-
DOMStringListis an interface representing an ordered collection ofDOMStringvalues, accessible by index starting from 0. -
It provides methods to check if a string is in the list (
contains), get the list's size (getLength), and retrieve an item by its index (item). -
If an index provided to the
itemmethod is out of bounds, it will returnnull.
The DOMStringList interface provides the abstraction of an
ordered collection of DOMString values, without defining or
constraining how this collection is implemented. The items in the
DOMStringList are accessible via an integral index, starting
from 0.

indexth item in the collection. |
Public Methods
public abstract boolean contains (String str)
Test if a string is part of this DOMStringList.
Parameters
| str | The string to look for. |

Returns
trueif the string has been found,falseotherwise.
public abstract int getLength ()
The number of DOMStrings in the list. The range of valid
child node indices is 0 to length-1 inclusive.
public abstract String item (int index)
Returns the indexth item in the collection. If
index is greater than or equal to the number of
DOMStrings in the list, this returns null.
