body{
background-image: "image.jpg";
}
How can I change the background image suppose 'image1.jpg,image2.jpg...'
after 5s.
Found this script on StackOverflow for changing the image, but I also need to change it after few seconds and also Without Click
<script type="text/javascript">
$(document).ready(function() {
$('body').css('background-image', 'url("image2.jpg")');
});
</script>
put your urls or img path inside the array, it will loop through every image. started with first one.
use setInterval if you need this keep running forever. (setTimeout will run once per call)
$(document).ready(function() {
var urls = ['https://pp.userapi.com/c629327/v629327473/db66/r051joYFRX0.jpg', 'https://www.codeproject.com/KB/GDI-plus/ImageProcessing2/img.jpg', 'https://img.wikinut.com/img/gycf69_-6rv_5fol/jpeg/0/Best-Friends-Img-Src:Image:-FreeDigitalPhotos.net.jpeg', 'http://www.travelettes.net/wp-content/uploads/2014/03/IMG_3829-Medium-600x400.jpg'];
var cout = 1;
$('body').css('background-image', 'url("' + urls[0] + '")');
setInterval(function() {
$('body').css('background-image', 'url("' + urls[cout] + '")');
cout == urls.length-1 ? cout = 0 : cout++;
}, 5000);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
you can also use a CSS animation:
body {
background:url(http://lorempixel.com/400/400/people/1);
animation: chbg 15s infinite alternate;
background-size:cover
}
#keyframes chbg {
0% {
background:url(http://lorempixel.com/100/100/people/1);
background-size:cover
}
20% {
background:url(http://lorempixel.com/100/100/people/7);
background-size:cover
}
40% {
background:url(http://lorempixel.com/100/100/people/6);
background-size:cover
}
60% {
background:url(http://lorempixel.com/100/100/people/2);
background-size:cover
}
80% {
background:url(http://lorempixel.com/100/100/people/9);
background-size:cover
}
100% {
background:url(http://lorempixel.com/100/100/people/8);
background-size:cover
}
}
do you mean something like this . You can fill the array of colours with image paths!
var counter=0;
var colours=["red","green","blue"];
$(function() {
change();
function change() {
setTimeout(change,5000);
$('body').css('background-color', colours[counter] );
counter++;
if(counter==3){ counter=0;}
}
});

Easy Way To Do Is That with Function run code to chek
function run(interval, frames) {
var int = 1;
function func() {
document.body.id = "b"+int;
int++;
if(int === frames) { int = 1; }
}
var swap = window.setInterval(func, interval);
}
run(1000, 10); //milliseconds, frames
#b1 { background: hsl(0, 50%, 50%); }
#b2 { background: hsl(30, 50%, 50%); }
#b3 { background: hsl(60, 50%, 50%); }
#b4 { background: hsl(90, 50%, 50%); }
#b5 { background: hsl(120, 50%, 50%); }
#b6 { background: hsl(150, 50%, 50%); }
#b7 { background: hsl(180, 50%, 50%); }
#b8 { background: hsl(210, 50%, 50%); }
#b9 { background: hsl(240, 50%, 50%); }
#b10 { background: hsl(270, 50%, 50%); }

