I have a page with a textbox in it. When I scroll the textbox to the bottom, the document will scroll after it. How to disable mouse scrolling for the document but enable scrolling for the textbox when mouse is over textbox? I only need to disable mouse scroll and not window scrollbars.
The page has a fixed size and there will only be scrollbars when the browser window is not maximized. The document has a 800x600 px size and should fit for most users I think.
I'm using JavaScript with jQuery.
$('#txt').hover(function (){
$('body').css('overflow','hidden');
}, function (){
$('body').css('overflow','auto');
})
You could try the following
<script type="text/javascript">
function stop()
{
return false;
}
document.onmousewheel=stop;
</script>
You could also do this in CSS if you choose to do so using the following;
body{
overflow: hidden;
}
Off the top of my head I came up with that. If you don't want them to scroll you could also add some stuff to your CSS class like the following
Hope this helps!
Happy Coding! ;)
Use the following code to disable scrolling:
if(window.addEventListener){ //Firefox only
window.addEventListener("DOMMouseScroll", function(e){e.preventDefault()}, true);
}
window.onscroll = function(e){e.preventDefault()};
For compability, see: http://www.quirksmode.org/dom/events/scroll.html
This solution is same of Sameera but without Jquery:
var azul = document.getElementById("azul");
azul.onmouseover = function(){
document.body.style.overflowY = "hidden";
};
azul.onmouseout = function(){
document.body.style.overflowY = "auto";
};
#total{
height: 900px;
}
#amarela{
background-color: yellow;
height:50%;
}
#azul{
background-color: blue;
height:50%;
}
<div id="total">
<div id="amarela"></div>
<div id="azul"></div>
</div>

I have a div containing three buttons. The div needs to be draggable, so that you can drag all three buttons around the screen together. That works fine, but the problem is that when I click on of the individual buttons it inherits the draggable id and it is draggable on it's own. I do not want that to happen. So my question is: how do I make my buttons draggable, but make them always stay together and keep them clickable. I added the code below, but here is a JSFiddle: http://jsfiddle.net/2ga50vvt/
So to be clear: the div also needs to be draggable through dragging one of the individual buttons, but then the rest of the div needs to stick with it. Now dragging an individual button only moves the button.
P.S. I do not want to use JQuery UI
HTML:
<div id="draggable" class="ui-widget-content">
<button ng-click="menu.shown = !menu.shown">MENU</button>
<br>
<button ng-click="disconnect()">CLOSE</button>
<br>
<button ng-click="">KEYS</button>
</div>
JS
$(document).ready(function() {
var $dragging = null;
$('body').on("mousedown", "#draggable", function(e) {
$(this).attr('unselectable', 'on').addClass('dragged');
var el_w = $('.dragged').outerWidth(),
el_h = $('.dragged').outerHeight();
$('body').on("mousemove", function(e) {
if ($dragging) {
$dragging.offset({
top: e.pageY - el_h / 2,
left: e.pageX - el_w / 2
});
}
});
$dragging = $(e.target);
}).on("mouseup", ".dragged", function(e) {
$dragging = null;
$(this).removeAttr('unselectable').removeClass('dragged');
});
});
CSS:
body {
padding: 50px;
}
.dragged {
background-color: yellow;
}
#draggable {
position: fixed;
width: 150px;
height 150px;
padding: 0.5em;
background: red;
background-color: black;
z-index: 1000;
cursor: move;
float: left;
}
Update 1
This is a working solution: http://jsfiddle.net/2ga50vvt/3/
However when I click on the div and start dragging the center of the div jumps to my cursor. It works great, but it looks a bit wonky. Is there a way to prevent the div from moving to my cursor?
Your help is most welcome.
You can read the target property of the event and return false to avoid all not #draggable to be draggable.
if(e.target.id !== "draggable") {
return false;
}
The edited fiddle:
http://jsfiddle.net/2ga50vvt/1/
It works perfectly, but one suggestion: don't target with ids because with this code you can't drag more of one element (ids must be unique), so the workaround is to write an attribute or a classname and play with it.
Good luck.
Use $dragging = $('#draggable'); instead of $dragging = $('e.target');
It will drag div if you try to drag using cursor on button. It will drag #draggable instead of target.

Presuming you're opposed to JQueryUI for it's file size, I'd still recommend a prebuilt solution because why reinvent the wheel?
Draggabilly is a really nifty library that I've used when resource size has been an issue. It's 20k minified (obviously even smaller gzipped) and available on a CDN - which in itself has lots of benefits e.g. caching.
$(function() {
$( "#draggable" ).draggabilly();
});
There's a few CSS hooks, different options, events etc.

