What is the usage of layer.alert in Layui?

The layer.alert function in Layui is utilized to pop up an alert box on the page, informing the user of a certain message.

Here is how to use it:

layer.alert('内容', options, callback);

‘Content’ refers to the text information that needs to be displayed in the alert box.

Options are optional parameters used to set the configuration of the alert box. Commonly used configuration items include:

1. Icon: Choose an icon to display, options include 0 (default exclamation icon), 1 (checkmark icon), or 2 (error icon).
2. Title: The default title is set to ‘Prompt’.
3. Default button settings are set to ‘OK’.
4. btnAlign: Specify the alignment of the button, defaulting to ‘c’ (center align).
5. closeBtn: 0 by default (not visible), can be set to show the close button.

The callback is a function that is triggered after clicking the confirm button, allowing for the processing of user actions.
