(JavaScript) JSON Date Parsing
Demonstrates how to parse date/time strings from JSON.
Note: This example uses the DtOf and DateOf methods introduced in Chilkat v9.5.0.73
var success = false;
var json = new CkJsonObject();
json.EmitCompact = false;
// First, let's create JSON containing some date/time strings.
json.UpdateString("test.timestamp","2018-01-30T20:35:00Z");
json.UpdateString("test.rfc822","Tue, 24 Apr 2018 08:47:03 -0500");
json.UpdateString("test.dateStrings[0]","2018-01-30T20:35:00Z");
json.UpdateString("test.dateStrings[1]","Tue, 24 Apr 2018 08:47:03 -0500");
json.UpdateNumber("test.StartLoggingTime","1446834998.695");
json.UpdateNumber("test.Expiration","1442877512.0");
json.UpdateInt("test.StartTime",1518867432);
console.log(json.Emit());
// We've built the following JSON:
// {
// "test": {
// "timestamp": "2018-01-30T20:35:00Z",
// "rfc822": "Tue, 24 Apr 2018 08:47:03 -0500",
// "dateStrings": [
// "2018-01-30T20:35:00Z",
// "Tue, 24 Apr 2018 08:47:03 -0500"
// ],
// "StartLoggingTime": 1446834998.695,
// "Expiration": 1442877512.0,
// "StartTime": 1518867432
// }
// }
// Use the DateOf and DtOf methods to load Chilkat date/time objects with the date/time values.
// The CkDateTime object is primarily for loading a date/time from numerous formats, and then getting
// the date/time in various formats. Thus, it's primarly for date/time format conversion.
// The DtObj object holds a date/time where the individual components (day, month, year, hour, minutes, etc.) are
// immediately accessible as integers.
var dateTime = new CkDateTime();
var dt = new CkDtObj();
var getAsLocal = false;
// Load the date/time at test.timestamp into the dateTime object.
success = json.DateOf("test.timestamp",dateTime);
console.log(dateTime.GetAsTimestamp(getAsLocal));
console.log(dateTime.GetAsUnixTime(false));
console.log(dateTime.GetAsRfc822(getAsLocal));
success = json.DateOf("test.rfc822",dateTime);
console.log(dateTime.GetAsTimestamp(getAsLocal));
json.I = 0;
success = json.DateOf("test.dateStrings[i]",dateTime);
console.log(dateTime.GetAsTimestamp(getAsLocal));
json.I = 1;
success = json.DateOf("test.dateStrings[i]",dateTime);
console.log(dateTime.GetAsTimestamp(getAsLocal));
success = json.DateOf("test.StartLoggingTime",dateTime);
console.log(dateTime.GetAsTimestamp(getAsLocal));
success = json.DateOf("test.Expiration",dateTime);
console.log(dateTime.GetAsTimestamp(getAsLocal));
success = json.DateOf("test.StartTime",dateTime);
console.log(dateTime.GetAsTimestamp(getAsLocal));
// Output so far:
// 2018-01-30T20:35:00Z
// 1517344500
// Tue, 30 Jan 2018 20:35:00 GMT
// 2018-04-24T13:47:03Z
// 2018-01-30T20:35:00Z
// 2018-04-24T13:47:03Z
// 2015-11-07T00:36:38Z
// 2015-09-22T04:18:32Z
// 2018-02-17T17:37:12Z
// Now load the date/time strings into the dt object:
success = json.DtOf("test.timestamp",getAsLocal,dt);
console.log("month=" + dt.Month + ", day=" + dt.Day + ", year=" + dt.Year + ", hour=" + dt.Hour + ", minute=" + dt.Minute);
success = json.DtOf("test.rfc822",getAsLocal,dt);
console.log("month=" + dt.Month + ", day=" + dt.Day + ", year=" + dt.Year + ", hour=" + dt.Hour + ", minute=" + dt.Minute);
json.I = 0;
success = json.DtOf("test.dateStrings[i]",getAsLocal,dt);
console.log("month=" + dt.Month + ", day=" + dt.Day + ", year=" + dt.Year + ", hour=" + dt.Hour + ", minute=" + dt.Minute);
json.I = 1;
success = json.DtOf("test.dateStrings[i]",getAsLocal,dt);
console.log("month=" + dt.Month + ", day=" + dt.Day + ", year=" + dt.Year + ", hour=" + dt.Hour + ", minute=" + dt.Minute);
success = json.DtOf("test.StartLoggingTime",getAsLocal,dt);
console.log("month=" + dt.Month + ", day=" + dt.Day + ", year=" + dt.Year + ", hour=" + dt.Hour + ", minute=" + dt.Minute);
success = json.DtOf("test.Expiration",getAsLocal,dt);
console.log("month=" + dt.Month + ", day=" + dt.Day + ", year=" + dt.Year + ", hour=" + dt.Hour + ", minute=" + dt.Minute);
success = json.DtOf("test.StartTime",getAsLocal,dt);
console.log("month=" + dt.Month + ", day=" + dt.Day + ", year=" + dt.Year + ", hour=" + dt.Hour + ", minute=" + dt.Minute);
// Output:
// month=1, day=30, year=2018, hour=20, minute=35
// month=4, day=24, year=2018, hour=13, minute=47
// month=1, day=30, year=2018, hour=20, minute=35
// month=4, day=24, year=2018, hour=13, minute=47
// month=11, day=6, year=2015, hour=18, minute=36
// month=9, day=21, year=2015, hour=23, minute=18
// month=2, day=17, year=2018, hour=11, minute=37
