};exportdefaultHoverText; 在这个示例中,我们创建了一个名为HoverText的组件。使用useState钩子来管理鼠标悬停的状态。 通过定义handleMouseEnter和handleMouseLeave两个事件处理函数,我们可以在鼠标进入和离开元素时更新悬停状态。 在组件的返回值中,我们将元素作为悬停触发区域,并根据isHovered状态来决定是否显示文本。 当...

React Native有一些特定的附加样式属性,如borderRadius用于圆角,flex用于弹性盒布局 内联样式 vs. 样式表 你可以通过内联样式或StyleSheet来为 React Native 组件应用样式。 内联样式直接用作组件的style属性中的JavaScript对象: <Text style={{fontSize: 20, color: 'blue'}}>Hello LogRocket!</Text> StyleSheet用于...

};exportdefaultHoverText; 在这个例子中,我们使用了useState钩子来创建一个状态变量isHovered和一个设置函数setIsHovered。当鼠标进入元素时,onMouseEnter事件触发器会设置isHovered为true,而当鼠标离开时,onMouseLeave事件触发器将其设置为false。条件渲染{isHovered && This is some extra text.}确保只有在isHovered为...
然后,我们在div元素上使用onMouseEnter和onMouseLeave事件处理程序来更新isHovered状态变量。 接下来,使用useEffect挂钩来处理在组件挂载和卸载时的副作用。在这种情况下,我们可以使用useEffect挂钩来在控制台上打印出当前的isHovered状态: 代码语言:txt 复制 import React, { useState, useEffect } from 'react'; ...
