在json数组中找到双引号

Question

a json array is as given below

var data = [
            {label:'gggg',data: [[(new Date('2011/12/01')).getTime(),53914],[(new Date('2012/1/02')).getTime(),32172],[(new Date('2012/2/03')).getTime(),824],[(new Date('2012/4/04')).getTime(),838],[(new Date('2012/6/05')).getTime(),755],[(new Date('2012/7/06')).getTime(),0],[(new Date('2012/8/07')).getTime(),0],[(new Date('2012/9/08')).getTime(),0],[(new Date('2012/10/09')).getTime(),0],[(new Date('2012/11/10')).getTime(),0],[(new Date('2012/12/11')).getTime(),0],[(new Date('2012/12/11')).getTime(),0]]}

        ];

in java class for creating the above similar json, i'm using the following code given below.
but the problem is there is a double quotes in each "(new Date(2012/12/01)).getTime()"

can anyone please tell me how to remove those double quotes

 Query q1=session.createQuery("FROM VendorMonth");
          List li1=q1.list();


          String supname="",tempsupname;  
          JSONObject obj = new JSONObject();
          JSONArray jsonarrmast = new JSONArray();
          List s=new ArrayList();

          JSONArray finals=new JSONArray();
          JSONArray finalarray = new JSONArray();
          for(int i=0;i<li1.size();i++)
          {
            HashMap hmap = new HashMap();
            VendorMonth venmonth=(VendorMonth) li1.get(i);
            tempsupname=venmonth.getId().getSupplierName();
            if(i==0){
                supname=venmonth.getId().getSupplierName(); 
            }

            if(!supname.equals(tempsupname)){
                obj.put("label", supname);
                obj.put("data", jsonarrmast); 
                jsonarrmast = new JSONArray();
                s.add(obj);
                finalarray.put(obj);
                obj = new JSONObject();
                supname=venmonth.getId().getSupplierName();

                JSONArray jsonarr = new JSONArray();
                String date=venmonth.getId().getYearnam()+"/"+venmonth.getId().getMonthnam()+"/01";
                String ss=new String("(new Date("+date+")).getTime()");
                jsonarr.put(ss);
                jsonarr.put(venmonth.getId().getRentalrate());
                jsonarrmast.put(jsonarr);
            }
            else
            {
                JSONArray jsonarr = new JSONArray();
                String date=venmonth.getId().getYearnam()+"/"+venmonth.getId().getMonthnam()+"/01";
                String ss=new String("(new Date("+date+")).getTime()");
                jsonarr.put(ss);
                jsonarr.put(venmonth.getId().getRentalrate());
                jsonarrmast.put(jsonarr);

            }

            if(i==(li1.size()-1)){
               obj.put("label", supname);
               obj.put("data", jsonarrmast); 
               jsonarrmast = new JSONArray();
               s.add(obj); 
               finalarray.put(obj);
            }


          }

but i'm getting the output as given below

[{"data":[["(new Date(2012/12/01)).getTime()",10976.23],["(new Date(2013/1/01)).getTime()",51213.8200000002],["(new Date(2013/2/01)).getTime()",32172.31],["(new Date(2013/3/01)).getTime()",824.600000000001],["(new Date(2013/4/01)).getTime()",838.000000000001],["(new Date(2013/5/01)).getTime()",755.780000000001],["(new Date(2013/6/01)).getTime()",50877.12]],"label":"Weather Ford"},{"data":[["(new Date(2012/12/01)).getTime()",24368.3],["(new Date(2013/1/01)).getTime()",1968.76]],"label":"Logan Tools"},{"data":[["(new Date(2012/12/01)).getTime()",3425.63],["(new Date(2013/1/01)).getTime()",731.75]],"label":"Pioneer tools"}]

Answer 1

You're not going to be able to create a JSON object that matches your declaration, because that's not a JSON object: it's Javascript code.

Once that Javascript code is ran, however, data will contain an object that can be serialized to JSON, and I'm assuming that's what you're trying to achieve.

What your Java code does is add a String to a BasicDBArray - the fact that it's interpreted as a String should not come as a surprise. By the same token, when you add an int or a boolean, they're added as ints and booleans, not strings.

What you actuall want to put in your BasicDBArray is the value that new Date('2011/12/01').getTime() would return if interpreted as Javascript: the number of milliseconds between 1970/01/01 and 2011/12/01. I'm assuming you can retrieve that through something like venmonth.getId().getDate().getTime() , or however it is you retrieve a Date instance from your venmonth object.
