Drag a div from a static handle - javascript

I want to make a div draggable with Javascript/JQuery. However, for reasons that I don't think are worthed explaining, I want in draggable from another div.
It happens that this other div (the handle), must not move, as is has the size of the screen and the objective is for it to alays stay covering the whole page.
I can't seem to find an situation like this, which is strange... Is this such a stupid question?
Anyway, can someone tell me how to do this? Thanks for the help in advance.

Have you tried applying the stoppropogation function to the drag event handler of the parent div?

I gonna put an example here , if you want more explanation, comment please.
HTML CODE:
<div style="width:1024px: height:768px" id="content"> <!-- this css is only an example -->
<div class="child" style="width:100px;height:100px;border: 1px solid black"></div>
</div
JS CODE:
$(document).ready(function(){
$(".child").draggable();
});
note: Use jquery.js and jqueryUI.js

IE contenteditable div selection

So I've been trying to make my newer website complaint for all browsers while reducing lag for an input. I made a div as the container that is contenteditable and each line as its own div and acts as a line. This works great for every browser but IE here's an example of the issue: IE selection resize. I do not want to make each line contenteditable because doing so will not allow the user to highlight more than one line of text. My code looks like this:
<div contenteditable>
<div class='inner'>BLA BLA</div>
<div class='inner'>BLA BLA</div>
</div>
All help is appreciated, if I didn't specify well enough please comment.
Any way, if u want to change that, youre talking about styles, this is the way you can handle the styles:
[contenteditable="true"]:active,
[contenteditable="true"]:focus{
border:none;
outline:none;
}
maybe this can fix ur issue, give it a try

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!

Container div over its content

I've got this HTML. Flash# divs are for flash objects (swfobjects). There is a container div container2 which I want to place it over its content, like a curtain when flash objects are updated and rebuilt to prevent the user from clicking them.
//rest of html code
<div id="container2">
<div id="flash1"></div>
<div id="flash2"></div>
<div id="flash3"></div>
<div id="flash4"></div>
</div>
//rest of html code
I've tried an absolute positioned div over the flash divs to achieve this but this doesn't work with jQuery slidetoggle effect which I use in a previous div (it has a weird width behaviour that narrows the page) therefore I've decided to try this different approach, which also seems to be more efficient.
Any idea of how to achieve this? I'm open mainly to jQuery but also to strict Javascript or whatever.
Delete div when slide up.
Add div when slide down.
Good luck =)
For me you have to add another div inside the container and use it to overlay the flash objs. Leave the container in position:relative and overflow:hidden and use a div child to cover the content!

I eventually follow the workaround proposed by mkk. This is to completely delete any applied rule to the slid div and have just worked for me.
Simple but effective.

Div not showing scrollbars with jScrollPane

Apologies if this question has already been asked, but I'm struggling to find an answer on SO.
I'm using jQuery jScrollPane on a div. I can tell the plugin has been linked correctly as the standard browser scroll bar is removed, but no jScrollPane scrollbar is added in replacement, I just can't scroll down the content..
My markup is as simple as:
<div class="classa">
...Long content here...
</div>
Javascript:
$(document).ready(function(){
$(".classa").jScrollPane();
});
Has anyone experienced this before? Is there something simple I'm missing?
I think I might be missing some CSS somewhere or something, otherwise I don't know how to specify the colour of the scrollbar anyway...
Your help would be much appreciated
There is some sample CSS code for the jScrollPane example at this URL: http://www.kelvinluck.com/assets/jquery/jScrollPane/basic.html.
The sample CSS can be found at:
http://www.kelvinluck.com/assets/jquery/jScrollPane/styles/jScrollPane.css
Hope that helps.
My mistake - that CSS is to be used with an older version of jScrollPane. The correct CSS to use can be found here: http://jscrollpane.kelvinluck.com/style/jquery.jscrollpane.css
try enclosing the ".... long content here....." in the tag.
like so:
<div class="classa">
<p>
...Long content here...
</p>
</div>

slide effect with jquery

I'd like to create a slide effect using jQuery. I have several div's:
<div id='div_1'>content currently displayed</div>
<div id='div_2' style="display:none">content to be loaded</div>
<div id='div_3' style="display:none">content to be loaded</div>
The idea is that div_2 appears while sliding and "pushing" div_1 out of sight, a little like scrolling a window (horizontal or vertical). I think I can't use actual scrolling because the divs' content is loading via ajax, so I can't position it precisely before it's loaded.
Any idea?
TIA
greg
You mean like this:
$('#div_2').slideDown('slow', function(){
$('#div_1').slideUp('slow');
});
See the working demo here.
Greg, it sounds like you are looking for something like I have done here:
http://jsfiddle.net/2E5Qv/
If so, what you want to do is to contain all of those <div>s inside a parent, and then when you want to slide them, animate the top of each div up the correct number of pixels. The solution I provided above has each <div> more or less set to a fixed height of 20px (via line-height).
The parent <div> acts as a sort of window to show only the current content.
I took what Sarfraz provided and modified it slightly based on what I think you were looking for. For the sake of the demo, I also made it fire on the click event. You can find the working example here: http://jsbin.com/emowu3/3
$('#div_1').click(function(){
$('#div_1').slideUp('slow');
$('#div_2').slideDown('slow');
});
$('#div_2').click(function(){
$('#div_2').slideUp('slow');
$('#div_3').slideDown('slow');
});
$('#div_3').click(function(){
$('#div_3').slideUp('slow');
$('#div_1').slideDown('slow');
});
