上一篇是背景動態線條
這里有兩個例子,可以試試
不多說直接上代碼:
一、
<!-- 愛心特效 --> <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>
把這個代碼加入到博客側邊公告欄里 (要申請js權限):

二、
這一種是帶文字的效果如下:

上代碼:首先是css代碼:
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;}
直接復制到css代碼框里面:

然后是js代碼:
<script>
// 點擊出的文字數組,可自行添加,不要太多哦
text = ["你好呀~", "點我呀~", "啦啦啦~", "哎呀呀~", "求關注~", "帥哥美女~", "哦~", "咦~"];
// 計數
var count = 0;
// 鼠標按下事件
document.body.onmousedown = function (e) {
// 獲取鼠標點擊位置
var x = event.pageX - 18;
var y = event.pageY - 30;
// 分別創建所需要的元素節點
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");
// 通過隨機數從文字數組中獲取隨機下標的文字
var textNode = document.createTextNode(text[parseInt(Math.random() * text.length)]);
// 文字添加到txt節點中
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";
// 將創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);
// 獲取隨機顏色
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;
}
}
// 鼠標抬起事件
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代碼復制到博客側邊欄公告(要開通js權限)如圖:

我用的是第一種方法;第二種我用的有一點小bug所以我選了第一種朋友們可以根據自己的效果選擇
有人更好的效果和方法就和我分享一下子感謝各位老鐵
有錯誤的地方還請糾正我會修改
