我在ASP.NETMVC3应用程序中使用jQuery模式对话框.它工作正常，只是右上角没有显示关闭按钮.我怎么才能加上这个呢？
$("#dialog-modal").dialog({
modal: true,
autoOpen: false,
buttons: {
Ok: function () {
$(this).dialog("close");
}
}
});
In the upper right corner of the dialog, mouse over where the button should be, and see rather or not you get some effect (the button hover). Try clicking it and seeing if it closes. If it does close, then you're just missing your image sprites that came with your package download.