I have an Angular SPA, which loads a bunch of data from the backend and displays them in, let's say tables. In order to provide a better user experience, I'm hiding those tables while the data is loaded and display a spinner. So I end up writing code like this:
Template:
<div class="row">
<div class="col-md-12">
<spinner ng-show="ctrl.loading.unicorns"></spinner>
<ul ng-hide="ctrl.loading.unicorns">
<li ng-repeat="unicorn in ctrl.unicorns">{{ unicorn.name }}</li>
</ul>
</div>
</div>
Controller:
function unicornController() {
var ctrl = this;
ctrl.loading = {
unicorns: true
};
unicornService
.get()
.then(function(data) {
ctrl.unicorns = data;
})
.finally(function() {
ctrl.loading.unicorns = false;
});
return ctrl;
}
With one loader it's not a big deal, but when I have 3 of them in every view, it feels like the loading could be handled in a better way. I found out that promises have a $$state.status property which holds exactly this value, but afaik I should not use that as it's not part of the public API. Is there any other way to achieve this without messing around local flags?
You can either find a way to do it yourself or you can find an existing way to do it.
Here is a usefull projects that will automatically display the progress of your $http requests.
Angular loading bar
Install (npm or bower)
$ npm install angular-loading-bar
$ bower install angular-loading-bar
Include
angular.module('myApp', ['angular-loading-bar'])
If you are doing it a lot and you need to have independent loader maybe it is good idea to implement specific directive/component just for that?
Simple example with spinKit spinner.
angular.module('app', []);
angular.module('app').component('loading', {
transclude: true,
template: `
<div class="spinner" ng-show="$ctrl.loading"></div>
<ng-transclude ng-hide="$ctrl.loading"></ng-transclud>
`,
bindings: {
promise: '<'
},
controller: function() {
this.loading = false;
this.$onChanges = function() {
if (this.promise != null) {
this.loading = true;
this.promise
.then(function() {
this.loading = false;
}.bind(this));
}
}.bind(this);
}
});
angular.module('app').controller('Example', function($timeout) {
this.emitPromise = function(propName) {
this[propName] = createRandomPromise()
.then(function(result) {
this[propName + 'Result'] = result;
}.bind(this));
}.bind(this);
function createRandomPromise() {
var time = Math.round(Math.random() * 3000); // up to 3s
return $timeout(function() {
return time;
}, time);
}
});
.spinner {
width: 40px;
height: 40px;
background-color: #333;
margin: 10px auto;
-webkit-animation: sk-rotateplane 1.2s infinite ease-in-out;
animation: sk-rotateplane 1.2s infinite ease-in-out;
}
#-webkit-keyframes sk-rotateplane {
0% {
-webkit-transform: perspective(120px)
}
50% {
-webkit-transform: perspective(120px) rotateY(180deg)
}
100% {
-webkit-transform: perspective(120px) rotateY(180deg) rotateX(180deg)
}
}
#keyframes sk-rotateplane {
0% {
transform: perspective(120px) rotateX(0deg) rotateY(0deg);
-webkit-transform: perspective(120px) rotateX(0deg) rotateY(0deg)
}
50% {
transform: perspective(120px) rotateX(-180.1deg) rotateY(0deg);
-webkit-transform: perspective(120px) rotateX(-180.1deg) rotateY(0deg)
}
100% {
transform: perspective(120px) rotateX(-180deg) rotateY(-179.9deg);
-webkit-transform: perspective(120px) rotateX(-180deg) rotateY(-179.9deg);
}
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular.js"></script>
<div ng-app="app" ng-controller="Example as Ex">
<loading promise="Ex.x">
x result = {{Ex.xResult}}
</loading>
<br>
<button type="button" ng-click="Ex.emitPromise('x')">emit x</button>
<br>
<loading promise="Ex.y">
y result = {{Ex.yResult}}
</loading>
<br>
<button type="button" ng-click="Ex.emitPromise('y')">emit y</button>
</div>
Or if you wish you can use directive to insert result to transcluded scope:
angular.module('app', []);
angular.module('app').directive('loading', function($parse) {
return {
restrict: 'E',
transclude: true,
scope: true,
template: `
<div class="spinner" ng-show="loading"></div>
<div class="target" ng-hide="loading"></div>
`,
link: function($scope, $element, $attrs, $ctrl, $transclude) {
$scope.loading = false;
var targetElem = angular.element($element[0].querySelector('.target'));
$scope.$watch(watchFn, function(promise) {
if (promise != null) {
$scope.loading = true;
promise.then(function(result) {
$scope.loading = false;
$scope.result = result;
$transclude($scope, function (content) {
targetElem.empty();
targetElem.append(content);
});
});
}
});
function watchFn() {
return $parse($attrs.promise)($scope);
}
}
};
});
angular.module('app').controller('Example', function($timeout) {
this.parentValue = 'parent Value';
this.emitPromise = function(propName) {
this[propName] = createRandomPromise();
}.bind(this);
function createRandomPromise() {
var time = Math.round(Math.random() * 3000); // up to 3s
return $timeout(function() {
return time;
}, time);
}
});
.spinner {
width: 40px;
height: 40px;
background-color: #333;
margin: 10px auto;
-webkit-animation: sk-rotateplane 1.2s infinite ease-in-out;
animation: sk-rotateplane 1.2s infinite ease-in-out;
}
#-webkit-keyframes sk-rotateplane {
0% {
-webkit-transform: perspective(120px)
}
50% {
-webkit-transform: perspective(120px) rotateY(180deg)
}
100% {
-webkit-transform: perspective(120px) rotateY(180deg) rotateX(180deg)
}
}
#keyframes sk-rotateplane {
0% {
transform: perspective(120px) rotateX(0deg) rotateY(0deg);
-webkit-transform: perspective(120px) rotateX(0deg) rotateY(0deg)
}
50% {

