示例

下面的示例演示三个按三种不同方式响应单击的按钮。The following example shows three buttons that respond to clicks in three different ways.

  • 悬停-当用户将鼠标悬停在按钮上时, 第一个按钮更改颜色。Hover - the first button changes colors when the user hovers with the mouse over the button.

  • 按下-第二个按钮要求在鼠标指针位于按钮上时按下鼠标。Press - the second button requires that the mouse be pressed while the mouse pointer is in the button.

  • Release-第三个按钮不会重置按钮的背景色, 直到在按钮中按下并释放鼠标。Release - the third button does not reset the background color of the buttons until the mouse is pressed and released in the button.
