我正在尝试使 jQueryUI 提供的小部件覆盖（“对话框”）变暗，但没有成功。我已将 jQuery 使用的 CSS 缩小到 class ui.widget-overlay，但似乎无法在我自己的样式表中覆盖 jQuery CSS。

我已经尝试过$( '.ui-widget-overlay' ).addClass( 'override' )，但没有加载我自己的样式（我已经使用 Chrome 的开发人员工具确认了这一点）。同样，$( '.ui-widget-overlay' ).removeClass( 'ui-widget-overlay' )addClass( 'override' )没有效果。

我也尝试!important在我的样式表中使用标记，再次无济于事。

我的小提琴在这里。jQueryUI 标准 CSS 内容如下：

.ui-widget-overlay { background: #aaaaaa url(images/ui-bg_flat_0_aaaaaa_40x100.png) 50% 50% repeat-x; opacity: .3;filter:Alpha(Opacity=30); }

我想用这个替换它：

.ui-widget-overlay { background: #222222 50% 50% repeat-x; opacity: .3;filter:Alpha(Opacity=30); }

HTML

        advisers</div>

<a href="#" id="industry-image">
    <div class="circle hovershadow industry industry-box-shadow">Industry</div>

<div style="clear: both;"></div>

将您添加.addClass('override')到open事件中的对话框选项中：

var commonDialogOptions = {
    autoOpen: false,
    height: "auto",
    modal: true,
    width: 700,
    open: function (event, ui) {
        $('.ui-widget-header').addClass('override');
        $('.ui-widget-header a').addClass('override');
        $('.ui-widget-overlay').addClass('override');
    }
};
