1、seajs使用外部依赖（第三方工具库，譬如jQuery）
错误做法：
define(function(require, exports, module){ ??????// ?require可以下载外部依赖，但是他不能将其解析为seajs自身的模块，所以不能这样使用。 ???var $ = require(‘../../depency/3rd_lib/jquery.js‘); ???$(‘#hi‘).html("aaaaaa"); ??});正确做法1：
index.html<html> ????<head> ???????<title>sea demo</title> ???????<!-- <script type="text/javascript" src="../depency/3rd_lib/jquery.js"></script> --> ???????<script type="text/javascript" src="../depency/3rd_lib/sea-debug.js"></script> ???</head><body><div id="hi"></div> ???<script type="text/javascript"> ???seajs.use(‘../static/test/seaUtil.js‘, function(){ ????????seajs.use(‘../static/test/seajsDemo.js‘); ???????});</script> ???</body></html>seaUtil.js ???????????define(function(require, exports, module){ ???????/** ????* ?require可以下载外部依赖，但是他不能将其解析为seajs自身的模块，所以不能这样使用。 ????* ?外部依赖引入推荐做法： ????* ????1、将外部依赖单独放到一个seajs文件模块中引入，在首页seajs.use的callback里use其他模块，在callback中引入其他初始模块可以防止依赖未引入时使用 ????* ????2、将外部依赖放在首页HTML中加载，在seajs文件模块中直接使用 ????*/ ????????require(‘../../depency/3rd_lib/jquery.js‘); ???// $(‘#hi‘).html("aaaaaa"); ??});seajsDemo.js ????define(function(require, exports, modeule){ ???var seaUtil = require(‘./seaUtil‘); ???eBase = window.eBase = window.eBase || {}; ????????app = window.app = window.app || {}; ????????????$.extend(eBase, { ???????sayHello: function(){ ???????????alert(‘hello , gray boy @‘); ???????} ???}); ???app.userManager = app.userManager || {}; ???}); ???????????????????正确做法2：
index.html ????<html><head><title>sea demo</title><script type="text/javascript" src="../depency/3rd_lib/jquery.js"></script><script type="text/javascript" src="../depency/3rd_lib/sea-debug.js"></script></head><body><div id="hi"></div> ???<script type="text/javascript"> ???seajs.use(‘../static/test/seaUtil.js‘, function(){ ????????seajs.use(‘../static/test/seajsDemo.js‘); ???????});</script> ???</body></html>seajsDemo.jsdefine(function(require, exports, modeule){ ???var seaUtil = require(‘./seaUtil‘); ???eBase = window.eBase = window.eBase || {}; ????????app = window.app = window.app || {}; ????????????$.extend(eBase, { ???????sayHello: function(){ ???????????alert(‘hello , gray boy @‘); ???????} ???}); ???app.userManager = app.userManager || {}; ???});seajs使用记
