below is my scenario
I have three classes box with randomly selected image and from array items, there is a square box002 at right lower portion, this can be drag and droppped to any of three box if it find match the box will dissappear. likwise three box will dissappear.
then a class bodyblue is added to body with backgroundImage named middle bg is added to body for 10 seconds . after again 3 box appear for drag and drop.
in the second level after this three boxes are dragged&dropped and deleted, when bodyblue is added to body the backgroundImage middle bg is not appearing in for 10 seconds.

The problem is not that you are not applying bodyblue class to body. bodyblue class is applied 2nd time also. But after 1st time, you set a background-image to body via javascript. Which is a more 'powerfull' style than with css. It has a higher priority so it overrides the styles from css in the 2nd attempt.
So you could use a more specific selector body#main.bodyblue in CSS or even !important.

adding class to body in jquery not working

I have three class boxes with a randomly selected image and from array items. There is a square box002 at right lower portion, this can be drag and dropped to any of three boxes. If it finds a match, the box will disappear, likewise, box three will disappear.
Then a class named bodyblue is added to the body with a backgroundImage named middle bg is added to body for 10 seconds. After again box three appears for drag and drop.
The problem I am having is:
In the second level after three boxes are dragged & dropped and deleted, when bodyblue is added to body the backgroundImage middle bg is not appearing in for 10 seconds.
How do I add bodyblue backgroundImage to body using jquery in second level and third level?

angular model updating and value got lost once execution complete using jquery click function?

In this example while we click on the click link:-
$scope.div_1 = true;
$scope.div_2 = true;
$scope.div_3 = true;
Am updating this value dynamical some thing like this:-
for (var i = 1; i <= 3; i++) {
if(i == parseInt(divNumber) && $scope['div_'+i] != true){
$scope['div_'+i.toString()] = true;
}
else{
$scope['div_'+i.toString()] = false;
}
}
while i debug that time model value changing properly in scope(if expand second one $scope.div_1 & $scope.div_3 become false and $scope.div_2 become true) but its not updating UI and model got lost and also value changes previous value can any one help on this...
var app = angular.module('editor', []);
app.controller('MainCtrl', function($scope) {
$scope.div_1 = true;
$scope.div_2 = true;
$scope.div_3 = true;
$("a.expansion-btn").click(function (){
classes = this.className;
var divNumber = classes.slice(-1);
var toGetId = "#div-"+divNumber;
for (var i = 1; i <= 3; i++) {
if(i == parseInt(divNumber) && $scope['div_'+i] != true){
$scope['div_'+i.toString()] = true;

While using angular always try to use the angular methods wherever possible.
you can achieve the desired functionality using ng-click. With ng-click you can pass the vent information, using which you can get the element and perform rest of the action.
var app = angular.module('editor', []);
app.controller('MainCtrl', function($scope) {
$scope.div_1 = false;
$scope.div_2 = false;
$scope.div_3 = false;
$scope.update = function(event) {
var elem = event.target;
classes = elem.className;
var divNumber = classes.slice(-1);
var toGetId = "#div-" + divNumber;
for (var i = 1; i <= 3; i++) {
if (i == parseInt(divNumber) && $scope['div_' + i] != true) {
$scope['div_' + i.toString()] = true;
} else {
$scope['div_' + i.toString()] = false;
}
}
if ($(toGetId).hasClass("expanded-div")) {
$(".normal-div").removeClass("compressed-div");
$(".normal-div").removeClass("expanded-div");
} else {
$(".normal-div").removeClass("compressed-div");
$(".normal-div").removeClass("expanded-div");
$(".normal-div").addClass("compressed-div");
$(toGetId).removeClass("compressed-div");
$(toGetId).addClass("expanded-div");
}

you can also call $scope.$apply() at the end of your JQuery function to get the similar result but angular way is more preferable.

How to build simple jQuery image slider with sliding or opacity effect?

Some of us might not want to use ready plugins because of their high sizes and possibilty of creating conflicts with current javascript.
I was using light slider plugins before but when customer gives modular revise, it became really hard to manipulate. Then I aim to build mine for customising it easily. I believe sliders shouldn't be that complex to build from beginning.
What is a simple and clean way to build jQuery image slider?

