Re: [web2py] Re: Pass multiple arguments to URL through javascript
Try this it'll give you a form, intercept the form submission and instead
do an ajax call to the validate page which checks the email and password
and if that's correct will return True and the page will get forwarded via
JS to the next page with your email password in the URL as args.
Why do the redirect via javascript rather than just having the controller
do the redirect though?
Controller (default.py)
-
def index():
example action using the internationalization operator T and flash
rendered by views/default/index.html or views/generic.html
response.title = Passing Args to URL through JS
response.subtitle = T('Home')
form = SQLFORM.factory(
Field('email', 'string', requires=IS_NOT_EMPTY(IS_EMAIL())),
Field('password', 'string', requires=IS_NOT_EMPTY()),
_name='foo_form', _id='foo_form')
return dict(message=T('Demo'), form = form)
def validate():
import gluon.contrib.simplejson as sj
print request.vars
print request.args
try:
if request.vars.email == 'm...@email.com' and request.vars.password ==
'mypassword':
#success
return sj.dumps(dict(success=True, message='Success!'))
else:
#fail
return sj.dumps(dict(error=True, message='Oops wrong login
info!'))
except:
#fail
return sj.dumps(dict(error=True, message='Login Failed, Please Try
Again!'))
def receiving_page():
response.title = Passing Args to URL through JS
response.subtitle = T('Results')
#get passed args
email = request.args[0]
password = request.args[1]
return dict(email = email, password = password)
View (default/index.html)
{{left_sidebar_enabled=right_sidebar_enabled=False}}
{{extend 'layout.html'}}
h1{{=message}}/h1
{{=form}}
div id=statusPlease Login/div
script type=text/javascript
$(function() {
$('#foo_form').bind('submit',function(event){
var email = $('#no_table_email').val();
var password = $('#no_table_password').val();
alert(Submitting +email+ +password);
$.post('{{=URL(r=request, f=validate)}}',
$(this).serialize(),

It depends. Here's one example:

When the page is loaded, the href of the mylink anchor tag will be

appended. Of course, you'll need some way to set the values of param1 and
param2, and there may be some other event that should trigger the

Re: [web2py] Re: Pass multiple arguments to URL through javascript
Well honestly if it was a dynamic link I wouldn't even use URL as good
style of JS programming is putting the code in a .js if this is the case
then the web2py parser cannot even access the URL to parse it. (At least I
have never been successful with that process.)
If they are getting the params at a later time and in a js file there is no
need in using the URL just use url = '/path/' + param + '/' + param; The
only problem with this is if he changes the path, however if he changes the
path he would be required to update URL() anyways.
I have fell into the trap on trying to rely on the helpers to much myself
in the past. Some places in your code you shouldn't use them. Trying to use
them for everything kind of forces you to change your logic to bend around
web2py instead of having web2py work with your logic. Also whenever you use
URL instead of the direct url='/path' the framework is forced to do more
function calls, in some situations like this one it isn't really worth
having the extra function call and it is actually more typing :D

Re: [web2py] Re: Pass multiple arguments to URL through javascript
thank you for your interest.
let me brief what i am doing. I am building an application accessing google
maps api v3. I need the function that decide if a certain point is within
certain bounds. my understanding is that i need to do that in the view ( by
passing the point and the coordinates of the bounds ). the view js can
access them if they in {{ }}. then I need to return the output of the
function to the next action, by clicking
h3 {{=A(' . ',_href=URL('action'))}}/param1/param2 /h3
it did not work (it does not write the values of param1 and param2 )
and
h3 {{=A(' . ',_href=URL('action',args=[param1,param2]))}} /h3
is not working ( param1, param2 is not defind within {{ }} )
is there a solution without using jquery?
Re: [web2py] Re: Pass multiple arguments to URL through javascript
You do realise that you are missing the closing ?
h3 {{=A(' . ',_href=URL('action'))}}/param1/param2 /h3
Also what you are trying to do in this code will never work.
h3 {{=A(' . ',_href=URL('action'))}}/param1/param2 /h3
becomes
h3 a href='/action'/a/param1/param2 /h3
Try this:
h3a href={{=URL('action')}}/param1/param2/a/h3

Re: [web2py] Re: Pass multiple arguments to URL through javascript
I wasn't suggesting he should use the URL() function, just pointing out
that it *can't* be used to build a URL on the client side, and showing a
simple example of how to build a URL on the client side via Javascript (use
of the URL() function was incidental and not central to the point of the
example). In any given case, it may or may not make sense to use the URL()
function to build the base URL (vs. hard-coding it in a .js file), and I
wouldn't state a blanket rule either way (if you're using the web2py
rewrite system, it's generally a good idea to use URL() whenever feasible).
Also, I hadn't realized you made an update to my code example. The update
wouldn't work because it attempts to put Javascript variables inside Python
code that must be executed on the server.

What do you mean by needing to do that in the view? Do you mean in the
browser? If so, that's not the same thing as in the view. In web2py, the
view is a special template that can include Python code. The view is
executed on the server, and the output of that execution is what is sent to
the browser. The browser does not see any of the Python code (i.e., none of
the {{...}} end up in the browser).
is there a solution without using jquery?
It's still not clear what you are doing. What are param1 and param2? Are
they determined dynamically within the browser? If so, you'll need
Javascript to build the URL in the browser (it doesn't have to be jQuery
specifically, but some form of Javascript). If param1 and param2 are known
on the server at the time the page is being constructed by web2py, then you
can simply include them as args in the call to the URL() function.

Re: [web2py] Re: Pass multiple arguments to URL through javascript

and
h3a href={{=URL('action')}}/param1/param2/a/h3

You are simply putting the literal strings param1 and param2 directly
into your HTML there, so of course the values of those variables won't be
shown. What are param1 and param2? Are they Javascript variables? If so,
where are they defined? If they are Javascript variables, then you have to
use Javascript to build the URL -- you cannot just paste Javascript
variables directly into HTML and have the browser translate them into their
values.
Anthony
Re: [web2py] Re: Pass multiple arguments to URL through javascript
If param1 and param2 are from javascript:
1) You can not write the code in headers as you have current written you
will have to use something like the following:
h3a id='url_with_params'/a/h3
// javascript function:
function generateURL(param1, param2) {
url = '/action/' + param1 + / + param2;
$(url_with_params).attr('href', url);

Secondly, if I want to pass arguments by name, would it be okay to do

Almost. You want:
{{=URL(...)}} + '?p1=' + param1 + 'p2=' + param2
...then look for p1 p2 in request.vars.