Hello guys it's been bugging me all night. I've been trying to get together a word rotate feature that decreases in speed and then eventually stops. Think of it like a word roulette. So i have the words stored in an array and it looks over the words and displays them. Now, i need to decelerate the speed and slowly make it stop and a random lettter, how would i go about this ?
<?php
$json=file_get_contents('http://ddragon.leagueoflegends.com/cdn/5.18.1/data/en_US/champion.json');
$champions = json_decode($json);
?>
<?php
$championsArray = array();
foreach($champions->data as $champion){
$championsArray[] = $champion->id;
}
shuffle($championsArray);
$speed = 1000;
$count = count($championsArray);
var_dump($championsArray);
?>

Can anyone figure out a solution for this?
You could modify a bit the wordrotator plugin so that it allows to change the speed on each rotate.
You'll have to tweak the animation and the speed increment, but this should give you some ideas:
(function ($) {
$.fn.wordsrotator = function (options) {
var defaults = {
autoLoop: true,
randomize: false,
stopOnHover: false,
changeOnClick: false,
words: null,
animationIn: "flipInY",
animationOut: "flipOutY",
speed: 40,
onRotate: function () {},//you add these 2 methods to allow the effetct
stopRotate: function () {}
};
var settings = $.extend({}, defaults, options);
var listItem
var array_bak = [];
var stopped = false;
settings.stopRotate = function () {//you call this one to stop rotate
stopped = true;
}
return this.each(function () {
var el = $(this)
var cont = $("#" + el.attr("id"));
var array = [];
//if array is not empty
if ((settings.words) || (settings.words instanceof Array)) {
array = $.extend(true, [], settings.words);
//In random order, need a copy of array
if (settings.randomize) array_bak = $.extend(true, [], array);
listItem = 0
//if randomize pick a random value for the list item
if (settings.randomize) listItem = Math.floor(Math.random() * array.length)
//init value into container
cont.html(array[listItem]);
// animation option
var rotate = function () {
cont.html("<span class='wordsrotator_wordOut'><span>" + array[listItem] + "</span></span>");
if (settings.randomize) {
//remove printed element from array
array.splice(listItem, 1);
//refill the array from his copy, if empty
if (array.length == 0) array = $.extend(true, [], array_bak);
//generate new random number
listItem = Math.floor(Math.random() * array.length);
} else {
//if reached the last element of the array, reset the index
if (array.length == listItem + 1) listItem = -1;
//move to the next element
listItem++;
}
$("<span class='wordsrotator_wordIn'>" + array[listItem] + "</span>").appendTo(cont);
cont.wrapInner("<span class='wordsrotator_words' />");
cont.find(".wordsrotator_wordOut").addClass("animated " + settings.animationOut);
cont.find(".wordsrotator_wordIn").addClass("animated " + settings.animationIn);
settings.onRotate();//this callback will allow to change the speed
if (settings.autoLoop && !stopped) {
//using timeout instead of interval will allow to change the speed
t = setTimeout(function () {
rotate()
}, settings.speed, function () {
rotate()
});
if (settings.stopOnHover) {
cont.hover(function () {
window.clearTimeout(t)
}, function () {
t = setTimeout(rotate, settings.speed, rotate);
});
};
}
};
t = setTimeout(function () {
rotate()
}, settings.speed, function () {
rotate()
})
cont.on("click", function () {
if (settings.changeOnClick) {
rotate();
return false;
};
});
};
});
}
}(jQuery));

if (el.fireEvent) {
el.fireEvent('on' + etype);
