jquery scrollpane ms ajax updatepanel 回发后不起作用

发布于 2024-08-07 22:10:53 字数 6198 浏览 9 评论 0原文

我收到了一个网站的新设计，设计者在设计中使用了jquery。我正在将设计实现到 ASP.NET Ajax 应用程序中。

但我遇到了一个问题。我有一个带有更新面板和菜单的页面。单击菜单项时，用户控件将动态加载到更新面板上的占位符中。这使得页面没有完全刷新，而只是更新面板。

现在，用户控件中的内容包含一个延伸到窗口最大高度的滚动窗格。第一次运行良好，但是当单击菜单项并加载新的用户控件时，该控件的内容包含相同的滚动窗格。高度不会扩展到窗口的最大高度，然后仅使用所需的高度。当我不包含 jquery 文件时，也会发生同样的事情，因此它必须对 jscript 库执行某些操作。

页面中使用的脚本：

scripts/jquery.js
jquery.watermark.js
scripts/jquery.customSelect.js
scripts/jquery.easing.js
scripts/jquery.logger.js
scripts/jquery.sizes.min.js
scripts/jquery.mousewheel.js
scripts/jquery.em.js
scripts/jquery.core.js
scripts/jquery.accordion.js
scripts/jquery.tabs.js
scripts/jquery.scroll.js
scripts/jquery.datepick.js
scripts/jquery.datepick-nl.js
scripts/jquery.scripts.js

加载主页的页面的主要代码：

<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div id="container">

<div id="logo"></div>
    <uc2:Menu ID="ucMenu" runat="server" />
    <uc3:Kruimelpad ID="ucKruimelpad" runat="server" />
    <asp:UpdatePanel ID="upMain" runat="server" UpdateMode="Always">
    <ContentTemplate>
 <asp:PlaceHolder ID="phMain" runat="server" />
 </ContentTemplate>
 </asp:UpdatePanel>
<div id="sideBar"> 
   <uc1:Login ID="ucLogin" runat="server" />
</div>
<div class="clearboth"></div>
</div>

<uc4:Footer ID="ucFooter" runat="server" />

</div>
</form>
</body>
</html>

用户控件的主要代码：

<div class="editMenu">  
</div> 
 <div id="content" class="orange-bar"> 
   <div id="contentVlak" class="scroll_pane">
<h1><asp:Label ID="lblNoAccount" runat="server" Text="<%$ Resources:Login, no_account %>"></asp:Label></h1>

<p><asp:Label ID="lblMainText" runat="server" Text="<%$ Resources:Login, main_text %>"></asp:Label>&nbsp;<asp:LinkButton 
                    ID="lbAccountAanvragen" runat="server" 
                    Text="<%$ Resources:Login, demo_account_aanvragen %>" 
                    onclick="lbAccountAanvragen_Click"></asp:LinkButton>.</p>
            </div>
    </div>

CSS 代码：

 #content {
 background: url(../images/contentBg.png) repeat-y left top;
 position: relative;
 top: 58px;
 margin: 0px 0px 0px 11px !important;
 width: 886px;
 padding: 20px 20px 10px 20px;
 }

  #contentVlak {
  width: 676px;
  height:100%;
  padding: 0px 20px;
  }

   #contentVlak p {
   line-height: 20px;
   margin-bottom: 10px;
   font-size: 11.5px;
   }

   #contentVlak a {
   font-weight: bold;
   text-decoration: none;
   }

    #contentVlak a:hover {
    text-decoration: underline;
    }


/* Scrollpane styles */

.scroll_pane {
 overflow: auto;
}

.jScrollPaneContainer {
 position: relative;
 overflow: hidden;
 z-index: 1;
}

.jScrollPaneTrack {
 position: absolute;
 cursor: pointer;
 right: 0;
 top: 0;
 height: 100%;
 background: url(../images/scrollTrack.png) repeat-y left top;
}

.jScrollPaneDrag {
 position: absolute;
 background: #666;
 cursor: pointer;
 overflow: hidden;
 height: 20px !important;
 width: 20px;
 background: url(../images/scrollPane.png) no-repeat left top;
}
.jScrollPaneDragTop {
 position: absolute;
 top: 0;
 left: 0;
 overflow: hidden;
}
.jScrollPaneDragBottom {
 position: absolute;
 bottom: 0;
 left: 0;
 overflow: hidden;
}
a.jScrollArrowUp {
 display: block;
 position: absolute;
 z-index: 1;
 top: 0;
 right: 0;
 text-indent: -2000px;
 overflow: hidden;
 background: url(../images/scrollUp.png) no-repeat left top;
 height: 16px;
 width: 16px;
}


a.jScrollArrowDown {
 display: block;
 position: absolute;
 z-index: 1;
 bottom: 0;
 right: 0;
 text-indent: -2000px;
 overflow: hidden;
 background: url(../images/scrollDown.png) no-repeat left top;
 height: 16px;
 width: 16px;
}

