javascript - jquery ajax and after is duplicating the results -


i've got load more button, when clicked displays next 4 items, doing ajax call.

however, (for no apparent reason), content duplicated , returned twice, though when alert results, there's 1. happens when double click button.

any appreciated!

here's code:

/* load more */     $('.load-more').on('click',function(e){         e.preventdefault();         e.stoppropagation();          $('.pagination-holder').fadeout(250,function(){             $(this).remove();         });          var start = $(this).data('start'),             limit = $(this).data('limit'),             page = $(this).data('page'),             type = $(this).attr('href');          $.ajax({             url:'/index.php?route=news/news/getnext&start=4&limit=4&page=2',             method:'get',             data:{start:start,limit:limit,page:page},             datatype:'json'         }).done(function(data){              var html = '';              html +='<div class="row next" style="display:none">';             $.each(data.newss,function(i,news){                 html +='<div class="col-md-3 pt30">';                 html +='    <div class="image mb30"><a href="'+news.href+'"><img src="'+news.image+'" alt="'+news.title+'" class="responsive" /></a></div>';                 html +='    <div class="text">';                 html +='        <h3><a href="'+news.href+'">'+news.title+'</a></h3>';                 html +='        <p class="date mb5">'+news.date+'</p>';                 html +='        <p class="mb30">'+news.description+'</p>';                 html +='        <a href="'+news.href+'" class="btn mb30">read</a>';                 html +='    </div>';                 html +='</div>';                 if ((i+1) % 4 === 0) {                     html +='<div class="clear"></div>';                 }             });             html +='</div>';              //alert(html); /* when alert this, displays 1 row, should do, when don't alert this, can append duplicates */              $('#'+type+'-list').find('.row').after(html).ready(function(){                 $('.row.next').fadein(500).removeclass('next');             });          });     });
