Iterating over every property of an object in javascript using Prototype

Question

Is there a way to iterate over every property of an object using the Prototype JavaScript framework   Here s the situation  I am getting an AJAX response in JSON that looks something like this    foo  1  bar  2  barobj   75  true  76  false  85  true     If I evaluate that json response in to a variable response  I want to be able to iterate over each property in the response barobj object to see which indexes are true and which are false   Prototype has both Object keys   and Object values   but oddly seems to not have a simple Object each   function  I could take the results of Object keys   and Object values   and cross-reference the other as I iterate through one  but that is such a hack that I am sure there is a proper way to do it

You should iterate over the keys and get the values using square brackets   See  How do I enumerate the properties of a javascript object   EDIT  Obviously  this makes the question a duplicate

There s no need for Prototype here  JavaScript has for  in loops  If you re not sure that no one messed with Object prototype  check hasOwnProperty   as well  ie  for var prop in obj        if obj hasOwnProperty prop           doSomethingWith obj prop

You have to first convert your object literal to a Prototype Hash      Store your object literal var obj    foo  1  bar  2  barobj   75  true  76  false  85  true       Iterate like so   The  H   construct creates a prototype-extended Hash   H obj  each function pair     alert pair key     alert pair value
