Array

Note that Array is a builtin JavaScript object.

The methods listed below are merely prototype extensions to it.

Object Summary

 

Prototype add-ons to the builtin Array object.

Currently, only basic methods are included in it.

We're planning to make new additions to the object in latter releases.

Note that the methods of Array below are supported by all modern browsers. So we did not include wrappers for them.

 

  • .concat()
  • .pop()
  • .push()
  • .shift()
  • .slice()]
  • .splice(
  • .unshift()

Methods

 

Array.indexOf(elm)

 

parameters

elm - The element to seek its index.

 

returns

The first occurrence of elm, -1 if there is no match.

 

comments

Returns the index of the first occurrence of elm in the array.

Array.contains(elm)

 

parameters

elm - The element to check.

 

returns

true if the array contains elm, false otherwise.

 

comments

Checks whether or not the Array contains elm.

Array.copy()

 

returns

A copy of the original array.

 

comments

Copies the contents of an array and returns it.

 

If any element of the array is copyable (i.e. it is an Array or

has a copy method available) those elements are copied as well.

 

Otherwise primitive members (strings,numbers) ar copied but

objects (functions,associative arrays,vendor-specific objects etc.)

are passed by ref.