我做错了什么？

调整块大小的代码：

function resizeBlock(object) {

var windowHeight = $(window).height();
var start = object.offset().top;
var margin = object.margin().bottom + object.margin().top;
var padding = object.padding().bottom + object.padding().top;

var totalHeight = windowHeight - start - padding - 9;

object.height(totalHeight);

// Hoogtes van scroll-ding fixen
object.find(".scroll_pane").height(totalHeight);
object.find(".jScrollPaneContainer").height(totalHeight);
object.find(".jScrollPaneTrack").height(totalHeight);
object.find(".jScrollPaneDrag").height(totalHeight - 32);

// Object opnieuw toevoegen 
$(".scroll_pane").jScrollPane({ showArrows: true, scrollbarWidth: 16 });
}

$(document).ready(function () {

    // Functie zie hierboven
    resizeBlock($("#content"));
    $(".scroll_pane").jScrollPane({ showArrows: true, scrollbarWidth: 16 });

    $(window).resize(function() {
        resizeBlock($("#content"));
    });


    // Custom selectboxes

    if($(".default-usage-select").length > 0) {
        $(".default-usage-select").selectbox();
    }


    // Watermarks op homepage

    if($("#relatiecode").length > 0) {
        $("#relatiecode").Watermark("relatiecode", "#808285");
    }

    if($("#wachtwoord").length > 0) {
        $("#wachtwoord").Watermark("wachtwoord", "#808285");
    }

    // Accordion box

    if($(".accordion").length > 0) {
        $('.accordion').accordion({ 
            header: '.accordionTrigger',
            autoheight: true,
            animate: '100'
        });

        if($(".accordionTrigger").hasClass("selected")) {
            $("#accordionLastTrigger").addClass  ("activeLastTrigger");
        }
    }

    // Tabbladen 

    if($("#tabContainer").length > 0) {
        $('#tabContainer > ul').tabs();
    }

    // IE 6 Hover fix voor menu's

    if (jQuery.browser.msie) {
        if(parseInt(jQuery.browser.version) == 6) {
        $('ul li').hover(function() {
            $(this).addClass('ie6hover');
        }, function() {
            $(this).removeClass('ie6hover');
        });  
    }

} 
});if (typeof(Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();

I have received a new design for a website and in the design the designer used jquery. I'm implementing the design no into an ASP.NET Ajax application.

But I ran into a problem. I have a page with an update panel and a menu. When a menu item is clicked a user control is loaded dynamically into a placeholder on the update panel. This makes that the page is not totally refreshed but only the update panel.

Now the content in the user control contains a scrollpane that extends to the maximum height of the window. The first time that runs fine, but when a menu item is clicked and the new user control is loaded which has content witch includes the same scrollpane. The height isn't extended to the maximum height of the window, it then only uses the height it needs. The same thing happens when I don't include the jquery files so it has to do something with the jscript library.

The scripts that are used in the page:

scripts/jquery.js
jquery.watermark.js
scripts/jquery.customSelect.js
scripts/jquery.easing.js
scripts/jquery.logger.js
scripts/jquery.sizes.min.js
scripts/jquery.mousewheel.js
scripts/jquery.em.js
scripts/jquery.core.js
scripts/jquery.accordion.js
scripts/jquery.tabs.js
scripts/jquery.scroll.js
scripts/jquery.datepick.js
scripts/jquery.datepick-nl.js
scripts/jquery.scripts.js

Main code of the page that loads the main page:

<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div id="container">

<div id="logo"></div>
    <uc2:Menu ID="ucMenu" runat="server" />
    <uc3:Kruimelpad ID="ucKruimelpad" runat="server" />
    <asp:UpdatePanel ID="upMain" runat="server" UpdateMode="Always">
    <ContentTemplate>
 <asp:PlaceHolder ID="phMain" runat="server" />
 </ContentTemplate>
 </asp:UpdatePanel>
<div id="sideBar"> 
   <uc1:Login ID="ucLogin" runat="server" />
</div>
<div class="clearboth"></div>
</div>

