如何在ExtJS(Javascript)裡面拷貝(克隆）一個Object

對于ExtJS可以使用這段代碼：

/**      

* 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
