Oh , i wanted to update my post, seems like i accidently deleted the original one , sorry for that , and thanks for answers

hi.

Whats the diffrence between setTimeout and setInterval?

I mean , when i want to make slideshow setTimeout works but Setinverval doesnt , but both of them should work for that.

Just for info , while loop doesnt make what for in term of chaning speed right?

for example

function swapImage() { var i=0;document.slide.src = path[i]; while(i < path.length -1 ){ i++;} ;if(i>path.length) {i = 0;} ; setTimeout("swapImage()",3000); } window.onload=swapImage; 

dont work >{

Thank you very much for good explanation sir!

I know that it works if i use if(), but why it does now work with for{} aswell?

//thanks for answer

Hello ,

<img id="matej" src="http://thegraphicsfairy.com/wp-content/uploads/blogger/-72LEqJJmnH0/TtoypcjmR8I/AAAAAAAAPjA/3AbGm3448JU/s1600/alarm%2Bclock%2Bsmall%2Bvintage%2Bimage%2Bgraphicsfairy2.jpg" width=100px; height="50px"> <script>var lol=new Array();lol[0]="https://guardian-registration.s3.amazonaws.com/networks/network/illustration/Illustration-small_business.png"lol[1]="http://peach.blender.org/wp-content/uploads/poster_rodents_small.jpg";lol[2]="http://upload.wikimedia.org/wikipedia/en/8/85/Small_soldiers_movie_poster.jpg";function torko(){ for(i=0;i<lol.length;i++){var x=document.getElementById("matej");x.src=lol[i];}setTimeout("torko()",3000);  } window.onload=torko;</script> 

why isnt my for loop working? (it does not slide the image) ; also if i use

if(i<lol.length-1){i++}else{i=0}

it works , can someone explain why please?

Got it , thanks

<div id="ahoj"></div><div id="lol"></div><div id="cai"></div><button id="matek"> cau </button>   function sg(){x=document.getElementById("cai");g=x.style.display;if(g=="none"){g=="block"}else{g=="none"};} window.onload=zmena;function zmena(){    document.getElementById("matek").onclick=sg;}

i have set #cai{display:none;}

Can you tell me whats wrong with my script and why it isnt workign? (its writting only error nothing more)// on the different IDE it writtes"none is not defined

Thank you very much sir (it wasnt exactly what i wanted , but thank to you i figured out how to do it , so its even better )
