Question

我正在尝试在Angular 8.3中编写一个简单的“是/否”确认框。

在C＃，Java，JS等中，它是单行代码：var result = MessageBox.Show("Click Me", "My Dialog", MessageBoxButtons.YesNo);

在Angular中，似乎首选的方法是使用Material Dialog。有点奏效-但它的外观或行为并不像我期望的那样。具体来说：

我想要一个弹出窗口
带有边框
以屏幕为中心
我也希望将“是”作为默认选项，并突出显示。

问：我该怎么做？

我要做的就是将此行添加到styles.css：

/* You can add global styles to this file, and also import other style files */
@import "~@angular/material/prebuilt-themes/indigo-pink.css";