Before inspecting examples, you should know two jQuery functions which i used most.
index() returns value is an integer indicating the position of the first element within the jQuery object relative to its sibling elements.
eq() selects of an element based on its position (index value).
Basicly i take selected trigger element's index value and match this value on images with eq method.
- FadeIn / FadeOut effect.
- Sliding effect.
- alternate Mousewheel response.
​html sample:
<ul class="images">
<li>
<img src="images/1.jpg" alt="1" />
</li>
<li>
<img src="images/2.jpg" alt="2" />
</li>
...
</ul>
<ul class="triggers">
<li>1</li>
<li>2</li>
...
</ul>
<span class="control prev">Prev</span>
<span class="control next">Next</span>
OPACITY EFFECT: jsFiddle.
css trick: overlapping images with position:absolute
ul.images { position:relative; }
ul.images li { position:absolute; }
jQuery:
var target;
var triggers = $('ul.triggers li');
var images = $('ul.images li');
var lastElem = triggers.length-1;
triggers.first().addClass('active');
images.hide().first().show();
function sliderResponse(target) {
images.fadeOut(300).eq(target).fadeIn(300);
triggers.removeClass('active').eq(target).addClass('active');
}
SLIDING EFFECT: jsFiddle.
css trick: with double wrapper and use child as mask
.mask { float:left; margin:40px; width:270px; height:266px; overflow:hidden; }
ul.images { position:relative; top:0px;left:0px; }
/* this width must be total of the images, it comes from jquery */
ul.images li { float:left; }
jQuery:
var target;
var triggers = $('ul.triggers li');
var images = $('ul.images li');
var lastElem = triggers.length-1;
var mask = $('.mask ul.images');
var imgWidth = images.width();
triggers.first().addClass('active');
mask.css('width', imgWidth*(lastElem+1) +'px');
function sliderResponse(target) {
mask.stop(true,false).animate({'left':'-'+ imgWidth*target +'px'},300);
triggers.removeClass('active').eq(target).addClass('active');
}
Common jQuery response for both slider:
( triggers + next/prev click and timing )
triggers.click(function() {
if ( !$(this).hasClass('active') ) {
target = $(this).index();
sliderResponse(target);
resetTiming();
}
});
$('.next').click(function() {
target = $('ul.triggers li.active').index();
target === lastElem ? target = 0 : target = target+1;
sliderResponse(target);
resetTiming();
});
$('.prev').click(function() {
target = $('ul.triggers li.active').index();
lastElem = triggers.length-1;
target === 0 ? target = lastElem : target = target-1;
sliderResponse(target);
resetTiming();
});
function sliderTiming() {
target = $('ul.triggers li.active').index();
target === lastElem ? target = 0 : target = target+1;
sliderResponse(target);
}
var timingRun = setInterval(function() { sliderTiming(); },5000);
function resetTiming() {
clearInterval(timingRun);
timingRun = setInterval(function() { sliderTiming(); },5000);
}

Here is a simple and easy to understand code for Creating image slideshow using JavaScript without using Jquery.
<script language="JavaScript">
var i = 0; var path = new Array();
// LIST OF IMAGES
path[0] = "image_1.gif";
path[1] = "image_2.gif";
path[2] = "image_3.gif";
function swapImage() { document.slide.src = path[i];
if(i < path.length - 1) i++;
else i = 0; setTimeout("swapImage()",3000);
} window.onload=swapImage;
</script>
<img height="200" name="slide" src="image_1.gif" width="400" />

I have recently created a solution with a gallery of images and a slider that apears when an image is clicked.

PhoneGap javascript reference issue

In my PhoneGap Eclipse project I am using jQuery for visual effects by referencing jQuery libraries:
<link rel="stylesheet"
href="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery.js"></script>
<script type="text/javascript"
src="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.js"></script>
and I am also making remote domain requests in order to display some information from the remote server.
1: When I make requests to multiple servers, I get an error saying:
DroidGap: TIMEOUT ERROR! - calling webViewClient
I read that I must alter my Phonegaps whitelist by doing:
<phonegap>
<access origin="\*\" />
</phonegap>
Source: GitHub call-back
But I get some error, so I have decided to approach same results from the different ways:
2: <script type="text/javascript" src="file:///android_asset/js/jquery.js"></script>
<script type="text/javascript" src="../js/jquery.js"></script>
Why? - because i would like to avoid getting errors with multiple-domain requests
In these cases I get an error
SyntaxError: Parse error at file:///... in logcat
I have no idea why this is happening, because the specified file location supposed to be right in both cases.
So my questions are:
Why I cannot include .js file in this way?
Which solution I should continue trying to approach (1 or 2)?
