Get object from one of its values

Show all headers | View raw

If there are one or more objects each of which has a property called 
childArray whose value is always a one dimensional array and elements of 
the array are unique (ie an element cannot also occur in the childArray 
of another object) then if I know the value of one element of a 
childArray how do I find the object it's associated with?

For example if I have:

var a = {};
     a.childArray = [1,2,3,a,b,c,..];
var b = {};
     b.childArray = [4,5,6,d,e,f,...];
var c = {};
     c.childArray = [7,8,9,g,h,i,...];
...

and I'm given the value "5" how do I find that it's associated with "b"?

The code is dynamically created so I don't know beforehand what or how 
many objects will be created.
