данные диаграммы Google форматирования ошибка (JavaScript)

Question

Я звоню график рассеяния с google.visualization.arrayToDataTable(loadGraphData); где loadGraphData генерируется из бэк-бобов в виде ArrayList<ArrayList<String>> и выглядит следующим образом:

"[['Date','Variable'], [0, 9.66], [1, 9.24], [2, 8.73], [3, 8.50]...]" 

данные не загружает граф с помощью var, но если я вставляю результат на свое место (без кавычек), код работает и корректно отображает данные. есть ли удобный способ удалить цитаты, или я использую неправильный подход?

BTW, я заменил даты на 0,1 ... поскольку это вызывало другую ошибку, которую я еще не исправить.

данные поступают из JSF основы фасоли, экстракт ниже:

public ArrayList graphData(int variable, int nodeNumber) 
    { 
    Collection dataValues = dataValuesFacade.findVariable(currentNodes.getCurrentNodes().get(nodeNumber), variable); 
    ArrayList <DataValues> dataValuesArray = new ArrayList(); 
    dataValuesArray.addAll(dataValues); 
    dataValues = dataValuesFacade.findVariable(currentNodes.getCurrentNodes().get(nodeNumber), 0); 
    ArrayList<DataValues> timeValuesArray = new ArrayList(); 
    timeValuesArray.addAll(dataValues); 
    ArrayList <DataPairs> dataPairs = new ArrayList(); 
    dataPairs.add(new DataPairs()); 
    ArrayList<ArrayList<String>> returnData = new ArrayList<>(); 
    ArrayList<String> newAL = new ArrayList(); 
    newAL.add("Date"); 
    newAL.add("Variable"); 
    returnData.add(newAL); 
    //Gson gson = new Gson(); 

    for (int i=0;i<dataValuesArray.size();i++) 
    { 

     String varTimestamp = dataValuesArray.get(i).getdTimeStamp().toString(); 
     String dateTimestamp = timeValuesArray.get(i).getdTimeStamp().toString(); 
     String tempVariable = dataValuesArray.get(i).getdVariable().toString(); 
     String tempDate = timeValuesArray.get(i).getdVariable().toString(); 


     if ((varTimestamp.equals(dateTimestamp))& 
       (dataPairs.get(i).getXdateStamp()==null)& 
       (dataPairs.get(i).getYvariable()==null)& 
       (dataPairs.get(i).getTimeStamp()==null)) 
     { 
      dataPairs.get(i).setTimeStamp(dateTimestamp); 
      dataPairs.get(i).setYvariable(tempVariable); 
      dataPairs.get(i).setXdateStamp(tempDate); 
      ArrayList<String> tempAL = new ArrayList(); 
      tempAL.add(i+""); 
      tempAL.add(tempVariable); 
      returnData.add(tempAL); 
      dataPairs.add(new DataPairs()); 
     } 
    } 
    //String rt = gson.toJson(returnData); 
    return returnData; 
} 

Это грязно, но я пытался все виды решений, которые нуждаются в очистке до.

точный выход следующим образом:

Answer 1

Это не работает, потому что функция член arrayToDataTable() ожидает массив в качестве аргумента, и вы передаете строку.

Один из вариантов, который может работать, - это сначала разобрать данные, передаваемые вам как JSON. Единственное беспокойство - обмотка с одинарными кавычками Date и Variable. Одиночные кавычки недействительны JSON. Если вы в состоянии изменить ответ, вы можете просто сделать это:

google.visualization.arrayToDataTable(JSON.parse(loadGraphData));

В противном случае, если вам придется иметь дело с одинарными кавычками, вы можете заменить их в двойных кавычках, то разобрать, как JSON:

google.visualization.arrayToDataTable(JSON.parse(loadGraphData.replace(/'/g, '"'));
