Re: [web2py] Re: web2py ajax function in py4web
Also, Stifan, could you post a few use cases? py4web includes vue.js by default and I am trying to understand the most common use cases of this for documentation purposes. I am guessing: - Instant form update on client side when a value is changed (for example, a star rating or even a complicated dialog) - Instant form update on client side when a database value is changed (for example, adding a line item to an invoice) Note to py4web peeps: Stifan is a gifted web2py person and I am delighted to see him posting here! -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Re: web2py ajax function in py4web
Stifan Can you post this in the py4web group? In py4web we don't include any jquery components. The goal is to be as light as possible and require as few additional packages as possible. I think you'll get better visibility on the py4web list to get this question answered. I know there are some javascript utilities provided with py4web but I haven't used them yet. -Jim On Saturday, November 7, 2020 at 5:16:01 PM UTC-6, 黄祥 wrote: > > > http://web2py.com/books/default/chapter/29/11/jquery-and-ajax#The-ajax-function > how to achieve this in py4web ? > > thx n best regards, > stifan > -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] AJAX function
I've got a fairly substantial page with a lot of data in it that I don't want to keep reloading the page so I'm using the AJAX function provided with web2py and pulling the data from a SQLFORM used in the view page. Question I have is, I'm using validate_and_insert function, I was wondering is it necessary to escape the input on the server side first before the validation_and_ insert function?

[web2py] Ajax function
Hello,
this is my *view*
on the *controller *I build a function containing the folowing code:
pippone='ciao'
stringa.append("jQuery('#paginatore').html('%s');" % pippone())
print pippone
return stringa
The console says
ciao
(the HTML generated appears to be right)
When the function returns, I expect the new anchor to appear in the
"paginatore" div, but it doesn't. Anybody can suggest me why?

[web2py] ajax function is not called when passing non-ascii characters as arguments
On my page I have a set of links (page types) that loads its content
dynamically when user clicks on the link. Clicking on each link calls a
"LoadPage" javaScript function that calls python function that loads page
content and puts it in "pageType" DIV.
function LoadPage(pageType)
{
ajax('{{=URL("default", "ajax_LoadPage")}}' + '/' + {{=user_id}}
+ '/' + pageType, [], pageType);
}
Called ajax function users request.args[0] to retrieve pageType.
if "pageType" is ascii string (i.e: "default/ajax_loadPage/1/Kalc") then
page is loaded without problems. But as soon as non-ascii characters are
introduced as args (i.e:"default/ajax_loadPage/1/Kalč") ajax function is
not called.
Is there a way to call ajax function this way and function and pass it a
non-ascii argument?

[web2py] Ajax function and returning Row, not string
I'm building a cascading dropdown lists. I use web2py ajax function to do
it. My code:
select 1 (parent):
{{=OPTION('-- Choose department --', _value="")}}
{{for d in departments:}}
{{=OPTION(d.name, _value=d.id)}}
{{pass}}
select 2 (child):
{{if request.vars.department:}}
{{for r in ranks:}}
{{=OPTION(r.name, _value=r.id)}}
{{pass}}
{{pass}}
controller function:
def rank():
ranks = db(db.rank.department_id ==
request.vars.department).select(db.rank.id, db.rank.name,
orderby=db.rank.name)
return ranks
Ajax function calls *rank *function and passess value of the currently
selected option in *department *select (parent). Then, the function assigns
DAL query to *ranks *and returns it.
The thing is that *ranks *is a string when returned. My for loop in the
select 2 is ommited and the its example result code looks like this:
"rank.idrank.name137Chief Cook138Chief Steward139Cook
Assistant140Messman136Second Cook141Steward"
So it LOOKS like a Row object but it's a string obvioulsy - and so I can't
get any Row data out of it (r.name, r.id).
Begging for help her :)

[web2py] ajax function in a grid, I'm getting None in a request.vars
I'm trying to learn more about LOAD and ajax.
I have an SQLFORM.grid loaded as a component. It's read only.
I've added a button to each row using
links = [lambda row: INPUT(_name='toggle',_type="submit",_value="Toggle",
_onclick="ajax('toggle_order_import_v2',['id']
,':eval')")])
Each row of the grid indeed has the record ID in a column called ID. The
"toggle" flips a boolean field.
The generated HTML looks fine: this is the button
the function toggle_order_import_v2() is in my controller.
it updates the database, so I want to refresh the LOADed sqlform.grid with
the returned ':eval' JavaScript... I haven't got to that yet.
The called function first does
id = request.vars.id
as preparation for updating the record matchting the grid row.
but via the debugger I see that this is evaluating as None, which surprises
me; I expect the ID of the row.
I see there are some threads on action buttons using the A helper but I was
hoping to learn how to use the ajax function, which sounds like it should
work in this situation.
(My legacy code does not use LOAD and the button uses a A tag; the legacy
'toggle' controller updates the database and then uses redirect to reload
the page. It works, but it's slow (and worse, user filters applied to the
grid are reset)
When I put the SQLFORM.grid in a component but keep the legacy 'toggle'
code, the redirect breaks, which is why I want to go 100% AJAX)

where the 'name1' 'name2' are defined as ids of an input fields.

[web2py] ajax function with eval : return js function from controller
In layout.html, I have
{{response.files.append(URL(r=request,c='static',f='js/xyz.js'))}}
xyz.js contains a function abc(x){ code line1; code line 2;
In a View, there is --> ajax('{{=URL("salhead_edit")}}, [],
':eval');
"salhead_edit" returns js function --> 'abc(myvar1)'
But it is not evaluated in View.
(I am sure that the js file is correctly referenced in layout.html)
Note: If I directly return the "code line1; code line 2;..." from the
controller, they ARE evaluated.
But "function abc()" is not evaluated.
Is it expected behaviour of the ajax function?

Exactly reproduced the code from web2py book.

[web2py] ajax function returns None
Hi,
I have tried the example from chapter 10.3 The ajax Function
Controller:
def one():
return dict()
def echo():
return request.vars.name
one.html:
{{extend 'layout.html'}}
No success, because the value of request.vars.name is None
Just for fun I have tried "request.now", "request.extension",
"request.folder" and so on instead of "request.vars.name" - these examples
worked fine, but I had no chance to get the value of name.
Version: web2py 1.98.2, started from source with Windows Python 2.7.2
and web2py 1.98.2 Python 2.5
What is wrong - any ideas?

[web2py] ajax function submit on script
hi,
is it possible to put ajax function submit on script?
e.g.
jQuery(document).ready(function(){
jQuery('.view').click(function()
{jQuery('.comments').slideToggle()});
jQuery('.post').click(function(){jQuery('.form').slideToggle()});
jQuery('.post').submit(function(){ajax('blog_show', 'comments
hidden')});
});
i've already tried it, no error occured but the ajax function didn't
work. my intention is when a user submit a comment form (using crud on
controller) it will show without reloading the page, or is there any
others way to do this?
please give an advice and please correct me if my code is wrong.
many thanks before

[web2py] ajax function target id null
Hi,
I use the ajax function as follows:
ajax('func1', ['id1'], '')
because I don't need to send some value to the html page, so I set the

'document.getElementById(...)' is null or not an object.
How can I use the ajax function when I don't want to send values to
html page?

Not sure what you mean by

the second argument of ajax had to be a list of IDs if fields.
The values of those fields will be passed.
