Ajax Example Video

asked by AkanshaVerma

Cant find video as in? You are not able to view it or locate it? Can you please elaborate?

answered by , [ Jan, 2016 ]

In the end of 9.2( Sending data with Ajax part 2), you mentioned about some examples in the next video but there's no next example video.

answered by AkanshaVerma, [ Jan, 2016 ]

It must be related to the code files. Can you please check there and confirm?

answered by , [ Jan, 2016 ]

Yes i just did, there is no demo video for ajax after 9.2 :(

jquery installation

asked by murdulasaikeerthana

If you just want to use the library download the compressed one. If you want to study the library and create your own variant download uncompressed one.

can i have example code for simplest jquery slider

asked by rahulverma

Hi Rahul

This is for a definite interval and image size. You can also write this in a simpler code.

$(window).ready(function() {

var currentImage = 0;

//set image count
var allImages = $('#slideshow li img').length;

//setup slideshow frame width
$('#slideshow ul').width(allImages*imageWidth);

//attach click event to slideshow buttons

//increase image counter
//if we are at the end let set it to 0
if(currentImage>=allImages) currentImage = 0;
//calcualte and set position



//decrease image counter
//if we are at the end let set it to 0
if(currentImage<0) currentImage = allImages-1;
//calcualte and set position



//calculate the slideshow frame position and animate it to the new position
function setFramePosition(pos){

//calculate position
var px = imageWidth*pos*-1;
//set ul left position
$('#slideshow ul').animate({
left: px
}, 300);

var object1 = {
apple: 0,
banana: { price: 100 },
cherry: 97
var object2 = {
banana: { price: 200 },
durian: 100

// Merge object2 into object1
$.extend( object1, object2 );

Output of this would be:

Example for isArray:

Is [] an Array? <b></b>

$( "b" ).append( "" + $.isArray([]) );


Output of this would be:
Is [] an Array? true

eg : utilities

asked by naveenbagga

When we say $("div") that means you are selecting all the divs on the page. When you say $("div")[0] it means the 1st div on the page.

About Selectors

asked by MohdMonis

We would require selectors to perform any kind of js based operations. Selectors tell where is the operation to be performed. It also defines how an element should behave when under what event. So technically this will be used under all situations.
