Changing CSS via JS - javascript

How can i change the "background-image" on .btn-1 to the variable "color" that i have on the script?
I basically want to change the 3color gradient property of the CSS .btn-1 using JS.
<style>
.btn {
flex: 1 1 auto;
margin: 10px;
padding: 30px;
text-align: center;
text-transform: uppercase;
transition: 0.5s;
background-size: 200% auto;
color: white;
/* text-shadow: 0px 0px 10px rgba(0,0,0,0.2);*/
box-shadow: 0 0 20px #eee;
border-radius: 10px;
}
.btn:hover {
background-position: right center;
}
.btn-1 {
background-image: linear-gradient(to right, #f6d365 0%, #fda085 51%, #f6d365 100%);
}
</style>
<body>
<div class="container">
<script>
var color = {background-image: linear-gradient(to right, color1 0%, color2 51%, color3 100%)}
</script>
<a name="button" class="btn btn-1">Button Text</a>
</div>
</body>


var color needs to be a string, select the element you want using document.querySelector then apply the gradient with element.backgroundImage = color
var color = 'linear - gradient(to right, color1 0 % , color2 51 % , color3 100 % )'
document.querySelector('.btn.btn-1').backgroundImage = color;
.btn {
flex: 1 1 auto;
margin: 10px;
padding: 30px;
text-align: center;
text-transform: uppercase;
transition: 0.5s;
background-size: 200% auto;
color: white;
/* text-shadow: 0px 0px 10px rgba(0,0,0,0.2);*/
box-shadow: 0 0 20px #eee;
border-radius: 10px;
}
.btn:hover {
background-position: right center;
}
.btn-1 {
background-image: linear-gradient(to right, #f6d365 0%, #fda085 51%, #f6d365 100%);
}
<div class="container">
<a name="button" class="btn btn-1">Button Text</a>
</div>


I would recommend you to add a modifier class for btn class. Modifier class is a part of BEM methodology and it is a sort of helper class which used to change behavior or appearance of the element. Read more about BEM.
After you added your modifier class just add it to your element when you need it.
This approach is better in terms of code cleanness and maintenance. Let me know if you have any questions.
Quick example:
.btn {
flex: 1 1 auto;
margin: 10px;
padding: 30px;
text-align: center;
text-transform: uppercase;
transition: 0.5s;
background-size: 200% auto;
color: white;
/* text-shadow: 0px 0px 10px rgba(0,0,0,0.2);*/
box-shadow: 0 0 20px #eee;
border-radius: 10px;
}
.btn:hover {
background-position: right center;
}
.btn-1 {
background-image: linear-gradient(to right, #f6d365 0%, #fda085 51%, #f6d365 100%);
}
.btn-1--extra {
background-image: linear-gradient(to right, color1 0%, color2 51%, color3 100%);
}
<body>
<div class="container">
<a name="button" id="button" class="btn btn-1">Button Text</a>
</div>
<script>
var button = document.getElementById("button");
button.classList.add("btn-1--extra");
</script>
</body>

Cookie Bar not locally displaying

Hi there I'm currently making a simple cookie bar however, I'm having issues testing this locally. So far I've tested this in JS.Fiddle here and seems to works as I would like it to.
I have checked and also have jquery-2.2.4.min.js added to the file in order for this to work.
Here is what I'm working with.
var clearCookie = function () {
var result = $.removeCookie('JSFiddleCookieNotification');
if (result) {
alert('Cookie removed, please reload.');
} else {
alert('Error: Cookie not deleted');
}
}
var closeCookie = function () {
$("#notification").toggle("slide", {
direction: "down"
});
$.cookie('JSFiddleCookieNotification', 'Notified', {
expires: 7
});
}
// Bind the buttons
$("#clearCookie").on("click", clearCookie);
$("#closeCookie").on("click", closeCookie);
// Now display the cookie if we need to
if ($.cookie('JSFiddleCookieNotification') == null) {
$("#notification").effect({
effect: "slide",
direction: "down",
duration: 600
});
}
.hidden {
display:none;
}
.cookie {
bottom: -20px;
}
.cookie-wrapper {
font-size: 12px;
font-family: Arial, Helvetica, sans-serif;
line-height: 150%;
padding: 15px 45px 30px 15px;

</div>
<div id="notification" class="cookie-wrapper cookie hidden">
<p>This site uses cookies! <a id="closeCookie" class="btn" href="#">Close</a>
</p>
</div>

According to cookie specs, only domains specified with two or three periods can be used to set the cookie.
That means, that it won't work on localhost.
For example example.com and subdomain.example.com will work, because they fulfill requirements according to cookie specs, while localhost doesn't.
Try with workaround by masking your local environment by setting some domain name in hosts file.
See:
https://curl.haxx.se/rfc/cookie_spec.html (under 'domain')

