Inserting a return BEFORE a specific character

[olllllllo]

I am looking for a way to do the following in JavaScript.

 

The client list provided has a column header of "DROPOFLOCATION" and the column's cells contain a child and sibling name contained in parentheses.

Example:

Dropofflocation

1089 E 77TH ST  (Child Name + Sibling Name)

7618 ABERDEEN AVE  (Child Name)

 

I am looking for a way to insert a paragraph return before the first parentheses, so (Child Name + Sibling Name) returns to the line below. This is how I would like it to appear.

 

1089 E 77TH ST

(Name one +  Sibling Name)

 

Any ideas on how to code this?

My coworker came up with this solution:

 

if (Field("DROPOFFLOCATION").indexOf("(") > -1)

{

   return ReplaceSubstring(Field("DROPOFFLOCATION"),"(","<br>(");

}

 

return Field("DROPOFFLOCATION");
