<a href="#" onclick="Session.set('videoNum',{{index}})">     
     <li class="{{#if {{index}}==Session.get('videoNum') }}    // 'index' is changing on each loop,how to judge if index //equal to 'videoNum' ?

Yes handlebar-helpers works but perhaps your own helper may be simpler, something like

<li class="{{#if videoNumEquals index  }}    // 'index' is changing
...
videoNumEquals: function(index) {
  return Session.get('videoNum') == index;
}

Me, I use a general comparison helper:

Template.registerHelper 'equals', (a,b) ->
	if a==b then true

and

{{#if equals helper1 helper2}}
   <render_something>
{{/if}
