This is frustrating and I can't figure this out.
I just need to change/toggle back/foreground color
for the entire body when user clicks on a link, 'theme'.
Following is my html file.
...
<style>
highlight {
background-color: black;
color: white;
}
</style>
<script>
$(document).ready(function () {
$('.theme').on('click', function () {
$(document.body).toggleClass("highlight");
//$(document.body).css({"background-color": "black"});
});
});
</script>
When I use $().css({...}), it works but when I try to use
class to be able to toggle, it doesn't. Please help.
Agree with Rayon. "highlight" in the style is not a class if missing the period in front. jQuery is not able to toggle the "highlight" class since there's no "highlight" class to toggle. The code works here: http://liveweave.com/T6c7Mz
change the following line
$(document.body).toggleClass("highlight");
with
$("body").toggleClass("highlight");
This will work
HTML
Click Me
CSS
body { background-color:red; }
.highlight
{
background-color:yellow;
}
JQUERY
$("#theme").click(function() {
$("body").toggleClass("highlight");
});
Here is the working code

I am currently trying to add a custom JS function (via the Live Code Editor Plugin) to my wordpress website. The goal is to change the background colour of a toggle after click (i.e. from red -> green). I have tried this function but although the selector works for CSS, the JS function is not working:
CSS:
\23 toggle-id-1 {
background-color: red;
}
JS:
var \23 toggle-id-1 = document.getElementById("\23 toggle-id-1");
\23 toggle-id-1.onclick = function(){
\23 toggle-id-1.style.backgroundColor = "green";
}
In JSFiddle this worked without any problems, is there anything different for this plugin?
Thank you!
jQuery solution:
$("#toggle-id-1").click(function () {
$(this).toggleClass("green");
});
#toggle-id-1 {
background-color: red;
height: 100px;
width: 100px;
}
#toggle-id-1.green { background-color: green; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="toggle-id-1" class=""></div>
You can't have spaces in variable names. Name your variable something else.
When I click on it changes background. It works fine. But what if I want to click on it again to restore the original background? I have this code:
jQuery(document).ready(function($) {
$(".select").on("click", function () {
$(this).css("background-image", "url(images/selected.png)");
});
});
Here is jsfiddle EXAMPLE
Basically when I click on the div it changes the background, which is fine. But I want to have ability to click on it again to restore the original background.
It will be an alternative solution for tick box, but just for demo purposes.
Thanks
JS
replace
$(this).css("background-image", "url(images/selected.png)");
with
$(this).toggleClass("active");
Style
#multiselect .active {
background-image: url('...');
}
Fiddle http://jsfiddle.net/09xgrhxo/4/
Instead of using .css() to change the background-image I would add a class in your CSS and use .toggleClass().
Also be aware that simply adding a class will not be specific enough because your css is using:
#multiselect .select
you're going to have to target the class you add as a child of #multiselect:
#multiselect .change
CSS
#multiselect .change{
background-image: url(http://t2.gstatic.com/images?q=tbn:ANd9GcSZ51HqKXkejWAFcSBrodHd5eUN2QaIJro0jhN1YpmljSdQ5dj2)
}
JS
$(".select").on("click", function () {
$(this).toggleClass("change");
});
FIDDLE
You could use data-* attribute.
$('.select').attr('data-img', $('.select').css('background-image'));
$(".select").on("click", function() {
$(this).css("background-image", ($(this).css('background-image') == $(this).data('img')) ? "url(http://t2.gstatic.com/images?q=tbn:ANd9GcSZ51HqKXkejWAFcSBrodHd5eUN2QaIJro0jhN1YpmljSdQ5dj2)" : $(this).data('img'));
});
#multiselect .select {
background: url(http://t0.gstatic.com/images?q=tbn:ANd9GcQF_ErOlc78eOGZaEWb-dwPkrv2uyAoKx0Pbn3-e0tAZoUDSQRCsA) center;
width: 250px;
height: 100px;
margin-bottom: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="multiselect">
<div class="select">Option1</div>
<div class="select">Option2</div>
<div class="select">Option3</div>
</div>
Instead of writing background-img url in javascrpt, I would suggest to create two classes having same properties but different background-img url which you want to toggle. so here we will be toggling class (ultimately background-img) in javascript.

