecting the last element and it was NOT the
height:100%;
on the body that was causing the problem (as I didn't have anything like that).
It was a
position:absolute;
on a container div.
Hope it helps someone out there...

I fixed it using body height 100% but it didnt work on Firefox. After wasting so much time found the answer on github page. Applying height 100% to HTML tag fixes the issue both for Chrome and Firefox.
https://github.com/twbs/bootstrap/issues/5007

When calling the scrollspy method you typically specify the body tag and the nav element.
<script>
$(function() {
$('body').scrollspy({ target: '#faq_sidebar' });
});
</script>
The JavaScript above is equivalent to:
<body data-spy="scroll" data-target="#faq_sidebar">
The only situation where you do not specify the body tag is if you want to track an element with a nested scrollbar like in the JSFiddle above.

If anyone else's issue wasn't solved by the suggestions above try adding <!DOCTYPE html> to the first line of your page. This was a simple step which solved the problem for me.

I had this same problem; removing the height: 100% from the <body> element fixed this for me.

I had a similar issue where scroll spy would not work on anything but a body tag so I actually went into the bootstrap js found the Scroll spy (SCROLLSPY CLASS DEFINITION) section and changed this line:
, $element = $(element).is('body') ? $(window) : $(element)
to this:
, $element = $(element).is('body') ? $(window) : $(window) //$(element)
(note that the element after the // is a comment so I don't forget I changed it)
And that fixed it for me.

ScrollSpy is pretty unforgiving and the documentation is sparse to say the least...there are different and conflicting fixes for this based on your implementation...
Nested content was my problem. This fixed it for me:
(1) make sure all hrefs in your nav match a corresponding ID in your spied upon target container.
(2) If the items in your spied upon content container are nested then it won't work...
This:
<ul class="nav" id="sidebar">
<li>
<a href="#navItem1" />
</li>
<li>
<a href="#navItem2" />
</li>
</ul>
<div id="spiedContent"> <!-- nested content -->
<div id="navItem1">
<div id="navItem2"></div>
</div>
</div>
To This:
<ul class="nav" id="sidebar">
<li>
<a href="#navItem1" />
</li>
<li>
<a href="#navItem2" />
</li>
</ul>
<div id="spiedContent"> <!-- flat content -->
<div id="navItem1"></div>
<div id="navItem2"></div>
</div>
All good!
My guess if you looked at the scrollspy code its not looking past the first child of the spied container for the ids.

Make sure you're not mixing implementations. You don't need $('#content).scrollspy() if you have data-spy="scroll" data-target=".bs-docs-sidebar" on your body tag.

I think that this might be a bug in ScrollSpy.
I also had the same problem and when I stepped through the code I could see that the offset for all the targets were the same (-95px). I checked where these were being set and it was using the position() function. This returns the position of the element relative to the offset of the parent.
I changed this to use the offset() function instead. This function returns the position of the element relative to the offset of the page. Once I did this then it worked perfectly. Not sure why this isn't the default behaviour.
The reason that the position() function wasn't working in my case was because I had to have an empty div which was actually absolutely positioned 95px above the top of its container. I needed this as my target so that the headings weren't hidden behind my header that was fixed to the top of the page.

When I was trying to figure out this issue, I used some of what Mehdi Benadda said and added position: relative; to the body. I added this to the stylesheet:
body {
position: relative;
height: 100%;
}
Hopefully this helps someone in the future.

You don't have to call method scrollspy().
Also you don't need set height: 100% anywhere.
All you need is:
position: relative; for body
add data-bs-spy="scroll" to your content or body
add data-bs-target with navbar id

It helps me.

It seems that scroll spy work only when used container has a scrollbar (Tested with bootstrap 5).
You can put data-bs-spy="scroll" and data-bs-target="#target-nav" attributes in the nearest parent having a scrollbar.

