Question

ColdFusion JSON parsing failure: Expected '"' at character 2: '&'

Hello, all,

I'm trying to convert a project so that the components folder is outside of the webroot.  For the most part, this has been a smooth transition.

Until (dun dun dunnnnnnnn) I get to the parts where I am using AJaX to submit forms.  When the component was in the webroot, it was very simple, very straightforward.  Now that the components exist outside the webroot, cfajaxproxy is giving me fits.

If all I'm submitting is a single form field value, it works.  If I'm submitting an entire form using jQuery.serializeArray(), suddenly there's a problem.

postData = $('#'+formID).serializeArray();
thisComponent = new ERC(); //Component is in F:\webdocs\_com\public\ERC.cfc and components are mapped in application.cfc
thisComponent.setHTTPmethod('POST');
thisComponent.setCallbackHandler(displayResult);
thisComponent.setErrorHandler(displayFail);
thisComponent.dtsSurvey(postData); // Submit the form to the function "dtsSurvey" in ERC.cfc

This results in the error message mentioned in the subject:  JSON parsing failure: Expected '"' at character 2: '&'

The reason why is because ColdFusion sees: {"form":[{"name"...  (The JSON " are being converted to ASCII.)

How can I fix this?  I've Googled for it, and I'm not finding a solution.

V/r,

    Are we able to see roughly how dtsSurvey function works.

    Assuming the json is correct passing it to that, then something that side maybe changing it.

    Hi, haxtbh,

    The JSON isn't even making it to the function.  In the very beginning of the function, I placed a <CFDUMP var="#form#" /><cfabort> (the function doesn't 'return' anything, it outputs.)  I'm not getting that dump, at all.  The error is being triggered in the cfajax.js because CF can't correctly parse it.  I think CFAJAXPROXY is replacing the quotes, but can't be sure - something is.

    But my onError() is triggering the error email before my CFTRY/CFCATCH can get it, so I'm not being given a file or line number for the error.

    F12 in FireFox Developer Edition is showing that the error is in cfajax.js on multiple lines.

    V/r,

    ^ _ ^

    When you say, "still sends the url or form struct, itself, unchanged, to Portcullis", do you mean without serializeJSON() or HTMLEditFormat() having been called on them? In any case, as you say, canonicalize() should solve the character-entity conversion problem.

    Yup.  I have no idea why the original developer did that, it makes no sense.  But that's what I'm dealing with, even after over two years of him being gone.  And canonicalize() should take care of it, but apparently it isn't.

    Wouldn't it improve the design to save the struct in request scope rather than in session scope?

    Probably.

    Then, chances are, the good man had used xmlFormat().
