First off: I'm aware of the jQuery.css() function, but it doesn't work in my case. I'll explain why.
I have a jQuery color picker being used to change the highlighting of a website. I want to apply that color picker to the border of an element which only shows on hover.
The jQuery.css() function only applies the CSS to elements it finds, and does not work on the :hover CSS attribute.
I've tried adding a CSS class which I toggle on the hover, but it comes back to the same problem: I'm trying to change ONLY the hover value.
There's got to be a way to do this, but I've been searching StackOverflow and Google for the better part of an hour now, so I'm invoking xkcd #627
Use the hover event to achieve the same results.
$('selector').hover( function(){
//A function to execute when the mouse pointer enters the element.
$(this).css('property','value');
}, function(){
//A function to execute when the mouse pointer leaves the element.
$(this).css('property','value');
});
I'm adding this as an alternative answer.
If you need to dynamically change your CSS then there is something wrong with your CSS. It's very strange that you need a definition, that you can't toggle with a class and has to be generated dynamically.
Let's say you have a widget that can be in two modes: inactive or active. When it's active elements in it should respond visually to a hover event, when it's not, they shouldn't.
<div id="my-widget" class="my-widget-container">
<div class="element">Something to look at</div>
</div>
CSS
.my-widget-container .element { background-color: #ffffff; }
.my-widget-container.active .element:hover { background-color: #00ff00; }
You switch the mode by:
$("#my-widget").addClass("active");
This will activate the :hover line for the element which now appears interactive.
If I knew more about your situation I could perhaps fix a fitting solution.
Also, jQuery.css is poorly named, perhaps jQuery.style would be a better name since that is exactly what it does.

First, I am building a website on cargo. There's html editor but I don't think it works that well along with the site builder itself.
I want my custom image mouse cursor image change while it's on click. I've got three problems here:
I can't set my default cursor to image. (It was successful in cargo but I don't know how to do this on html editor.)
I am not sure how to change my cursor to other image.
I want this to make it happen on my whole site not just on single text or image.
Here you go!
It's quite simple to do:
Just write the cursor property to whatever Selector you want, for the whole WebSite html {...} of course.
html {
background-color: lightgray;
cursor: url("https://s3-us-west-2.amazonaws.com/s.cdpn.io/9632/happy.png"), auto;
}
<html>
</html>
There are also a lot of default cursors:
You can check them out here: https://codepen.io/chriscoyier/pen/uCwfB
I would simply use a combination of CSS and JavaScript.
CSS class declaring the appropriate cursor definition with a keyword fallback. Then add a simple onmousedown event to fire the addition of a second CSS class that declares an overriding cursor definition. Add a second onmouseout event to remove the second class that was added on click.
/* keyword fallback example: use pointer, if hand.png doesn't exist */
.cursor-hand {
cursor: url(hand.png), pointer;
}
Im looking for a way to change the background image of a div using jQuery BUT only amending it, not totally changing it.
Let me explain.
Im using http://jqueryui.com/demos/sortable/#portlets to show some div's that open and close. Now when you click the portlet header it opens and closes the content below.
Inside the portlet header i have a child div which shows an arrow (either up or down) depending on the current state of the content. I need a way of changing the background image on this child div by adding on "-visible" onto the end of the url for the background image.
I wouldnt even know where to start with doing this, but i have added some code below for you to look at.
http://jsfiddle.net/45jZU/
From the fiddle there, i need to alter the background image of the portlet-arrow div inside portlet header. I can not simply change the background image all together, but i have simplified it down to post on here.
I hope this isnt too narrow to not be of use to anyone else on stackoverflow.
Thanks
Maybe I'm missing something here, but can't you use the .css attribute modifier for the selected jQuery object? Something like:
var current_background = $("#my-div").css("background-image");
$("#my-div").css("background-image", current_background + "-visible");
If you're looking to modify the class names themselves, you can try mess around with the .toggleClass(), .hasClass(), .addClass() and .removeClass() methods in jQuery.
