记得之前在别的网站上看到这个喜庆的春节灯笼效果,觉得非常吸引人。虽然网上有一些现成的API可以直接实现,比如这个,但使用后我发现两个问题:一是手机端访问时灯笼没有自适应,二是灯笼上的“春节快乐”四个字不能自定义。
原文可查看效果:
一,引入使用
距离春节还有不到90天,赶紧试试吧!将以下JS在您的页面直接引入即可。
<!-- 将以下js放入您的页面即可。text为灯笼文字,默认:新年快乐 -->
<script src="https://www.vae.zhangweicheng.xyz/web/denglong.js?text=好好学习"> </script>
二,完整JS代码
// 张苹果博客:https://zhangpingguo.com/
// 创建并添加元素
function createDengContainer() {
const container = document.createElement('div');
container.className = 'deng-container';
// 从当前脚本的 URL 获取参数
const scriptSrc = document.currentScript.src;
const urlParams = new URLSearchParams(scriptSrc.split('?')[1]); // 获取 '?'
const customText = urlParams.get('text'); // 获取参数名为'text'的值
// 将获取的文本分割为字符数组,如果没有提供文本,则使用默认的“新年快乐”
const texts = customText ? customText.split('') : ['新', '年', '快', '乐'];
texts.forEach((text, index) => {
const box = document.createElement('div');
box.className = `deng-box deng-box${index + 1}`;
const deng = document.createElement('div');
deng.className = 'deng';
const xian = document.createElement('div');
xian.className = 'xian';
const dengA = document.createElement('div');
dengA.className = 'deng-a';
const dengB = document.createElement('div');
dengB.className = 'deng-b';
const dengT = document.createElement('div');
dengT.className = 'deng-t';
dengT.textContent = text;
dengB.appendChild(dengT);
dengA.appendChild(dengB);
deng.appendChild(xian);
deng.appendChild(dengA);
const shuiA = document.createElement('div');
shuiA.className = 'shui shui-a';
const shuiC = document.createElement('div');
shuiC.className = 'shui-c';
const shuiB = document.createElement('div');
shuiB.className = 'shui-b';
shuiA.appendChild(shuiC);
shuiA.appendChild(shuiB);
deng.appendChild(shuiA);
box.appendChild(deng);
container.appendChild(box);
});
document.body.appendChild(container);
}
// 添加CSS样式
function addStyles() {
const style = document.createElement('style');
style.type = 'text/css';
style.textContent = `
