Replace multiple text in a single string using Arcade in ArcGIS Online Map Viewer

Summary

In ArcGIS Online Map Viewer, descriptive details of features within a map are displayed through pop-ups. Pop-ups can display attachments, charts, images, texts, and links to external web pages. In some cases, the pop-up display includes special character strings in each field and these characters must be replaced. The task of replacing these fields is simpler with Arcade expressions.

This article provides instructions to replace multiple text or special characters in a single string using Arcade expressions in ArcGIS Online Map Viewer.

Procedure

1. Open the map in Map Viewer. Click Layers, and select the <layer name> with the pop-up for editing.

2. Click Configure pop-ups > Manage expressions.

3. Click + Add expression to open the Arcade Expression dialog box.

4. Configure the Arcade expression using the variables assigned with the Replace() function to identify the multiple text or characters, and replace them with the desired text in the field. The sample Arcade expression below replaces the special characters or symbols in the Notes field of the feature layer.

var str=Replace($feature.Notes, '&', 'and') //Replace & to spell and
var str1=Replace(str, '#', 'No.') // Replace # with the word No. 
var str2=Replace(str1, '\ ', ' ') // Replace \ with a blank space
Replace(str2, '/', ' ') // Final replacement to return the result

5. Rename the expression. In this example, the expression is named Notes to match the selected field name. Click OK.

6. Click the previous button to return to the Pop-ups pane.

7. Click Fields list to expand the list of fields currently displayed in the pop-ups, and click Select fields.

8. Uncheck the Notes field without the Arcade expression, and check the Notes field with the Arcade expression. Click Done.
