JavaScript call function after delay
Its very easy to call function after certain time delay or interval. JavaScript has setTimeout() function which call another function after certain delay or interval.
Syntax of setTimeout() method:
setTimeout(function_name, delay_in_miliseconds);

{
document.getElementById(“result”).innerHTML=”Test method is called”;
}
setTimeout(test, 5000); // this will call test function after 5 seconds
JavaScript call function every interval
In JavaScript we can call a particular function repeatedly after certain time delay. JavaScript has setInterval() method which calls another function repeatedly after certain duration.
Syntax of setInterval() method:
setInterval(function_name, delay_in_miliseconds);
Example of setInterval():
function test()
{
document.getElementById(“result”).innerHTML=”Test method is called”;
}
setInterval(test, 3000); // this will call test function every 3 seconds
JavaScript call function every 5 seconds
Example of JavaScript call function every 5 seconds is given below
function test()
{
document.getElementById(“result”).innerHTML=”Test method is called”;
}
setInterval(test, 5000); // this will call test function every 5 seconds
