[Solved] Creating an OpenLayers function that finds all features with a common attribute

GeorgeStevenJ9272 Asks: Creating an OpenLayers function that finds all features with a common attribute
I’m creating an OpenLayers web application to find the nearest hospitals to a mountain. Some of these hospitals have helipads while others do not. I’m trying to create a function that would respond to a clicked button event which would find the nearest hospitals with a helipad (an attribute of the current hospital field).

Any advice?
