dojo dijit.form.select : getting data out of the dataStore?

Question

I am using dojo and want to populate a dijit.form.select widget from a dataStore (this works). Whenever I make a selection in the select-widget, other fields from my dataStore should be read and then be displayed in the textBoxes on the page.

Unfortunately I dont know how to read the other fields from my data store. Here is my code:

The important stuff happens if you scroll all the way down.

Here is the javascript Object which is then read into the dataStore:

  var jsonData = {"identifier":"name",
                  "label": "subject_main",
                  "items": [
    {"name":"departure",   "subject_main":"123",  "subject_1":"sub1", "subject_2":"sub2"},
    {"name":"direct",       "subject_main":"456",  "subject_1":"sub1", "subject_2":"sub2"},
    {"name":"Messaging",           "subject_main":"789",  "subject_1":"sub1", "subject_2":"sub2"},
    {"name":"exchange",      "subject_main":"1011", "subject_1":"sub1", "subject_2":"sub2"},
    {"name":"Zilo",                "subject_main":"1213", "subject_1":"sub1", "subject_2":"sub2"},
    {"name":"Stub_implementation",            "subject_main":"1415", "subject_1":"sub1", "subject_2":"sub2"},
    {"name":"Standard_implementation",  "subject_main":"1617", "subject_1":"sub1", "subject_2":"sub2"}
                        ]};
  </script>

For ex when I select "name":"Messaging", "subject_main":"789", "subject_1":"sub1", "subject_2":"sub2"

Messaging should be displayed in my dijit.

You are doing it a funny way ! Why do you define the store using a span Element ?

Take a look at this post:

Dojo how to get JSON attribute from dojo.data.ItemFileReadStore

UPDATE:

Thats how you should do it:
