Getting json after an ajax call

Hi folks,

I can't retrieve a json from the server. I have an ajax call, on success I want to get some json in return.

Here is a sample code:

html jQuery ajax
callback: [ ... ] ;
onSuccess:
(html jQuery getJson
json: [ :js | js object:[(Dictionary new at:'aSampleKey' put:'aSampleValue'; yourself) asJson] ];
onSuccess: 'console.log(arguments[0])')

Unfortunately the console prints Object {}

I guess there is something wrong with js object:[] but I've no idea of what

try

'console.log(JSON.stringify(arguments[0])'

errr... missing closing parenthesis in the previous email

'console.log(JSON.stringify(arguments[0]))'

Re: Getting json after an ajax call

Hi Paul,
No change. The console shows {}

I was expecting {"aSampleKey":"aSampleValue"}

Re: Getting json after an ajax call

Dave,

You are mixing the use of the JSON canvas api and the conversion of Smalltalk object to JSON.

Take a look at an example in JQJsonFunctionalTest>>renderJsonCallbackOn: or in WAJsonRenderingTest

Either do:

js object: [ js key: ‘aSampleKey’ value: ‘aSampleValue’ ]

or:

js render: (Dictionary new at:’aSampleKey’ put: ‘aSampleValue’; yourself)

The first one uses the json canvas api to directly generate JSON on the document. The second one renders the JSON representation of Smalltalk objects on the document.

cheers

Johan

Re: Getting json after an ajax call

Thanks Johan, now it's clear.

I had previously looked at JQJsonFunctionalTest>>renderJsonCallbackOn: but it didn't clarify a lot.

WAJsonRenderingTest is not in the 'Base' Seaside package, I had to download the full one

Gofer new
url:'http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main';
package: 'ConfigurationOfSeaside3';
load.
((Smalltalk at: #ConfigurationOfSeaside3) project version: #stable) load: 'CI'.

Thank you very much
Dave
