		 * 第五个参数表示来填充的组件 Map对象key对应的资源一依次填充组件 顺序有对应关系
		 * 注意的是map对象可以key可以找不到 但组件的必须要有资源填充  因为 找不到key也会返回null 其实就相当于给了一个null资源

       学习jquery有些时间了,感觉jquery的封装的特性特别出色,尤其是屏蔽了复杂的DOM操作,在以往的操作中,定位一个标记,总要想文档,树这些概念,但是在jquery中,只要和css一样的写法,就可以快速定位一个标记.

ul,li{
	margin:0px;
	padding:0px;
	list-style:none;
}

.Loading{
	width:400px;
	/*margin-left:auto;
	//margin-right:auto;*/
	margin:0 auto;
	visibility:hidden;
		
}

#contentsecond{
	width:300px;
	height:100px;
}

$("#realcontent").load("test.html");

$("div.contentin").removeClass("contentin");

	function setBorder( n )
	{
	    document.getElementById( "image1" ).border = n;
	} 

	(function() { 
	var 
	// Will speed up references to window, and allows munging its name. 
	window = this, 
	// Will speed up references to undefined, and allows munging its name. 
	undefined, 
	// Map over jQuery in case of overwrite 
	_jQuery = window.jQuery, 
	// Map over the $ in case of overwrite 
	_$ = window.$, 
	jQuery = window.jQuery = window.$ = function(selector, context) { 
	// The jQuery object is actually just the init constructor 'enhanced' 
	return new jQuery.fn.init(selector, context); 
	}, 
	// A simple way to check for HTML strings or ID strings 
	// (both of which we optimize for) 
	quickExpr = /^[^<]*(<(.|\s)+>)[^>]*$|^#([\w-]+)$/, 
	// Is it a simple selector 
	isSimple = /^.[^:#\[\.,]*$/; 
	jQuery.fn = jQuery.prototype = { 
	init: function(selector, context) { 
	// Make sure that a selection was provided 
	// Make sure that a selection was provided 
	selector = selector || document; 
	this[0] = selector; 
	this.length = 1; 
	this.context = selector; 
	return this; 
	}, 
	show:function() { 
	alert("this.show"); 
	}, 
	// Start with an empty selector 
	selector: "", 
	// The current version of jQuery being used 
	jquery: "1.3.2" 
	}; 
	jQuery.fn.init.prototype = jQuery.fn; 
	})(); 
	function test(src){ 
	alert($(src)); 
	$(src).show();

通过对代码的简单理解，我们不难发现，jquery简单的背后做了大量的总结及抽象工作，所以我们可以这么总结：
    1，要向写好代码，必须不断优化改进！
    2，要向做好软件，尽量灵活抽象是正道
    3，一个团队的管理，犹如设计一个页面，快速定位某项工作的基础是有一个全局的管理观念（参考代码中的window）
