A guide on using jQuery to iterate through 3 separate div elements

Seeking assistance with creating a dynamic loop for multiple divs (3 or more) using jQuery. The desired outcome is to have the main image div on the homepage rotate with other divs, changing both the background image and links within each div.

I initially achieved this effect by stacking CSS and fading images behind, but now I need the links within the divs to update as well.

Below is the HTML for the section:

<head>
<title>Sample</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="bootstrap.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="jquery-1.11.0.min.js"></script>
<script type="text/javascript" src="jquery.leanModal.min.js"></script>
<link type="text/css" rel="stylesheet" href="index.css" />
</head>

The Div that needs to change:

<div class="jumbotron-1">
<div class="container">
<h1>What We Are</h1>
<p> A Paragraph</p> 
<div class="divbutton">
<a href="#" class="myButton">Learn more</a>
</div>


</div>
</div>

<div class="jumbotron-2">
<div class="container">
<h1>What We Are</h1>
<p> A Paragraph</p> 
<div class="divbutton">
<a href="#" class="myButton">Learn more</a>
</div>


</div>
</div>

<div class="jumbotron-3">
<div class="container">
<h1>What We Are</h1>
<p> A Paragraph</p> 
<div class="divbutton">
<a href="#" class="myButton">Learn more</a>
</div>


</div>
</div>

Discovered a similar code snippet:

var slideShowDivs = ['.jumbrotron-1', '.jumbotron-2', '.jumbotron-3'];
var currentID = 0;
var slideShowTimeout = 1000;
$(document).ready(function() {
for (var i = 1; i < slideShowDivs.length; i++)              $(slideShowDivs[i]).hide();
setTimeout(slideShowChange, slideShowTimeout);
});
function slideShowChange() {
var nextID = currentID + 1;
if (nextID >= slideShowDivs.length) nextID = 0;
$(slideShowDivs[currentID]).stop(true).fadeOut(400);
$(slideShowDivs[nextID]).stop(true).fadeIn(400, function() {
    setTimeout(slideShowChange, slideShowTimeout);
});
currentID = nextID;
}​

However, it appears to be non-functional. Any suggestions?

Answer №1

Consider using jQuery each instead of a traditional for loop.

$('.jumbrotron-1,.jumbotron-2,.jumbotron-3').each(function() {
   $(this).hide();
   setTimeout(slideShowChange, slideShowTimeout);
  });

Check out the code on jsfiddle: http://jsfiddle.net/66Lz2xou/2/

Alternatively, you can use the following code:

$('div[class^="jumbrotron"]').each(function() {
   $(this).hide();
   setTimeout(slideShowChange, slideShowTimeout);
  });

Answer №2

Unfortunately, my commenting ability is restricted until I reach 50 reputation points. However, I wanted to build upon the idea presented by @ARUN BERTIL.

One approach could involve organizing the divs in an array:

let divArray = ['.jumbotron-1', '.jumbotron-2', '.jumbotron-3'];
jQuery.each(divArray, function(index, value){
/* Define actions for each div*/

    //example 
    $(value).css('background','blue');
})

Answer №3

If you're looking for the most effective method, consider utilizing this technique

  $( "div" ).each(function( index ) {
   //Your custom logic here
  }  });

Answer №4

Utilize class selectors for improved code organization.

$(".jumbotron-1 .jumbotron-2 .jumbotron-3").each(function( index ) {
   //Implement your custom logic here
  });

If necessary, extend the selector by adding a child container element using the > symbol like .jumbotran-1 > container