I hope this helps, but let me know if I've missed the mark here completely!
I would personnaly go for using css classes to change the background image. If you decide to change the image afterwards, you won't have to alter your javascript. It is a better solution to use javascript to code the behavior of the widget, not the visual aspect.
So you have the following css:
.portlet-header {
background-image: url(<an image>);
}
.portlet-header.collapsed {
background-image: url(<an other one>);
}
Add this line to your javascript to toggle the collapsed class:
$(".portlet-header").click(function() {
...
$(this).parent().toggleClass('collapsed');
});
If you widgets starts collapsed, initially add the class.

I have a link that is turned green with the a:hover CSS attribute. When I click the link, this function is triggered:
$("#comment_title_link").toggle(function() {
$(this).text('Done');
},
function(){
$(this).text('Add Comment title');
});
which changes the text of the link. The hover attribute seems to only stop being applied once you cross the border of the element that it's being applied to. However, since I change the text from "Add Comment Title" to "Done", if I have my mouse over on the word "Title" and click, "Done" appears to the left of my mouse since Done is so much shorter than Add Comment Title. Therefore, the :hover attribute is still being applied even when my mouse is not over the link. How can I remedy this issue?
One workaround would be to remove the green color styling via script within your toggle(). And when you leave and come back to hover over that text, it should turn green again.
Easiest way would be to apply hover effect via CSS only on a certain class, and remove that class after switching text:
//in css:
A.greenLink:hover
{
color: green;
}
// script:
$("#comment_title_link").toggle(function() {
$(this).text('Done')
.removeClass('greenLink');
},
function(){
$(this).text('Add Comment title');
});
Ideally, you'd want to figure out why it's happening and if there's anything you can do about it (the "right" way). But if this indeed is a browser redrawing/rendering bug, then perhaps this workaround (as ugly as it is) might help.
add a style for :active undoing the :hover (matching the normal style) when it gets click it will go to the :active style.
I have this page that does some funky database stuff that takes a couple seconds to process, and in the meantime I'd like to set a "wait" cursor so the user doesn't flip out and keep clicking the button. I've looked at the
document.body.style.cursor = "wait"
thing, the problem with this is that it only works when the mouse is over the body of the page (i.e. still shows normal pointer if it's over a button). How can I set it so that no matter where the mouse is on the page, it shows a wait icon?
A second part to this question is, once it's done it's thing, how do I set it back? If I set it back to "default", this seems to override any "hover" cursor changes I had set in my CSS (so it no longer becomes a hand when over a specified object, etc.).
EDIT: the first answer works nicely, except in IE it doesn't refresh the cursor (so you notice the change of cursor type) until you actually move the cursor. Any fixes?
What I suggest is two things:
a) Better write a CSS like
body.waiting * { cursor: wait; }
b) Use the JS to handle the body class
/* when you need to wait */
document.body.className = 'waiting';
/* to remove the wait state */
document.body.className = ''; // could be empty or whatever you want
You might want to add the class instead of replace the whole class attribute, what I suggest is to use something like jQuery for that.
EDIT 2019: don't use jQuery for just this, use classList
The styling should be handled via CSS, as stated by W3C.com:
CSS is the language for describing the presentation of Web pages, including colors, layout, and fonts. ... The separation of HTML from CSS makes it easier to maintain sites, share style sheets across pages, and tailor pages to different environments. This is referred to as the separation of structure (or: content) from presentation.
As suggested by Tom Rogerro, add a line to your CSS file:
body.waiting * { cursor: wait; }
However, your script should not overwrite the entire list of class names. Tom suggested setting the class names via jQuery, but jQuery is unnecessary in this case. Simple Javascript can do this.
To add a class name 'waiting' to the document body:
document.body.classList.add('waiting');
To remove a class name 'waiting' from the document body:
document.body.classList.remove('waiting');
For your first problem, try using cursor: wait !important;.
For your second problem, the default cursor for elements is cursor: auto;, not cursor: default; or cursor: inherit;.