I am making a html forum and am using javascript to change the colour of the forum, I have three divs, one is blue, green and red.
When each div is clicked, the javascript will change the colour of the elements.
I would like to change the colour of the submit button's focus with the .css() function in javascript, but the focus part doesn't work.
Here is my javascript code:
$("#green").click(function() {
$(".mailheader").css("background","#a3d300");
$(".submit").css("background","#a3d300");
$(".submit:focus").css("background","#98cf00");
});
$("#blue").click(function() {
$(".mailheader").css("background","#00b4ff");
$(".submit").css("background","#00b4ff");
$(".submit:focus").css("background","#04a6e9");
});
$("#red").click(function() {
$(".mailheader").css("background","#ff0000");
$(".submit").css("background","#ff0000");
$(".submit:focus").css("background","#ea0202");
});
So I have tried $(".submit:focus").css("background","#ea0202"); for chaning the background of the focus, but it doesn't work. anyone know how to fix this? thanks

$(".submit").css("background", "#ff0000");
$(".submit").focus(function () {
$(".submit").css("background", "#98cf00");
})
});
You are setting styles directly on the element. Why not set a css class on the elements and handle all the changes via css. That is much cleaner and easier to use.
eg. when '#green' is clicked add a class 'Green' to the submit button. (see http://api.jquery.com/addClass/ ) (be sure to remove the other classes)
Then in css you can set #MySubmitButton.Green{.. your green styles..} and use all the pseudo css classes you like. Things like #MySubmitButton.Green:hover {color:#FF00FF;}
Hope this helps...
jQuery can't change pseudo-elements' style
Fix (I used the .html() function for the :focus's style, using a <style> tag in the body or elsewhere):
<script>
...
$(".submit").css("background","#ff0000");
$("body style.changeColor").html("
.submit:focus {background: #ea0202};
");
...
</script>
<body>
<style class="changeColor">
</style>
</body>
And I were you, I rather change all other .css() functions into text inside the .html() string.
$("body style.changeColor").html("
...
.submit {background: #ff0000};
.submit:focus {background: #ea0202};
");
How to change the default highlight color of drop down in HTML from blue to some other color for <select><option> tags, using some CSS properties or from Javascript?
The requirement is I have to use the <select> <option> tags only. I tried the code below, but it didn't work for me:
<html>
<head>
<title>Dropdown Colour</title>
<style type="text/css">
option:hover {
background:#C6C4BD;
}
</style>
</head>
<body>
<select>
<option>Shell</option>
<option>Cabbage</option>
<option>Beans</option>
<option>Cheese</option>
<option>Clock</option>
<option>Monkey</option>
</select>
</body>
</html>
try setting outline and/or border properties of select.
select{outline:1px solid green;border:1px solid black;}
Currently there is no way I know of that this can be accomplished using only CSS.
However, using jQuery I was able to achieve a similar effect.
Live Demo
Your dropdown changes because i have to set the size of the select element which makes it look like a list-box. Maybe somebody can improvise on this.
Here is the jQuery i used
$(document).ready(function (event) {
$('select').on('mouseenter', 'option', function (e) {
this.style.background = "limegreen";
});
$('select').on('mouseleave', 'option', function (e) {
this.style.background = "none";
});
});
Try to change like this, hope it may help you
select option{
background: red;
color: #fff;
outline:1px solid green;
}
This is the simple HTML code:
<li class="main">
ImageLink <!--1st anchor tag-->
ImageName <!--2nd anchor tag-->
</li>
Is it possible to change the color of 2nd anchor tag on hover state of 1st anchor tag? (And vice versa.)
Not with css. This kind of actions can only be done by script.
If you use jQuery you could add the following script:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<script type="text/javascript>
$(document).ready(function(){
var a1 = $('a:first');
var a2 = $('a:second');
a1.hover(function(){ a2.toggleClass('hover') }, function(){ a2.toggleClass('hover') });
a2.hover(function(){ a1.toggleClass('hover') }, function(){ a1.toggleClass('hover') });
});
</script>
Now you can use the hover class to specify the color:
.hover { color: red; }
Edit
It would be easier to give both a's an id, so you could reference them by using var a1 = $('#a1');.
With CSS, it's possible to change the color of the 2nd anchor tag on hover of the 1st anchor tag with a sibling selector, but I don't think you can do it vice-versa:
a:hover + a {
color: red;
}
JSFiddle preview: http://jsfiddle.net/9Ezt5/
See http://www.w3.org/TR/CSS2/selector.html#adjacent-selectors
However, note that adjacent sibling selectors are not supported on all browsers: http://www.quirksmode.org/css/contents.html
Yes you can do it with pure css.
for example:
a:hover + a{
background:red;
}
Check this for more
http://jsfiddle.net/Bw5by/
In Jquery you can do it like this,
$("#first").hover(function(){
$('#second').css('color','red')
},function(){
$('#second').css('color','blue')
});
See it in action here,
http://jsfiddle.net/gagan/NYAHY/1/
If those are the only two links in the list item tag, then you could do something like this:
li.main:hover a
{
color: red;
}
li.main a:hover
{
color: blue;
}
Then your hovered link will be blue, and all the other ones (in this case just that other one) will be red.
