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:
<form enctype="multipart/form-data" action="{{=URL()}}" method="post"
align="left">
<input name="_formname" type="hidden" value="form_main">
<label>Type something and click RUN: <input name="text"
requires=IS_NOT_EMPTY()></label>
<input type="submit" value="RUN">
</form>
<br/>
<div>
{{=msg}}
</div>
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.
