The dialog box in MDUI is a very versatile component, often used to ask users for information, notify or warn users.
Only one dialog box is displayed at the same time. If the current dialog box is not closed before opening the next dialog box, then the next dialog box will be added to the queue and will be opened after the current dialog box is closed.
The buttons at the bottom of the dialog box are arranged horizontally by default. Just in <div class="mdui-dialog-actions">&You can set the buttons to be arranged vertically.code> Add class .mdui-dialog-actions-stacked 即可将按钮设置为竖直排列。
