Yes you can, if you use a proper event handler, all you have to do is trigger it. — adeneo

You can write a function call in window.load event to get a function executed on page load — thiru

Either use JQuery's $(document).ready()

or without JQuery, something like this would work in about 98% of browsers:

document.addEventListener("DOMContentLoaded", function(event) { 
  //do work
});

There's a great answer here with a bit more detail on the subject https://stackoverflow.com/a/800010/8055700

can i add time interval this function? ex. after the 3 second started . My English not perfect sorry for this =)

Sure you can. Check out the setTimeout() and setInterval() functions. Really good tutorial here: w3schools.com/js/js_timing.asp

t.niese Over a year ago

You should avoid to link to w3schools, even after years they still suffer from inaccuracies and lack important informations. E.g. they write [...]The setTimeout() and setInterval() are both methods of the HTML DOM Window object.[...] which is not essential wrong, but they are both utility functions (not methods) exposed by the window object, or nowadays are part of the window or webworker global scope.
