Ajax Refresh Problem

[2mk_atspace]

I build online presentation with Ajax. When preseneter change the slide, the participant slide also change, i use

setTimeout('checkChange();',2000);

The problem is how if i only want participant slide change only when presenter change the slide. If i use timer slide will refresh every 2 second.

Anyone can help me ?

Make an HTML button, onclick"changeSlide()" ?

[2mk_atspace]

I already made that.

I will give more explanation

Presenter press change slide button -> then presenter slide and participant slide change.

Note : Presenter and participant in different computer.

Why not set it up so $i = the number slide each person is on.

Your onclick JS function will just have $i++ in it; each time the button is clicked increment $i up one more.
