See IDL grammar for the complete grammar and an explanation of the notation used. A specification that defines Web APIsĬan include one or more IDL fragments thatĭescribe the interfaces (the state and behavior that objects can exhibit)įor the APIs defined by that specification.Ī sequence of definitions that matches the Definitions grammar symbol.Īn implementation supports is not ordered. This section describes a language, Web IDL, which can be used to define Their interfaces using Web IDL, and then use prose to specify API-specific details. Iteration behavior, remain uniform across web platform specifications: such specifications describe ThisĮnsures common tasks, such as installing global properties, processing numeric inputs, or exposing Well as ECMAScript bindings that detail how those APIs manifest as ECMAScript constructs. How interfaces described with Web IDL correspond to constructs withinĮCMAScript execution environments is also detailed here.Ĭoncretely, Web IDL provides a syntax for specifying the surface APIs of web platform objects, as Number of features that allow the behavior of common script objects in the web platform to be Interfaces that are intended to be implemented in web browsers.
