script to set the date in a field to prior day

[giovanni3]

Any javascript gurus out there that can provide a script that would set the default date in a "date" field for the prior day?

Hello Giovanni,

You can set the dictionary default value as javascript:gs.daysAgoStart(1);

Please check section 2.15 in below wiki link for more details.

If you want to take the time zone into consideration, set the default value to:

For a Date field:

javascript:var gdt = new GlideDate();gdt.addDays(-1);gdt.getDisplayValue();

For a DateTime field:

javascript:var gdt = new GlideDateTime();gdt.addDays(-1);gdt.getDisplayValue();

The "getDisplayValue()" is the trick if you want to use the current user's time zone.   Otherwise you will get the date in GMT, which could be an issue.
