Defaulting Date to a specific weekday

[dstafford]

OK... lots of date examples and guides however I have not been able to find some guidance getting a calendar/date field to default to the most recent Sunday date. This is a calendar script I have in a web page. So if it is Tuesday I would like the default date to reflect the previous Sunday. The basic code n the web page is the following.....Week Ending Date (Sunday Only): <script>DateInput('txtWeekEnd',true, 'MM-DD-YYYY')</script>This calls 'calendarDateInput.js' is a script that processes a drop down calendar that dates can be selected off.... Anyone have any thoughts???Appreciate your input..... Thanks

You could check out the mysterious strtotime() function.

<?php echo(strtotime("last Sunday")); ?>

Edit:Oh, sorry, that's PHP.What you'd have to do in Javascript is to keep subtracting 1 to the day until the specified day is Sunday.Something like this:

var d = new Date();while(d.getDay() != 0) {  d.setDate(d.getDate() - 1);}

That's great thanks..... I appreciate the help.

Slightly optimized...

var d = new Date();var day = d.getDay();if(day != 0) {	d.setDate(d.getDate() - day);}
