html tags and python

[Hansan]

Hi all

I am making something for my webpage

Where the user can choose a month: I have made that with a dropdown box.

<select>
<option name = "1" value="1">Janua ry
<option name = "2" value="2">Febru ary
<option name = "3" value="3">March
<option name = "4" value="4">April
<option name = "5" value="5">May
<option name = "6" value="6">June
<option name = "7" value="7">July
<option name = "8" value="8">Augus t
<option name = "9" value="9">Septe mber
<option name = "10" value="10">Octo ber
<option name = "11" value="11">Nove mber
<option name = "12" value="12">Dece mber
</select>

The thing is:
I also want the user to choose a date
I will make this with another dropdownbox.
But if the first month is selected, then there should be 31 days in the days
dropdownbox, if the second month is selected there should be 28 days in the
dropdownbow.

I Know a little of python programming, but not to much, I have a feeling of
that I should use a cgi, can any explain me what I have to do :? Or give me
a link to a site where I can copy the code for it

All help will be greatly appreciated.

Thanks for your time

Python is great, but I'd suggest trying this with JavaScript and the DOM (Document Object Model). In fact you may be able to Google-up a JavaScript script that does what you want. JavaScript executes on the client machine, which is perfect for that aspect of your application.

The general idea would be to have the script redefine the option values fordays upon selection of the year and month. The DOM lets you access those <option>s at run time very easily.

JavaScript is not as robust a programming language as Python, but it is handy for executing certain functionality within a browser interface, and because it works within the browser and can access the DOM, there is an elementof instant gratification.

Then... about the time you start to try to build a real application with JavaScript, it will start to drive you mad... and you will have a new, greater affection for Python.

Actually, if you dig into it really hard, it's not bad. In fact of all the
languages I know, Javascript is probably the closest to Python circa 1.5.2
that I can think of. Not identical, and it doesn't have *any* of the later
nice things in Python (metaclasses, descriptors, list comprehensions,
etc.), the OO can be clumsy (though it is fairly functional), and there
are inconveniences that I really wish I could make go away, but it's not
too bad.

(The worst being that

for (var something in someArray) {}

gives you the *indices* of the array, not the values, so the next line is
almost always

var theActualStinki ngValue = someArray[something];

..)

The DOM is clumsy, but for any given browser not to bad. The *differences*
in the DOMs from browser to browser are what kill you. And of course, no
real "libraries" .

Hi and thanks for your replies.

Will one still tell me how I use the timedate modul with my form

print '''<form action='inserte vent.py'><br>
<p>Day (1-31):<br> <INPUT type="text" NAME="day">
<p>Month (1-12):<br> <INPUT type="text" NAME="month">
print '''<p><input type=submit value='Submit'> </p></form>'''
------------------------------------------------------------------------------------------
It is starting to make a little sense. But its still not that clear...

If I import the DateTime or install and import the mx package.
Where should I then change something in my code?
I guess that I will have to see if the entered number is valid when the user
clicks the submit button.
So it must be when I run my insertevent.py script.
So will I have to import the DateTime modul in my form.script or in my
insertevent.scr ipt

And this maybe sound stupid, but will one pls give me an example of what the
code could be for maybe January and February.

I just cant figure out how they work together, the DateTime modul and the
html form.
The user can enter a number in the month field and in the day field. Then
there have to be a tjeck to see if the entered numbers are valid. If the
number entered in the month field is 1 and the number entered in the day
field is 32, there have to come anerror report, and the user will get a
second try to enter the right numbers.

And then if the entered numbers are correct, the data will be inserted in
the database ( But I will work on this if condition myself, I think I can
figure that out:)

Do you know what I should google after, which key words ?

"free javascript calendar"

These look interesting:

IMHO, using Javascript is a better idea for this particular purpose
instead of writing a lot of checking in Python.

I figured it out with a lot of if else statements, but still if one have
time to explain how the time/date modul works with forms, I will be more
than happy to lear.

Thanks

I know this isn't the solution to your problem (the solution would be to use
JavaScript), but if I was a user, I'd rather type in the day number myself than
have to choose from a 31-long dropdown. Why don't you just give the user a text
field and then validate the input.

Just my 2 cents..
