Split and rearrange text strings within a pop-up using Arcade expressions in ArcGIS Online and Portal for ArcGIS Map Viewer

Summary

In ArcGIS Online and Portal for ArcGIS Map Viewer, Arcade expressions with multiple statements can be used to split and reposition text strings of a field within a pop-up. The repositioned text strings can be used for data management or search results optimization. This article provides an example and instructions using Arcade expressions to split and rearrange text strings within a pop-up for Map Viewer.

The image below shows a Map Viewer pop-up with the Forest_Name field and the text string records.

Procedure

1. Open the map in Map Viewer. Click Layers on the Contents (dark) toolbar, and select the layer with the pop-up for editing.
2. On the Settings (light) toolbar, click Pop-ups > Options > Attribute expressions.
3. Click + Add expression to open the Arcade expression editor window.
4. In the editor window, specify a name for the new expression.
5. In the Expression dialog box, insert the following Arcade expression.
   1. Define the variable with the function to split the text string and the blank space as a separator.

var <variableName1> = Split($feature.<featureName>, ' ')

2. Define the variable with the function to count the number of splits for each record.

var <variableName2> = Count(<variableName1>)

3. Specify the following statement to return a blank value when the field value is empty.

if (<variableName2> == 0) {
  return ''
}

4. Specify the following statement to return the same text value when the field is a single word.

if (<variableName2> == 1) {
  return $feature.<featureName>
}

5. Specify the following statement to rearrange the position of the second word to the first position when the field has two words.

if (<variableName2> == 2) {
  return <variableName1>[1] + ' ' + <variableName1>[0]
}

6. Specify the following statement to rearrange the position of the first word to the third position when the field has three words.

if (<variableName2> == 3) {
  return <variableName1>[1] + ' ' + <variableName1>[2] + ' ' + <variableName1>[0]
}

The code block below is an example of the full working expression.

var arrName = Split($feature.Forest_Name, ' ')
var lenName = Count(arrName)
if (lenName == 0) {
  return ''
}
if (lenName == 1) {
  return $feature.Forest_Name
}
if (lenName == 2) {
  return arrName[1] + ' ' + arrName[0]
}
if (lenName == 3) {
  return arrName[1] + ' ' + arrName[2] + ' ' + arrName[0]
}

6. Click Run to view a preview of the expression result. If the required result is achieved, click Done.

7. Click the Previous button above the Arcade expression in the Pop-up expressions pane.

8. Click Fields list to expand the list of fields displayed in the pop-ups, and click Select fields.
9. Check the expression field under the Expressions section, and click Done.
