利用requirejs异步调用js文件的例子

// r.js 打包 准备
var files = grunt.file.expand('js/app/*/main.js'); //读取要打包的js入口 一般都为 main的js
var requirejsOptions = {}; //用来存储 打包配置的对象
 
//遍历文件
files.forEach(function(file) {
    var filenamelist = file.split('/');
    var num = filenamelist.length;
    var filename = filenamelist[num - 2]; //获取目录名称，因为这里的文件名都是main的js
    requirejsOptions[filename] = {
        options: {
            baseUrl: "js/",
            paths: {
                "text": 'lib/text',
                "jquery": 'lib/jquery',
                "backbone": 'lib/backbone',
                "underscore": 'lib/underscore',
                "Highcharts": 'lib/highcharts/highcharts',
                "select2": 'lib/select2/select2',
                "moment": 'lib/moment',
                "jquery-ui": 'lib/jquery-ui/jquery-ui',
                "jquery.cookie": 'lib/jquery.cookie',
                "validate": 'lib/jquery.validate',
                "metadata": 'lib/jquery.metadata',
                "jsplumb": "lib/jquery.jsPlumb",
                "qtip": 'lib/qtip/jquery.qtip',
                "nicescroll": "lib/jquery.nicescroll",
                "Htheme": 'lib/highcharts/theme',
                'jquery.mousewheel': 'lib/jquery.mousewheel'
            },
            optimizeAllPluginResources: true,
            name: 'app/' + filename + '/main',
            out: 'js/appbuild/' + filename + '/main.js'
        }
    };
});
//

//*****省略其他代码
        requirejs: requirejsOptions
 
 
    });
    // Default task(s).
    grunt.registerTask('dev', [
        'compass:force',
        'connect:server',
        'watch'
    ]);
    grunt.registerTask('dist', [
        'compass:force'
    ]);
    grunt.registerTask('js', ['requirejs']);
