Web2py has a very handy wrapper for ajax, the LOAD() helper.
http://web2py.com/books/default/chapter/29/12/components-and-plugins#LOAD>
The content argument allows you to customize the loading message (by
default, just "Loading ...").
My example:
{{loadmsg = CAT("loading ...", BR(), SPAN(_class="fa fa-spinner fa-spin"))}}
{{=LOAD(c='myhosts', f='myhosts2.load', target='my_hosts', content=loadmsg,
ajax=True)}}
(fa-spinner is an animation available from Font-Awesome-4.3.0 on the web)
When you need to move to fancier stuff, you can also use the jquery and
ajax tools described in
http://web2py.com/books/default/chapter/29/11/jquery-and-ajax>
Hope this helps.

Hi Vineet,
Could you share your successful implementation of the code?
in my controller i have the following:
def index():
msg="wait"
form_main=FORM(INPUT(_type='submit', value="RUN"),
INPUT(_name='text'),
)
if form_main.accepts(request.vars,formname='form_main'):
msg=wait(form_main.vars.text)
return dict(msg=msg)
def wait(some_text):
import time
time.sleep(10)
msg=some_text
return (msg)
in my view:
Type something and click RUN:
{{=msg}}
so basically i have a text box where user enters some text, then the
controller simply takes the text and runs a wait function before returing
the text to view.
I am trying to implement the said loading.gif during the function wait is
on-going.
Could you please advice?
I have very limited knowledge on Ajax.

@juanduke, @Paolo,
Thanks for sharing your time & ideas.
I successfully implemented your idea by juanduke.
The url -- http://www.ajaxload.info/ is excellent.
Regarding Paolo's code, I need to re-structure my code somewhat (which
I will definitely do).
Then I will implement the idea.
In case of any query, I'll post it here.
Thanks again.

Hi Vineet,
as juanduke has suggested, I use the following jquery function (I put it in
web2py_ayax.js) instead of standard w2p ajax function to show a loading
image:
function web2py_polling(u,s,t){
$('#'+t).html('');
ajax(u,s,t);
}
Of course you can set some css rules to custom div#loading_gif_container.
How to use:
I insert at the bottom of the view :
//
### controller ###
def get_output():
the_output = "I'm the output"
return the_output
You could also use a standard ajax call to a function that returns
web2py_polling function that, optionally, calls another action.
For example:
### in the view ###
//
### controller ###
def get_output():
# make evaluation
return "web2py_polling('another_action',[args],'output_target');"
def another_action():
the_output = "I'm the output"
return the_output
Ciao.
Paolo
