javascript愛心特效
如果是導入文件：
<script src="文件名.js"></script>嵌入代碼里：
<html> <header> <script> !function(e, t, a) {function r() {for (var e = 0; e < s.length; e++) s[e].alpha <= 0 ? (t.body.removeChild(s[e].el), s.splice(e, 1)) : (s[e].y--, s[e].scale += .004, s[e].alpha -= .013, s[e].el.style.cssText = "left:" + s[e].x + "px;top:" + s[e].y + "px;opacity:" + s[e].alpha + ";transform:scale(" + s[e].scale + "," + s[e].scale + ") rotate(45deg);background:" + s[e].color + ";z-index:99999");requestAnimationFrame(r)}function n() {var t = "function" == typeof e.onclick && e.onclick;e.onclick = function(e) {t && t(),o(e)}}function o(e) {var a = t.createElement("div");a.className = "heart",s.push({el: a,x: e.clientX - 5,y: e.clientY - 5,scale: 1,alpha: 1,color: c()}),t.body.appendChild(a)}function i(e) {var a = t.createElement("style");a.type = "text/css";try {a.appendChild(t.createTextNode(e))} catch(t) {a.styleSheet.cssText = e}t.getElementsByTagName("head")[0].appendChild(a)}function c() {return "rgb(" + ~~ (255 * Math.random()) + "," + ~~ (255 * Math.random()) + "," + ~~ (255 * Math.random()) + ")"}var s = [];e.requestAnimationFrame = e.requestAnimationFrame || e.webkitRequestAnimationFrame || e.mozRequestAnimationFrame || e.oRequestAnimationFrame || e.msRequestAnimationFrame ||function(e) {setTimeout(e, 1e3 / 60)},i(".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: fixed;}.heart:after{top: -5px;}.heart:before{left: -5px;}"),n(),r() } (window, document);function initMouse(){var pDom = document.getElementsByTagName("p")[0];pDom.style.cursor = 'move';}? ? ?? </script> </header> <body> <h1>這是特效</h1> </body> </html>總結
