Diference between PHP's echo and webpy function's return?

[Tomas Schertel]

I'm trying to implement a dynamic dropdown with web.py but I can't get it working.
I'm using this tutorial: http://css-tricks.com/dynamic-dropdowns/
I'll try to explain what happens...
I made a test page that returns my database select. My GET function returns this on screen AND as page's source:

<option value="chips">Chips</option><option value="cookies">Cookies</option>

When I browse the tutorial's PHP page [1], this page shows this:

Coffe
Coke

But page's source is this:

<option>Coffee</option><option>Coke</option>

My dorpdown doesn't work at all.
Maybe someone has had some similar problem.

Thanks.

Can you post the full HTML code generated by your database select ?

I've looked into the PHP tutorial, and it's seems, that it's skipping a lot of HTML code and goes straight to the point, how you get records from the database.

It's also skipping the point, that you need to use <select</select> for a dropdown to be even initialized...

<option value="chips">Chips</option><option value="cookies">Cookies</option>

Thanks...

wait; You're telling us, that the output is correct.

What does the "doesn't work at all" means in this context? Do you have any javascript errors, since I can somehow assume, that you pull the content from the web.py page result; Look into your javascript page.

I don't know how it can influence, but my python code returns the same in page and in sources:

<option value="chips">Chips</option><option value="cookies">Cookies</option>

The http://css-tricks.com/examples/DynamicDropdown/getter.php?choice=beverages select returns two different thigs:

Coffe
Coke

Is shown in page. But page's source is this:

<option>Coffee</option><option>Coke</option>

[Primoz Anzur]

Um.

You still haven't elaborated what "doesn't work" means in this context. Explain what exactly doesn't work and how it doesn't work...

When I browse my select url, I got

<option value="chips">Chips</option><option value="cookies">Cookies</option>

And I see in web.py's internal server a 200 - OK status.

But somehow this result doesn't populate my second dropdown select.

[Primoz Anzur]

Welp;
If the second dropdown isn't populated is because there's an error in Javascript. Equip Firebug and monitor request calls and see what's going on. 

You might also want to look at Web Developer's toolbar to quickly take apeek into if you have any JS errors and such.

+10 for Firebug - I couldn't survive without it.

I'll use firebug.
