JS::NewFunctionFromSpec 编辑

Create a new function based on the given JSFunctionSpec.

Syntax

JSFunction*
JS::NewFunctionFromSpec(JSContext* cx, const JSFunctionSpec* fs, HandleId id);

Description

JS::NewFunctionFromSpec creates a new function based on the given JSFunctionSpec, *fs. id is the result of a successful call to PropertySpecNameToPermanentId(cx, fs->name, &id).

Unlike JS_DefineFunctions, this does not treat fs as an array. *fs must not be JS_FS_END.

On success, JS::NewFunctionFromSpec returns a pointer to newly created function. On error, it returns nullptr.
