javascript - cannot create object in IE using new Keyword -

var com = {}; var com.project = function(){    this.display = function(){    alert("hai.....");    } } var project_obj = new com.project(); 

while creating project_obj got error in ie9 "object doesn't support action"

this code working in firefox , chrome. have given sample code. i'm trying use classes , package concept in javastript.

i don't know why error came in ie.
