SELECT * FROM table limit [offset,] rows | Rows Offset Offset
The limit clause can be used to force a SELECT statement to return the specified number of records. Limit accepts one or two numeric parameters. parameter must be an integer constant. Given two parameters, the first parameter specifies the offset of the first row to return the record, and the second parameter specifies the maximum number of rows to be returned. The initial record line offset is 0
' – The event is triggered when the page is loaded (including content, picture, frame, object).
' Resize ' – this event is triggered when the page size changes (for example, browser scaling).
' Scroll ' – The event is triggered when the page scrolls.
' Unload '-triggers the event when all content is deleted from the page or frame (for example, leaving a page).
There are also a variety of events, the events shown above are the most commonly used events in JavaScript, and some events may be
The reason why the inheritance mechanism cannot be dynamic is: The uniqueness of the prototype object. Instance code:Copy code code as follows:

return 0;
}
A._init = 1;
}
}
