JavaScript手册

此参考中包含的内容

This reference is organized around the 函数ality of the JavaScript language. Sometimes you already know the name of an object or method, but don't know precisely where to look for it. This chapter contains tables of links to aid in this situation.

表 1, "Operators," is a list of all JavaScript operators, grouped by type of operator.

表 2, "Statements," is an alphabetical list of all JavaScript statements.

表 3, "Objects with their methods and properties," is an alphabetical list of all of JavaScript's predefined classes and objects. The predefined methods and properties for each object are listed.

表 4, "Methods," is an alphabetical list of all predefined methods, regardless of the object to which they belong. The second column indicates the object with which the method is associated. There are separate entries for methods of the same name used in different objects. Each method name links to the method in the indicated object.

Similarly, 表 5, "Properties," is an alphabetical list of all predefined properties, regardless of the object to which they belong. The second column indicates the object with which the property is associated.

表 6, "Global 函数s," is an alphabetical list of JavaScript's global 函数s. These are 函数s which aren't associated with any object.

表 7, "Event handlers," is an alphabetical list of all JavaScript event handlers.

Key to the versions

If there is an entry in both the Client Version and the Server Version columns for a single construct, that construct is part of the core language. Otherwise, it is defined only for the client or for the server, as indicated.

The version number indicates the versions of Netscape Navigator (Nav), LiveWire (LW), or the Netscape servers (Svr), such as Enterprise Server and FastTrack Server), for which the construct is defined.

A plus sign after a version number (as in Nav 3+) indicates that the construct is defined for that version and all later versions (In the case of server constructs, LW 1+ indicates the construct was defined for LiveWire 1.0 and continues to be defined in Netscape 3.x servers.)

If there is no plus sign (Nav 3) or there is a range (Nav 2-3), the construct was only defined for the named releases.

A construct that has existed for more than one release may have had changes between releases. For this information, see the entry for the construct.
