Question

我在页面上有一个手风琴控件（使用jQuery）。当我将页面的内容插入更新面板时，手风琴停止工作。如果我删除更新面板，它就会开始工作。

Why?
How can i fix this error?
Do i have to re-instantiate the accordion script/plugin, If yes then how?

  <script src="Scripts/ddaccordion.js" type="text/javascript"></script>
<script type="text/javascript">
   ddaccordion.init({

        mouseoverdelay: 200, //if revealtype="mouseover", set delay in milliseconds before header expands onMouseover
        collapseprev: true, //Collapse previous content (so only one open at any time)? true/false
        defaultexpanded: [0], //index of content(s) open by default [index1, index2, etc] [] denotes no content
        onemustopen: true, //Specify whether at least one header should be open always (so never all headers closed)
        animatedefault: false, //Should contents open by default be animated into view?

        oninit: function(headers, expandedindices) { //custom code to run when headers have initalized

        },
        onopenclose: function(header, index, state, isuseractivated) { //custom code to run whenever a header is opened or closed
            //do nothing
        }
    })

使用＜code＞pageLoad＜/code＞，它在所有部分回发时都会被调用：

$（document）.ready（）和pageLoad（）不一样

 <script type="text/javascript">
    function pageLoad()
    {
       ddaccordion.init({
            headerclass: "silverheader", //Shared CSS class name of headers group
            contentclass: "submenu", //Shared CSS class name of contents group
            revealtype: "mouseover", //Reveal content when user clicks or onmouseover the header? Valid value: "click", "clickgo", or "mouseover"
            mouseoverdelay: 200, //if revealtype="mouseover", set delay in milliseconds before header expands onMouseover
            collapseprev: true, //Collapse previous content (so only one open at any time)? true/false
            defaultexpanded: [0], //index of content(s) open by default [index1, index2, etc] [] denotes no content
            onemustopen: true, //Specify whether at least one header should be open always (so never all headers closed)
            animatedefault: false, //Should contents open by default be animated into view?
            persiststate: true, //persist state of opened contents within browser session?
            toggleclass: ["", "selected"], //Two CSS classes to be applied to the header when it s collapsed and expanded, respectively ["class1", "class2"]
            togglehtml: ["", "", ""], //Additional HTML added to the header when it s collapsed and expanded, respectively  ["position", "html1", "html2"] (see docs)
            animatespeed: "fast", //speed of animation: integer in milliseconds (ie: 200), or keywords "fast", "normal", or "slow"
            oninit: function(headers, expandedindices) { //custom code to run when headers have initalized
                //do nothing
            },
            onopenclose: function(header, index, state, isuseractivated) { //custom code to run whenever a header is opened or closed
                //do nothing
            }
        })
    }
    </script>

如果所有内容都在更新面板中，那么只需将脚本放入更新面板中即可开始工作。

Answer 3

由于手风琴的整个内容/定义都在更新面板中，因此每次更新面板更新时，您都必须重新初始化它，因为您必须获得手风琴的新副本，并且与之相关的任何事件都已消失。

我们也遇到过这个问题（使用不同的控件），我们的解决方案是将我们必须做的最起码的事情放在更新面板内，比如隐藏按钮，然后对手风琴进行编码以按下这些按钮，这样更新面板就可以在不冲洗手风琴的情况下完成任务。

我知道这是一个老帖子，但它仍然没有解决。

所以，这里有两个问题：

正如@rickschott所指出的，第一个，您需要在每次部分回发（不仅仅是第一次）后初始化插件，因为插件位于UpdatePanel内部，因此在更新UpdatePanel后它将停止工作。

当您修复该问题时，您会遇到第二个问题：页面似乎一直在刷新，但从未加载。这个问题可以被认为是ddaccordion jquery插件的一个bug。似乎它不是为了重置（或在不从头加载页面的情况下销毁和重新创建）而设计的。我做了一个变通方法，但您可能必须进行测试：

Open ddaccordion.js and find init:function(config) in it.
Remove this four lines:

document.write( <style type="text/css">
 )
document.write( . +config.contentclass+ {display: none}
 ) //generate CSS to hide contents
document.write( a.hiddenajaxlink{display: none}
 ) //CSS class to hide ajax link
document.write( </style> )

Now it will work as expected. Remember to add those 2 css classes to your css file:

.submenu { display:none }
a.hiddenajaxlink { display:none }

重要：不建议修改第三方插件，因为每次更新插件时，您可能会丢失更改。但似乎作者不再维护ddaccordion，所以也许这是一个很好的解决方案，所以我希望它能帮助其他人。
