vm.compileFunction(code[, params[, options]])

• code <string> 要编译的函数体。

  ¥code <string> The body of the function to compile.

• params <string[]> 包含函数所有参数的字符串数组。

  ¥params <string[]> An array of strings containing all parameters for the function.

• options <Object>

  • filename <string> 指定此脚本生成的堆栈跟踪中使用的文件名。默认值：''。

    ¥filename <string> Specifies the filename used in stack traces produced by this script. Default: ''.

  • lineOffset <number> 指定在此脚本生成的堆栈跟踪中显示的行号偏移量。默认值：0。

    ¥lineOffset <number> Specifies the line number offset that is displayed in stack traces produced by this script. Default: 0.

  • columnOffset <number> 指定在此脚本生成的堆栈跟踪中显示的第一行列号偏移量。默认值：0。

    ¥columnOffset <number> Specifies the first-line column number offset that is displayed in stack traces produced by this script. Default: 0.

  • cachedData <Buffer> | <TypedArray> | <DataView> 为所提供的源提供可选的 Buffer 或 TypedArray 或 DataView，其中包含 V8 的代码缓存数据。

    ¥cachedData <Buffer> | <TypedArray> | <DataView> Provides an optional Buffer or TypedArray, or DataView with V8's code cache data for the supplied source.

  • produceCachedData <boolean> 指定是否产生新的缓存数据。默认值：false。

    ¥produceCachedData <boolean> Specifies whether to produce new cache data. Default: false.

  • parsingContext <Object> 应在其中编译所述函数的 contextified 对象。

    ¥parsingContext <Object> The contextified object in which the said function should be compiled in.

  • contextExtensions <Object[]> 包含要在编译时应用的上下文扩展集合（包含当前作用域的对象）的数组。默认值：[]。

    ¥contextExtensions <Object[]> An array containing a collection of context extensions (objects wrapping the current scope) to be applied while compiling. Default: [].

  • importModuleDynamically <Function> 在调用 import() 时在评估此模块期间调用。如果未指定此选项，则调用 import() 将使用 ERR_VM_DYNAMIC_IMPORT_CALLBACK_MISSING 拒绝。此选项是实验模块 API 的一部分，不应被视为稳定的。

    ¥importModuleDynamically <Function> Called during evaluation of this module when import() is called. If this option is not specified, calls to import() will reject with ERR_VM_DYNAMIC_IMPORT_CALLBACK_MISSING. This option is part of the experimental modules API, and should not be considered stable.

    • specifier <string> 说明符传递给 import()

      ¥specifier <string> specifier passed to import()

    • function <Function>

    • importAssertions <Object> 传给 optionsExpression 可选参数的 "assert" 值，如果没有提供值，则为空对象。

      ¥importAssertions <Object> The "assert" value passed to the optionsExpression optional parameter, or an empty object if no value was provided.

    • 返回：<Module Namespace Object> | <vm.Module> 建议返回 vm.Module 以利用错误跟踪，并避免包含 then 函数导出的命名空间出现问题。

      ¥Returns: <Module Namespace Object> | <vm.Module> Returning a vm.Module is recommended in order to take advantage of error tracking, and to avoid issues with namespaces that contain then function exports.

• 返回：<Function>

  ¥Returns: <Function>

将给定的代码编译到提供的上下文中（如果没有提供上下文，则使用当前上下文），并返回它封装在具有给定 params 的函数中。

¥Compiles the given code into the provided context (if no context is supplied, the current context is used), and returns it wrapped inside a function with the given params.
