关于jquery
seajs module 在使用jquery框架时,有两种加载方式:
1.就像在seajs模块中引入的一样,设置alias == 这里的jquery被改造了,
里面添加了代码,应用seajs模块定义规范和没有冲突的设置
所有模块都是异步加载的
如果seajs之后还有其他模块使用到了jquery框架,不能保证jquery已经加载完成
line 9578
// Expose jQuery to the global object
window.jQuery = window.$ = jQuery;
// Expose jQuery as an AMD module, but only for AMD loaders that
// understand the issues with loading multiple versions of jQuery
// in a page that all might call define(). The loader will indicate
// they have special allowances for multiple jQuery versions by
// specifying define.amd.jQuery = true. Register as a named module,
// since jQuery can be concatenated with other files that may use define,
// but not use a proper concatenation script that understands anonymous
// AMD modules. A named AMD is safest and most robust way to register.
// Lowercase jquery is used because AMD module names are derived from
// file names, and jQuery is normally delivered in a lowercase file name.
// Do this after creating the global so that if an AMD module wants to call
// noConflict to hide this version of jQuery, it will work.
if ( typeof define === "function" ) {
define("jquery/jquery/1.9.1/jquery-debug", [], function () { return jQuery; } );
}
})( window );
;$.noConflict();
</code>
2.在seajs之前引入原版的jquery 这样拥有全局的$,针对不是seajs模块的其他js来说,保证再其
依赖jquery之前就已经将jquery引入并且暴露出$和jquery 变量
但是无法保证其他模块的$冲突问题
