jquery - jqGrid/ui-widget-overlay 阻止整个页面上的所有按钮和选项卡事件

Question

我正在将 redmond themeroller 与 jqGrid 一起使用。文件 jquery-ui-1.8.16.custom.css 具有此覆盖层。

/* Overlays */
.ui-widget-overlay { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

我认为它应该在网格上制作一个覆盖层来进行样式设计。但它似乎覆盖了我的整个页面，虽然网格本身仍然有鼠标事件，但页面的其余部分(包括网格的寻呼机/导航器部分)没有任何鼠标事件，并且按钮没有响应点击次数。网格之外的选项卡 - 也没有单击事件。即使该选项卡之外的选项卡(主要、用户...)也没有事件。如果我注释掉 ui-widget-overlay，那么所有按钮和选项卡都会再次工作，但屏幕的颜色会变浅，并且网格中的交替行颜色每行都变为白色。为什么会出现这种情况？

ui-widget-overlay 是一个通用的 jquery ui 样式类。它会在您应用此类的元素上创建一个覆盖层。

要在 jQgrid 上创建覆盖，您应该使用类jqgrid-overlay。这将阻止网格上默认的鼠标单击事件。
调出叠加层:

$("#lui_"+gridid).show();  

并隐藏它
$("#lui_"+gridid).hide();
