AW: [Dojo-interest] Re: How to read the response from dojo bind

[Martin Kluger]

Hello Troy,

if you look in dojo/src/BrowserIO.js in the dojo.io.XMLHTTPTransport.doLoad
method you will see the following snippet (current repository):

---snip---
else if(kwArgs.mimetype == "text/json" || kwArgs.mimetype ==
"application/json"){
				try{
					ret =
dj_eval("("+http.responseText+")");
				}catch(e){
					dojo.debug(e);
					dojo.debug(http.responseText);
					ret = false;
				}
			}else if (
[...]
			}else{
				ret = http.responseText;
			}
---snip---

Returned HTML cannot be converted to a valid js object so the result will
always be false and the server response is lost. Either you extend/modify
the catch statement to return the response anyway (bad idea because you have
to parse in *every* request) or use a text/plain mimetype to
'eval/catch/parse html' yourself if *really* needed (as mentioned by
dustin).

Do you want to stick with the json mimetype even if you want to parse the
returned html anyway?

Regards
Martin
