我搜索过但找不到答案，所以这是我的疑问，
可以获取一个对象并复制它吗？比如，我在我的视图（.xml）中有这个代码：
<View id="endereco1" class="" layout="horizontal" height="60dp" >
<Label class="input-left-label label-font-size label-text-align-right">CEP: </Label>
<TextField class="textArea"></TextField>
</View>
然后在我的Js上我想获取这个$ .endereco1，以及creat和$ .endereco2，只更改id，是否有可能，比如实例化在视图上写的对象？
提前谢谢

我的建议是你将该对象用作控制器，然后当你想获得重复的控制器时，在创建方法中发送相同的参数：
set_time_limit(0);
require_once($_SERVER['DOCUMENT_ROOT']."../../../home/username/public_html/config/config.php");
$host = 'localhost'; //host
$port = '9002'; //port
$null = NULL; //null var
//Create TCP/IP sream socket
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
//reuseable port
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
//bind socket to specified host
socket_bind($socket, 0, $port);
//listen to port
socket_listen($socket);
perform_handshaking($header, $socket_new, $host, $port);
//create & add listning socket to the list
$clients = array($socket);
//start endless loop, so that our script doesn't stop
while (true) {
//manage multipal connections
$changed = $clients;
//returns the socket resources in $changed array
socket_select($changed, $null, $null, 0, 10);
//check for new socket
if (in_array($socket, $changed)) {
$socket_new = socket_accept($socket); //accpet new socket
$clients[] = $socket_new; //add socket to client array
$header = socket_read($socket_new, 1024); //read data sent by the socket
perform_handshaking($header, $socket_new, $host, $port); //perform websocket handshake

或者创建一个返回第一个对象的函数：
var copy = Alloy.createController('view',argsUsedOnFirst).getView();

underscore.js内置于钛sdk中。为什么不简单地使用
clone
_.clone(object)
Create a shallow-copied clone of the provided plain object. Any nested objects or arrays will be copied by reference, not duplicated.
_.clone({name: 'moe'});
=> {name: 'moe'};
