Anthony, what is the difference between

 $.web2py.component(url_materia + '?docente=' + v, 
'evento_materia');
 
and

 $.web2py.component(url_materia + '?docente=' + v, 
'evento_materia','no','no',$('#evento_materia'));

where is the complete syntax about this?
Thanks

Re: [web2py] Re: Help with cascading drop down list

2018-03-03 Thread Val K

just for clarity:
JQuery is a Javascript library. Javascript doesn't have any relation to 
Java. Web2py also has nothing to do with Java. There is a misunderstanding 
when you talk about Java.
And yes, to do what you need, you should have understanding javascript. 
JQuery is quite enough for a simple application with some ajax tricks like 
yours. If you want to develop  a complex application with a rich UI, you 
have to study javascript much deeper, after that you won't have any 
questions about which library/framework  you'd better use (D3, Vue, 
Angular, React, Backbone, Knockout,  Ember ...+tons of others)

Ciao Massimo

Thanks for getting back to me. Where do i start! As a beginner i'm
struggling to understand how i go developing the dependent /cascading drop
down list,  eventually i also want to start using the d3 library with my
app.
There seems to be several concepts i need to learn to be able build the
'drop down' this - i could do with a few pointers - what should i study
other than the web2py book

Should i put my efforts into learn java ,Jquery and ajax, then things will
get clearer?

Sorry if i'm not making sense!

Grazie

 I'm not much of a menu person (I make use of ordinary anchor links for
 the most part), but that example was probably written when BootStrap2 was
 the css/javascript in use.  Currently,  web2py ships with BootStrap3, which
 doesn't support more than 1 level of submenus.  If you use stupid.css (as
 in applications/example), you might not have that limitation, but I can't
 show you what you want.

 Menus typically control what is shown by using javascript to manipulate
 CSS.  Simple menus may be CSS only, but then they'd be statically defined.

[web2py] Re: Back button with an Ajax LOAD page

2018-03-03 Thread Val K

Hi, I think when page is reloaded history.pushState happens too, so there 
are 2 identical URL on the stack after page reloading.
If you want to manage routes by raw JS  It is simpler to use url#hash 
schema  and place  args (category_id=2 and so on) after #.  
In this case it's quite to listen hashchange event and perform ajax.load, 
no other tricks are required.
