Today, you are experiencing a problem with a timed operation in your project. JavaScript provides two methods for timed operations: The code is as follows Copy Code 1, Timeid = settimeout ("function ();", delaytime); Timeid is the ID of the timer (used later), The Delaytime unit is 1 per thousand seconds, millisecond. The code is as follows Copy Code 2, Timeid = SetInterval ("functio

After the dialog box is closed, the time of

In fact, why don't I think about it