<uc4:Footer ID="ucFooter" runat="server" />

</div>
</form>
</body>
</html>

main code of the user control:

<div class="editMenu">  
</div> 
 <div id="content" class="orange-bar"> 
   <div id="contentVlak" class="scroll_pane">
<h1><asp:Label ID="lblNoAccount" runat="server" Text="<%$ Resources:Login, no_account %>"></asp:Label></h1>

<p><asp:Label ID="lblMainText" runat="server" Text="<%$ Resources:Login, main_text %>"></asp:Label> <asp:LinkButton 
                    ID="lbAccountAanvragen" runat="server" 
                    Text="<%$ Resources:Login, demo_account_aanvragen %>" 
                    onclick="lbAccountAanvragen_Click"></asp:LinkButton>.</p>
            </div>
    </div>

CSS code:

 #content {
 background: url(../images/contentBg.png) repeat-y left top;
 position: relative;
 top: 58px;
 margin: 0px 0px 0px 11px !important;
 width: 886px;
 padding: 20px 20px 10px 20px;
 }

  #contentVlak {
  width: 676px;
  height:100%;
  padding: 0px 20px;
  }

   #contentVlak p {
   line-height: 20px;
   margin-bottom: 10px;
   font-size: 11.5px;
   }

   #contentVlak a {
   font-weight: bold;
   text-decoration: none;
   }

    #contentVlak a:hover {
    text-decoration: underline;
    }


/* Scrollpane styles */

.scroll_pane {
 overflow: auto;
}

.jScrollPaneContainer {
 position: relative;
 overflow: hidden;
 z-index: 1;
}

.jScrollPaneTrack {
 position: absolute;

}

.jScrollPaneDrag {

 overflow: hidden;
 height: 20px !important;
 width: 20px;
 background: url(../images/scrollPane.png) no-repeat left top;
}
.jScrollPaneDragTop {
 position: absolute;
 top: 0;
 left: 0;
 overflow: hidden;
}
.jScrollPaneDragBottom {
 position: absolute;
 bottom: 0;
 left: 0;
 overflow: hidden;

 text-indent: -2000px;
 overflow: hidden;
 background: url(../images/scrollDown.png) no-repeat left top;
 height: 16px;
 width: 16px;
}

What am I doing wrong?

Code for resizing the block:

function resizeBlock(object) {

var windowHeight = $(window).height();
var start = object.offset().top;
var margin = object.margin().bottom + object.margin().top;
var padding = object.padding().bottom + object.padding().top;

var totalHeight = windowHeight - start - padding - 9;

object.height(totalHeight);

// Hoogtes van scroll-ding fixen
object.find(".scroll_pane").height(totalHeight);
object.find(".jScrollPaneContainer").height(totalHeight);
object.find(".jScrollPaneTrack").height(totalHeight);
object.find(".jScrollPaneDrag").height(totalHeight - 32);

// Object opnieuw toevoegen 
$(".scroll_pane").jScrollPane({ showArrows: true, scrollbarWidth: 16 });
}

$(document).ready(function () {

    // Functie zie hierboven
    resizeBlock($("#content"));
    $(".scroll_pane").jScrollPane({ showArrows: true, scrollbarWidth: 16 });

    $(window).resize(function() {
        resizeBlock($("#content"));
    });


    // Custom selectboxes

    if($(".default-usage-select").length > 0) {
        $(".default-usage-select").selectbox();
    }


    // Watermarks op homepage

    if($("#relatiecode").length > 0) {
        $("#relatiecode").Watermark("relatiecode", "#808285");
    }

    if($("#wachtwoord").length > 0) {
        $("#wachtwoord").Watermark("wachtwoord", "#808285");
    }

    // Accordion box

    if($(".accordion").length > 0) {
        $('.accordion').accordion({ 
            header: '.accordionTrigger',
            autoheight: true,
            animate: '100'
        });

        if($(".accordionTrigger").hasClass("selected")) {
            $("#accordionLastTrigger").addClass  ("activeLastTrigger");
        }
    }

    // Tabbladen 

    if($("#tabContainer").length > 0) {
        $('#tabContainer > ul').tabs();
    }

    // IE 6 Hover fix voor menu's

    if (jQuery.browser.msie) {
        if(parseInt(jQuery.browser.version) == 6) {
        $('ul li').hover(function() {
            $(this).addClass('ie6hover');
        }, function() {
            $(this).removeClass('ie6hover');
        });  
    }

} 
});if (typeof(Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();

发生这种情况的原因是控件本质上被重新绘制到浏览器，并且您为滚动窗格初始化的 jQuery 并未通过重新绘制进行初始化。

您可以利用 JavaScript 函数来重新初始化 jQuery 代码。我将举一个简单的例子，确保您的页面上有 ScriptManager（您应该因为它是更新面板......）...

