jQuery UI 实例 – 自动完成(Autocomplete)
jQuery UI 实例 - 自动完成(Autocomplete)
jQuery UI的自动完成(Autocomplete)是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。
如需了解更多有关autocomplete部件的细节,请查看API文档自动完成部件(Autocomplete Widget)。
默认功能
当您在输入域中输入时,自动完成(Autocomplete)部件提供相应的建议。在本实例中,提供了编程语言的建议选项,您可以输入"ja"尝试一下,可以得到Java或 JavaScript。
数据源是一个简单的JavaScript数组,使用source选项提供给部件。

包含重音
autocomplete域使用自定义的source选项来匹配带有重音字符的结果项,即使文本域不包含重音字符也会匹配。但是如果您在文本域中键入了重音字符,则不会显示非重音的结果项。
尝试键入"Jo",会看到"John"和"Jörn",然后键入"Jö",只会看到"Jörn"。

组合框(Combobox)
一个由Autocomplete和Button创建的自定义部件。您可以键入一些字符,来获得基于您的输入过滤的结果,或者使用按钮从完整列表中选择。
该输入是从一个已有的select元素中读取,传递给带有自定义的source选项的Autocomplete。
这是一个不被支持的不完美的部件。这里纯粹是为了演示autocomplete定制功能。如需了解更多有关该部件工作原理的细节,请点击这里查看相关的jQuery文章。

自定义数据并显示
您可以使用自定义数据格式,并通过简单地重载默认的聚焦和选择行为来显示数据。
尝试键入"j",或者按向下箭头按键,即可得到一个项目列表。

远程 JSONP 数据源
当您在文本域中键入字符时,Autocomplete部件给出建议结果。在本实例中,当您在文本域中至少键入两个字符时,将显示相关城市的名称。
在本实例中,数据源是geonames.org webservice。虽然选择一个元素后文本域中是该城市名称,但是会显示更多的信息以便找到正确的条目。数据也可以回调,显示在下面的结果框中。

远程数据源
当您在文本域中键入字符时,Autocomplete部件给出建议结果。在本实例中,当您在文本域中至少键入两个字符时,将显示相关鸟的名称。
在本实例中,数据源是可返回JSON数据的服务器端脚本,通过一个简单的source选项来指定。另外,minLength选项设置为2,避免查询返回太多的结果,select事件用于显示一些反馈。

当您在文本域中键入字符时,Autocomplete部件给出建议结果。在本实例中,当您在文本域中至少键入两个字符时,将显示相关鸟的名称。
为了提高性能,这里添加了一些本地缓存,其他与远程数据源实例相似。在这里,缓存只保存了一个查询,并可以扩展到缓存多个值,每个条目一个值。

可滚动的结果
当显示一个长列表的选项时,您可以简单地为autocomplete菜单设置max-height来防止菜单显示太长。尝试键入"a"或"s"来获得一个可滚动的长列表的结果。

XML 数据
