How to JSON decode array elements in JavaScript

Question

I have a JavaScript array that  among others  contains a URL  If I try to simply put the URL in the page  the array is in a project involving the Yahoo  Maps API  it shows the URL as it should be   But if I try to do a redirect or simply do an  alert  on the link array element I get       function   return JSON encode this      As far as I see it this is because the browser does an JSON encode when it renders the page  thus the link is displayed OK  I have tried several methods to make it redirect  that s what I want to do with the link  correctly  including the usage of  eval   but with no luck   After following some suggestions I ve run eval       jsonObject        but it still returns the same output   So how s this done

If you get this text in an alert   function   return JSON encode this      when you try alert myArray i    then there are a few possibilities    myArray i  is a function  most likely  myArray i  is the literal string  function   return JSON encode this     myArray i  has a  toString   method that returns that function or that string  This is the least likely of the three    The simplest way to tell would be to check typeof myArray i