<script type="text/javascript">
    function pageLoad() {
        if (!Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack()) {
            Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler);
        }
    }
    function endRequestHandler(sender, args) {
        //Redo the scroll pane jQuery Initialization here...
    }

</script>

This is occurring because the control is essentially being repainted to the browser and the jQuery that you initialized for the scroll-pane was not initialized with the repainting.

You can tap into a javascript function that allows you to re-initalize the jQuery code. I'll grab a quick example, make sure you have the ScriptManager on your page (you should since its an Update Panel...)...

<script type="text/javascript">
    function pageLoad() {
        if (!Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack()) {
            Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler);
        }
    }
    function endRequestHandler(sender, args) {
        //Redo the scroll pane jQuery Initialization here...
    }

</script>

谢谢 RSolberg，你的解决方案对我有用。我正在为 Apple 设备使用 JScrollpane。它适用于更新面板。这是我更新的代码：

    if ((navigator.userAgent.indexOf('AppleWebKit') != -1) || (navigator.userAgent.indexOf('iPhone') != -1) || (navigator.userAgent.indexOf('iPod') != -1) || (navigator.userAgent.indexOf('iPad') != -1) || (navigator.userAgent.indexOf('android') != -1) || (navigator.userAgent.indexOf('BlackBerry') != -1)) {
        $('#<%=iWrapper1.clientID%>').jScrollPane();
        $('#<%=iWrapper2.clientID%>').jScrollPane();
        $('.videoDisplay').jScrollPane();
    }


    if (navigator.userAgent.indexOf("MSIE") != -1)
        window.attachEvent("onload", pageLoad)
    else
        window.addEventListener("load", pageLoad, false);


    function pageLoad() {
        if (!Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack()) {
            Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler);

        }
    }

    function endRequestHandler(sender, args) {
         if ((navigator.userAgent.indexOf('AppleWebKit') != -1) || (navigator.userAgent.indexOf('iPhone') != -1) || (navigator.userAgent.indexOf('iPod') != -1) || (navigator.userAgent.indexOf('iPad') != -1) || (navigator.userAgent.indexOf('android') != -1) || (navigator.userAgent.indexOf('BlackBerry') != -1)) {
            $('#<%=iWrapper1.clientID%>').jScrollPane();
            $('#<%=iWrapper2.clientID%>').jScrollPane();
            $('.videoDisplay').jScrollPane();
        }
    }

Thanks RSolberg, your solution worked for me..I am using JScrollpane for Apple devices..and it works with update panel. Here is my updated code:

    if ((navigator.userAgent.indexOf('AppleWebKit') != -1) || (navigator.userAgent.indexOf('iPhone') != -1) || (navigator.userAgent.indexOf('iPod') != -1) || (navigator.userAgent.indexOf('iPad') != -1) || (navigator.userAgent.indexOf('android') != -1) || (navigator.userAgent.indexOf('BlackBerry') != -1)) {
        $('#<%=iWrapper1.clientID%>').jScrollPane();
        $('#<%=iWrapper2.clientID%>').jScrollPane();
        $('.videoDisplay').jScrollPane();
    }


    if (navigator.userAgent.indexOf("MSIE") != -1)
        window.attachEvent("onload", pageLoad)
    else
        window.addEventListener("load", pageLoad, false);


    function pageLoad() {
        if (!Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack()) {
            Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler);

        }
    }

    function endRequestHandler(sender, args) {
         if ((navigator.userAgent.indexOf('AppleWebKit') != -1) || (navigator.userAgent.indexOf('iPhone') != -1) || (navigator.userAgent.indexOf('iPod') != -1) || (navigator.userAgent.indexOf('iPad') != -1) || (navigator.userAgent.indexOf('android') != -1) || (navigator.userAgent.indexOf('BlackBerry') != -1)) {
            $('#<%=iWrapper1.clientID%>').jScrollPane();
            $('#<%=iWrapper2.clientID%>').jScrollPane();
            $('.videoDisplay').jScrollPane();
        }
    }
