[web2py] Re: I am unable to parse contents from a json view in javascript? How do I do it?

[Leonel Câmara]

Seems like you're trying to make a phonegap/cordova app, the easiest way to 
go around the CORS problem is to simply put the web version of your app 
inside web2py's static folder. As a packaged application on your phone you 
will not have this problem.

In the future, please explain in more detail what you are trying to do and 
show any code you have tried along with any error messages.

Note, browsers will not allow you to make Ajax requests to other domains 
(i.e., cross-origin requests) unless CORS has been set up with those 
servers (do some research on CORS).

An alternative is to make an Ajax request to *your own server*, and have 
your server then make the request for the resource in question and simply 
pass it back to the browser.

Yeah exactly that doesn't work. How do I avoid that error? It says:" 
XMLHttpRequest cannot load 
https://biglibrary.pythonanywhere.com/app/phonegap/temp.json. No 
'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'null' is therefore not allowed access." when I use your code 
snippet.

$.getJSON("https://biglibrary.pythonanywhere.com/app/phonegap/temp.json 

").then(function(data) {
alert(data.message);

});

Note that you may have problems with Access-Control-Allow-Origin

If you have that as a string in Python and want to convert it to a Python 
object (i.e., a dictionary):

import json
mydict = json.loads(my_json_string)

Hi Dave. for example how do I read the json from this 
link: https://biglibrary.pythonanywhere.com/app/phonegap/temp.json

A code snippet will be of much help.
Thanks. :)

How so?  What does it do?  What do you expect it to do?

Can you show us how your controller prepares the json?  What does your view 
look like?

It's messed up.
Can you help out with a code snippet? Will be of much help.

What do you mean? What are you trying to do? How are you putting the json 
there? Are you getting it using $.getJSON or something like that?
