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 ?
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.
