[Javascript] Arrays

[Bill Marriott]

Hi Everyone,

I am having trouble finding a way to work through a 2 member array and
search for rows that have identical values.

MyArray [0][0] = 2000,  MyArray [0][1] = "t"
MyArray [1][0] = 2000,  MyArray [1][1] = "f"
MyArray [2][0] = 2001,  MyArray [2][1] = "t"
MyArray [3][0] = 2001,  MyArray [3][1] = "t"

I want to find out that rows 3 and 4 in the above array have identical
values.
Does anyone know an easy way?

thanks

Bill Marriott