I want my sidebar to have a scrollable div. But it cant have a fixed height. How can I make it scrollable without setting a fixed height?
I tried with this, doesn't work properly.
.sidebar {width:300px; padding:10px; background:#efefef;height:100%; position:fixed}
.scroll-widget {overflow-y: scroll;padding:10px;margin:10px; background:#fffeee; height:inherit}
-
<div class=sidebar>
...
<div class=scroll-widget>
...
</div>
</div>
Demo: http://jsfiddle.net/YK47P
Jquery alternative is also fine with me. But i am a beginner, so please be kind
Somehow I was able to make it work using jQuery and taking help from here.
$(function () { // window load
$(window).resize(function () {
var sidebarH = $('.sidebar').height();
var scrollH = $('.top').height();
$('.scroll-widget').height(sidebarH - scrollH);
}).resize();
});
DEMO : http://jsfiddle.net/YK47P/40/
You just need to add overflow: scroll to your sidebar:
.sidebar {
width:300px;
padding:10px;
background:#efefef;
height:100%;
position:fixed;
overflow: scroll;
}

I need to make a menu bar like the one in
http://showbic.com/sports/adam-milne-vs-west-indies/
In this website the menu_bar is not on the top, but when you scroll down the menu bar doesn't go up with the rest of the content, but after touching the top it stays at the top.
I know some JavaScript is used combined with the CSS, but how I don't know, please someone help me.
Thank You in Advance.
I would advise trying something with onscroll in Javascript and then keeping the header at the top you can use position:fixed; in the container's CSS. (you might want to play around with the top placement or something else to keep it at the very top and in your preferred spot when not needed at the top)
See for example:
<script type="text/javascript">
var fixed = false;
onscroll = function()
{
var scrollTop = document.documentElement.scrollTop || document.body.scrollTop;
if (scrollTop > 200)
{
if (!fixed)
{
$('.navbar-wrapper').css({ position: 'fixed', top : 0 });
fixed = true;
}
}
else
{
if (fixed)
{
$('.navbar-wrapper').css({ position: 'relative', top : 200 });
fixed = false;
}
}
}
</script>
When looking into the source code, you can view the javascript part that is controlling this bar. http://showbic.com/wp-content/plugins/seo-alrp/js/slidebox.js?ver=3.8.
Instead of :
$('#alrp-slidebox').animate({'right':'0px'},300);
Put:
$('#yourContent').animate({'top':'0px'},300);
And for (we suppose that the height of the box is 300px):
$('#alrp-slidebox').stop(true).animate({'right':'-430px'},100);
Put:
$('#yourContent').stop(true).animate({'top':'-300px'},100);
This can be your css
body{
height:1000px;
}
div{
width:200px;
height:100px;
background:red;
position:relative;
top:200px;
}
.fixedClass{
position:fixed;
top:0;
}
the jquery code
$(window).scroll(function(){
if($(window).scrollTop() > 200){ // position of menu from the top
$('div').addClass('fixedClass');
}
else{
$('div').removeClass('fixedClass');
}
})
the Html :P

