原生js鼠标点击特效

        之前网友分享的原生js鼠标点击爱心特效使用还不错,后面发觉这个特效在页面点击输入框、按钮等情况下也有特效，自己又不想点击按钮的时候出现爱心特效，于是自己优化改了一点东西可以支持自己控制不想出现特效的元素.代码如下:

! 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 += 0.004, s[e].alpha -= 0.013, 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) {
            if (e.path[0].getAttribute("noshow") != 'true') 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, 1000 / 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);

添加一个点击验证出现特效过滤:

if (e.path[0].getAttribute("noshow") != 'true') t && t(), o(e)

自己控制不想出现特效的元素 可以在元素上添加标记 noshow="true" 就可以控制点击这个元素不会出现特效。具体效果可以看本页面点赞按钮点击时屏蔽特效。

以上js压缩后的代码

!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+=0.004,s[e].alpha-=0.013,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){if(e.path[0].getAttribute("noshow")!='true')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,1000/60)},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);