If you are happy using JQuery then a quick way to solve this would be to use:
$('*').css('cursor','wait')
I don't know how elegant this is but it has been working for me,
Not an answer to the question, but a way of achieving what is wanted.
Make a div (see class below) visible when you are loading.
ensures no element is accessible and dimmed display indicates this.
you can add an animated gif to indicate something is going on instead of the cursor.
.loading{
position:fixed;
height:100%;
width:100%;
left:0;
top:0;
cursor:wait;
background:#000;
opacity:.5;
z-index:999}
Any elements that don't inherit the cursor by default (such as buttons) will need to set the cursor to inherit:
someButton.style.cursor = 'inherit';
To go back to the default for an element (and not break things like :hover with a forced cursor), set it to an empty string:
document.body.style.cursor = '';
I tried everything but finally this jquery worked, especially if you want wait cursor over all elements including buttons and links.
define at the top of angular .ts file
declare var $: any;
and then where ever you want wait cursor:
$('*').css('cursor','wait');
and remove wait:
$('*').css('cursor','auto');
To fully replace the CSS toggling behaviour, we can simply use this inline:
<img
src=https://cdn.sstatic.net/Img/unified/sprites.svg
onmouseover="this.style.cursor = 'crosshair'"
>
After you click a link on the iphone or ipad, it leaves a simulated mouse hover that triggers the a:hover css styling on that link. If the link has a javascript handler that keeps you on same page, the hover state will not change until you click on another link.
This gets weird if you have an ajax widget that asks questions and each answer is link. When you touch one of the answers, it highlights with the hover state, and then when the question and answers are replaced (using javascript) by a new question and answers, the new answer that appears in the same position as the prior answer has its hover state automatically triggered. I want to prevent that from happening to the new answer link.
Is there any way (maybe some something in javascript) that can give me the same result as the "hover" no longer being above this element?
Notes:
I know I could just have a:hover use the same css styling as a, but a:active styling is hardly noticeable since the active state of a touch click is so brief, so I'm hoping for something that can show the hover state on a link until I replace it with new html
I have tried a variety of approaches in javascript, like calling "blur()" on the dom element and some other stuff, but no luck—I'm starting to think that the best solution is to apply classes to the links on javascript events to manage the hover state myself (or just leave it as it is)
The problem is that when you replace the content in place, Mobile Safari treats the new elements as if they were the old ones, because they occupy the same position in the DOM. One workaround is to remove the old elements first, then add the new elements asynchronously. The simplest way to do this is using setTimeout().
http://jsfiddle.net/chad/JNZvu/10/
// When we click on an answer
$('body').on('click', '.answer', function(){
// don't follow it's link
event.preventDefault();
// fade out the container
$('.container').fadeOut(function(){
// remove old elements (happens after fadeOut because we are in the callback)
$('.container').html('');
// add new elements asynchronously and fade container back in.
setTimeout( '$(\'.container\').html(\'<a class="answer" href="#c">link 3</a><a class="answer" href="#d">link 4</a>\');$(\'.container\').fadeIn();', 0);
});
});
When doing this for real, the fadeOut would be called at the same time as the AJAX function, and then the removal/addition would happen in the AJAX callback.
You can try writing another :hover rule that activates when the parent has a particular class, in effect negating the existing hover rule. The class on the parent would need to be added on touchend and removed on touchstart, so that the default rule could take effect on the next link clicked or touched.
I just solved a similar problem where I want hover styling for list items, but since the parent can scroll with one finger using iscroll, I need to cancel that hover effect as soon as the scroll list moves. It's using jQuery, but you get the idea:
$('ul.scroll').bind('touchmove', function(e) {
$(this).addClass('moving');
});
$('ul.scroll').bind('touchstart', function(e) {
$(this).removeClass('moving');
});
here are my style rules:
ul.scroll li:hover {
background-color: #D1E8DA;
}
ul.scroll.moving li:hover {
background-color: #EFEFEF;
}
