FieldInfoFormat | API Reference | ArcGIS Maps SDK for JavaScript 4.31

The FieldInfoFormat class is used with numerical or date fields to provide more detail about how the value should be displayed in a popup. Use this class in place of the legacy formatting functions: DateString, DateFormat, and/or NumberFormat.

When formatting Number fields, you must set both the digitSeparator and places properties for the formatting to take effect.

Example

let fieldInfo = new FieldInfo({
  fieldName: "PROMINENCE_ft",
  label: "Prominence (feet)",
  //autocasts to FieldInfo.Format
  format: {
    places: 0,
    digitSeparator: true
  }
};

The time-only date fields will only honor the time component (i.e. ShortTime, ShortTime24, LongTime or LongTime24) in a dateFormat. Date formats without a time component are not supported by time-only fields.
Starting with version 4.28, date fields are formatted using the short-date-short-time format rather than long-month-day-year in popup templates created with the createPopupTemplate() method. This is also the case for default popup templates created by setting the defaultPopupTemplateEnabled property to true on the Popup, Features, or Feature widgets. For example, previously a date that may have appeared as "December 30, 1997" will now appear as "12/30/1997 6:00 PM". fields that need to have number formatting for chart/text elements.
If displaying a timestamp-offset or date type field in a Popup, Features, or Feature widget and the MapView has a timezone set other than unknown, the abbreviated time zone suffix will be omitted from the attribute value. For example, the attribute value will display as 9/28/2014, 7:58 PM. To display an abbreviated time zone suffix, see the Read more section.

If the user wants date fields to show a time zone suffix (e.g. 9/28/2014, 7:58 PM PST), then the Arcade Text function can be used to format the field value. This can be done either with ExpressionContent or attribute expressions.

// Attribute expression using expressionInfos to append the time zone suffix to a date field.
// Date field types will show in the MapView's current time zone.
layer.popupTemplate = {
  title: "Display time zones",
  fieldInfos: [{
    fieldName: "expression/date-with-time-zone-suffix",
  }],
  expressionInfos: [{
    expression: `Text($feature.date_Field, "M/D/Y, h:mm A ZZZZ")`,
    name: "date-with-time-zone-suffix",
  }],
  content: [{
    type: "fields"
  }]
};

// ExpressionContent to append the time zone suffix to a date field.
// Date field types will show in the MapView's current time zone by default.
layer.popupTemplate = {
  title: "Display time zones",
  content: [{
    type: "expression",
    expressionInfo: {
      expression: `return {
        type : 'text',
        text : Text($feature.date_Field, "M/D/Y, h:mm A ZZZZ")
      }`
    }
  }]
 };

If the user wants timestamp-offset fields to display in the time zone from the server with an abbreviated time zone suffix, then the Arcade Text function can be used to format the field value. This can be done either with ExpressionContent or attribute expressions.

// Attribute expression using expressionInfos to append the time zone suffix to a timestamp-offset field.
layer.popupTemplate = {
  title: "Display time zones",
  fieldInfos: [{
    fieldName: "expression/TSO-from-server",
  }],
  expressionInfos: [{
    expression: `Text($feature.TimestampOffset_Field, "M/D/Y, h:mm A ZZZZ")`,
    name: "TSO-from-server",
  }],
  content: [{
    type: "fields"
  }]
};

// ExpressionContent to append the time zone suffix to a timestamp-offset field.
layer.popupTemplate = {
  title: "Display time zones",
  content: [{
    type: "expression",
    expressionInfo: {
      expression: `return {
        type : 'text',
        text : Text($feature.TimestampOffset_Field, "M/D/Y, h:mm A ZZZZ")
      }`
    }
  }]
 };

If the user wants timestamp-offset fields to display in the MapView's time zone with an abbreviated time zone suffix, then the ChangeTimeZone Arcade function can be used to format the value.

// Attribute expression using expressionInfos to append the MapView's current time zone suffix to a timestamp-offset field
layer.popupTemplate = {
  title: "Display time zones",
  fieldInfos: [{
    fieldName: "expression/TSO-matching-view-tz",
  }],
  expressionInfos: [{
    expression: `Text(ChangeTimeZone($feature.TimestampOffset_Field, GetEnvironment().timeZone), "M/D/Y, h:mm A ZZZZ")`,
    name: "TSO-matching-view-tz",
  }],
  content: [{
    type: "fields"
  }]
};

// ExpressionContent to append the MapView's current time zone suffix to a timestamp-offset field
layer.popupTemplate = {
  title: "Display time zones",
  content: [{
    type: "expression",
    expressionInfo: {
      expression: `return {
        type: "text",
        text: Text(ChangeTimeZone($feature.TimestampOffset_Field, GetEnvironment().timeZone), "M/D/Y, h:mm A ZZZZ")
      }`
    }
  }]
};
