Javascript 使用IIFE函数之外的函数

Javascript 使用IIFE函数之外的函数,javascript,function,iife,Javascript,Function,Iife,我有以下方法,它位于someFile.js中: (function (root, factory) { if (typeof define === 'function' && define.amd) { // AMD. Register as an anonymous module. define(['b'], factory); } else if (typeof exports === 'object') { /

我有以下方法,它位于someFile.js中:

(function (root, factory) {
    if (typeof define === 'function' && define.amd) {
        // AMD. Register as an anonymous module.
        define(['b'], factory);
    } else if (typeof exports === 'object') {
        // Node. Does not work with strict CommonJS, but
        // only CommonJS-like environments that support module.exports,
        // like Node.
        module.exports = factory(require('b'));
    } else {
        // Browser globals (root is window)
        root.returnExports = factory(root.b);
    }
}(this, function (b) {
    //use b in some fashion.

    // Just return a value to define the module export.
    // This example returns an object, but the module
    // can return a function as the exported value.

        b.isValid = function(parameter){
            if (!isString(parameter)){
                return false;
            }
            parameter = this.newFormat(parameter);
            return parameter;
        };

}));
作为一个IIFE函数,它将自动调用自身,但我想在一个单独的JavaScript文件中使用该方法,类似于:

b.isValid('value to test');
这可能吗?或者,从IIFE函数外部访问或调用这些函数的最佳解决方案是什么


提前感谢。

您可以从factory函数返回一些值,然后将这些值分配给导出的
对象或根(或任何对象)

例如,module.js

(function (root, factory) {
    if (typeof define === 'function' && define.amd) {
            // AMD. Register as an anonymous module.
            define(['dependency'], factory);
        } else if (typeof exports === 'object') {
            // Node. Does not work with strict CommonJS, but
            // only CommonJS-like environments that support module.exports,
            // like Node.
            module.exports = factory(require('dependency'));
        } else {
            // Browser globals (root is window)
            root['identifier']= factory(root['dependency']);
        }
    })(this, function (dep) {

        // Just return a value to define the module export.
        // This example returns an object, but the module
        // can return a function as the exported value.

        return {
           fn: function(){
                console.log([].slice.call(arguments))
            }
        }

    });
index.html

<script src="module.js"></script>
<!-- Module will be executed in the global context and it's value will be assigned to the window object -->
<script>
    // can access the module's export here
    window['identifier'].fn('something', 'goes', 'here')
    // or, preferred way would be: identifier.fn('something', 'goes', 'here')
</script>

您可以将其分配到
窗口['b']
或将其返回到生命之外的变量?您使用UMD只是出于偶然吗?只需使用完全相同的模式,它就会神奇地工作。导入后,您正在向全局
b
模块添加一个方法,您可以以完全相同的方式将其导入其他文件中。我认为以这种方式变异(或扩展)依赖项不是一个好主意(除非
b
是某个库,
module
是某个插件或类似的东西)
// CommonJS
var depX = require("./module.js")  // can omit .js extension
depX.fn('something', 'goes', 'here')

// es6
import depX from "./module.js"  // can omit .js extension
depX.fn('something', 'goes', 'here')
