关于apply，把两个对象属性赋给另一个对象解决办法

关于apply，把两个对象属性赋给另一个对象
想把两个对象赋给另一个对象，用apply怎么实现？
比如

JScript code

var a = {"A":"a"};var b = {"B":"b"};var c;//把a,b赋值给c,让c有"A","B"属性

[解决办法]
var c={};
$.extend(c,a,b);
//---------------------------------

用 apply太绕 还要给a b 对象加方法才行 如下
var a ={a:1,aa:2,aaa:3,extend:function(obj){
for(var name in obj)
this[name] = obj[name];
}},
c ={c:1,cc:2,ccc:3,extend:function(obj){
for(var name in obj)
this[name] = obj[name];
}}
b={};
a.extend.apply(b,[a]);
c.extend.apply(b,[c]);
alert(b.toSource())
[解决办法]
如果有单独的extend函数 是可以不需要 给 a,b加方法的

JScript code

    var extend = function(){        var target = arguments[0] || {}, i = 1, length = arguments.length, deep = true, options;        if ( typeof target === "boolean" ) {            deep = target;            target = arguments[1] || {};            i = 2;        }        if ( typeof target !== "object" && Object.prototype.toString.call(target)!="[object Function]")            target = {};        for(;i<length;i++){            if ( (options = arguments[ i ]) != null )                for(var name in options){                    var src = target[ name ], copy = options[ name ];                    if ( target === copy )                        continue;                    if ( deep && copy && typeof copy === "object" && !copy.nodeType ){                        target[ name ] = arguments.callee( deep, src || ( copy.length != null ? [ ] : { } ), copy );                    }                       else if(copy !== undefined)                        target[ name ] = copy;                                       }            }        return target;               };    var a ={a:1,aa:2,aaa:3,aaaa: function(){}},    c ={c:1,cc:2,ccc:3,cccc:function(){}}    b={};    extend(b,a,c);    alert(b.toSource());
[解决办法]
JScript code
var a = {"A":"a"};var b = {"B":"b"};var c;c=a;for(var i in b){  c[i] = b[i];}console.log(c);
[解决办法]
简单的写了个最暴力的extend
JScript code
var a = {"A":"a"};var b = {"A":"xxxxx","B":"b"};function extend(a,b){    for(var n2 in b){        a[n2]=b[n2];    }    return a;}var c=extend(a,b);alert(c.B);
