CSS Question

how to put a link on the photo after the photo opens?

I hope you don't mind helping me with this code.
I'm using bootstrap and I have this html:

<div class="gallery">
<div class="container">
<div class="row">
<div class="col-xs-3 gallery-item">
<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery">
<img src="images/port1.jpg" class="img-responsive img-gallery" alt="Projekti i pare">
</a>
</div> <!-- /.col -->

<div class="col-xs-3 gallery-item">
<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery">
<img src="images/port2.jpg" class="img-responsive img-gallery" alt="Projekti i dyte">
</a>
</div> <!-- /.col -->

<div class="col-xs-3 gallery-item">
<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery">
<img src="images/port3.jpg" class="img-responsive img-gallery" alt="Projekti i trete">
</a>
</div> <!-- /.col -->

<div class="col-xs-3 gallery-item">
<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery">
<img src="images/port4.jpg" class="img-responsive img-gallery" alt="Projekti i katert">
</a>
</div> <!-- /.col -->
<div class="col-xs-3 gallery-item">
<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery">
<img src="images/port4.jpg" class="img-responsive img-gallery" alt="Projekti i peste">
</a>
</div> <!-- /.col -->
<div class="col-xs-3 gallery-item">
<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery">
<img src="images/port4.jpg" class="img-responsive img-gallery" alt="Projekti i gjashte">
</a>
</div> <!-- /.col -->
<div class="col-xs-3 gallery-item">
<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery">
<img src="images/port4.jpg" class="img-responsive img-gallery" alt="Projekti i shtate">
</a>
</div> <!-- /.col -->
</div> <!--/.row -->
</div> <!-- /.container -->
</div> <!-- /.gallery -->

<div class="modal fade" id="modalGallery" tabindex="-1" role="dialog" aria-labelledby="modalGalleryLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="modalGalleryLabel">Gallery</h4>
</div> <!-- /.modal-header -->

<div class="modal-body">
<div id="carouselGallery" class="carousel slide" data-ride="carousel" data-interval="false">
<div class="carousel-inner">
</div> <!-- /.carousel-inner -->
</div> <!-- /.carousel -->
</div> <!-- /.modal-body -->

<div class="modal-footer">
<ul class="pagination">
</ul>
</div> <!-- /.modal-footer -->
</div> <!-- /.modal-content -->
</div> <!-- /.modal-dialog -->
</div> <!-- /.modal -->


This is my css:

.gallery{
margin-top: 100px;
}
.gallery-item{
margin-bottom: 30px;
}
.modal-footer{
text-align: center;
}
.pagination{
margin: 0;
}


And my Javacsript

$(document).ready(function(){
$('.link-gallery').click(function(){
var galleryId = $(this).attr('data-target');
var currentLinkIndex = $(this).index('a[data-target="'+ galleryId +'"]');

createGallery(galleryId, currentLinkIndex);
createPagination(galleryId, currentLinkIndex);

$(galleryId).on('hidden.bs.modal', function (){
destroyGallry(galleryId);
destroyPagination(galleryId);
});

$(galleryId +' .carousel').on('slid.bs.carousel', function (){
var currentSlide = $(galleryId +' .carousel .item.active');
var currentSlideIndex = currentSlide.index(galleryId +' .carousel .item');

setTitle(galleryId, currentSlideIndex);
setPagination(++currentSlideIndex, true);
})
});

function createGallery(galleryId, currentSlideIndex){
var galleryBox = $(galleryId + ' .carousel-inner');

$('a[data-target="'+ galleryId +'"]').each(function(){
var img = $(this).html();
var galleryItem = $('<div class="item">'+ img +'</div>');

galleryItem.appendTo(galleryBox);
});

galleryBox.children('.item').eq(currentSlideIndex).addClass('active');
setTitle(galleryId, currentSlideIndex);
}

function destroyGallry(galleryId){
$(galleryId + ' .carousel-inner').html("");
}

function createPagination(galleryId, currentSlideIndex){
var pagination = $(galleryId + ' .pagination');
var carouselId = $(galleryId).find('.carousel').attr('id');
var prevLink = $('<li><a href="#'+ carouselId +'" data-slide="prev">«</a></li>');
var nextLink = $('<li><a href="#'+ carouselId +'" data-slide="next">»</a></li>');

prevLink.appendTo(pagination);
nextLink.appendTo(pagination);

