Date : October 14 2020, 02:23 PM
I wish this help you I'm just looking for the best practice to remove remove all objects from json data which contains a specific term/keyword. , You can simply use Array.filter():
code :
var arr = [{ "name":"John", "age":30, "cars":"BMW" }, { "name":"Micheal", "age":30, "cars":"Ford,BMW" }, { "name":"Andy", "age":29, "cars":"Ford" }, { "name":"Andy", "age":29, "cars":"Ford,Toyota" }];

var result = arr.filter(({cars})=> !cars.includes("BMW"));

console.log(result);

Remove JSON objects which have specific field type from JSON array field in MongoDB document


By : hunter colgate
Date : March 29 2020, 07:55 AM
I hope this helps you . Given a collection with documents which have an array field containing JSON objects (key-value pairs) e.g.: , I suppose you are looking to remove data from an array like this:
code :
{ 
    "field" : "aaa", 
    "list" : [  "aaa",  NumberLong(123),  "bbb",  NumberLong(456) ] 
}
 db.collection.update({ },{ "$pull": { "list": {"$type": 18 } } })
{ 
    "list" : [
        { "key" : "val" }, 
        { "key" : NumberLong(100) },
        { "key" : NumberLong(123) } 
    ] 
}
 db.list.update({ }, { "$pull": { "list": { "key": {"$type": 18  } } } })

How to remove special characters from JSON stream, so that I can use gson API to convert JSON objects to JAVA objects?


By : Michael Leroux
Date : March 29 2020, 07:55 AM
wish help you to fix your issue It works perfectly as expected. There is no need to remove these special characters from JSON stream to convert it into Java object.
Please have a look at below sample code:
code :
BufferedReader reader = new BufferedReader(new FileReader(new File("json.txt")));
MyJSONObject data = new Gson().fromJson(reader, MyJSONObject.class);
System.out.println(new GsonBuilder().setPrettyPrinting().create().toJson(data));

class MyJSONObject {
    private String color;
    private String imageUrl;
    private String styleId;
    private String originalPrice;
    private String price;
    private String productUrl;
    private String percentOff;
    // getter & setter
}
{
  "color": "Arctic White",
  "styleId": "1788212",
  "originalPrice": "$64.95",
  "price": "$64.95",
  "percentOff": "0%"
}
BufferedReader reader = new BufferedReader(new FileReader(new File("resources/json29.txt")));

class MyJSONObject {
    private String color;
    private String imageUrl;
    private String styleId;
    private double originalPrice;
    private double price;
    private String productUrl;
    private double percentOff;
    // getter & setter
}

class MyJSONObjectDeserializer implements JsonDeserializer<MyJSONObject> {

    @Override
    public MyJSONObject deserialize(final JsonElement json, final Type typeOfT,
            final JsonDeserializationContext context) throws JsonParseException {

        JsonObject jsonObject = json.getAsJsonObject();

        MyJSONObject myJSONObject = new MyJSONObject();
        myJSONObject.setColor(jsonObject.get("color").getAsString());
        myJSONObject.setImageUrl(jsonObject.get("imageUrl").getAsString());
        myJSONObject.setStyleId(jsonObject.get("styleId").getAsString());
        myJSONObject.setProductUrl(jsonObject.get("productUrl").getAsString());

        try {
            String price = jsonObject.get("price").getAsString();
            String originalPrice = jsonObject.get("originalPrice").getAsString();
            String percentOff = jsonObject.get("percentOff").getAsString();

            myJSONObject.setPrice(Double.valueOf(price.substring(1)));
            myJSONObject.setOriginalPrice(Double.valueOf(originalPrice.substring(1)));
            myJSONObject.setPercentOff(Double.valueOf(percentOff.substring(0,
                    percentOff.length() - 1)));

        } catch (NumberFormatException e) {
            e.printStackTrace();
        }

        return myJSONObject;
    }
}

MyJSONObject data = new GsonBuilder()
        .registerTypeAdapter(MyJSONObject.class, new MyJSONObjectDeserializer()).create()
        .fromJson(reader, MyJSONObject.class);

System.out.println(new GsonBuilder().setPrettyPrinting().create().toJson(data));

How to exclude specific JSON objects when rendering data


By : Glennan Carnie
Date : March 29 2020, 07:55 AM
will be helpful for those in need Converted your example to a stack-snippet and all it took was a filter, the values that map wasn't returning were undefined objects in your dataset and were causing the issue.
code :
var admissData = {
  "d": {
    "results": [{
        "p_h_v": "Maybe", // ---------- meets conditions---this obj rendered
        "partc": "show this too"
      },
      {
        "p_h_v": "", // ------------ this doesn't meet conditions, isn't rendered
        "partc": "test - no show"
      },
      {
        "p_h_v": "Yes", // ---------- meets conditions---this obj rendered
        "partc": "test - show"
      }
    ]
  }
};

function loadProHac() {
  let admissText = admissData.d.results
    .filter(x => x.p_h_v !== "")  //added your filter here.
    .map(function(val) {
      return {
        "PHV": val.p_h_v,
        "Part C": val.partc
      }
    });

  $('#prohac-table').DataTable({
    data: admissText,
    columns: [{
        data: "PHV"
      },
      {
        data: "Part C"
      }
    ]
  });
}
loadProHac();

Need to remove specific objects having a specific pattern in keys from an array of objects in javascript


By : Senthil
Date : March 29 2020, 07:55 AM
Hope that helps The function indexOf(pattern) will tell you if a string contains the pattern provided. Also, in javascript, you can iterate an object using a for loop. So coupling that together we can do the following:
