Let me go over this quickly:
> var data = $.toJSON( ....# I convert JSON object to simple text
here you create a JSON encoded 'data' object, which is in line with
the following jQuery (Javascript) code:
> $.ajax({
> type: 'POST',
> url: '{{=URL(r=request,f='action')}}',
> contentType: "application/json;
> charset=utf-8",
> data: data,
this means that you will be sending a JSON encoded 'data' in the
request body of a POST to your action (hence the need for sj.loads
(response.body.read()) on the server side). Side note: this is in
contrast to a GET method which encodes 'data' in a query string.
> dataType: 'json'
this means you expect the response from the server to be in JSON
> success: function(data){ {{
this function is called when the ajax request finishes successfully
and 'data' will contain the response from the server (should be in
JSON as specified above, so somewhere in your action you have to make
sure it is).
Your success function has to manipulate 'data' using Javascript (not
Python) to obtain the info you need.
> import
> gluon.contrib.simplejson as sj
> data = sj.loads
> (response.body.read())
> value = data
> ["Name"][0]["key1"]
> }}
> alert({{=value}}); }
> });
> });
>
> }
Hope this helps.
