I set the dataType to 'text' because I don't want to Jquery parse my JSON automatically. My code is the following:
var membId = '5';
$('#submitNewDescription').live('click',function(){
//An ajax request is made to update the DB
$.ajax({
url: '../../cgi-bin/qualification.py',
type: 'POST',
data: ({newDescription:$('#newDescription').val(),id:membId}),
dataType: 'text',
cache: 'false',
success: function(data){
json = JSON.parse(data);
console.log(data);
console.log(json);
}
});
});
And it returns that string: {"error":["ORA-01031 insufficient privileges"]} in both console.log commands. It means that the parse isn't working since it doesn't return a JavaScript object. JSONLint says to me that is a valid JSON.
Anyone has an idea of what is happening?
EDIT
I can set to 'json', it is not problem. The problem is that JSON.parse and $.parseJSON should work. Since they are not, I changed 'dataType' to 'json', but the same string is returned. I have no idea what is happening.

The "SyntaxError: JSON. parse: unexpected character" error occurs when passing a value that is not a valid JSON string to the JSON. parse method, e.g. a native JavaScript object. To solve the error, make sure to only pass valid JSON strings to the JSON.
JSON. parse() parses a string as JSON. This string has to be valid JSON and will throw this error if incorrect syntax was encountered.
A function that does not accept a callback or return a promise blocks until it returns a value. So yes it JSON. parse blocks. Parsing JSON is a CPU intensive task, and JS is single threaded.
If you need to parse a JSON string that returns a dictionary, then you can use the json. loads() method. If you need to parse a JSON file that returns a dictionary, then you can use the json. load() method.
Probably because you're looking for $.parseJSON instead? Also I beieve jQuery will look at the data and make a best-guess at parsing it before passing it off to the callback. So, if it looks like JSON chances are jQuery's already giving you a JavaScript object back which then can't be re-parsed using JSON.parse/$.parseJSON.
You can also change your dataType field to 'json' and let jQuery do it for you...

change dataType: 'text' to dataType: "json" and also JSON.parse to $.parseJSON
