Here’s how you can write the code-Ĭlick "Stop" to stop the displayed time over here. Then you can use the setInterval method to call the getTime function repetitively after 1 second so that the time displayed will be updated.

When you want to execute certain functionality repetitively after particular time period then you can use setInterval function to do so. Where argument1 stands for reference of the function to be executed, argument2 for the time period in milliseconds after which you want to repetitively execute the function and argument3 and so on exists as an optional parameter you want to pass to function reference of argument1.
tInterval(argument1,argument2,argument3,….) For example in the above case if id returned of the timer is stored in variable name timeouteId and you call the clearTimeout(timeouteId) before 5 seconds then the message haven’t be displayed. You can use it by calling it with the id returned from setTimeout() function. Click "Purpose"to know what brings you here.Īlert('Hi! You are here to learn timers in Javascript.')
