So now you know how to pass arguments to the setTimeout() function. Output: Of the above code will be an alert message displaying “Javascript is the best.” after 3 seconds. We can use the third argument to specify the name to be displayed in the message and passed to the function and create the message accordingly. Now you will use setTimeOut() function with more than two arguments to it. In this case, you will use setTimeOut() function as the message is to be displayed only once after some time and not repetitively. For example, You want to display a message after 3 seconds of clicking the submit button and the message should display the name passed to that function. Now suppose in a real-time situation, there’s comes a necessity to pass a parameter to the function which is being called. In the middle of countdown if you press “Stop It” button then the timer will stop and message displayed will also stop displaying the message which was getting seen at that particular instance when you pressed the button and will not be modified further. Var progressBarId = setInterval(displayProgress ,1000) ĭocument.getElementById("progressBar").innerHTML = waitingCount + " Seconds Left!" ĭocument.getElementById("progressBar").innerHTML = "Yes! You have done it!" ĬlearInterval(progressBarId) //Display the final message and clear the timerĮxplanation: The message will show the countdown and will display “Yes! You have done it!” after ten seconds. How can we implement it? Here’s where we can make the use of setInterval() function. Now suppose you want to update the message saying “10 Seconds Left!”,“9 Seconds Left!”,… and so on and display “Yes! You have done it!”. Output: The output of the above program will be as follows. You can use it by calling it with the id returned from setInterval() function.As soon as you will click the stop button it will stop displaying the updated time and will display the time when you clicked the button. Var currentTime= currentDate.toLocaleTimeString() ĭocument.getElementById("displayTime").innerHTML = currentTime Įxplanation: clearInterval() function is used to stop the event from occurring. 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. Suppose you want to display a digital clock and stop it when you click “Stop” button. 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. Here’s how your code will look somewhat like this-Ĭlick "Purpose"to know what brings you here.Īlert('Hi! You are here to learn timers in Javascript.') Ĭode: After 5 seconds of clicking the button output seen will be as shownĮxplanation: clearTimeout() function is used to stop the event from occuring. In this case, you can write a function alerting the message and use setTimeout function to call it after 5 seconds on click of the button named “Purpose”. For example, if you want to print a message saying “Hi! You are here to learn timers in JavaScript.” after 5 seconds of clicking the button named “Purpose”. Zero the idle timer on mouse movement.SetTimeout() function allows you to execute a specific functionality after some time period. Var idleInterval = setInterval(timerIncrement, 60000) // 1 minute Increment the idle time counter every minute. Here is a simple script using jQuery that handles mousemove and keypress events.
