I need to enable message notifications on a webpage,
Example,
User receives a message and I notify him that he has a new message but does not refresh the page.
How can I make a function that runs every two or three seconds an ajax to check if a new message is available?
use the setInterval function, documentation here
for example to perform its function every 3 seconds
<script type="text/javascript">
<!--
window.onload = function() {
function funcaoAjax(){
console.log('Executando');
}
var intervalo = setInterval(funcaoAjax,3000);
}
//-->
</script>To stop execution, use the clearInterval method. documentation here
clearInterval(intervalo );
