我想在一个html页面上有多个JQuery自动完成组合框的。 （如何）这是possibe？在一个页面上的多个jQuery自动完成组合框的实例
我发现组合框的id事项。在下面的例子中，用JQuery显示的唯一组合框是第一个。 我不喜欢复制（太多）JQuery脚本代码（我把这段代码放在.js文件中，并在.php文件中生成组合框）
我有这个（这只是示例代码http://jqueryui.com/demos/autocomplete/#combobox）
<select id="combobox">
<option value="">Select one...</option>
<option value="ActionScript">ActionScript</option>
<option value="AppleScript">AppleScript</option>

嗨Greg 感谢您的快速回复！ 我试过两种选择，但在这两种情况下，只有第一个组合框变成了一个jQuery小部件... 我已经删除了切换按钮，因为我确实不需要它... – user1264532 2012-03-13 09:05:23
适用于我：http：// jsfiddle.net/6wMz9/（注意风格丢失，按钮为空......这是因为jQuery UI CSS不存在，但你可以告诉它它工作） – 2012-03-13 14:19:54
使用类而不是ID（注意除了HTML标记是必要的，他们都得到'class =“combobox”'）http://jsfiddle.net/6wMz9/1/ – 2012-03-13 14:25:19
