localStorage 和 JSON.parse 的问题，错误：Uncaught SyntaxError: Unexpected token [ in JSON at position 1430

Question

I have a problem with JSON.stringify, I'll explain.

I receive from an ajax call the following JSON:

Whenever I receive a similar JSON, I want to do a JSON.stringify (result.responseJSON.eventsTRS) that I add in a variable declared at the top of my JS file "var eventsJSON = ''".

Once the JSON.stringify is done, this is what I get:

then I do a localStorage.setItem ('eventsJSON', eventsJSON) and I get:

Then with my getItem I do a JSON.parse (localStorage.getItem ('eventsJSON')). Out, when I do my parse, I have the following error message: Uncaught SyntaxError: Unexpected token [in JSON at position 1430

Why would you be?

Regards,

Answer 1

I am sorry,

this is my code :

                    for(var i=start ; i<=end;i++ ){
                  $.ajax({
                      dataType: "json",
                      url: "urlServlet",
                      async: false,
                      data: {
                          date: i,
                          action: 'rendementsJourTRS'
                      },
                      sucess: function(data){
                          
                      }, error : function(resultat, statut, erreur){
                          console.log(erreur);
                       }, complete : function(resultat, statut){
                           if(undefined!=resultat.responseJSON.eventsTRS && ''!=resultat.responseJSON.eventsTRS){
                               eventsJSON += JSON.stringify(resultat.responseJSON.eventsTRS);   

                               //Utilisation
                               localStorage.setItem('eventsJSON', eventsJSON);
                           }
                           
                          
                           $('#calendar').fullCalendar('addEventSource', resultat.responseJSON.eventsTRS);
                           
                       }
                  });
            }

For each day, I add a JSON of the day in eventsJSON.

This is my localStorage.getItem('eventsJSON') contents :

Thank you,

Answer 2

The issue is that the string actually contains three array, not one. There are two points in the string (1430 being the first), where there is ][ instead of , Replacing these turns the three arrays into one, which loads as a full array correctly. Thus:

...."title":2}][{"resourceId":"2117....

should be:

...."title":2},{"resourceId":"2117....
