Forum OpenACS Q&A: Re: assign variables from javascript to openacs

You can attach the OpenACS showCalendar function to a button and ask it to populate a textbox.

I'll use the recommended ad_form Tcl procedure to build the form:

ad_form -name calendar -form {
{start_date:text(text)}
{popup_cal:text(button)
{value " ... "}
{html {onClick "return showCalendar('start_date', 'ymd');"}}
}
}
...

For the showCalendar JS code, see /packages/acs-subsite/www/resources/core.js

For more info on ad_form, see this guide.
