Hide a specific date in Portal for ArcGIS and ArcGIS Online Map Viewer pop-ups using an Arcade expression

Summary

In Portal for ArcGIS and ArcGIS Online Map Viewer, it is sometimes necessary to hide a specific date value of a date field in the pop-up of a selected feature. This can be achieved by using the Arcade functions, IIf() and Text().

In this example, the date to be hidden is 1/1/2023. From the attribute table, the date value is only associated with the KLCC Drive line feature.

Procedure

1. Log in to Portal for ArcGIS or ArcGIS Online, and open the web map in Map Viewer.
2. In Map Viewer, on the Settings (light) toolbar, click Configure pop-ups in Portal for ArcGIS, or Pop-ups in ArcGIS Online.
3. In the Pop-ups pane, under Fields list, click Select fields.
4. In the Select fields pane, click Add expression.
5. In the editor, configure the attribute expression.

IIf((Text($feature.<dateField_name>, "M/D/YY") == "<condition_date>"), "<value_if_true>", <value_if_false>)

1. Replace <dateField_name> with the name of the date field.
2. Replace <condition_date> with the value of the date to be hidden.
3. Replace <value_if_true> with the value to be displayed if the date of the selected feature is the same as the specific date to be hidden. In this example, "" is used to return an empty value.
4. Replace <value_if_false> with the value to be displayed if the date of the selected feature is not the specific date to be hidden.

This is the expression used in this example.

IIf((Text($feature.LoggedDate, "M/D/YY") == "1/1/23"), "", $feature.LoggedDate)

6. In the editor, click Done.

The date value for the KLCC Drive line feature equals 1/1/23, so the date is not displayed in the pop-up. Otherwise, the date value in the LoggedDate field is displayed when other line features are selected.
