Access Sub box on a web page with Javascript

I have in the past been able to use AppleScript to get data from the web but recently ran into an issue that I thought I could solve using JavaScript with in AppleScript. I know very little about Javascript and what I have used is from ideas I have found on the web

The following script opens the 1st box using its ID. However I cannot find an ID for the next box within that 1st box.

my SelectLoc(("main-filter-button"))

to SelectLoc(LocID)
	tell application "Safari"
		do JavaScript "document.getElementById('" & LocID & "').click();" in document 1
	end tell
end SelectLoc

I can find numerous instances of a class and the one I need to use is

Tried using the actual name of the field as in the following, as just using the name does not work I assume I need to somehow concatenate the class description, but how?

set NameLoc to " Ex-div Date"

set Namenum to 0
clickClassName(NameLoc, Namenum)
to clickClassName(NameLoc, Namenum)	
	tell application "Safari"		
		do JavaScript "document.getElementsByClassName('" & NameLoc & "')[" & Namenum & "].click();" in document 1		
	end tell	
end clickClassName
