NodeList
interface NodeList
The NodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. NodeList objects in the DOM are live.
The items in the NodeList are accessible via an integral index, starting from 0.
See also the Document Object Model (DOM) Level 3 Core Specification.
Summary
| Public methods |
| abstract Int |
The number of nodes in the list.
|
| abstract Node! |
Returns the indexth item in the collection.
|
Public methods
getLength
abstract fun getLength(): Int
The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.
item
abstract fun item(index: Int): Node!
Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null.
| Parameters |
index |
Int: Index into the collection. |
| Return |
Node! |
The node at the indexth position in the NodeList, or null if that is not a valid index. |
