How to auto populate catalog item variable with current date

[WP2]

Hi ALL,

I have a variable with Date Type and I want the variable to auto populate current date. I used onChange client script with below script but no date populated. Could you please help with a script to achieve this requirement. Thank you.

var dFormat = g_user_date_format;

var tdayDate = formatDate(new Date(),dFormat);

g_form.setValue('todayDate', tdayDate);

javascript:gs.nowDateTime()