+++++i add mention+++++
thanks guys for your answers,
but, i think, i missed something to write more.
when i click the button to show the div(#pop), it works right at the scroll on the top.
but, when i go down the scroll, the div(#pop) goes up in the window(height:0) not in "bottom:10%" like at the scroll on the top.
so, i'm trying your answers now, but, i'm not succeed yet T_T HELP!! :)
=================================================================================
Here are my codes.
I have a floating menu and one button of them works for showing a div id = pop, which is floating too.
I want to hide the div #pop when window starts, and when the button's clicked, it shows.
So I added codes display:none to hide, but when i click the button to show the div #pop, the div #pop is anywhere, not in bottom: 10% in CSS.
HTML
<div class="menu">
<img src="btnUp.png"><br/>
<img src="btnMe.png" id="pop_bt"><br/>
<a href="#scrollbottom">
<img src="btnDown.png">
</a>
</div>
<div id="pop">
<div>
POP UP
</div>
</div>
CSS
#pop{
display: none;
width: 300px;
height: 400px;
background: #3d3d3d;
color: #fff;
position: absolute;
bottom :10%;
left: 30%;
z-index: 3;
}
Javascript
$(document).ready(function(){
var boxtop = $('.menu').offset().top;
$(window).scroll(function(){
$('.menu').stop();
$('.menu').animate({"top": document.documentElement.scrollTop + boxtop}, 800);
});
});
$(document).ready(function() {
$('#pop_bt').click(function() {
$('#pop').show();
});
$('#pop').click(function() {
$('#pop').hide();
});
});
$(document).ready(function(){
var boxtop = $('#pop').offset().top;
alert(boxtop);
$(window).scroll(function(){
$('#pop').stop();
$('#pop').animate({"top": document.documentElement.scrollTop + boxtop}, 800);
});
});
Actually, I'm not a programmer, just a designer, so I'm very fool of HTML/CSS/Javascript.
Can anyone help me?
Display none is removing your button from the layout.
Same on .hide().
Use opacity 0 to hide the dig but keep it in your browser.
In the absence of a fiddle, I can do some guess work only. Looks like the line below is the problem:
$('#pop').animate({"top": document.documentElement.scrollTop + boxtop}, 800);
It sets a top value and moves the layer to some other place. It should work fine if you remove that.
use this...
$(document).ready(function()
{
$("#pop").hide();
$("#button_id").click(function()
{
$("#pop").show();
});
});
is this you actually need?
I haven't been able to find the answer to this anywhere.
How do you make a hidden div appear when mousing over where it would have been?
Please do not tell me how to make a link, I know how to make a link ;)
I have tried:
a.) onmouseover set visibility to visible and onmouseout set visibility to hidden
this works in 0 browsers
b.) setting borders to 0px and background transparent and innerhtml to "" onmouseout and reverting onmouseover
this works in chrome
c.) This was the most popular answer on the internet, which i knew wouldn't work, but I tried anyway: make a container div set to visible and then do visibility visible and visibility hidden for the inner div
d.) Setting opacity to 1/100 and 0
works in chrome
e.) last resort: i tried making a transparent gif and having it display onmouseout
this also failed
I haven't tried jquery's .hover but I have read that it may not work correctly.
I have no other ideas. Will somebody help, please?
If I get it right you want div element to show if you are over it and hide when the mouse is not over. If that's it you can do it only with html and css:
<head>
<style>
#outerDiv{width:100px;height:100px;background-color:blue;}
#innerDiv{width:100px;height:100px;background-color:red;display:none;}
#outerDiv:hover #innerDiv {display:block;}
</style>
</head>
<html>
<div id="outerDiv">
<div id="innerDiv">some text</div>
</div>
</html>
The outer div is always visible and when it's hovered the inner one is shown.
I think that this is going to help you: http://jsfiddle.net/eb4x9/
The mouseover event won't trigger when the div is hidden so you can detect it's position and size.
Here is the source:
HTML
<div id="foo"></div>
CSS
#foo {
width: 300px;
height: 300px;
background-color: red;
visibility: hidden;
}
JS
$(document).mousemove(function (event) {
var div = $('#foo'),
divLeft = div.offset().left,
divTop = div.offset().top,
divWidth = div.width(),
divHeight = div.height();
if ((event.pageX >= divLeft && event.pageX <= divLeft + divWidth) &&
(event.pageY >= divTop && event.pageY <= divTop + divHeight)) {
div.css('visibility', 'visible');
} else {
div.css('visibility', 'hidden');
}
});
$(document).mouseleave(function (event) {
var div = $('#foo');
div.css('visibility', 'hidden');
});
Best regards!
Try setting the display attribute of the div to 'block' along with the visibility attribute to 'visible' in your onmouseover event.
Set the display to 'none' and visibility to 'hidden' to hide.
Of course the trouble will be firing the mouse over on a hidden div.
This works in every browser I have ever used it in.
Try this, having two divs one empty and other with your content and toggling between them on mouseover
<html>
<head>
<script>
function toggle() {
var your_div = document.getElementById("your_div");
var empty_div = document.getElementById("empty_div");
if(your_div.style.display == "block") {
your_div.style.display = "none";
empty_div.style.display = "block";
}
else {
your_div.style.display = "block";
empty_div.style.display = "none";
}
}
</script>
<style>
#empty_div{width:100px; height:100px;}
#your_div{width:100px; height:100px; border: 1px solid #000fff;}
</style>
</head>
<body>
<div id="your_div" onmouseover="toggle()">xyz</div>
<div id="empty_div" onmouseover="toggle()"></div>
</body>
</html>
