推荐答案

查看 jQuery.serialize().它应该为您提供一组用户名.

Check out jQuery.serialize(). It should give you an array of the usernames.

var users = $('input:text.users').serialize();

您可以使用选择器，无论是懒惰还是特定:.users,input.users,form .users 都可以，加上还有一些.

You can be however lazy or specific with the selector: .users,input.users,form .users would all work, plus a few more.

对于这个例子:

// users = 
username[]=test1&username[]=test2&username[]=test3

这取决于您的服务器端技术，它将作为键用户名"(例如 PHP)的字符串数组出现在请求中.

Which, depending on your server-side technology, will come through in the request as an array of strings for the key "username" (PHP, for example).
