            </Setter>
        </Style>
    </UserControl.Resources>
</UserControl>

我是否需要为上述代码添加任何库

Answer 1

将您的脚本部分放入：

$(document).ready(function(){
    //your script here
});

这样的事情：

<script language="javascript">
   $(document).ready(function(){
     $('#dialog').dialog({
       dialogClass: "no-close",
       buttons: [{
         text: "Ok",
         click: function() {
           $('#dialog').dialog('close');
         }
       }]
     });
   });
</script>

这是有效的jsfiddle
