问题
In my situation, I have to set the month to last month as default.
The default month for the datepicker is current month. But I want it to be last month or other month as default showing. How can I make it?
Such as: "2010-09" as the default.
Thank you very much!

You can use the defaultDate option when creating the datepicker:
$('#date').datepicker({
defaultDate: '-2m'
});
By passing in a string like this we can set the default date to another one relative to the current date. Alternatively, the option also accepts a Date object:
defaultDate: new Date(2010, 8, 1)
or a string in the same format as the format currently defined:
defaultDate: '1/9/2010'
All of the above will give you a default date in September. The month in the Date constructor starts from zero, so 8 will give you September.

I think you actually want this when you're only showing 1 month at a time.
$( ".selector" ).datepicker({ showCurrentAtPos: 1 });
If you use defaultDate it will highlight that particular day, this method just shows the previous month with nothing selected.

Try this
$( ".selector" ).datepicker({ defaultDate: +7 });
Specify either an actual date via a Date object or as a string in the current dateFormat, or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.
