Button to fill in the current date into a date/datetime field

[Patrick Nagel]

Hi,

it would be good to have a button next to a date/datetime field that inserts
the current date into the field (via JavaScript). Example: in our Wiki we have
a "Task end date", which should only be filled in after the task ended (so
default value that's set from the beginning is not a solution).
Most of the time people will fill in that information on the same day that the
task actually ends, and then it would be very convenient to just click a button.

Maybe it's not a feature that needs to be in Semantic Forms (although I could
imagine a new parameter that causes a button to be placed next to the date /
datetime input fields).
Can anyone think of another way I could get a button into that form?

I figured out that the HTML/JavaScript would have to look like this:

<input type="button" value="Fill in current date" name="fill_in_enddate"
onClick="mydate=new Date();
document.createbox.input_12_day.value=mydate.getDate()">

- but how could I put this into the form, without making my own new extension,
which I currently consider overkill?

Patrick.

I found the HTMLets extension [1]. Now a file on the Wiki server called
'fill_in_current_date_button.html' contains the code for the button and the
form (at the position where the button should appear) contains
'<htmlet>fill_in_current_date_button</htmlet>'.
