如何在ExtJS(Javascript)里面拷贝(克隆）一个Object

对于ExtJS可以使用这段代码：

/**

 * Clone Function

 * @param {Object/Array} o Object or array to clone

 * @return {Object/Array} Deep clone of an object or an array

 * @author Ing. Jozef Sakáloš

 */

Ext.ux.util.clone = function(o) {

    if(!o || 'object' !== typeof o) {

        return o;

    }

    if('function' === typeof o.clone) {

        return o.clone();

    }

    var c = '[object Array]' === Object.prototype.toString.call(o) ? [] : {};

    var p, v;

    for(p in o) {

        if(o.hasOwnProperty(p)) {

            v = o[p];

            if(v && 'object' === typeof v) {

                c[p] = Ext.ux.util.clone(v);

            }

            else {

                c[p] = v;

            }

        }

    }

    return c;

}; // eo function clone
