The example in this article describes how JavaScript uses setTimeout to delay pop-up warning boxes. Share it with everyone for your reference. The details are as follows:
After the following code is executed, clicking the button will delay the pop-up of a warning box for 3 seconds, which mainly demonstrates the use of setTimeout
<!DOCTYPE html> <html> <body> <p> Click the button to wait 3 seconds, then alert "Hello". </p> <button onclick="myFunction()">Try it</button> <script> function myFunction() { setTimeout(function(){alert("Hello")},3000); } </script> </body> </html>
I hope this article will be helpful to everyone’s JavaScript programming design.
