javascript - Show next image in Array onClick -


i working on setting images can clicked through on screen arrows. have images showing via loop , array. have been able set when hover on smallimage preview main image change image. aka can hover on them see larger version.

my array within mongo model: listings.currentimages

my current code below works small image take on featured image when hovered on. how change code work on screen left/right arrows? 

<% var imgsrc = awspath + listings.currentimages[0] %> <img  id='mainpicture' class="image-resposive" src=<%=imgsrc%>> <div id='allimages'>     <% for(var = 0; < listings.currentimages.length; i++ ) { %>         <div class='smallerimages'>             <% var imgsrc = awspath + listings.currentimages[i] %>             <img class="small" src="<%= imgsrc %>">         </div>     <% } %> </div>

hover feature: 

$('.small').hover(function() {     $('.small').removeclass('selectedimage')     var src = $(this).attr('src');     $(this).addclass('selectedimage')     $('#mainpicture').attr('src', src); });

assuming have 2 icons (next/prev) can define 2 following event handlers in order move right or left:

$('#nextarrow').on('click', function(e) {     var anchestor = $('.small.selectedimage').closest('.smallerimages');     var nextimg = $('#allimages .smallerimages:first .small');     if (anchestor.next().length != 0) {        nextimg = anchestor.next().find('.small');     }     $('.small').removeclass('selectedimage');     var src = nextimg.attr('src');     nextimg.addclass('selectedimage');     $('#mainpicture').attr('src', src); })   $('#prevtarrow').on('click', function(e) {     var anchestor = $('.small.selectedimage').closest('.smallerimages');     var nextimg = $('#allimages .smallerimages:last .small');     if (anchestor.prev().length != 0) {         nextimg = anchestor.prev().find('.small');     }     $('.small').removeclass('selectedimage');     var src = nextimg.attr('src');     nextimg.addclass('selectedimage');     $('#mainpicture').attr('src', src); })
