RequireJS 按需加载js模块
1.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.js"></script>
</head>
<body>
<input type="button" id="button1" value="Click">
<input type="button" id="button2" value="Click">
<script src="https://cdn.bootcss.com/require.js/2.3.5/require.js" data-main="js/index"></script>
</body>
</html>
2.上面html文件中data-main对应的index.js文件
require.config({
baseUrl: 'js'
});
require(['myModule'], function (myModule){
$('#button1').click(function () {
alert('button1');
});
myModule.myFun();
});
3.上面index.js文件中对应myModue.js文件
define(function (){
var myModule = {
myFun: function () {
$('#button2').click(function () {
alert('button2');
});
}
};
return myModule;
});
4.目录结构
