When creating labels off of a feature service's integer data type field, the nulls in field are converted into zeros in the labels.

解决办法

Workaround 1:

Create a new string data type field and use the Field Calculator tool to migrate all of the integer data type values to the new field. In Field Calculator, use str(!IntField!)

Workaround 2:

To maintain the table schema as is, create a new expression in ArcGIS Online:

1. In the web map, navigate to the feature layer's Change Style option.
2. In the Change Style pane, click Add Expression in the drop-down menu.
3. In the Expression window, place the following sample:

function isnull(value){

var val = IsEmpty(value);

if (val) {

return " "

}

else{

return value;

}

}

isnull($feature.IntField)

Note: the $feature.IntField variable in sample is the integer data type field that user would like to base the labels off of (<a href="https://developers.arcgis.com/arcade/function-reference/logical_functions/" target="_blank">https://developers.arcgis.com/arcade/function-reference/logical_functions/</a>).
