Js深度克隆对象（对象的属性含有对象数组）

这个方法当时在做项目时写的，应用在easyui的Tree组件中。

后台Java对象结构：List<TreeObj>

public class TreeObj {private String id;private String text;private List<TreeObj> children = new ArrayList<TreeObj>();private String state ;private String iconCls;private Object attributes ;private boolean checked = false;}

js代码：

//克隆树数据对象function clone(targetList,childrenList,cloneList){for(key in targetList){//----取值  start--------------------------------------------------------var obj = targetList[key];var newObj = {};newObj.id = obj.id;newObj.text = obj.text;newObj.state =obj.state;newObj.checked = obj.checked;var attr = {};attr.parentNode ="";attr.nodeHeirdomRelation = "";if(obj.attributes){if(obj.attributes.parentNode){attr.parentNode = obj.attributes.parentNode ;}if(obj.attributes.nodeHeirdomRelation){attr.nodeHeirdomRelation = obj.attributes.nodeHeirdomRelation ;}}newObj.attributes = attr;//---取值  end---------------------------------------------------------if(childrenList){childrenList.push(newObj);}//保存子节点成员if(obj.children != null && obj.children.length>0){var newList = new Array();//保存当前节点的子节点clone(obj.children,newList,cloneList);newObj.children = newList;}if(/^rl_.*$/.test(obj.id.toLowerCase())){//从根部开始保存cloneList.push(newObj);//保存根节点}}}

调用；

clone(源数组,null,克隆后);

 

在网上找到这个办法，但好像不能克隆带对象属性的数组，目前我还没对他进行过测试。

Object.prototype.Clone = function(){    var objClone;    if (this.constructor == Object){        objClone = new this.constructor();     }else{        objClone = new this.constructor(this.valueOf());     }    for(var key in this){        if ( objClone[key] != this[key] ){             if ( typeof(this[key]) == 'object' ){                 objClone[key] = this[key].Clone();            }else{                objClone[key] = this[key];            }        }    }    objClone.toString = this.toString;    objClone.valueOf = this.valueOf;    return objClone; }
