上一篇是背景动态线条
这里有两个例子,可以试试
不多说直接上代码:
一、
<!-- 爱心特效 --> <script type="text/javascript"> (function(window,document,undefined){ var hearts = []; window.requestAnimationFrame = (function(){ return window.requestAnimationFrame || window.webkitRequestAnimationFrame || window.mozRequestAnimationFrame || window.oRequestAnimationFrame || window.msRequestAnimationFrame || function (callback){ setTimeout(callback,1000/60); } })(); init(); function init(){ css(".heart{width: 10px;height: 10px;position: fixed;background: #f00;transform: rotate(45deg);-webkit-transform: rotate(45deg);-moz-transform: rotate(45deg);}.heart:after,.heart:before{content: '';width: inherit;height: inherit;background: inherit;border-radius: 50%;-webkit-border-radius: 50%;-moz-border-radius: 50%;position: absolute;}.heart:after{top: -5px;}.heart:before{left: -5px;}"); attachEvent(); gameloop(); } function gameloop(){ for(var i=0;i<hearts.length;i++){ if(hearts[i].alpha <=0){ document.body.removeChild(hearts[i].el); hearts.splice(i,1); continue; } hearts[i].y--; hearts[i].scale += 0.004; hearts[i].alpha -= 0.013; hearts[i].el.style.cssText = "left:"+hearts[i].x+"px;top:"+hearts[i].y+"px;opacity:"+hearts[i].alpha+";transform:scale("+hearts[i].scale+","+hearts[i].scale+") rotate(45deg);background:"+hearts[i].color; } requestAnimationFrame(gameloop); } function attachEvent(){ var old = typeof window.onclick==="function" && window.onclick; window.onclick = function(event){ old && old(); createHeart(event); } } function createHeart(event){ var d = document.createElement("div"); d.className = "heart"; hearts.push({ el : d, x : event.clientX - 5, y : event.clientY - 5, scale : 1, alpha : 1, color : randomColor() }); document.body.appendChild(d); } function css(css){ var style = document.createElement("style"); style.type="text/css"; try{ style.appendChild(document.createTextNode(css)); }catch(ex){ style.styleSheet.cssText = css; } document.getElementsByTagName('head')[0].appendChild(style); } function randomColor(){ return "rgb("+(~~(Math.random()*255))+","+(~~(Math.random()*255))+","+(~~(Math.random()*255))+")"; } })(window,document); </script>
把这个代码加入到博客侧边公告栏里 (要申请js权限):
二、
这一种是带文字的效果如下:
上代码:首先是css代码:
body{ position:relative; } .img {width: 20px;height: 20px;opacity: 1;position: absolute;z-index: 100000;transition: 1s;} .left,.right {width: 10px;height: 10px;border-radius: 100%;position: absolute;} .right {right: 0;} .under {width: 10px;height: 10px;position: absolute;top: 5px;left: 5px;transform: rotate(45deg)} .text {width: 50px;font-size: 10px;line-height: 1;position: absolute;top: -1em;left: -15px;text-align: center;}
直接复制到css代码框里面:
然后是js代码:
<script> // 点击出的文字数组,可自行添加,不要太多哦 text = ["你好呀~", "点我呀~", "啦啦啦~", "哎呀呀~", "求关注~", "帅哥美女~", "哦~", "咦~"]; // 计数 var count = 0; // 鼠标按下事件 document.body.onmousedown = function (e) { // 获取鼠标点击位置 var x = event.pageX - 18; var y = event.pageY - 30; // 分别创建所需要的元素节点 var img = document.createElement("div"); var left = document.createElement("div"); var right = document.createElement("div"); var under = document.createElement("div"); var txt = document.createElement("div"); // 通过随机数从文字数组中获取随机下标的文字 var textNode = document.createTextNode(text[parseInt(Math.random() * text.length)]); // 文字添加到txt节点中 txt.appendChild(textNode); img.className = "img" + " " + "img" + count; left.className = "left"; right.className = "right"; under.className = "under"; txt.className = "text"; img.style.top = y + "px"; img.style.left = x + "px"; // 将创建的元素添加到容器中 img.appendChild(left); img.appendChild(right); img.appendChild(under); img.appendChild(txt); document.body.appendChild(img); // 获取随机颜色 var color = "rgb(" + parseInt(Math.random() * 255) + "," + parseInt(Math.random() * 255) + "," + parseInt(Math.random() * 255) + ")"; txt.style.color=color; for (var i = 0; i < 3; i++) { img.children[i].style.background = color; } } // 鼠标抬起事件 document.body.onmouseup = function () { document.getElementsByClassName("img" + count)[0].style.transform = "scale(0.5)"; document.getElementsByClassName("img" + count)[0].style.transform = "translateY(-40px)"; document.getElementsByClassName("img" + count)[0].style.opacity = "0"; count++; } </script>
把js代码复制到博客侧边栏公告(要开通js权限)如图:
我用的是第一种方法;第二种我用的有一点小bug所以我选了第一种朋友们可以根据自己的效果选择
有人更好的效果和方法就和我分享一下子感谢各位老铁
有错误的地方还请纠正我会修改
