RequireJs学习笔记之data-main Entry Point

You will typically use a data-main script to set configuration options and then load the first application module. Note: the script tag require.js generates for your data-main module includes the async attribute. This means that you cannot assume that the load and execution of your data-main script will finish prior to other scripts referenced later in the same page.

翻译：通常会使用data-main设置的脚本里写一些配置选项，然后读取你配置里的第一个程序模块，注意require.js生成的data-main模块里的配置包含异步属性，注意你无法确定在同一个页面里面，你的data-main设置的脚本会在你其他脚本之前运行完，其他就是只的在文件位置上data-main后面的脚本

script data-main="scripts/main" src="scripts/require.js"></script>
<script src="scripts/other.js"></script>---》这个就是其他所指的文件

For example, this arrangement will fail randomly when the require.config path for the 'foo' module has not been set prior to it being require()'d later:

例如这个写法就会很容易造成问题，require.config配置的这个path属性没有在require()执行前设置，而是是在他执行后设置

<script data-main="scripts/main" src="scripts/require.js"></script>--》标签1
<script src="scripts/other.js"></script>--》标签2

// contents of main.js:
require.config({
    paths: {
        foo: 'libs/foo-1.1.3'
    }
});

// contents of other.js:

// This code might be called before the require.config() in main.js-》
// has executed. When that happens, require.js will attempt to-》
// load 'scripts/foo.js' instead of 'scripts/libs/foo-1.1.3.js'
//翻译:下面的代码或许在require.config()执行之前就被调用了,

//会造成require.js会加载script目录下的foo.js。而不是scripts/libs下的foo-1.1.3，
//在不设置baseUrl情况下requirejs会默认加载引用了requirejs文件所在的目录里的模块-》src="scripts/require.js"的

//总结就是说 不要以为标签2在标签1下面。标签1里的东西就会执行完

require( ['foo'], function( foo ) {

});
