From: FAQ server on 23 Apr 2010 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 ` getSnork ` may exceed the second parameter to ` setTimeout ` and ` setInterval ` due to implementation differences among browsers. To call the function ` getSnork `, approximately 10 seconds after the function ` getMoomin() ` completes, you would do this: getMoomin(); setTimeout(getSnork, 10000); Script execution is not stopped, and adding ` getSnufkin() ` after the ` setTimeout ` line would immediately execute the function ` getSnufkin ` before ` getSnork `. Achieving delays through running a loop of some sort for a pre-defined period is a bad strategy, as that will inhibit whatever was supposed to be happening during the delay, including blocking user interation. Other (less event driven) hosts have different wait functions, such as ` WScript.Sleep() ` in the Windows Script Host. http://msdn.microsoft.com/en-us/library/ms536753%28VS.85%29.aspx http://docs.sun.com/source/816-6408-10/window.htm#1203758 http://en.wikipedia.org/wiki/Event-driven_programming http://jibbering.com/faq/faq_notes/misc.html#mtSetTI The complete comp.lang.javascript FAQ is at http://jibbering.com/faq/ -- The sendings of these daily posts are proficiently hosted by http://www.pair.com. |
