Navigator is a bit more complicated unfortunately, since there's no equivalent to innerText.
It's a pain but it works. To use this directory, fill in as much of the information as you'd like and click on the 'Find' button. It will respond by listing all District employees who match the information you specify. If you enter 'J' for the first name and 'Smith' for the last name, select 'Central Services' for the building, then hit 'Find', it will list all 'J. Smith's that work at Central Services. If you select 'substitute teacher' for the job description, then hit 'Find', it will list all substitute teachers in the Sioux Falls School District.
