说丑不丑，说好看也不好看的路灯
1.先看效果
2.源代码
import React, { useState, useEffect } from 'react'
export default function StreetLamp() {
const [isNight, setIsNight] = useState(false)
const [isLampOn, setIsLampOn] = useState(false)
const [isAutoMode, setIsAutoMode] = useState(true)
useEffect(() => {
const checkTime = () => {
const currentHour = new Date().getHours()
setIsNight(currentHour >= 18 || currentHour < 6)
}
checkTime()
const interval = setInterval(checkTime, 60000) // Check every minute
return () => clearInterval(interval)
}, [])
useEffect(() => {
if (isAutoMode) {
setIsLampOn(isNight)
}
}, [isNight, isAutoMode])
const toggleLamp = () => {
if (isAutoMode) {
setIsAutoMode(false)
}
setIsLampOn(!isLampOn)
}
return (
Interactive Street Lamp
Auto
type="checkbox"
checked={isAutoMode}
onChange={() => setIsAutoMode(!isAutoMode)}
/>
{/* Lamp post */}
{/* Lamp head */}
{/* Light beam */}
d="M30 20 L10 100 H90 L70 20" fill={isLampOn ? "rgba(255, 255, 200, 0.2)" : "transparent"} > attributeName="opacity" values={isLampOn ? "0.2;0.5;0.2" : "0;0"} dur="4s" repeatCount="indefinite" />
{/* Lamp light */}
cx="50" cy="20" r="10" fill={isLampOn ? "#FFFFA0" : "#888"} > attributeName="opacity" values={isLampOn ? "0.7;1;0.7" : "1;1"} dur="4s" repeatCount="indefinite" />
{/* Sun/Moon */}
className={`absolute top-4 right-4 w-12 h-12 rounded-full transition-all duration-1000 ${
isNight ? "bg-gray-300" : "bg-yellow-400"
}`}
>
)
}
3.同时还需要这段css代码
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
.switch input {
opacity: 0;
width: 0;
height: 0;
}
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
transition: .4s;
}
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
transition: .4s;
}
input:checked + .slider {
background-color: #2196F3;
}
input:checked + .slider:before {
transform: translateX(26px);
}
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
