$.udb(ds).isLookup()

note

This article is about the isLookup() function of the DataSourceContainer object.

$.udb(ds).isLookup()​

Detects whether the first data source in the container is a lookup data source or not.

Returns a boolean.

Syntax​

$.udb( *ds* ).isLookup()

The required ds is a data source selector.

Example​

// lookup data sources are populated automatically by the framework, so
// skip data sources that turn out to be a lookup when creating new records
let dsc = $.udb('DEPT_LOOKUP');

if (!dsc.isLookup()) {
    dsc.rowCreate();
}
else {
    console.log('%s is a lookup data source; records are not created in it directly', dsc.name());
}
