javascript - Open different image in lightbox -


i have image light-box in bootstrap , want achieve when user clicks on image, image pops different.

so have thumb icons, , when user clicks 1 of them full image displayed. code like:

<a href="full_image_url" ..> <img src="thumb_img_url" ...></a>

i tried edit <a href="#" ..> location of other image didn't work..

var $lightbox = $('#lightbox');    $('[data-target="#lightbox"]').on('click', function(event) {    var $img = $(this).find('img'),      src = $img.attr('src'),      alt = $img.attr('alt'),      css = {        'maxwidth': $(window).width() - 100,        'maxheight': $(window).height() - 100      };      $lightbox.find('.close').addclass('hidden');    $lightbox.find('img').attr('src', src);    $lightbox.find('img').attr('alt', alt);    $lightbox.find('img').css(css);  });    $lightbox.on('shown.bs.modal', function(e) {    var $img = $lightbox.find('img');      $lightbox.find('.modal-dialog').css({      'width': $img.width()    });    $lightbox.find('.close').removeclass('hidden');  });
body {    padding: 30px 0px;  }    #lightbox .modal-content {    display: inline-block;    text-align: center;  }    #lightbox .close {    opacity: 1;    color: rgb(255, 255, 255);    background-color: rgb(25, 25, 25);    padding: 5px 8px;    border-radius: 30px;    border: 2px solid rgb(255, 255, 255);    position: absolute;    top: -15px;    right: -55px;    z-index: 1032;  }

you have attached event handler click event of <a data-target="#lightbox'>. can find parent div , next sibling div , image inside it. incase of last div can first sibling. this:

var $lightbox = $('#lightbox');    $('[data-target="#lightbox"]').on('click', function(event) {      var imagediv = $(this).parent().is(':last-child') ? $(this).parent().siblings().first() : $(this).parent().next();      var $img = $(imagediv).find('img'),      src = $img.attr('src'),      alt = $img.attr('alt'),      css = {        'maxwidth': $(window).width() - 100 ,        'maxheight': $(window).height() - 100      };      $lightbox.find('.close').addclass('hidden');    $lightbox.find('img').attr('src', src);    $lightbox.find('img').attr('alt', alt);    });    $lightbox.on('shown.bs.modal', function(e) {    var $img = $lightbox.find('img');      $lightbox.find('.modal-dialog').css({      'width': $img.width()    });    $lightbox.find('.close').removeclass('hidden');  });
body {    padding: 30px 0px;  }    #lightbox .modal-content {    display: inline-block;    text-align: center;  }    #lightbox .close {    opacity: 1;    color: rgb(255, 255, 255);    background-color: rgb(25, 25, 25);    padding: 5px 8px;    border-radius: 30px;    border: 2px solid rgb(255, 255, 255);    position: absolute;    top: -15px;    right: -55px;    z-index: 1032;  }
