export f; // 正确 export function f() {}; // 正确 function f() {} export {f}; And:export语句输出的接口,都是和其对应的值是动态绑定的关系,即通过该接口取到的都是模块内部实时的值。 位置:export模块可以位于模块中的任何位置,但是必须是在模块顶层,如果在其他作用域内,会报错。 function foo()...
原因是,export是ECMA为将来保留的词(Words reserved for ECMA extensions)。 下面把OReilly.JavaScript.The.Definitive.Guide.5th.Edition 2.8. Reserved Words的内容: JavaScript has a number of reserved keywords.These are words that you cannot use as identifiers (variable names, function names, and loop la...
在不同的模块或JS文件中更改变量可以通过以下几种方式实现: 1. 全局变量:将变量定义在全局作用域中,使其在整个应用程序中可访问。在一个模块中声明变量,然后在其他模块中使用该变量即可。然而,全局变量...
在这个规范下,每个.js文件都是一个模块,它们内部各自使用的变量名和函数名都互不冲突,例如,hello.js和main.js都申明了全局变量var s = 'xxx',但互不影响。 一个模块想要对外暴露变量(函数也是变量),可以用module.exports = variable;,一个模块要引用其他模块暴露的变量,用var ref = require('module_name');...
// test.js var globalVar; function funcName(firstLongName, anotherLongName) { var myVariable = firstLongName + anotherLongName; } var code = fs.readFileSync("test.js", "utf8"); UglifyJS.minify(code).code; // 'function funcName(a,n){}var globalVar;' UglifyJS.minify(code, { man...
However, what if we want to export this function directly, and not as the property of some object? We can overwrite exports to do this, but we must not treat it as a global variable then: // a.jsmodule.exports=function(user, password, done) { ... } ...
