如何在extjs(javascript)里面拷贝(克隆）一个object(转)

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;};
