我在绝对位置上有4条。由于每5秒增加一个类，该函数正在扩展并变得可见。

我知道我可以将scaleX（50）的宽度更改为50％，但这会占用更多的浏览器资源。

显然，我还必须通过Codepen链接显示我的代码，所以我们开始...

在Chrome中将轮廓设置为透明对我来说很有效

{
    xtype: "combobox",
    id: "rolesBox",
    alias: "widget.rolesbox",
    store: Ext.create("MyApp.store.users.Roles"),
    listeners: {
        afterRender: function (combobox) {
            this.select(combobox.store.getData().items[0]);
        }
    }
}
