Javascript 模块.闭包中的导出
我可以这样称呼吗Javascript 模块.闭包中的导出,javascript,node.js,Javascript,Node.js,我可以这样称呼吗module.exports=yahoo;并在别处调用yahoo函数。您可以使用: test.js var object = {}; // Global Object (function() { var theArg, google, yahoo; object.google = function(arg) { theArg = arg; alert(theArg); } object.yahoo = fun
module.exports=yahoo
;并在别处调用yahoo
函数。您可以使用:
test.js
var object = {}; // Global Object
(function() {
var theArg, google, yahoo;
object.google = function(arg) {
theArg = arg;
alert(theArg);
}
object.yahoo = function() {
alert(theArg);
}
module.exports = yahoo;
})();
// This will set initial value of
google("Hello World");
var object = {}; // Global Object
alert = console.log;
(function() {
var theArg, google, yahoo;
object.google = function(arg) {
theArg = arg;
alert(theArg);
}
object.yahoo = function() {
alert(theArg);
}
module.exports.yahoo = object.yahoo;
})();
// This will set initial value of
object.google("Hello World");
main.js
var object = {}; // Global Object
(function() {
var theArg, google, yahoo;
object.google = function(arg) {
theArg = arg;
alert(theArg);
}
object.yahoo = function() {
alert(theArg);
}
module.exports = yahoo;
})();
// This will set initial value of
google("Hello World");
var object = {}; // Global Object
alert = console.log;
(function() {
var theArg, google, yahoo;
object.google = function(arg) {
theArg = arg;

我不明白。你如何才能调用
谷歌
?它是对象
的成员方法google
本身超出了范围。我不明白这一点。你如何才能调用谷歌
?它是对象
的成员方法google
本身不在范围之内。但是当我调用object.yahoo时,我没有收到警报。你在哪里调用它?在这个文件中,或者在您需要this的其他文件中?我是从不同的文件调用的。如果您直接使用alert,您将得到缺少函数的错误。改用console.log
