On this page I have the MP3-jPlayer WordPress plugin with the Text Skin, slightly modified.

I have deleted the volume bar from the plugin’s html/php structure. I have also added a “seekbar”:

 

  
<div class="seekbar-wrapper">
  
 <div class="seekbar-container">
  
 <div class="seekbar" value="0" max="1"></div>
  
 </div>
  
</div>
 

I have modified the plugin’s mp3-jplayer-2.7.js file in order to show, for every track (mp3 files), the timeline. After line 403 (jQuery(this.eID.indiM + j).empty().append('<span class="Smp3-tint tintmarg"></span> ' + this.Tformat(pt));) I have added:

 

  
var sbContainerWidth = $('.seekbar-container').width();
  
var progValue = pt / tt * 100;
  
var progPercentage = progValue + '%'; 
  
$('#mp3jWrap' + '_' + this.tID).closest('li').find('.seekbar').width(progPercentage);
 

The result of this is the presence of a progress bar that was missing before.

I have tried to make the seekbar react to a click event and update the track’s "timer:

 

  
var sbContainerWidth = $('.seekbar-container').width();
  
 function skip(ev) {
  
 pt = ev.pageX - $('.seekbar-container').offsetLeft; 
  
}
 

But unfortunately it does not react to the clicking (and the timeline does not update).

Why? Where is the mistake?
