Question

I was looking for a way to add new elements to an an existing object like what push does with arrays  I have tried this and it didn t work     var myFunction         Author   my name        date   15-12-2012       doSomething  function            alert  helloworld            myFunction push       bookName  mybook       bookdesc   new      console log myFunction

jQuery syntax mentioned above by Danilo Valente is not working  It should be as following-     extend myFunction       bookName  mybook       bookdesc   new

Just do myFunction foo    bar  and it will add it  myFunction is the name of the object in this case

Use this   myFunction bookName    mybook   myFunction bookdesc    new     Or  if you are using jQuery     myFunction  extend       bookName  mybook       bookdesc   new        The push method is wrong because it belongs to the Array prototype object   To create a named object  try this   var myObj   function        this property    foo       this bar   function            myObj prototype objProp   true  var newObj   new myObj

You could store your JSON inside of an array and then insert the JSON data into the array with push  Check this out https   jsfiddle net cx2rk40e 2     document  ready function          using jQuery just to load function but will work without library        button    on   click   go          Array of JSON we will append too    var jsonTest           colour    blue        link    http1             Appends JSON to array with push  Then displays the data in alert    function go               jsonTest push   colour   red    link   http2           alert JSON stringify jsonTest                      Result of JSON stringify jsonTest      colour   blue   link   http1     colour   red   link   http2      This answer maybe useful to users who wish to emulate a similar result
