JavaScript has come a long way since its inception, and with the evolution of the language, modularity has become an essential part of writing clean, maintainable, and scalable code. In this blog post, we will discuss the require() function used in Ja
If these modules are in separate JavaScript files you should use them inside the original JavaScript code.In this chapter we will cover what the require() function does, how it can be used and some differences between the require and import functions....
Immediately Invoked Function Expression (IIFE for short) is a function that gets executed immediately after its declaration. To create an IIFE, you can use both the old function and new arrow function syntax: (function(){/* function definition */})()(()=>{/* function definition */})() ...
require(["jquery","showDate"],function($,showDate){ console.log($);//Jquery对象showDate.show();//1}); require(["testShim"],function(testShim){ testShim.fn1();//shim中exports定义的值与js模块中暴露的值一职才能正常运行}); .showDate.js define(function(){varnum = 10;functionshowDate(...
require(['main'], function(main) { // do something }); 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 2) 引入模块 引入模块要利用requirejs提供的API require // 引入的依赖模块和回调中的参数一一对应 require(['a', 'b', 'c'], function(...
m1 : function (){ //... }, m2 : function (){ //... } }); 注:类似的写法还有: var module1 = { _count : 0, m1 : function (){ //... }, m2 : function (){ //... } }; 因为在javascript中一般推荐使用 var obj = {}; 来定义对象,var arr = []; 来定义数组。
define(["jquery"],function($){// Put here the plugin code.}); 1. 2. 3. 2. 在使用reuqireJS代码加载前注册插件(比如在main.js)中 复制 requirejs.config({"shim": {"jquery-cookie": ["jquery"]}}); 1. 2. 3. 4. 5. requireJS加载第三方类库 ...
<!DOCTYPE html>body a.js: functionfun1(){alert("it works");}fun1(); 可能你更喜欢这样写 (function(){functionfun1(){alert("it works");}fun1();})() 第二种方法使用了块作用域来申明function防止污染全局变量,本质还是一样的,当运行上面两种例子时不知道你是否注意到,alert...
代码语言:javascript 复制 /** * The function that handles definitions of modules. Differs from * require() in that a string for the module should be the first argument, * and the function to execute after dependencies are loaded should ...
代码语言:javascript 复制 requirejs.config({baseUrl:'/public/js',paths:{hello:'hello'},shim:{hello:{exports:'hello'}}});requirejs(['hello'],function(hello){hello();}); 上面代码 exports: 'hello' 中的 hello ,是我们在 hello.js 中定义的 hello 函数。当我们使用 function hello() {} 的...