In my case, i had added the scrollspy component of bootstrap version 5.2.3 but my bootstrap js cdn was 5.0. After i added the 5.2.3 js cdn, it worked!
You may also add the downladed bootstrap js files as well.
And make sure to add the bootstrap css cdn too!

jQuery Slide Toggle Not Working - Resolved

On the first click, it works as expected:
the class is changed
and the html content is changed from 'Show...' to 'Close...'
the content area is expanded with the slideDown effect,
Good so far.
On the second click, ...
the class changes
the html content is changed from 'Close...' to 'Show...'
The content area does NOT go away as expected.
On the third click, ...
the class is changed
the html content is changed
the already-shown content is re-shown with the slidedown effect.
So everything is working except for the 2nd click when the content is supposed to be hidden again.
Here's the jQuery:
-
$('.open_user_urls').live('click', function() {
$('#user_urls').slideDown('slow');
$(this).addClass('close_user_urls');
$(this).removeClass('open_user_urls');
$(this).html('Close Search History');
return false;
});
$('.close_user_urls').live('click', function() {
$('#user_urls').slideUp('slow');
$(this).addClass('open_user_urls');
$(this).removeClass('close_user_urls');
$(this).html('Show Search History');
return false;
});
Here's the HTML it's acting on:
<h3 class='open_user_urls'>Show Search History</h3>
<div id='user_urls'>
// an OL tag with content
</div>
And the only applicable CSS:
#user_urls { display: none; }
EDIT - I replaced my jquery code with functionally equivalent code supplied in an answer below, but the problem persists. So the cause must be elsewhere. I do recall this code working originally, but then it stopped. I'm stumped. Time to strip everything else out piece by piece...
EDIT 2 - Since the bug must be elsewhere, I'm accepting a code improvement for my jquery as the answer. Thanks.
Edit 3 - Found the source of the problem.
Inside the #user_urls div I have an series of OLs with the following css:
.url_list {float: left; width: 285px; list-style-position: outside; margin-left: 25px;}
Each OL contains a list of 20 urls and is meant to display in as many multiple columns as required to display all the URLs.
Removing the float: left; on these OL tags causes the problem to go away.
So having a float on the content contained in the DIV thats showing and hiding is causing it not not hide at all. Why would this happen?
EDIT 4: Adding a inside the #user_urls DIV allows the hiding action to work properly.

Perhaps something like this would be simpler?
$(".open_user_urls").toggle(
function () {
$(this).text("Close Search History").siblings(".user_urls").slideDown("slow");
},
function () {
$(this).text("Show Search History").siblings(".user_urls").slideUp("slow");
}
);
The toggle function is designed for precisely the scenario you're encountering.

To reiterate the problem and resolution to this question...
Inside the #user_urls DIV were a series of OL tags, each floated left. It was the float that was causing the problem.
Adding a <br style='clear: left;' /> inside the #user_urls DIV fixed the problem.

From what I've found, jQuery needs to have the height style set in order to slide it correctly. A work around I've used is to set the height before you slide it closed.
$('#user_urls').css('height', $('#user_urls').height() + 'px');
After you set it once, it should work correctly from then on. Check out this tutorial for a more detailed explanation.

Since this question was opened, jQuery have put in a fix for this themselves.
Updating to the latest version of jQuery solved the problem for us with no CSS changes. (jQuery 1.4.4 as of Dec 9th 2010)
Found via discussion on Google Groups in turn found from d12's answer. According to duscussion, in some jQuery 1.3x versions this bug affected several actions, slideUp, fadeOut, and toggle, if the element being hidden/slid up is a a non-floated parent containing floated children.

I think Conor's answer might put you on the right track. I might also suggest slideToggle and toggleClass:
http://docs.jquery.com/Attributes/toggleClass
http://docs.jquery.com/Effects/slideToggle
I could be as easy as:
$("h3.open_user_urls").click(function () {
next("div#user_urls").slideToggle();
});

I can't duplicate your bug. I used your exact code and I cannot replicate your issue.
This must be a script error from a different place in your JS code.

Thanks for this question. It really got me on my way figuring out the problem toggling an element with floated children.
Another resource that really helped and explains the behavior a bit can be found
on this Google group discussion.

Putting a non breaking space in your div is another solution similar to what The Reddest suggested that worked for me on a similar issue.
