不必每次循环都重复脚本

Question

I have the following script that happens within a loop. How would I make it so I only have to place it once at the bottom of a page and not have the classes hard coded in? The script occurs for each <li> which seems very clunky.

Here's the script

  <script>
    $(".<?php echo strtolower(get_field('code'));?>_btn").click(function(){
        $("#<?php echo strtolower(get_field('code'));?>").on('show', function () {

            $('iframe.fohl-mobile').attr("src","http://www.psfk.com/home#<?php echo get_field('code');?>");

        });
    });
  </script>

Here's the whole piece that repeats in the loop

 <li>
    <a data-toggle="modal" role="button" class="<?php echo strtolower(get_field('code'));?>_btn" href="#<?php echo strtolower(get_field('code'));?>">&nbsp;</a>

    <img class="lazy" alt="<?php the_title();?>" src="<?php echo site_url('wp-content/fohl/holder.png');?>" data-original="<?php echo site_url('/wp-content/fohl/products/').strtolower(get_field('code'));?>.png" />
    <noscript><img src="<?php echo site_url('/wp-content/fohl/products/').strtolower(get_field('code'));?>.png” alt="<?php the_title();?>"/></noscript>

    <div class="title"><?php the_title();?>

    <div id="<?php echo strtolower(get_field('code'));?>" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <iframe class="fohl-mobile" height="500" width="330" frameborder="0"  src=""></iframe>
      <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
      </div>
    </div>
    <script>
        $(".<?php echo strtolower(get_field('code'));?>_btn").click(function(){
            $("#<?php echo strtolower(get_field('code'));?>").on('show', function () {

                $('iframe.fohl-mobile').attr("src","<?php echo site_url('/home#'.get_field('code'));?>");

            });
        });
    </script>
 </li>

Got it. I added an id to the li and went from there...thanks for the help everyone.

 <ul class="products">  
        <?php foreach($products as $post) : setup_postdata($post);?>  
        <li>
            <a data-toggle="modal" role="button" class="this_btn" href="#<?php echo get_field('code');?>">&nbsp;</a>

            <img class="lazy" alt="<?php the_title();?>" src="<?php echo site_url('/wp-content/fohl/holder.png');?>" data-original="<?php echo site_url('/wp-content/fohl/products/').strtolower(get_field('code'));?>.png" />
            <noscript><img src="<?php echo site_url('/wp-content/fohl/products/').strtolower(get_field('code'));?>.png" alt="<?php the_title();?>"/></noscript>

            <p class="title"><?php the_title();?></p>

            <div id="<?php echo get_field('code');?>" class="modal hide fade" class="goat" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
                <iframe class="fohl-mobile" height="500" width="330" frameborder="0"  src=""></iframe>
              <div class="modal-footer">
                <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
              </div>
            </div>
        </li>
    <?php endforeach;?>
    <script>
        $(".this_btn").click(function(){
            var id = $(this).parent().find('div').attr('id');

            $('.modal').on('show', function() {     
                $('.modal iframe.fohl-mobile').attr("src","http://www.website.com/home#"+id);
            });
        });
    </script>
 </ul>
