小试身手

还记得jQuery如何使用的么?Sea.js也是如此。例子在这里可以找到,用anywhere起个静态服务来看看。

首先写个模块:

// File:js/module/greet.js
define(function (require, exports) {
    function helloPython() {
        document.write("Hello,Python");
    }
    function helloJavaScript() {
        document.write("Hello,JavaScript");
    }
    exports.helloPython = helloPython;
    exports.helloJavaScript = helloJavaScript;
});

如果你对Node.js非常熟悉,你可以把这个模块理解为Node.js的模块加上一个Wrapper。

在页面中引入Sea.js:

<!-- File:index.html -->
<!DOCTYPE HTML>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Getting start with Sea.js</title>
    <!-- 引入seajs-->
    <script src="/js/sea.js"></script>
</head>
<body>
    
</body>
</html>

加载模块文件!

<!DOCTYPE HTML>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Getting start width Sea.js</title>
    <!-- 引入seajs-->
    <script src="/js/sea.js"></script>
    <script>
        seajs.use(['/js/module/greet'], function (Greet) {
            Greet.helloJavaScript()
        })
    </script>
</head>
<body>

</body>
</html>

看到页面上输出的Hello,JavaScript么,这确实太简单了!
