проблема с localStorage и JSON.parse, ошибка: неперехваченная синтаксическая ошибка: неожиданный токен [в JSON в позиции 1430

#javascript #json #local-storage

#javascript #json #локальное хранилище

Вопрос:

У меня проблема с JSON.stringify, я объясню.

Я получаю от вызова ajax следующий JSON: введите описание изображения здесь

Всякий раз, когда я получаю похожий JSON, я хочу выполнить JSON.stringify (result.responseJSON.eventsTRS), который я добавляю в переменную, объявленную в верхней части моего JS-файла «var eventsJSON = «».

Как только JSON.stringify выполнен, это то, что я получаю: введите описание изображения здесь

затем я делаю localStorage.setItem (‘eventsJSON’, eventsJSON) и получаю: введите описание изображения здесь

Затем с моим GetItem я выполняю JSON.parse (localStorage.GetItem (‘eventsJSON’)). Out, когда я выполняю синтаксический анализ, у меня появляется следующее сообщение об ошибке: Неперехваченная синтаксическая ошибка: неожиданный токен [в JSON на позиции 1430

С чего бы это?

С уважением,

Комментарии:

1. можете ли вы показать позицию 1430 в строке?

2. На самом деле я не думал о том, чтобы посмотреть точно на содержимое моего JSON. У меня в нем 3 массива JSON, потому что в моем коде javascript я перебираю даты (и для 3 дат есть JSON). Для каждого цикла я выполняю eventsJSON = JSON.stringify (result.responseJSON.eventsTRS). eventsJSON объявляется ранее в коде (var eventsJSON = «). Что мне нужно, так это заполнять один и тот же объект JSON каждый раз, когда я его зацикливаю, а не добавлять новый объект JSON. Я не понимаю, как я могу это сделать. У вас есть идея? спасибо, с уважением,

3. Ошибка означает, что строка искажена. Если вы не покажете нам, что находится в позиции 1430, плюс части до и после, чтобы у нас был контекст, никто не сможет точно сказать, в чем проблема. Итак, если вы хотите получить ответ, вы должны показать, что вызывает проблему.

4. ХОРОШО — из этого нового кода, который действительно должен был быть обновлен в вашем вопросе, а не в качестве ответа, я вижу, что проблема в том, что строка содержит ][ дважды. Следовательно, существует три массива. Вам нужно будет заменить их на , перед использованием JSON.parse, чтобы в итоге у вас был только один массив

5. Я только что протестировал это вручную, заменив ][ на , , и данные теперь загружаются полностью как один массив.

Ответ №1:

Прошу прощения,

это мой код :

                     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 amp;amp; ''!=resultat.responseJSON.eventsTRS){
                               eventsJSON  = JSON.stringify(resultat.responseJSON.eventsTRS);   

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

Для каждого дня я добавляю JSON дня в eventsJSON.

Это мое содержимое localStorage.GetItem(‘eventsJSON’) :

Спасибо,

Ответ №2:

Проблема в том, что строка фактически содержит три массива, а не один. В строке есть две точки (1430 является первой), где ][ вместо , замены они превращают три массива в один, который правильно загружается как полный массив. Таким образом:

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

должно быть:

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