title: how should i call a javascript function into a kohana view?
body: <p>i am having a simple kohana view, and a javascript that makes a countdown of 30 minutes.
  I hava put the javascript file into a directory /media m and its name is countdown.js
   . My problem is: how can i call that javascript? Form the view? Or from the controller to be displayed in the view? and how exactly may i address in a controller or a view that js function or functions?</p>
  
  <p>thank you</p>
  
  <p>the countdown js: </p>
  
  <p>var javascript_countdown = function () {
      var time_left = 10; //number of seconds for countdown
      var output_element_id = 'javascript_countdown_time';
      var keep_counting = 1;
      var no_time_left_message = 'No time left for JavaScript countdown!';</p>
  
  <pre><code>function countdown() {
      if(time_left &lt; 2) {
          keep_counting = 0;
      }
  
      time_left = time_left - 1;
  }
  
  function add_leading_zero(n) {
      if(n.toString().length &lt; 2) {
          return '0' + n;
      } else {
          return n;
      }
  }
  
  function format_output() {
      var hours, minutes, seconds;
      seconds = time_left % 60;
      minutes = Math.floor(time_left / 60) % 60;
      hours = Math.floor(time_left / 3600);
  
      seconds = add_leading_zero( seconds );
      minutes = add_leading_zero( minutes );
      hours = add_leading_zero( hours );
  
      return hours + ':' + minutes + ':' + seconds;
  }
  
  function show_time_left() {
      document.getElementById(output_element_id).innerHTML = format_output();//time_left;
  }
  
  function no_time_left() {
      document.getElementById(output_element_id).innerHTML = no_time_left_message;
  }
  
  return {
      count: function () {
          countdown();
