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 原始网页：http://www.extjs.com/forum/showthread.php?t=26644
