使用grunt合并压缩js和css文件的方法

--src/  ajax.js  assets.js  callbacks.js  data.js  deferred.js  detect.js  event.js  form.js  fx.js  fx_methods.js  gesture.js  ie.js  ios3.js  selector.js  stack.js  touch.js  zepto.js

dist/node_modules/src/Gruntfile.jspackage.jsonpackage.json是依赖库文件Gruntfile.js是执行步骤程序

{ "name": "demo", "file": "zepto", "version": "0.1.0", "description": "demo", "license": "MIT", "devDependencies": {  "grunt": "~0.4.1",  "grunt-contrib-jshint": "~0.6.3",  "grunt-contrib-concat": "~0.5.0",  "grunt-contrib-uglify": "~0.2.1",  "grunt-contrib-requirejs": "~0.4.1",  "grunt-contrib-copy": "~0.4.1",  "grunt-contrib-clean": "~0.5.0",  "grunt-strip": "~0.2.1" }, "dependencies": {  "express": "3.x" }}

module.exports = function (grunt) { grunt.initConfig({ concat: {  options: {  },  dist: {   src: ['src/**/*.js'],//src文件夹下包括子文件夹下的所有文件   dest: 'dist/built.js'//合并文件在dist下名为built.js的文件  } }, uglify: {   build: {    src: 'dist/built.js',//压缩源文件是之前合并的buildt.js文件    dest: 'dist/built.min.js'//压缩文件为built.min.js   }  }}); grunt.loadNpmTasks('grunt-contrib-uglify'); grunt.loadNpmTasks('grunt-contrib-concat'); grunt.registerTask('default', ['concat','uglify']);}
