You can do this to traverse the tree and keep track of how deep you are to figure out dot notation property names: import com.fasterxml.jackson.databind.JsonNode; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.databind.node.ArrayNode; import com.fasterxml.jackson.databind.node.ObjectNode; import com.fasterxml.jackson.databind.node.ValueNode; import java.io.IOException; import java.util.HashMap; import java.util.Iterator; import java.util.Map; import org.junit.Test; public class FlattenJson { String json = “{\n” + ” \”Port\”:\n” + … Read more
This is an issue in node which is caused by white space in your windows username (possibly between the first-name and last-name in windows). run the following command after replacing firstname with your windows user firstname in command prompt with administrator access npm config set cache “C:\Users\Firstname~1\AppData\Roaming\npm-cache” –global
Its too late, but it may be simple and useful var json = { “key1” : “watevr1”, “key2” : “watevr2”, “key3” : “watevr3” }; var keytoFind = “key2”; var index = Object.keys(json).indexOf(keytoFind); alert(index);
You can create daily,monthly and yearly data by using the same logic. You just have to replace Hour with Day,Month or Year. List<dynamic> dailyData = new List<dynamic>(); DateTime dayIterator = StartDate.Value; while (dayIterator.Hour <= ddvm.CurrentDay) { if (ddvm.DailyPaymentTotal != null && ddvm.DailyPaymentTotal.Count() > 0 ) { DailyPaymentTotalModel day = ddvm.DailyPaymentTotal.FirstOrDefault(hpt => hpt.DateTimeStamp == dayIterator); if … Read more
