cb.utils.extend
<pre><code>说明：拷贝对象/数组
入参：deep(是否深拷贝),target(拷贝类型 {}||[]),obj(需要拷贝的对象/数组)
例：
1、var a = {a1:{a11:2}}
var b = cb.utils.extend(false,{},a)；
b.a1.a11 = 3;
输出：a =&gt; {a1:{a11:3}} ; b =&gt; {a1:{a11:3}}
2、var a = {a1:{a11:2}}
var b = cb.utils.extend(true,{},a)；
b.a1.a11 = 3;
输出：a =&gt; {a1:{a11:2}} ; b =&gt; {a1:{a11:3}} </code></pre>