Create a DIV onclick

I have a div and a button which are laid out fine. When I click the button, how can I make the same div spawn again and again. I have tried adding an onclick function but I do not know how I would implement adding the div to it.
HTML
<div class="note" contenteditable="true">
<span id='close' contenteditable='false' onclick='this.parentNode.parentNode.removeChild(this.parentNode)'>
<img src="images/close.png" height="25" width="25" align="right" style="vertical-align: top; float: right"/>
</span>Keep clicking this text to select
</div>
<a href='#' class='button'>Create Note</a>
Javascript
<script type="text/javascript">
$(function() {
$(".note").resizable();
$(".note").keyup(function() {
$(this).css('height', '100%');
});
$(".note").draggable()
.click(function() {
$(this).draggable({
disabled: false

Here is a simple example of how you can use jQuery accomplish what it is you're trying to do. Obviously this is not exactly tailored to your needs, but will give the basis for you to learn how it might work. You're likely going to want to look at the jQuery Clone method and jQuery AppendTo method.
CSS
.note {
margin-bottom: 10px;
background-color: yellow;
width: 100px;
height: 100px;
}
jQuery
$(function() {
$('button').on('click', function() {
$('.note:last').clone().appendTo('.wrapper');
});
});
HTML
<div class="wrapper">
<div class="note">Content in div</div>
</div>
<button>Add note</button>
JSFiddle Example

Do you mean something like this?
$(window).ready(function(){
$('.button').click(function(e){
e.preventDefault();
var html = $('.template').html();
$('#notes').append('<div style="position:relative;">'+html+'<div>');
});
})
.note img{
position:relative;
position: absolute;
top: 0px;
right: 0px;
}
.button {
position: fixed;
top: 160px;
margin-left: 44%;

Css/javascript position

Well, this is my problem:
I need the red box behind the number , not above.
My css:
[data-counter]:after {
background-color: #FF6969;
background-image: -webkit-linear-gradient(#FF6969 0%, #ff0000 100%);
background-image: -moz-linear-gradient(#FF6969 0%, #ff0000 100%);
background-image: -o-linear-gradient(#FF6969 0%, #ff0000 100%);
background-image: -ms-linear-gradient(#FF6969 0%, #ff0000 100%);
background-image: linear-gradient(#FF6969 0%, #ff0000 100%);
height: 8px !important;
margin-top: 4px;
content: attr(data-counter);
top: -10px;
position: absolute;
padding: 1px 4px;
box-shadow: 0 1px 2px rgba(0,0,0,.5), 0 1px 4px rgba(0,0,0,.4), 0 0 1px rgba(0,0,0,.7) inset, 0 10px 0px rgba(255,255,255,.11) inset;
background-clip: padding-box;
font:bold 10px "Helvetica Neue", sans-serif;
color: white;
text-decoration: none;
text-shadow: 0 -1px 0 rgba(0,0,0,.6);
margin-left: -10px;
}​
My javascript(lol)
$(function () {
$('head').append('<style>#numberMps {display:none !important; }#sizeMps { color: red; width: 5px; margin-left: -7px; } </style>');
$('#inbox_link').prepend('<div id="numberMps"></div>');
var newMPs = ".main-content .statused .tcl.tdtopics:has(img[src='http://illiweb.com/fa/empty.gif?NEW']) a[href*='/privmsg?folder=inbox&mode=read&p']";
$('#numberMps').load('privmsg?folder=inbox ' + newMPs, function () {
$('#numberMps').after('<div id="sizeMps"></div>');
var sizeMPs = $('#numberMps a').size();
if (sizeMPs == '0') return;
$('li a[href^="/privmsg?folder=inbox?BOX"]').attr('data-counter', ''+sizeMPs+'');
});
});
Look, the javascript obatin the number of messages, and the css draw this.
Anyone have tips or a solution?

Try useing z-index, it should help.

jQuery ajax load function doesn't include custom javascript file

I have made a custom jquery popupbox for "Tell a friend" application on my website. It uses the jQuery load function to include a php file from Modules folder and display it into the popupbox. The CSS Works fine but when I bind Javscript to it, It doesn't work at all.
The code below popups the "Tell a friend Form from module folder"
/* Popup for Email to a friend*/
$("#emailtoafriend").click(function (){
$("#overlay").removeClass("overlayHide");
$("#overlay").addClass("overlayShow");
$("#overlay").fadeIn("slow");
$("#popup").load('modules/mod_tellafriend/default.php');
return false;
});
This code below, fires off when a user clicks on the Close Button. This doesn't work
$(".btnClose").click(function (){
alert("Works");
$("#overlay").fadeOut("slow");
$("#overlay").removeClass("overlayShow");
$("#overlay").addClass("overlayHide");
return false;
});
And below is the CSS am using on this popupbox
.overlay{
width: 100%;
height: 100%;
position: absolute;
}
.overlayHide{
display: none;
}
.overlayShow{
display: block;

What's wrong?
Why does CSS works fine and JavaScript doesn't. All my Javascripts are being loaded in the bottom of the page (Not on the head).

$.load can't load jsfile or javascript.
you can put the jsfile in parent page who call load ;
and put js in $.load function ,like:
$("#popup").load('modules/mod_tellafriend/default.php',function(){
//javascript
});
