jquery - javascript zoom default image after change image src value -


there's problem javascript here. first, if click image zoom image. problem when image change different 1 , click, still zoom first image, not new one.

my html (container show image , zoom it)

<div class="col-md-8">      <span  id='ex3' class="zoom">        <img class="img-responsive" id="myimage" width='750' height='550' src="<?php echo "./image/product/p1/". $row['item_image']. ".jpg"; ?>">      </span> </div> 

my html (next image want click , zoom)

<div class="col-sm-3 col-xs-6">    <a href="#">       <img class="img-responsive portfolio-item subimage"  onclick="changeimage1(); <?php $show1="./image/product/p1/". $row['item_image']. ".jpg"; ?>" src="<?php echo "./image/product/p1/". $row['item_image']. ".jpg"; ?>" alt="">    </a> </div> 

my javascript in body tag

function changeimage1() {     var image = document.getelementbyid('myimage');     var submage = document.getelementsbyclassname('subimage')[1].src;      image.src= submage;         } 

my javascript in head tag (zoom function)

 jquery(document).ready(function($){      $('#ex3').zoom({ on:'click' });           }); 

how fix it, ideas? thanks.

jquery(document).ready(function($){         $('img').zoom({ on:'click' });              });
