How to use javascript to obtain the date of the previous month before the current date

<Script>
Var myDate = new Date ();
Alert (myDate. getFullYear () + "-" + (myDate. getMonth () + 1) + "-" + myDate. getDate ());
MyDate. setMonth (myDate. getMonth ()-1 );
Alert (myDate. getFullYear () + "-" + (myDate. getMonth () + 1) + "-" + myDate. getDate ());
</Script>

Javascript retrieves the date of the day, calculates the week of the Day, and lists all the dates from Monday to Sunday of the week.

As you said, there is no problem. Var date = new Date (); date. setDate (date. getDate ()-1) will automatically change the month year, so you don't have to worry about cross-month and cross-year.
For example, var date = new Date (); date. setDate (1 );
Now it is 2013.3.1, date. setDate (date. getDate ()-1 );
Now it is 2013.2.28
