"Turn" require.js study notes (i)

First, execute the function immediately

for (var i = 0; i < elems.length; i++) {    (function (lockedinindex) {          elems[i].addeventlistener (' click ', Functio N (e) {            e.preventdefault ();            Alert (' I am Link # ' + lockedinindex);        }, ' false ');    }) (i); Enter the argument}

Use the immediate execution function to achieve the purpose of not exposing private members

var Module1 = (function () {var _count = 0;　　　　var m1 = function () {//...};　　　　var m2 = function () {//...};　　return {m1:m1, m2:m2}; })();  Unable to read _count    

Compare immediate execution functions

Second, the module specification at present the main module specification has COMMONJS and AMD 1.commonJScommonJS is the server-side module specification, Nodejs follows this specification. Because the server JS file is stored locally, loading speed is fast, so its loading module (a file is a module) mode for synchronous loading, not applicable to the browser.
function Foobar () {        This.foo = function () {                console.log (' Hello foo ');        }        This.bar = function () {                console.log (' Hello bar ');}        } exports.foobar = Foobar;//export for external communication
var foobar = require ('./foobar '). Foobar,    test   
2.AMD takes the asynchronous load module, after loading completes through the callback function to implement the corresponding operation, applies with the browser.
Require ([' math '], function (math) {Math.add (2, 3); });
