原文:jquery ui中 accordion的问题及我的解决方法
jquery有一套所谓的ui组件，很不错的。如果有兴趣的朋友，可以参考http://jqueryui.com/
但其中的accordion，我使用的时候发现一些问题。如果按照demo那样，写一些静态内容，倒也正常。但如果每个面板里面的内容是动态绑定的，则会发生高度变小，然后出现滚动条的诡异现象

开始的时候，看起来不错
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
但只要缩放几次，就会出现下面这样的情况
发现了吗，div的高度会缩小，然后出现滚动条。而且更加神奇的是，它会逐渐变小，小到一定程度之后，又会还原。
尝试过他所有的参数，也没有找到很好的方法，实在也是不解，难道这么明显的问题别人就没有遇到过。
我的解决方法倒也干脆，既然不好用，那就自己动手写一个，其实也没有什么大不了的。当然，我写的这个和accordion不完全一样，但更符合我自己的需要，而且简便易行
脚本代码
/// 这个脚本用来处理所有的widget行为。
/// 作者：陈希章 $(function() { $("div.widget").each(function() {
var w = $(this);
var d = w.find("div.details");
var h = parseInt(d.attr("offsetHeight")) + 10;
d.css("height", h); var autoOpen = w.attr("autoOpen");
if (autoOpen != null && autoOpen == "false") {
d.fadeOut("fast");
//只有明确地设置了不自动打开，才隐藏起来
}
else {
//如果设置了一个action，表示要异步加载
var a = d.attr("action");
if (a != null) {
d.empty();
$("<img src='images/loading.gif' />").appendTo(d);
d.load(a);
}
}
}); $("div.widget>div.title").click(function() {
var t = $(this);
var d = t.next("div.details");
t.children(".icon").toggleClass("icon2"); var display = d.css("display");
if (display == "none") {
d.fadeIn("slow", function() {
var a = d.attr("action");
if (a != null) {
d.empty();
$("<img src='images/loading.gif' />").appendTo(d);
d.load(a);
}
});
}
else
d.fadeOut("fast"); });
});
