javascript对象复制

function clone(obj) {
            var newObj;
            if (typeof obj === 'object') {
                if (Object.prototype.toString.call(obj) === '[object Array]') {
                    newObj = [];
                    var i = obj.length;
                    while (i--) {
                        newObj[i] = this.clone(obj[i]);
                    }
                    return newObj;
                } else {
                    newObj = {};
                    for (var j in obj) {
                        newObj[j] = this.clone(obj[j]);
                    }
                }
            } else {
                return obj;
            }
            return newObj;
        }

 

 

 jquery参考如下:

参考: http://www.css88.com/jqapi-1.9/jQuery.extend/

// 浅层复制(只复制顶层)

 

var newObject = jQuery.extend({}, oldObject);

 

// 深层复制(递归复制)

 

var newObject = jQuery.extend(true, {}, oldObject);
