如果我提出基本问题，请原谅我。我是javascript的新手..
我正在尝试创建一个对话框，动态创建一个复选框列表以显示在此对话框中，每个用户请求显示一个复选框。 如果复选框的数量从定义的宽度增加，则对话框应该有一个滚动条以滚动。 我能够创建对话框（虽然不是一个非常优雅的解决方案），但有一个问题......
如果我尝试按住滚动条并移动它，则Windows资源管理器9中出现的对话框有一个不移动的滚动条。在Firefox上工作得很好..
感谢任何帮助..

我在这个代码片段中发现了一些语法错误（参见注释）。我不是说它会解决滚动问题，但它们应该被修复了......
cbFilterDivRef = dojo.create("div",{
id: "filterDivID",
style: {"overflow": "scroll",
"overflow": "scroll", //remove duplicate
"width": "350px",
"height": "400px"
}, //remove comma after bracket
},
dojo.byId("hiddenDiv"), "first");
