复制代码代码如下:

        
jQuery.fn = jQuery.prototype = {
        
constructor: jQuery,
        
init: function( selector, context, rootjQuery ) { },
        
selector: "",
        
jquery: "1.7.2",
        
length: 0,
        
size: function() {},
        
toArray: function() {},
        
get: function( num ) {},
        
pushStack: function( elems, name, selector ) {},
        
each: function( callback, args ) {},
        
ready: function( fn ) { },
        
eq: function( i ) {},
        
first: function() {},
        
last: function() { },
        
slice: function() {},
        
map: function( callback ) { },
        
end: function() { },
        
push: push,
        
sort: [].sort,
        
splice: [].splice
        
};

以上就是该版本的jQuery的原型上的部分属性和方法.
selector:用于记录init参数的selector.但不一定是相等的.
$("div").selector;//"div"
$("div").find(p).selecctor;//"div p";
这个属性一般用于调试.
jquery:jQuery的版本号.
length:元素的个数.
size():等效于length,length的内存开销更小.
剩下的成员在后面的章节中介绍.
