[web2py] Re: Ajax function
You're using eval, but are you returning executable javascript from your
function 'paginatore' ?

[web2py] Re: Ajax function and returning Row, not string
Yes, my assumption was incorrect. I thought ajax() would return a Row
object to my ID target element, so then I could use it within the element.
"I have never been so wrong".
Well, it works now:
controller:
def rank():
ranks = db(db.rank.department_id ==
request.vars.department).select(db.rank.id, db.rank.name,
orderby=db.rank.name)
result = ""
for r in ranks:
result += "" + r.name +
""
return XML(result)
view:
{{if request.vars.department:}}
{{=XML(result)}}
{{pass}}
- it did the trick. The rest of the code is the same.
Cheers.

[web2py] Re: Ajax function and returning Row, not string
Well, you're doing it wrong.
I mean, the way you are calling the ajax function...
ajax('rank', ['department'], 'seafarer_experience_rank');
What that does is calls 'rank' with the argument 'department' and replace
the contents of the element whose ID is 'seafarer_experience_rank' with the
results. In this case, it's wiping out your:
{{if request.vars.department:}}
{{for r in ranks:}}
{{=OPTION(r.name, _value=r.id)}}
{{pass}}
{{pass}}
And replacing it with the dict that is returned from 'rank'. You probably
want the 'rank' function to return your HTML that you want.
Or you should use a javascript templating library (such as jqote2) to take
your data (returned as a dict) and turn it into html.

[web2py] Re: ajax() function doesn't work properly (returns parent page)
Try going to http://127.0.0.1:8000/inventoryapp/default/index/ (note the
trailing "/"), and you should see the same problem. On the storeadmin page,
the problem should go away if you exclude the trailing "/" from the URL.
The problem is, in the call to ajax(), the URL is just 'echo'. Because it
doesn't start with a "/", the browser interprets that as being relative to
the current URL path, which it assumes ends after the last "/". If the
current URL ends in a "/", the browser just adds "echo" to that and makes
the Ajax call to the current URL (web2py will just see "echo" as a URL
argument rather than a function). If you check the network traffic on the
storeadmin example, you should see the Ajax call going
to http://127.0.0.1:8000/inventoryapp/default/storeadmin/echo.
The best approach is to use the full URL in the Ajax call, using the URL()
function:
_onkeyup="ajax(%s, ['keyword'], 'target');" % URL('default', 'echo')
We should probably change that in the book.

[web2py] Re: ajax function with eval : return js function from controller

Seems that I need to return js code lines (not js function) from
controller & get going ahead.
btw, I have found one line jquery code for selecting value of select
box.
"$('#element_id option[value=%s]').attr('selected', 'selected');" %
adict['key']

Seems that I need to return js code from controller.
btw, I have found a one-line jquery code for this-->

dict_obj['key']
This works & I will proceed with this, for time being.

I checked the js returned from controller function.
It is
selbx('edit_freq','daily');
selbx function is there in the View.

[web2py] Re: ajax function with eval : return js function from controller
Something is wrong in the function.
I defined a test js function in View.
function alrt(mesg) {
alert(mesg) };
And in Controller,
return "alrt('Hello World!');"
It works.
The actual js function is---
(it sees which value of select box matches the one returned from
controller; then sets the value of select box to that value).
function selbx(elementID, value_returned_from_dataset){

OK, but same problem -- 'myvar1' isn't a javascript variable either -- it
is a string identifying an html element. So you would still have to return
'abc("myvar1")', or maybe 'abc("#myvar1")', depending on how you are using

It is a typo here. It is correct in actual code.

'myvar' is a not a python variable.
I pass the id of html element as argument.
Javascript code sets the value of that html element.

from controller (the way I did), provided that I adhere to your hints.
Perhaps then, why my code is failing to evaluate js function in View?

Probably a typo, but missing the closing single quote (') after the }} for
the URL.

Unless 'myvar1' is a variable already defined in javascript somewhere in
your page, that won't work. If 'myvar' is a Python variable, you're going
to have to insert its actual value (in quotes if it is a string) into the
JS code. Remember, from web2py's perspective in the controller, the JS code
you're building is simply a string -- it doesn't know it is code. Something
like:
myvar1 = 'whatever'
js = 'abc("%s");' % myvar1
will return:
abc("whatever");
Note, it's a good idea to add the ";" at the end of the line.

Hi juanduke ! Thanks for the tip. It worked. I will do some more complicated work on this now. Cheers, Vineet On Oct 6, 5:03 pm, juanduke wrote: > Hi Vineet: > > You need to change this line; > > > > for this line: > > > > (change id='name' for name="name") > HTH!!! > Bye

Hi Vineet: You need to change this line; for this line: (change id='name' for name="name") HTH!!! Bye
Re: [web2py] Re: ajax function returns None
Sorry, my mistake...
It works!
There has been a file "one.html" and another file "one.html.bak"
The editor opens "one.html.bak" (why?), but web2py uses "one.html" (of
course!)
Thnak you very much!

Re: [web2py] Re: ajax function returns None
Now I have tried:
{{extend 'layout.html'}}
Sorry, same result: "None"
echo is called, but request.vars does not contain any value.

I think this is typo in the book.

Re: [web2py] Re: ajax function submit on script
thank you so much for your correction, massimo. it runs right now with:
jQuery(document).ready(function(){
jQuery('.view').click(function(){jQuery('.comments').slideToggle()});
jQuery('.post').click(function(){jQuery('.form').slideToggle()});
jQuery('.post').submit(function(){ajax('{{=request.controller}}', [],
'comments hidden')});
});
it seems for the first, second and third data inserted the ajax function is
not running properly, i mean, i must refresh the browser, but after the
third data, ajax function is running smoothly, where is my wrong code that i
must fix it?
currently i separate the javascript into the static js folder like code
above, and call it on the views.
thank you very much before

[web2py] Re: ajax function submit on script
yes but the syntax is incorrect:
ajax('blog_show', 'comments hidden')
should be
ajax('blog_show', [], 'target_id')

[web2py] Re: ajax function
You can add the constant as an arg but to the url.
Also note that components, i.e. LOAD(), allow args and vars.

Make an 'hidden' input field.

[web2py] Re: ajax function
I need to use ajax web2py function passing a costant, es.:
ajax(url,[ 'namefld1', 'namefld2', 'costant-value'], ':eval')
Exploring code I see that I must insert an input tag with desidered
value and call it by name.
There is a smarter way?
Thanks

[web2py] Re: ajax function
Could you be a little more specific? Are you trying to pass args and vars?
Or are you trying to load HTML using AJAX and sending it to a target DIV? If
you are using web2py's ajax function, you may be limited to what you can do.
Worst case, you can always try calling jQuery's load() method:
var url = {{=URL('ajax_view.load', args={'arg1': 'my', 'arg2', 'value'})}};
jQuery('#target').load(url);
Or like this:
var url = {{=URL('ajax_view.load')}};
jQuery('#target').load(url, {arg1: 'my', arg2, 'value'});
Does this help?
[web2py] Re: ajax function target id null
You cannot but if you do
ajax('func1', ['id1'], ':eval')
it will interpret the returned page as json and evaluate it. id If you
return 'null' or '', it should work as expected and not raise any
error.
