I am currently building a website to host software. What I want is to add to the project pages is a slideshow of screenshots cycling, changing images about every 5 seconds. Is there any way to a script triggered at a time interval using just JavaScript? ..or will I have to resort to alternative methods for achieving my desired functionality. Thanks in advance for any help!
function doSomething() {
alert('This pops up every 5 seconds and is annoying!');
}
setInterval(doSomething, 5000); // Time in milliseconds
Pass it the function you want called repeatedly every n milliseconds. ( setTimeout
, by the way, will call a function with a timeout.)
If you ever want to stop the timer, hold onto setInterval
's return value and pass it to clearInterval
.
You want the setInterval
function.
setInterval(function() {
// This will be executed every 5 seconds
}, 5000); // 5000 milliseconds
Basic reference: http://www.w3schools.com/jsref/met_win_setinterval.asp (please ignore the reference to the "lang" parameter)
More indepth reference: https://developer.mozilla.org/en-US/docs/Web/API/window.setInterval
You can use window.setInterval
Sample usage:
window.setInterval(function () {
console.log("foo");
}, 3000);
It Changes the date time in a div and time changes frequently after 1 sec.
setInterval(function(){
var date=new Date();
$('.class').html(date);
},1000);
<script>
var intervalVariable=setInterval(function(){
//Your operation goes Here
},1000); // executes every 1000 milliseconds(i.e 1 sec)
function stopTimer()
{
clearInterval(intervalVariable);
}
</script>
