我使用以下代码显示jQuery UI对话框:

var $dialog = $('<div></div>')
.text(msg)
.dialog({
    autoOpen: false,
    height: 140,
    modal: true,
    title: "Confirm",
    buttons: {
        "Yes": function() {
            $(this).dialog('close');
        },
        "Cancel": function() {
            $(this).dialog('close');
        }
    }
});
$dialog.dialog('open');

但是,按钮没有样式.我注意到为按钮生成的HTML是:

<div class="ui-dialog-buttonset">
    <button>Yes</button>
    <button>Cancel</button>
</div>

从jQuery UI演示中它是:

<div class="ui-dialog-buttonset">
    <button class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button" aria-disabled="false"><span class="ui-button-text">Ok</span></button>
    <button class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button" aria-disabled="false"><span class="ui-button-text">Cancel</span></button>
</div>

即缺少CSS样式.你知道为什么吗？
