克隆js对象

functioncloneObj(obj){ 

    function Clone(){} 

    Clone.prototype = obj; 

    var o = new Clone(); 

    for(var a in o){ 

        if(typeof o[a] == "object"){ 

            o[a] = cloneObj(o[a]); 

        } 

    } 

    return o; 

}

 

浅克隆

public classBookFill extends BaseModel implements Cloneable{

publicint aInt;

publicObject clone(){

BookFillo = null;

try{

o= (BookFill)super.clone();

}catch(CloneNotSupportedExceptione){

e.printStackTrace();

}

returno;

}

BookFillbook2=(BookFill) book.clone();

 

这样就可以了

}
