jQuery Autocomplete


jQuery Autocomplete 插件根据用户输入值进行搜索和过滤,让用户快速找到并从预设值列表中选择。通过给 Autocomplete 字段焦点或者在其中输入字符,插件开始搜索匹配的条目并显示供选择的值的列表。通过输入更多的字符,用户可以过滤列表以获得更好的匹配。

该插件现在是 jQuery UI 的一部分,独立的版本不会再更新了。目前版本是 1.6。

访问 jQuery Autocomplete 官网,下载 jQuery Autocomplete 插件。

如需了解更多有关 Autocomplete 的细节,请查看 API 文档 自动完成部件(Autocomplete Widget)
