javascript - 相当于服务器端的 "window["functionName"](arguments)"

NodeJS服务端window["functionName"](arguments)的等效代码是什么? 最佳答案 如果您在模块中需要这样的功能,一种技巧是将此类模块函数存储在模块内的变量中,然后通过从模块对象属性访问它们来调用它们。示例:varx={};//betterwouldbetohavemodulecreateanobjectx.f1=function(){console.log('Callmeasastring!');}现在,在模块中,您可以使用字符串中的值调用它:varfuncstr="f1";x[funcstr]();
