设置公共变量node.js(Set public variables node.js)

设置公共变量node.js(Set public variables node.js)

我需要从static.js访问我在index.js中定义的变量，该变量使用require（）调用

Index.js

function API() { var self = this self.init = function(apikey, region, locale) { //Some stuff self.region = region self.locale = locale self.apikey = apikey self.static = require('./static').static } } module.exports = new API();

Static.js

module.exports = { static: { someFunction: function(someParameters) { //Need to access to self.region, self.locale and self.apikey }, otherFunction: function(someParameters) { //Need to access to self.region, self.locale and self.apikey } }

我的问题是使用static.js文件中的region，locale和apikey

Test.js var api = require（'./ index.js'）;

api.init('myKey', 'euw', 'en_US') console.log(api);

这样做：

RiotAPI { region: 'euw', locale: 'en_US', apikey: 'myKey', static: { someFunction: [Function], otherFunction: [Function] } }

这是好的，但当我用一个好的参数调用someFunction（）时，它告诉我self.region（以及其他我想的）没有被定义

I need to access to a variable that i define in my index.js from static.js which is called with require()

Index.js

function API() { var self = this self.init = function(apikey, region, locale) { //Some stuff self.region = region self.locale = locale self.apikey = apikey self.static = require('./static').static } } module.exports = new API();

Static.js

module.exports = { static: { someFunction: function(someParameters) { //Need to access to self.region, self.locale and self.apikey }, otherFunction: function(someParameters) { //Need to access to self.region, self.locale and self.apikey } }

My problem is to use region, locale and apikey from the static.js file

Test.js var api = require('./index.js');

api.init('myKey', 'euw', 'en_US') console.log(api);

does that:

RiotAPI { region: 'euw', locale: 'en_US', apikey: 'myKey', static: { someFunction: [Function], otherFunction: [Function] } }

which is okay but when i call someFunction() with the good arguments it tells me that self.region (and the others i guess) is not defined

最满意答案

您需要将static.js中的方法放在API实例的顶层。

var static = require('./static').static function API() { // constructor } API.prototype.init = function(apikey, region, locale) { //Some stuff this.region = region this.locale = locale this.apikey = apiKey } Object.assign(API.prototype, static) module.exports = new API();

然后在静态方法中引用this.region等。

You need to put the methods from static.js at the top-level of your API instance.

var static = require('./static').static function API() { // constructor } API.prototype.init = function(apikey, region, locale) { //Some stuff this.region = region this.locale = locale this.apikey = apiKey } Object.assign(API.prototype, static) module.exports = new API();

Then reference this.region etc. in your static methods.