$('a[data-target="'+ galleryId +'"]').each(function(){
var linkIndex = $(this).index('a[data-target="'+ galleryId +'"]');
var paginationLink = $('<li><a data-target="#carouselGallery" data-slide-to="'+ linkIndex +'">'+ (linkIndex+1) +'</a></li>');

paginationLink.insertBefore('.pagination li:last-child');
});

setPagination(++currentSlideIndex);
}

function setPagination(currentSlideIndex, reset = false){
if (reset){
$('.pagination li').removeClass('active');
}

$('.pagination li').eq(currentSlideIndex).addClass('active');
}

function destroyPagination(galleryId){
$(galleryId + ' .pagination').html("");
}

function setTitle(galleryId, currentSlideIndex){
var imgAlt = $(galleryId + ' .item').eq(currentSlideIndex).find('img').attr('alt');

$('.modal-title').text(imgAlt);
}
});


I want to add an href link in the photo, when the photo gets bigger.What should I do?

Answer

Just add <a href=""></a>, while you are assigning the galleryItem.

Like:

var galleryItem = $('<div class="item"><a href="your-link">'+ img +'</a></div>');

To add different-different links to each <a> use an extra attribute 'data-link' in your link,

<a href="#galleryImg1" class="link-gallery" data-toggle="modal" data-target="#modalGallery" data-link="your-link-1">

And in JS, create a variable and get that link via .attr() function & append this into your link like,

// Get the link from data attribute 'data-link'
var imgLink = $(this).attr('data-link');

// Append the link into the 'galleryItem'
var galleryItem = $('<div class="item"><a href="' + imgLink + '">'+ img +'</a></div>');

Have a look at the snippet below:

$(document).ready(function(){
			     $('.link-gallery').click(function(){
			    var galleryId = $(this).attr('data-target');
			    var currentLinkIndex = $(this).index('a[data-target="'+ galleryId +'"]');
			    var imgLink = $(this).attr('data-link');

			    createGallery(galleryId, currentLinkIndex, imgLink);
			    createPagination(galleryId, currentLinkIndex);

			    $(galleryId).on('hidden.bs.modal', function (){
			        destroyGallry(galleryId);
			        destroyPagination(galleryId);
			    });

			    $(galleryId +' .carousel').on('slid.bs.carousel', function (){
			        var currentSlide = $(galleryId +' .carousel .item.active');
			        var currentSlideIndex = currentSlide.index(galleryId +' .carousel .item');

			        setTitle(galleryId, currentSlideIndex);
			        setPagination(++currentSlideIndex, true);
			    })
			});

			function createGallery(galleryId, currentSlideIndex, imgLink){
			    var galleryBox = $(galleryId + ' .carousel-inner');

			    $('a[data-target="'+ galleryId +'"]').each(function(){
			        var img = $(this).html();
			        var galleryItem = $('<div class="item"><a href="' + imgLink + '">'+ img +'</a></div>');

			        galleryItem.appendTo(galleryBox);
			    });

			    galleryBox.children('.item').eq(currentSlideIndex).addClass('active');
			    setTitle(galleryId, currentSlideIndex);
			}

			function destroyGallry(galleryId){
			    $(galleryId + ' .carousel-inner').html("");
			}

			function createPagination(galleryId, currentSlideIndex){
			    var pagination = $(galleryId + ' .pagination');
			    var carouselId = $(galleryId).find('.carousel').attr('id');
			    var prevLink = $('<li><a href="#'+ carouselId +'" data-slide="prev">«</a></li>');
			    var nextLink = $('<li><a href="#'+ carouselId +'" data-slide="next">»</a></li>');

			    prevLink.appendTo(pagination);
			    nextLink.appendTo(pagination);

			    $('a[data-target="'+ galleryId +'"]').each(function(){
			        var linkIndex = $(this).index('a[data-target="'+ galleryId +'"]');
			        var paginationLink = $('<li><a data-target="#carouselGallery" data-slide-to="'+ linkIndex +'">'+ (linkIndex+1) +'</a></li>');

			        paginationLink.insertBefore('.pagination li:last-child');
			    });

			    setPagination(++currentSlideIndex);
			}

			function setPagination(currentSlideIndex, reset = false){
			    if (reset){
			        $('.pagination li').removeClass('active');
			    }

			    $('.pagination li').eq(currentSlideIndex).addClass('active');
			}

			function destroyPagination(galleryId){
			    $(galleryId + ' .pagination').html("");
			}

			function setTitle(galleryId, currentSlideIndex){
			    var imgAlt = $(galleryId + ' .item').eq(currentSlideIndex).find('img').attr('alt');

			    $('.modal-title').text(imgAlt);
			}
			      });
