jquery.tinyscrollbar 弹出滚动条不工作

Question

• 原始演示 http://jsfiddle.net/anglimass/NVTzx/9/
• 更新的演示(实际演示了问题)http://jsfiddle.net/NVTzx/16/

请点击“查看全部”然后弹出一个。出现弹出窗口，但滚动条不起作用。

JavaScript

$(document).ready(function(){
    $('#scrollbar1').tinyscrollbar();    
});

//SETTING UP OUR POPUP
//0 means disabled; 1 means enabled;
var popupStatus = 0;

//loading popup with jQuery magic!
function loadPopup(){
    //loads popup only if it is disabled
    if(popupStatus==0){
        jQuery("#backgroundPopup").css({
            "opacity": "0.7"
        });
        jQuery("#backgroundPopup").fadeIn("slow");
        jQuery("#popupContact").fadeIn("slow");
        popupStatus = 1;
    }
}

//disabling popup with jQuery magic!

    //disables popup only if it is enabled
    if(popupStatus==1){
        jQuery("#backgroundPopup").fadeOut("slow");
        jQuery("#popupContact").fadeOut("slow");
        popupStatus = 0;
    }
}

//centering popup

    });
    //only need force for IE6

    jQuery("#backgroundPopup").css({

Answer 1

JavaScript 错误是 Uncaught TypeError: Cannot read property 'scrollHeight' of undefined at jquery.tinyscrollbar.js:54。看着the source , 它试图找到 scrollHeight 与

oContent[options.axis] = oContent.obj[0]['scroll'+ sSize];

但是 oContent 被定义为

var oContent = { obj: $('.overview', root) };

class="overview" 标记中没有元素，因此脚本失败。

我建议遵循您似乎拥有的网站上的示例 downloaded the script from ，特别是 基本滚动条的 HTML。该脚本需要您在演示中没有的标记。
