Note that we will be using onclick event of period button for this. We will call it as a reminder script and we will get one alert box based on the period button we clicked.

The setInterval function is similar to setTimeout in that it also allows you to execute code. Here is the syntax for the setTimeout() method. The next timer function we are going to look at is setInterval. Display the clock on the page, and stop the clock when it reaches zero. We set off an interval timer, specifying a delay of 1 ms, and for the first 100. Output the clock data as a reusable object. We will try one example where we will have four period buttons and each button will set a different time for another function to execute and display a alert button. setTimeout() is a method that will execute a piece of code after the timer has finished running. How JavaScript handles threading An examination of timer execution. For example if msec is set 5000 then the expression will be executed after 5 seconds or 5000 milliseconds. You can see by using setTimeout function we can execute any function or object after a set of time. Msec is the duration of time in milliseconds after which the expression will be executed. The following are the two functions provided by JavaScript for this purpose: 1. Mytime = setTimeout(expression, msec) mytime is the identifier used to identify the current timeout function.Įxpression is the statement that is to be executed after the specified time has ticked off. The function setTimeout() in function is used and here is its general syntax.
