I want to stop my javascript after x seconds, I saw that the function is setTimeout, I tried to add that to my code but no succes, is this the better way to do this? Thanks for your help !
<html>
<head>
<script type="text/javascript">
function blink(){
state = document.getElementsByTagName('img')[0].style.visibility;
if(state == 'hidden'){
newState = 'visible';
}else if(state == 'visible'){
newState = 'hidden';
}
document.getElementsByTagName('img')[0].style.visibility = newState;
}
setInterval('blink();', 300);
</script>

回答1:
Initialize your interval in a variable and clear it after X (here 2) seconds:
var interval = setInterval(blink, 300);
setTimeout(function() {
clearInterval(interval);
}, 2000);
回答2:
use like this:
var myvar;
function myStartFunction()
{
myvar=setInterval(function(){blink()},300);
}
function myStopFunction()
{
clearInterval(myvar);
}
