and here html.

<div id="dislike_box">                                     <?php                                         $likeimage='';                                         $dlikeimage='';                                         if($this->basic->get_video_liked_or_not($vid->id)==1){                                             $likeimage ='<a href="#" class="likeedthis"><img src="'.base_url().'images/like.jpg" /></a>';                                         }else{                                             $likeimage ='<a href="'.$vid->id.'" class="likethis"><img src="'.base_url().'images/like_over.jpg" /></a>';                                         }                                         if($this->basic->get_video_dliked_or_not($vid->id)==1){                                             $dlikeimage='<a href="#" class="dlikedthis"><img src="'.base_url().'images/dis_lik.jpg" /></a>';                                         }else{                                             $dlikeimage='<a href="'.$vid->id.'" class="dlikethis"><img src="'.base_url().'images/dis_lik_over.jpg" /></a>';                                         }                                     ?>                                     <?php echo $dlikeimage; ?>                                     </div>                                     <div id="like_box">                                     <?php echo $likeimage; ?>                                     </div>

the problem when click button first time image changing 'liked' image, if click dislike button page refreshing instead of disliking video. after refreshing clicked dislike again. working. same happens button. can tell me why happen?

use event delegation as adding elements dynamically

$("#dislike_box").on('click',".dlikethis",function(event){..}); $("#like_box").on('click',".likethis",function(event){..});
