How do I remove all attributes from a Javascript object?

For example; if I have the following 'class' how can I perform a reset and remove all its attributes:

function MyObject()
{
   this.type="blah";
   this.name="kkjkj";
}

MyObject.prototype.clearAttribs = function()
{
   // I want to remove name, type etc from 'this'

   // Maybe I can do the following?
   for (var key in this)
      delete this[key];
}

  • Why would you want to do something like this? Commented Apr 13, 2012 at 2:44
  • Do you want to delete only data properties or methods/function properties also? Commented Apr 13, 2012 at 2:51
  • @jfriend00 I dont want to delete prototype functions but if an object has an attribute with a function in it then I want to delete it. For eg; myObj.specFunct = function() {}; then I want to delete that. Commented Apr 13, 2012 at 2:53
  • Then, your current code is fine. Commented Apr 13, 2012 at 2:57

Reset to default

Your code seems fine as is. Since delete will not delete a property from the prototype, you do not even need to use hasOwnProperty.
