If you want to easily view the contents of objects while debugging  install a tool like Firebug and use console log   console log product     If you want to view the properties of the object itself  don t alert the object  but its properties   alert product ProductName   alert product UnitPrice      etc     or combine them    As said  if you really want to boost your JavaScript debugging  use Firefox with the Firebug addon  You will wonder how you ever debugged your code before

you can use the JSON stringify   method found in modern browsers and provided by json2 js   var myObj     myProp   Hello    alert  JSON stringify myObj          alerts   myProp   Hello      or   also check this library   http   devpro it JSON files JSON-js html

You should really use Firebug or Webkit s console for debugging  Then you can just do console debug product   and examine the object

Use Javascript native JSON stringify method  To visualise it in a nicer way  you can use  like  JSON stringify obj null  4    x000D   x000D  var obj    data    empmenuid   1   empid  null  deptid   66   aliasid   66   firstname   66   lastname   66   sin   66   status   66   empclass   66   hiredate   66   seneoritydate   66   separationdate   66     empmenuid   3   empid  null  deptid   12   aliasid   12   firstname   12   lastname   12   sin   12   status   12   empclass   12   hiredate   12   seneoritydate   12   separationdate   12   recalldate   12   martialstatus   12   gender   12   pager   12   locid   12   jobtitle   12   jobtitlestart   12   fullpart   12   manager   12   managername   12   middlename   12   nickname   12   paytype   12   payfreq   12     x000D  recordType    object    x000D   x000D  alert JSON stringify obj null  4    x000D   x000D   x000D

alert  JSON stringify product

Depending on which property you are interested in   alert product ProductName   alert product UnitPrice   alert product Stock

User · Answer

alert  product UnitName         product UnitPrice         product Stock    or else create a toString   method on your object and call  alert product toString      But I have to agree with other posters - if it is debugging you re going for then firebug or F12 on IE9 or chrome and using console log is the way to go

This is what I use   var result       for  var l in someObject     if  someObject hasOwnProperty l       result push l      someObject l          alert result join   n       If you want to show nested objects too  you could use something recursive   function alertObject obj    var result        function traverse obj    for  var l in obj      if  obj hasOwnProperty l         if  obj l  instanceof Object          result push l    gt  object            traverse obj l           else          result push l      obj l                        traverse obj    return result
