jquery ui内autocomplete中的combobox如何设置下拉层高度

现在此下拉层高度是自适应，有多少数据就列多长。想怎么设置高度，让多余的数据用滚动跳查看。

给你找的源码有这个效果的 max-height

jQuery UI Autocomplete - Scrollable results

 .ui-autocomplete { max-height: 100px; overflow-y: auto; /* prevent horizontal scrollbar / overflow-x: hidden; / add padding to account for vertical scrollbar / padding-right: 20px; } / IE 6 doesn't support max-height * we use height instead, but this forces the menu to always be this tall */ * html .ui-autocomplete { height: 100px; } 
 $(function() { var availableTags = [ "ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++", "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran", "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl", "PHP", "Python", "Ruby", "Scala", "Scheme" ]; $( "#tags" ).autocomplete({ source: availableTags }); });

When displaying a long list of options, you can simply set the max-height for the autocomplete menu to prevent the menu from growing too large. Try typing "a" or "s" above to get a long list of results that you can scroll through.

好像没有很好的办法，用div模拟把

下面的一个例子也是比较丑

<select heigth="20px;" onclick="click();" id="select1" onblur="event()"

onchange="event()">
1
2
3
4
5
6
7
8
9
10

function click(){ document.getElementById("select1").size="2"; } function event(){ document.getElementById("select1").size="1"; }
