From: FAQ server on 3 Jul 2008 19:00 ----------------------------------------------------------------------- FAQ Topic - How do I make a 10 second delay? ----------------------------------------------------------------------- There is no built-in way to pause execution in javascript such as a sleep function, but hosts usually provide a method of some form. Web browsers are designed for event driven programming and only provide the ` setTimeout ` and ` setInterval ` functions to facilitate timed delays. The delay before calling Snork may exceed the second parameter to ` setTimeout ` and ` setInterval ` due to implementation differences among browsers. To call the function ` Snork() `, approx 10 seconds after the function ` Moomin() `, you would do this: Moomin() setTimeout('Snork()',10000) Script execution is not stopped, and adding ` Snufkin() ` after the setTimeout line would immediately execute the function ` Snufkin() ` before ` Snork() ` Achieving delays through running a loop of some sort for a pre-defined period is a bad strategy, as that will tend to put CPU use up to 100% and inhibit whatever was supposed to be happening during the delay. Other (less event driven) hosts have different wait functions, such as ` WScript.Sleep() ` in the Windows Script Host. http://msdn2.microsoft.com/en-us/library/ms536753.aspx http://docs.sun.com/source/816-6408-10/window.htm#1203758 http://en.wikipedia.org/wiki/Event-driven_programming -- Postings such as this are automatically sent once a day.
