Javascript: test if an object is an array.

[Tribo]

Hi! I would like to know if there is an elegant way to test if an object is an array.

Example:

function ProcessObject(object) {
  //Test if it is an array.
  if(...) {
    for(int i=0; i < object.length; i++) {
      //object[i] ...
    }
  }
  else {
    //Don't process as an array.
    //object.value  ...
  }
}

In the code above, the function is receiving an object that could be an array or not. The main reason I want to know if it is an array is because I want to use the length property. Do anyone know if there is a property in DOM to know if an object is an array so I can invoke the length property without error?

Thanks a lot!

PS: I make it, in a not elegant way...
