common methods for Date objects:Year: getFullYear ();    Month: GetMonth () + 1; Note: the value.    The method returns an integer from 0 to 11, so according to China's custom, it should be followed + 1st: GetDate ();    Time: GetHours (); Points: getminutes ();
Seconds: getseconds ();
....................
the way JavaScript calls functions at timed intervals:The timing Method 1:setinterval ("The function to invoke or the code string to execute", periodically executes or calls the time interval between code, in milliseconds ");
Timing Method 2:
SetTimeout ("The JavaScript code string to execute after the function to invoke", "the number of milliseconds to wait before executing the code.") ");


InnerHTMLProperty sets or returns the HTML between the start and end tags of a table row.
For example: Locate the Span object
var spanobj = getElementById ("CurrentTime");
Set the contents of a span tag bodyspanobj.innerhtml = Timeinfo.fontcolor ("Red"). FontSize ("5px"); The InnerHTML property sets or returns the HTML between the start and end tags of a table row. Note:
1. The first parameter of the timing method above should be enclosed in quotation marks (including functions), and the second argument can be enclosed in parentheses or not.
2.setTimeout () executes code only once. If you want to call more than once, use SetInterval () or let code itself call SetTimeout () again.
