i cannot seem to get any data from my ajax request for a json file.
the following function is called on an onClick:
===============================================function loadBulletin(period) {
filetoget = "content/home/bulletin.txt";
new Ajax.Request(filetoget, {method:''get'', onSuccess:
function(transport, json){$(''main_text'').innerHTML
json.bulletin[1].title;}});
}
===============================================
the file bulletin (my json file) looks like this:
==============================================={"bulletin":[
{"date":"3/2/2007","time":"8PM","type":"Class","title":"Jnana
Yoga","speaker":" ","location":"Old
Temple"},
{"date":"3/3/2007","time":"8PM","type":"Class","title":"The
Gospel of
Sri Ramakrishna","speaker":"
","location":"Vivekananda Hall"},
{"date":"3/4/2007","time":"11AM","type":"Lecture","title":"Be
Thou a
Witness","speaker":"
","location":"NT"},
]}
================================================
my main_text div has a default value of some text that is from the
html on the original page. even after pushing the button, the text
stays the same (which is nothing like what should be coming from the
file). there are no errors being thrown in the error panel. i have
tried a zillion things but will try anything else at this point. if i
replace "json.bulletin[1].title" in the code above with some string,
it prints in the div just fine, so it looks like my ajax request is
returning a success flag. wouldnt json.bulletin[1].title return "The
Gospel of Sri Ramakrishna" based on my file above?
can anyone suggest what is wrong with my code?

Hi Vance,
Unless you''re using the AJAX branch, which does feature JSON evaluation
for the response body, the "json" argument you have relies
exclusively,
for now, on the X-JSON header.
I assume your JSON file is passed (as it should be) in the response
body. If you''re clean, you served that response with a JSON MIME type,
too.
At any rate, what you need to get it working on 1.5.0 then is to
manually eval your responseText, preferrably wrapped between
parentheses. Something along these lines:
...
onComplete: function(transport) {
var json = eval(''('' + transport.responseText +
'')'');
// rest of your code here
}
I believe that should do it.

thank you. thank you. thank you. the documentation is a bit misleading. the api docs say the following under ajax requests: "Any response whose MIME type is missing or JavaScript-related will automatically be passed to eval." i hope my hair grows back. grin.

Hi Vance, I suggest you download the release candidate to version 1.5.1 and use the new built-in JSON parser instead. Here''s the link to the release candidate announcement: http://prototypejs.org/2007/3/9/prototype-1-5-1-rc1 and here''s the link to the JSON tutorial: http://prototypejs.org/learn/json Hope this helps.
