SVG做圆环进度

摘要：哈哈动态效果是用来实现的，，至于进度则是用控制属性实现的。。代码如下首先看下结构加油开始滤镜效果对于不熟悉的，先看下基本教程接下来看下样式最后就脚本了，代码不多，也很简单，就是设置属性圆环进度条谢谢关注

我们要实现的效果：

是不是有点感觉。。。哈哈

动态效果是用css3来实现的，，至于进度则是用js控制stroke-dasharray属性实现的。。

代码如下：

首先看下HTML结构

    

        1143/1566
        加油开始
        99%
        
    

滤镜效果

对于svg不熟悉的，先看下SVG基本教程http://www.runoob.com/svg/svg...

接下来看下CSS样式

.zh-rt-main{position: relative; width: 436px; height: 436px; margin: -36px auto 0;}
.zh-rt-main .zh-node{display: block; position: absolute; z-index: 2; width: 116px; font-size: 12px; text-align: center; opacity: 0;}
.zh-rt-main .zh-node:after{content: ""; display: block; width: 100%; height: 1px; margin-top: 5px;}
.zh-rt-main .zh-node .zh-name,
.zh-rt-main .zh-node .zh-percent-num{display: block;}
.zh-rt-main .zh-node-1{left: 160px; top: 40px; -webkit-animation: fadeIn .3s ease-out .1s forwards; animation: fadeIn .3s ease-out .1s forwards;}
.zh-rt-main .zh-node-2{right: 70px; top: 82px; -webkit-animation: fadeIn .3s ease-out .2s forwards; animation: fadeIn .3s ease-out .2s forwards;}
.zh-rt-main .zh-node-3{right: 20px; top: 138px; -webkit-animation: fadeIn .3s ease-out .3s forwards; animation: fadeIn .3s ease-out .3s forwards;}
.zh-rt-main .zh-node-4{right: 0; top: 195px; -webkit-animation: fadeIn .3s ease-out .4s forwards; animation: fadeIn .3s ease-out .4s forwards;}
.zh-rt-main .zh-node-5{right: 20px; bottom: 135px; -webkit-animation: fadeIn .3s ease-out .5s forwards; animation: fadeIn .3s ease-out .5s forwards;}
.zh-rt-main .zh-node-6{right: 70px; bottom: 75px; -webkit-animation: fadeIn .3s ease-out .6s forwards; animation: fadeIn .3s ease-out .6s forwards;}
.zh-rt-main .zh-node-7{left: 160px; bottom: 31px; -webkit-animation: fadeIn .3s ease-out .7s forwards; animation: fadeIn .3s ease-out .7s forwards;}
.zh-rt-main .zh-node-8{left: 70px; bottom: 75px; -webkit-animation: fadeIn .3s ease-out .9s forwards; animation: fadeIn .3s ease-out .9s forwards;}
.zh-rt-main .zh-node-9{left: 20px; bottom: 135px; -webkit-animation: fadeIn .3s ease-out .8s forwards; animation: fadeIn .3s ease-out .8s forwards;}
.zh-rt-main .zh-node-10{left: 0; top: 195px; -webkit-animation: fadeIn .3s ease-out 1s forwards; animation: fadeIn .3s ease-out 1s forwards;}
.zh-rt-main .zh-node-11{left: 20px; top: 138px; -webkit-animation: fadeIn .3s ease-out 1.1s forwards; animation: fadeIn .3s ease-out 1.1s forwards;}
.zh-rt-main .zh-node-12{left: 70px; top: 82px; -webkit-animation: fadeIn .3s ease-out 1.2s forwards; animation: fadeIn .3s ease-out 1.2s forwards;}

最后就JS脚本了，代码不多，也很简单，就是设置stroke-dasharray属性

// 圆环进度条
function ringProcessBar() {
    var radius = 120;
    var circumference = 2 * radius * Math.PI;
    $(".zh-rt-main").each(function() {
        var curProcess = parseFloat($(this).find(".zh-svg-box .zh-percent").text()).toFixed(2) / 100;
        var dasharray1 = (circumference*(1-curProcess)).toFixed(2);
        var dasharray2 = (circumference*curProcess).toFixed(2);
        $(this).find(".zh-svg-box svg circle:eq(1)").attr("stroke-dasharray", dasharray2+","+dasharray1);
    });
}
ringProcessBar();
