Implementation Note: The specification for the JavaScript add() method actually calls for the optional newIndex parameter to be an integer. However, the newIndex parameter is specified as an Object here rather than an int because of the way Rhino and HtmlUnit process optional parameters for the JavaScript method calls. If the newIndex parameter were specified as an int, then the Undefined value for an integer is specified as NaN (Not A Number, which is a Double value), but Rhino translates this value into 0 (perhaps correctly?) when converting NaN into an int. As a result, when the newIndex parameter is not specified, it is impossible to make a distinction between a caller of the form add(someObject) and add (someObject, 0). Since the behavior of these two call forms is different, the newIndex parameter is specified as an Object. If the newIndex parameter is not specified by the actual JavaScript code being run, then newIndex is of type net.sourceforge.htmlunit.corejs.javascript.Undefined. If the newIndex parameter is specified, then it should be of type java.lang.Number and can be converted into an integer value.
This method will call the put(int, Scriptable, Object)
method for actually
adding the element to the collection.
According to the Microsoft DHTML reference page for the JavaScript add() method of the options collection, the index parameter is specified as follows:
newOptionObject
- the DomNode to insert in the collectionnewIndex
- An optional parameter which specifies the index position in the
collection where the element is placed. If no value is given, the method places
the element at the end of the collection.put(int, Scriptable, Object)
