Array
()
(

,
i
,
arraylike
)
Y.Array(o) returns an array:
- Arrays are return unmodified unless the start position is specified.
- "Array-like" collections (@see Array.test) are converted to arrays
- For everything else, a new array is created with the input as the sole item
- The start position is used if the input is or is like an array to return
a subset of the collection.
- Parameters:
-
o <object>the item to arrayify -
i <int>if an array or array-like, this is the start index -
arraylike <boolean>if true, it forces the array-like fork. This can be used to avoid multiple Array.test calls.
- Returns:
Array - the resulting array
each
static
YUI
each
(
a
,
f
,
o
)
Executes the supplied function on each item in the array.
- Parameters:
-
a <Array>the array to iterate -
f <Function>the function to execute on each item. The function receives three arguments: the value, the index, the full array. -
o <object>Optional context object
- Returns:
YUI - the YUI instance
hash
static
object
hash
(
k
,
v
)
Returns an object using the first array as keys, and
the second as values. If the second array is not
provided the value is set to true for each.
- Parameters:
-
k <Array>keyset -
v <Array>optional valueset
- Returns:
object - the hash
indexOf
static
int
indexOf
(
a
,
val
)
Returns the index of the first item in the array
that contains the specified value, -1 if the
value isn't found.
- Parameters:
-
a <Array>the array to search -
val <object>the value to search for
- Returns:
int - the index of the item that contains the value or -1
numericSort
void
numericSort
(
)
Numeric sort convenience function.
Y.ArrayAssert.itemsAreEqual([1, 2, 3], [3, 1, 2].sort(Y.Array.numericSort));
some
static
boolean
some
(
a
,
f
,
o
)
Executes the supplied function on each item in the array.
Returning true from the processing function will stop the
processing of the remaining
items.
- Parameters:
-
a <Array>the array to iterate -
f <Function>the function to execute on each item. The function receives three arguments: the value, the index, the full array. -
o <object>Optional context object
- Returns:
boolean - true if the function returns true on any of the items in the array
test
static
int
test
(
)
Evaluates the input to determine if it is an array, array-like, or
something else. This is used to handle the arguments collection
available within functions, and HTMLElement collections
- Returns:
int - a number indicating the results: 0: Not an array or an array-like collection 1: A real array. 2: array-like collection.
