FAQ Topic - How do I access a property of an object using
a string?
-----------------------------------------------------------------------
There are two ways to access properties: dot notation and square bracket
notation. What you are looking for is the square bracket notation in
which the dot, and the identifier to its right, are replaced with a set
of square brackets containing a string. The value of the string matches
the identifier. For example:-
//dot notation
var bodyElement = document.body;
//square bracket notation, using an expression
var bodyElement = document["bo"+"dy"];
