requirejs之demo
具体的理论就不讲了，可以参考

直接上demo
首先创建文件，其中define的是采取amd格式定义的
// require1.js
define(function (){
var add = function (x,y){
return x+y;
};
return {
add: add
};
});
// require2.js
define(function (){
var multiply = function (x,y){
return x*y;
};
return {
multiply: multiply
};
});
// require3.js
define(function(){
var divide=function(a,b){
return a/b;
};
return {
divide:divide
};
})
// noAMD.js
function test2(a,b){
return a-b;
}
window.test=test2;
//main.js
require.config({
paths: {
"require1": "src/require1",
"require2": "src/require2",
"test":"src/noAMD"
},
shim:{
"test":{
exports:"test"
}
}
});
require(["require1","require2","src/require3",'test'],function(require1,r2,r3,test2){
var a=21,b=3;
alert(require1.add(a,b));
alert(r2.multiply(a,b));
alert(r3.divide(a,b));
alert(test2(a,b))
})
<html>
<head>
<meta name="generator"
content="HTML Tidy for HTML5 (experimental) for Windows https://github.com/w3c/tidy-html5/tree/c63cc39" />
<title></title>
<script src="require.js" data-main="main" defer async="true">
</script>
</head>
<body></body>
</html>
此处需要注意非amd格式编写的，需要使用shim
