Error syntaxerror unexpected token n in json at position 0

It' s unlikely that API has the only route which is mounted at root and available as. The reason for the error is that JSON. parse( ) expects a String value and products is an Array. Later I found this to be an issue with the new line operator [ \ n], inside a field value. One other gotcha that can result in " SyntaxError: Unexpected token" exception when calling JSON. charCodeAt( x) ; if( c > = 0 & & c < = 31) { throw ' problematic character found at position ' + x; } } }. ajax( { url: ' listing_ manage_ save. php' method: ' post', dataType: ' json', / / dataに FormDataを指定 data: formData, / / Ajaxがdataを整形しない指定 processData: false, / / contentTypeもfalseに指定 contentType: false } ). json で受け取ろう. You have a strange char at the beginning of the file. charCodeAt( 0) = = = 65279. I would recommend: fs. readFile( ' addresses.

    Unexpected json syntaxerror

    json', function ( err, data) { if ( data) { console. log( " Read JSON file: " + data) ; data = data. trim( ) ; / / or. Hi I am getting this error using angularjs through the chrome console:. Specifically, SyntaxError: Unexpected token N is often the result of accidentally returning a NaN in your JSON, although it. The key is to ensure that you' re properly sanitizing your outputs on the server, and substituting a zero for any NaN values, or wrapping in quotes, etc. Notice: Undefined index: project_ id in / var/ www/ html/. ECMA- 404 The JSON Data Interchange Standard says: A string is a sequence of zero or more Unicode characters, wrapped in double quotes. In your case you have single quoutes. So you can use str. replace( " ' ", " " " ) ;.

    The wording of the error message corresponds to what you get from Google Chrome when you run JSON. parse( ' ' ) ; / / Uncaught SyntaxError: Unexpected token < in JSON at position 0 / / at JSON. i know that there' s so many questions about this but sorry im really confuse about this error. i created a login page and i used ajax for the POST Request. what happens is when i used this $. / ajax/ checklogin. php', type: ' POST',.
