I believe you're hitting the issue I meant to express with that
not-very-helpful comment. You said you wanna write some json, but you're
still defining my_data as a javascript object. Look at line 38 of
ajaxdropdowns.js for a better documented example.
You've defined my_data as a *javascript object*, but the jQuery ajax
function likely is talking about a *json object)* (a STRING representation
of your js object).
I usually use the browsers built-in json to seralize the javascript object
into a string, like this:
var my_data = { id: "12345", tags: "tag1,tag2,tag3" }
$.ajax({
type : "POST",
url : "/my_url/",
data : JSON.stringify(my_data),
contentType : "application/json; charset=utf-8",
dataType : "json",
});
Now, if you truly want to construct my_data as json, it has to be a string,
so this should work too. (Notice the quotes on my_data :-)
var my_data = '{ id: "12345", tags: "tag1,tag2,tag3" }'
$.ajax({
type : "POST",
url : "/my_url/",
data : my_data,
contentType : "application/json; charset=utf-8",
dataType : "json",
});
Yes, this very thing bit me several times until I got my head around it.
Good luck :-)
