vm.runInContext()方法用于编译代码。它在contextifiedObject的上下文中运行代码,然后返回输出。此外,正在运行的代码无法访问本地范围,并且以前使用vm.createContext()方法将contextifiedObject对象上下文化。 用法: vm.runInContext( code, contextifiedObject, options ) 参数:此方法接受上述和以下所述的三个参数: code...
bar); // => true // 使用 `context` 模拟 `Date#getTime` 调用 `_.now` var mock = _.runInContext({ 'Date': function() { return { 'getTime': getTimeMock }; } }); // 或者在 Node.js 中创建一个更高级的 `defer` var defer = _.runInContext({ 'setTimeout': setImmediate })...
context:它包含必須使用其創建新函數的上下文對象。 返回值:此方法返回一個新的lodash函數。 範例1: javascript // Requiring the lodash libraryconst_ =require("lodash");// Creating an object variable_.mixin({'foo':_.constant('foo') });varfunc = _.runInContext(); func.mixin({'bar':func.cons...
runInContext('structuredClone(new Error()) instanceof Error', context); console.log('match:', result); You'll see that it is true. Take the following example, const vm = require('node:vm'); const context = vm.createContext({ func: (input) => input instanceof Object }); const ...
是因为在Node.js的vm模块中,runInNewContext方法默认不执行代码,而是返回一个可执行的函数。 vm模块是Node.js中的一个内置模块,用于在一个单独的沙箱环境中执行JavaScript代码。其中的runInNewContext方法可以在一个新的上下文中执行代码,并返回执行结果。
