这里是我的代码，有什么不对吗？
它似乎不显示焦点上的列表，我还是要按一个键之前，它显示列表

<input type="text" id="id">
解决方法
看起来你正在将focus()处理程序附加到匿名函数，而不是文本框。
尝试这个：
<script type="text/javascript">
$(function() {
$('#id').autocomplete({
source: ["ActionScript",/* ... */
],minLength: 0
}).focus(function(){
// The following works only once.
// $(this).trigger('keydown.autocomplete');
// As suggested by digitalPBK,works multiple times
$(this).data("autocomplete").search($(this).val());
});
});
</script>
